What foods should be avoided while taking letrozole. How does letrozole interact with certain foods. What dietary precautions should breast cancer patients on letrozole take. How can patients optimize their diet while undergoing letrozole treatment.

Understanding Letrozole: A Crucial Breast Cancer Treatment

Letrozole is a powerful medication primarily used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. This aromatase inhibitor works by reducing the production of estrogen in the body, which can fuel the growth of certain types of breast cancer.

While letrozole is highly effective in treating and preventing the recurrence of breast cancer, patients need to be aware of potential interactions between this medication and certain foods. Understanding these interactions can help optimize treatment efficacy and minimize side effects.

Key Facts About Letrozole

• Typically prescribed as a 2.5mg tablet taken once daily
• Treatment duration usually ranges from 5 to 10 years
• Common side effects include hot flashes, fatigue, and mood changes
• Regular monitoring of blood pressure, cholesterol, and bone density is essential

Foods That May Interfere with Letrozole Absorption

While the original text doesn’t specifically mention food interactions, it’s important to consider potential dietary factors that could affect letrozole’s efficacy. Some foods may interfere with the absorption or metabolism of letrozole, potentially reducing its effectiveness.

Grapefruit and Grapefruit Juice

Grapefruit and its juice contain compounds that can inhibit enzymes responsible for metabolizing certain medications, including letrozole. This interaction may lead to increased levels of the drug in the bloodstream, potentially exacerbating side effects.

High-Fat Meals

Consuming large amounts of dietary fat alongside letrozole may affect its absorption. While the medication can be taken with or without food, it’s advisable to maintain a consistent eating pattern to ensure steady drug levels in the body.

Dietary Considerations for Optimal Letrozole Efficacy

To maximize the benefits of letrozole treatment, patients should focus on maintaining a balanced and nutritious diet. This approach can help mitigate side effects and support overall health during cancer treatment.

Calcium-Rich Foods

Letrozole can affect bone density, making it crucial to include calcium-rich foods in the diet. Good sources include:

• Low-fat dairy products
• Leafy green vegetables
• Fortified plant-based milk alternatives
• Canned fish with soft bones (e.g., sardines)

Vitamin D Sources

Adequate vitamin D intake is essential for calcium absorption and bone health. Include the following in your diet:

• Fatty fish (salmon, mackerel, tuna)
• Egg yolks
• Fortified foods (cereals, orange juice)

Sunlight exposure and supplementation may also be recommended by your healthcare provider.

Managing Side Effects Through Diet

Certain dietary strategies can help alleviate some of the common side effects associated with letrozole treatment.

Combating Hot Flashes

To help manage hot flashes, consider:

• Reducing caffeine and alcohol intake
• Staying hydrated with cool water
• Incorporating foods rich in phytoestrogens (e.g., soy products, flaxseeds) after consulting with your oncologist

Addressing Fatigue

Combat fatigue by focusing on energy-boosting foods:

• Complex carbohydrates (whole grains, legumes)
• Lean proteins
• Iron-rich foods (lean meats, spinach, beans)
• Staying well-hydrated

Supplements and Letrozole: Proceed with Caution

While dietary supplements may seem beneficial, they can potentially interact with letrozole or affect its efficacy. Always consult your healthcare provider before starting any new supplements.

Supplements to Avoid

Exercise caution with the following supplements:

• St. John’s Wort
• High-dose antioxidants
• Soy or red clover supplements
• Herbal products marketed for menopausal symptoms

Maintaining a Healthy Weight During Letrozole Treatment

Weight management is crucial during letrozole treatment, as excess body fat can produce estrogen, potentially counteracting the medication’s effects.

Strategies for Healthy Weight Maintenance

• Focus on nutrient-dense, low-calorie foods
• Practice portion control
• Incorporate regular physical activity (as approved by your healthcare team)
• Stay hydrated with water and unsweetened beverages

The Role of Alcohol in Letrozole Treatment

While moderate alcohol consumption may be permissible for some patients, it’s essential to discuss this with your healthcare provider. Alcohol can potentially interact with letrozole and may increase the risk of certain side effects.

Potential Risks of Alcohol Consumption

• Increased risk of liver problems
• Exacerbation of hot flashes
• Interference with sleep quality
• Potential impact on bone health

If you choose to consume alcohol, do so in moderation and only after consulting with your oncologist.

Creating a Supportive Meal Plan

Developing a meal plan that supports your letrozole treatment can help ensure you’re getting the necessary nutrients while avoiding potential food interactions. Consider the following tips:

Meal Planning Strategies

• Incorporate a variety of colorful fruits and vegetables
• Choose lean proteins (fish, poultry, legumes)

• Include healthy fats (avocado, nuts, olive oil) in moderation
• Prepare meals in advance to ensure balanced nutrition even on busy days

Working with a registered dietitian who specializes in oncology nutrition can provide personalized guidance tailored to your specific needs and treatment plan.

The Importance of Hydration During Letrozole Treatment

Proper hydration is crucial for patients taking letrozole, as it can help manage side effects and support overall health.

Benefits of Staying Hydrated

• May help reduce the severity of hot flashes
• Supports kidney function and toxin elimination
• Can alleviate constipation, a potential side effect of letrozole
• Helps maintain energy levels and combat fatigue

Hydration Tips

To ensure adequate hydration:

• Aim for 8-10 glasses of water per day
• Include hydrating foods like cucumbers, watermelon, and soups in your diet
• Limit caffeine and alcohol intake, as they can contribute to dehydration
• Consider herbal teas or infused water for variety

Managing Gastrointestinal Side Effects Through Diet

Some patients may experience gastrointestinal side effects while taking letrozole. Dietary modifications can help alleviate these symptoms.

Addressing Nausea and Loss of Appetite

To combat nausea and stimulate appetite:

• Eat small, frequent meals throughout the day
• Choose bland, easily digestible foods
• Incorporate ginger or peppermint tea, which may have anti-nausea properties
• Avoid strong odors that may trigger nausea

Managing Constipation

To prevent or alleviate constipation:

• Increase fiber intake through fruits, vegetables, and whole grains
• Stay well-hydrated
• Consider probiotic-rich foods like yogurt or kefir
• Engage in regular physical activity, as approved by your healthcare team

The Role of Antioxidants in Letrozole Treatment

While antioxidants are generally considered beneficial for overall health, their role in cancer treatment is complex and sometimes controversial.

Balancing Antioxidant Intake

When it comes to antioxidants during letrozole treatment:

• Focus on obtaining antioxidants from whole food sources rather than supplements
• Include a variety of colorful fruits and vegetables in your diet
• Consult with your oncologist before taking high-dose antioxidant supplements
• Be aware that some antioxidants may potentially interfere with cancer treatments

Your healthcare provider can offer personalized guidance on antioxidant intake based on your specific treatment plan and overall health status.

Navigating Social Situations and Dining Out

Maintaining a social life and enjoying meals out can be an important part of quality of life during cancer treatment. However, it’s essential to navigate these situations mindfully while taking letrozole.

Tips for Dining Out

• Research restaurant menus in advance to identify suitable options
• Don’t hesitate to ask about ingredients or preparation methods
• Choose grilled, baked, or steamed dishes over fried options
• Be mindful of portion sizes and consider sharing dishes or taking leftovers home
• Avoid or limit alcohol consumption

Handling Social Pressure

To manage social situations where food or drink may be a focus:

• Communicate your dietary needs to friends and family
• Offer to bring a dish you know you can eat to gatherings
• Practice polite ways to decline food or drinks that may interfere with your treatment
• Focus on the social aspect of gatherings rather than the food

The Importance of Consistent Medication Timing

While dietary considerations are crucial, it’s equally important to maintain consistent timing when taking letrozole. This ensures steady drug levels in the body and optimizes treatment efficacy.

Strategies for Medication Adherence

• Set a daily alarm or reminder on your phone
• Use a pill organizer to keep track of doses
• Associate taking the medication with a daily routine (e.g., breakfast or bedtime)
• Keep a medication log to record doses and any side effects

If you miss a dose, take it as soon as you remember, unless it’s close to your next scheduled dose. Never double up on doses to make up for a missed one.

Monitoring Nutritional Status During Letrozole Treatment

Regular monitoring of your nutritional status can help identify and address any deficiencies that may arise during letrozole treatment.

Key Nutrients to Monitor

• Vitamin D and calcium for bone health
• Iron to combat fatigue
• B vitamins for energy metabolism
• Omega-3 fatty acids for overall health and potentially reducing inflammation

Your healthcare team may recommend periodic blood tests to assess your nutritional status and adjust your diet or supplementation as needed.

Empowering Yourself Through Nutrition Education

Taking an active role in your nutrition during letrozole treatment can enhance your overall well-being and potentially improve treatment outcomes.

Resources for Further Learning

• Consult with a registered dietitian specializing in oncology nutrition
• Attend nutrition workshops or support groups for breast cancer patients
• Explore reputable online resources from cancer organizations and research institutions
• Keep a food diary to track your intake and identify patterns or potential issues

Remember that your nutritional needs may change throughout your treatment journey. Stay in close communication with your healthcare team and be proactive in addressing any concerns or questions about your diet and letrozole treatment.

Letrozole: medicine used for treating breast cancer

1. About letrozole

Letrozole is a medicine used for treating breast cancer. It can also help prevent breast cancer coming back.

It is mainly prescribed for women who have been through the menopause and have a type of cancer called “hormone-dependent” breast cancer.

Most people who take letrozole will have had surgery, radiotherapy or sometimes chemotherapy to treat their breast cancer first.

Letrozole comes as tablets. It is available on prescription only.

Letrozole can sometimes also be used:

• to prevent breast cancer if you are high risk and have been through the menopause
• to treat breast cancer in men and younger women
• as a fertility treatment if you have polycystic ovary syndrome

2.

Key facts

• You usually take letrozole once a day – try to take it at the same time each day.
• Most people are given letrozole for 5 years, but some will take it for up to 10 years.
• Common side effects can be like menopause symptoms and include hot flushes, difficulty sleeping, tiredness and low mood.
• Side effects usually improve after a few months as your body gets used to the medicine.
• Your doctor will monitor your blood pressure, cholesterol levels and bone density during your treatment.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.

These are not all the side effects of letrozole. For a full list, see the leaflet inside your medicines packet.

Information:

You can report any suspected side effect to the UK safety scheme.

6. How to cope with side effects of letrozole

Menopause symptoms such as hot flushes, difficulty sleeping, tiredness and low mood usually improve during the first months of taking letrozole. However, if they’re severe or last longer than a few months, talk to your doctor or breast cancer nurse.

Information:

Find out more about treating symptoms of the menopause.

What to do about:

• hot flushes and sweating – try cutting down on spicy food, caffeine, smoking and alcohol. It may help to keep the room cool and use a fan. Try spraying your face with cool water, or sipping a cold drink.
• dry or itchy vagina, bleeding from your vagina – ask your doctor or breast cancer nurse to recommend a vaginal moisturiser for treating irritation or dryness. Vaginal bleeding usually happens in the first few weeks after starting letrozole. Talk to your doctor if it lasts longer than a few days. Also talk to your doctor if these symptoms first appear more than a few weeks after you start taking letrozole.
• difficulty sleeping – avoid caffeine (tea, coffee, cola and chocolate) in the afternoon and evening. Keep your bedroom dark and quiet, and try going to bed and getting up at a set time each day. Stop watching TV and using electronic devices like mobiles or tablets at least 1 hour before bedtime.
• feeling very tired – gentle exercise and eating healthily can help make you feel less tired. Try going to bed and getting up at a set time each day. Do not drive, ride a bike or operate machinery if you feel very tired while taking letrozole. Speak to your doctor if this problem does not gradually improve as your body gets used to the medicine.
• feeling or being sick, loss of appetite – it might help to take letrozole after you’ve eaten. Choose foods you normally enjoy but avoid rich or spicy food. Try eating smaller meals but more often. If you’re being sick, have small frequent sips of water to avoid dehydration. Talk to your doctor if your symptoms do not improve or get worse.
• mild aches in your muscles or bones – ask a pharmacist to recommend a suitable painkiller. If the pain lasts more than a week ask your doctor for advice. If you have a sudden attack of pain in a joint ask a doctor for advice urgently.
• numb or tingling hands – stop taking the medicine and ask your doctor for advice
• changes to your skin, including a rash – it may help to take an antihistamine. You can buy these at a pharmacy without a prescription. Check with a pharmacist to see what is suitable for you.
• hair loss – some people find their hair gets thinner when they start taking letrozole. This is usually mild. Ask your breast cancer nurse for advice if this is bothering you.
• low mood or depression – it is difficult to know whether this is due to the medicine, dealing with menopausal symptoms or dealing with a diagnosis of cancer. Speak to your doctor or specialist nurse. They may recommend therapies, like cognitive therapy or mindfulness, or antidepressant medicines.

7. Pregnancy and breastfeeding

Letrozole is not recommended when pregnant or breastfeeding. This is because it can harm your baby.

Talk to your doctor urgently if there is any chance that you could be pregnant.

Non-urgent advice: Tell your doctor if you’re:

• pregnant
• trying to get pregnant
• breastfeeding

8.

Cautions with other medicines

There are very few medicines that interfere with the way letrozole works in the body.

However, do not take any medicines like hormone replacement therapy that relieve menopausal symptoms. These may contain ingredients similar to the hormone oestrogen and could stop letrozole working as well as it should in treating your cancer.

Mixing letrozole with herbal remedies and supplements

Do not take any herbal remedies or supplements for menopausal symptoms while taking letrozole. These can stop letrozole working as well as it should.

There’s very little information about taking other herbal remedies and supplements together with letrozole.

Important

Tell your doctor and pharmacist if you’re taking any other medicines, including herbal remedies, vitamins or supplements.

9. Common questions

How does letrozole work?

Letrozole belongs to a group of medicines called aromatase inhibitors.

Aromatase inhibitor medicines are used to treat certain types of breast cancer, where the cancer cells need oestrogen (a hormone) in order to grow.

After the menopause your ovaries stop producing oestrogen. Instead your body makes oestrogen from an enzyme called aromatase.

Aromatase inhibitors reduce the amount of aromatase in your body and this in turn stops your body producing oestrogen. This helps prevent cancer cells growing, as they no longer have anything to feed on.

What are the benefits of taking letrozole?

Letrozole helps stop your breast cancer coming back. By taking this medicine for 5 years (or sometimes up to 10 years), you have a better chance of being alive 15 years after your breast cancer was first diagnosed.

Your specialist will be able to explain the benefits and risks of taking letrozole.

They can also calculate how well letrozole is likely to work for you. This is done by comparing your details with those of more than 20,000 other people who have had treatment for breast cancer.

The exact benefits and how well it’s likely to work for you depend on a combination of different things.

This varies for each person and includes factors like your age when the breast cancer was found, how it was found and whether you’ve had chemotherapy or not.

How long does it take to work?

Letrozole will immediately start to reduce the amount of oestrogen in your body.

However, it takes several weeks or months for the medicine to work fully.

During this time you’re likely to have menopause symptoms as your body gets used to having less oestrogen. These symptoms will gradually improve as your body adjusts to the medicine.

How long will I take it for

Most people who take letrozole will have had surgery, radiotherapy or sometimes chemotherapy to treat their breast cancer first.

In this case, surgery, radiotherapy or chemotherapy is the first (“primary”) treatment and letrozole is an additional (“adjuvant”) therapy. Adjuvant therapy helps stop the cancer coming back.

Most people will have adjuvant therapy for 5 years. However, sometimes your doctor will advise continuing it for longer. During this time you may be given letrozole only, or tamoxifen (a drug that can also be used to treat breast cancer) for a few years followed by letrozole for the remaining time.

Letrozole is sometimes used to treat cancer if you cannot have surgery, or to shrink the cancer before surgery if you cannot have chemotherapy. In this case your specialist will tell you how long to take the medicine for.

Is it safe to take for a long time?

Letrozole is generally safe to take long term, however, your specialist team will monitor your health carefully.

This is because letrozole reduces levels of oestrogen that your body needs for strong and healthy bones. If you take letrozole for a long time your bones can become weaker (osteoporosis) and more likely to break.

You will have bone density scans before you start taking letrozole, 1 or 2 years into treatment and again after you finish your treatment.

Your doctor may recommend a type of medicine called a bisphosphonate to help reduce bone damage. They can also give you advice on exercise and diet to help keep your bones strong.

Letrozole can also increase your blood pressure and cholesterol levels. Your doctor will monitor these during your regular check-ups and recommend treatment as needed.

Can I stop taking it?

Important

Do not stop taking letrozole without talking to your doctor first.

If you want to stop taking it for any reason, your doctor will be able to discuss alternatives for treating your breast cancer or preventing it coming back.

Sometimes people are given a short break from letrozole. This can help if you are getting side effects such as joint pain. However, only take a break from your medicine if you have discussed it with your specialist first and they agree to it.

Are there other medicines like letrozole?

Medicines such as tamoxifen, anastrazole and exemestane work in a similar way to letrozole. These medicines lower your oestrogen levels and can cause similar side effects.

However, medicines affect people in different ways. If you are bothered by side effects from taking letrozole, talk to your doctor. They may want to try you on one of these other medicines instead.

Can I drink alcohol with it?

There is no evidence that drinking alcohol causes any problems when taking letrozole.

Some people taking letrozole may get hot flushes or redness when they drink alcohol. In this case, avoiding alcohol may help.

Is there any food or drink I need to avoid?

Most people can eat and drink normally when taking letrozole. Although some people may get hot flushes or redness when they drink alcohol.

Some people find letrozole affects their appetite.

If you lose your appetite, try to make sure you have a balanced diet by eating smaller meals and more often.

If it makes you feel hungrier and you’re putting on too much weight, ask your doctor or specialist nurse to refer you to a dietitian.

Will it affect my contraception or fertility?

Letrozole is generally only given to you if you have gone through the menopause.

However, some people find they start having periods again after taking letrozole. If this happens to you, it’s important to use reliable contraception. Talk to your doctor if your periods start again, or if there is any chance that you are pregnant.

Letrozole is not recommended during pregnancy.

Can I drive or ride a bike?

Some people feel extremely tired when taking letrozole.

If you feel tired or dizzy, or if you get blurred vision, do not drive, cycle or operate machinery until you feel OK again.

Breast cancer is estimated to be the most prevalent type of cancer, impacting millions of women worldwide each year.  

Breast cancer treatment has come a long way in recent decades, which fortunately has improved the prognosis and survivability of breast cancer.

Letrozole is one of many medications used to treat breast cancer. 

While it’s primarily intended to treat breast cancer, letrozole can be used for other reasons as well.

If you’ve been prescribed letrozole, you might wonder if there are any specific foods you should eat or avoid while taking it. Keep reading to learn more.

What is Letrozole (Femara)?

Letrozole is a medication in a class of drugs called nonsteroidal aromatase inhibitors. The common brand name of letrozole is Femara.

The Food and Drug Administration approved Letrozole in 1998. Per the FDA, letrozole is “indicated for first-line treatment of postmenopausal women with hormone receptor-positive or unknown, locally advanced or metastatic breast cancer.”

Letrozole might be used to help shrink breast cancer before surgically removing the tumor or before starting additional therapy like chemotherapy.

Letrozole comes in 2.5-milligram tablets, and the dosing schedule will depend on its use. The typical dosage of letrozole is one 2.5 milligram tablet daily for breast cancer. If it’s used for ovulation induction (more on that soon), the dose is usually 2.5-7.5 milligrams daily.

Letrozole works to decrease the amount of estrogen your body produces. Estrogen is the primary female sex hormone and is primarily produced by the female ovaries. The three primary types of estrogen in the female body are estrone, estradiol, and estriol. 

Aromatase is an enzyme that changes non-estrogen sex hormones like testosterone into estrogen, so aromatase inhibitors block this process from occurring, thereby reducing estrogen production.

How does Letrozole work?

Letrozole is commonly prescribed to treat conditions impacted by estrogen levels, such as certain types of breast cancer. Letrozole is typically prescribed to women who have undergone menopause and who also have a specific type of “hormone-dependent” breast cancer.

Estrogen plays a large role in breast cancer. Around 75% of breast cancers are estrogen receptor-positive, meaning the hormone estrogen feeds them. 

Medications like letrozole can help eliminate estrogen production, helping to slow the growth and metastasis of certain types of breast cancers.

If you don’t have estrogen-receptor-positive breast cancer, letrozole won’t be effective in treating your breast cancer.  Letrozole might be used to help prevent breast cancer in certain high-risk post-menopausal women.

Letrozole is also used as a fertility treatment for women with polycystic ovary syndrome (PCOS), a hormonal imbalance that can disrupt the normal ovulation pattern. 

Many women with PCOS have estrogen dominance, which can block the production of important hormones necessary for ovulation. Letrozole helps reduce estrogen levels to promote hormones that allow ovulation to occur.

Letrozole might also be used in combination with other fertility medications during a cycle of in-vitro fertilization (IVF), an infertility treatment used to attain pregnancy.

Side effects and risks of taking letrozole

There are potential side effects and risks of taking letrozole. Some of the most common side effects of taking letrozole have to do with reduced estrogen levels and include:

• Back pain
• Bone/joint pain
• Hot flashes (sudden sweating and feeling of warmth)
• Muscle pain

Other side effects that might occur less often include:

• Taste changes
• Hair thinning
• Dry skin
• Weight gain
• Increased appetite
• Mood changes
• Skin or eye redness

There may be an increased risk of osteoporosis from taking letrozole. Estrogen plays a role in bone density. 

Low estradiol levels are associated with a 2.5-fold increased risk of bone fractures in older women, independent of their age or weight.

Long-term use of letrozole may negatively impact your bone density, which increases your risk of fractures.

Foods to avoid while taking Letrozole 

Some foods and supplements may tend to raise estrogen levels. Eating large amounts of these types of foods might counteract the action of letrozole and reduce its effectiveness.

In general, though, there aren’t any specific foods to avoid while taking letrozole, unless otherwise indicated by your healthcare provider.

Some foods contain phytoestrogens, which are compounds from plant-based foods that resemble estrogen. 

The four main types of phytoestrogens are isoflavones, stilbene, coumestan, and lignan. However, some of these phytoestrogens work to reduce estrogen levels and may be beneficial.

For instance, the use of isoflavones in adolescence is associated with a reduced risk of breast cancer. Studies conclude that the effect of phytoestrogens on hormone levels (like estrogen) is inconclusive and dependent on the stage of life and specific health conditions.

Potential foods to avoid if you’re taking letrozole for PCOS

If you’re taking letrozole to induce ovulation for PCOS, you might have insulin resistance. Improving insulin resistance can promote more stable hormone levels and might help you manage your PCOS without medications.

To help improve insulin resistance, consider reducing your intake of refined carbohydrates, including those with added sugars. 

Some examples of refined carbohydrates to avoid include:

• Sweets and desserts (cake, ice cream, muffins, etc.)
• Bread products made with refined/enriched grains (white bread, white bagels, white pasta, etc.)
• White rice
• Foods with added sugar (flavored yogurt, cold cereal, certain nutrition bars)
• Sugary drinks (soda, sweetened coffee and tea, energy drinks, etc.)

Potential foods to avoid if you’ve been told to reduce your intake of phytoestrogens

While the connection between dietary phytoestrogens and estrogen levels can vary (some may lower estrogen), here are the most common phytoestrogens to be aware of if your healthcare provider wants you to avoid phytoestrogens:

• Soybeans
• Kidney beans
• Peas/lentils
• Flaxseed
• Sunflower seeds
• Peanuts
• Wheat bran
• Barley

Potential foods to avoid if you’re taking letrozole long-term

Taking letrozole long-term can result in reduced bone density. To help prevent further bone loss, consider eating fewer high-sodium foods. 

High-sodium foods are generally more processed and contain much more sodium than you’d typically add to your food in the form of table salt.

A high-sodium diet can cause your body to lose calcium and promote unwanted bone loss. 

Avoid high-sodium, processed foods like:

• Deli and cured meats
• Salty snacks (chips, pretzels, etc.)
• Quick-bread mixes
• Canned soups
• Frozen entrees
• Fast food like pizza, salted French fries, etc.

You may also want to limit beans and legumes if you’re at risk of osteoporosis because the phytates in beans and legumes can reduce calcium absorption. To reduce the phytate content of legumes, soak them in water for several hours before cooking them in fresh water.

Foods to eat while taking Letrozole

Eating a whole food, primarily plant-based diet can help support your health while taking letrozole. If you have breast cancer (the most common reason letrozole is prescribed), it’s important to maintain healthy lifestyle habits both during and after cancer treatment.

Eating Mediterranean-style meals and snacks might help you reduce your future cancer risk. The nutrient- and antioxidant-rich Mediterranean diet can help reduce inflammation and cancer incidence. 

If you’re going to have chemotherapy after taking letrozole, it’s important to support your health as best you can in the waiting period. Chemotherapy can deplete nutrient stores, so try to build up those nutrient stores as best you can while taking letrozole.

Unless you’ve been advised to avoid a specific food by your healthcare provider, here are some generally healthy foods to eat while taking letrozole:

Fruits and vegetables

All types of fruits and vegetables are ideal to eat when taking letrozole. Aim to get a variety of colors to get different antioxidants, which help your body fight inflammation and cell damage. Some fruits and vegetables particularly high in antioxidants include:

• Berries (blueberries, blackberries, raspberries, and strawberries)
• Kidney and pinto beans
• Dark green leafy vegetables
• Orange vegetables like carrots and pumpkin

Whole grains

Whole grains contain more fiber, protein, and micronutrients than refined grains. In addition, studies show that people with higher fiber intakes tend to have healthier estrogen levels.

Choose high-fiber whole grains like:

• Whole wheat bread or grains made with whole wheat flour
• Brown rice
• Barley
• Whole oats

Healthy fats

Healthy unsaturated fats can be a source of omega-3 fatty acids, which help combat inflammation.

• Avocados
• Nuts
• Seeds
• Oily fish (salmon, mackerel, anchovies, etc.)

Lean protein

Taking letrozole might increase the amount of cholesterol in your blood (hypercholesterolemia). High cholesterol levels are a risk factor for heart disease. 

To help combat this effect, try to choose a protein that is lower in saturated fat, like:

• Fish
• Chicken
• Legumes
• Eggs
• Lean cuts of red meat (pork loin, 90% lean beef, etc.)

Other things to avoid while taking Letrozole

Alcohol

While letrozole doesn’t negatively interact with alcohol, it might still be a good idea to abstain from it. 

Estrogen levels tend to be higher in women who drink alcohol than those who don’t. Since letrozole reduces estrogen levels, you may want to limit your alcohol consumption while taking it.

Supplements with estrogen

You should avoid any supplement containing any form of estrogen while taking letrozole. Taking estrogen while on letrozole counteracts the purpose and may lessen letrozole’s effectiveness.

Xenoestrogens

Xenoestrogens are a group of endocrine disruptors (things that negatively impact your hormones) that mimic estrogen.  

Some sources of xenoestrogens to avoid while taking letrozole include:

• Fruits and vegetables sprayed with certain pesticides
• Certain plastics
• Certain ingredients in makeup and nail polishes

Should Letrozole be taken with food?

You can take letrozole with or without food. While nausea isn’t a common side effect of letrozole, there is still a chance you might feel sick from taking letrozole. If that happens, taking letrozole with food can help reduce the stomach upset it causes.

What is the best time to take Letrozole?

It doesn’t matter what time of day you take letrozole. The more important thing is to take it at the same time consistently from day to day. For instance, if you choose to take it in the morning, try to always take it in the morning.

How to reduce the side effects of Letrozole

• Use over-the-counter pain medications as needed for potential joint and muscle pain, such as aspirin, ibuprofen, or acetaminophen. Consider taking a warm bath to ease sore muscles. Exercise can also ease joint pain from letrozole.
• You might notice hair thinning from taking letrozole. According to a study, supplementation with vitamin C and omega-3 fatty acids may help counteract letrozole-related hair thinning.
• If you experience hot flashes from letrozole, try setting the thermostat to a cooler temperature, wear light, breathable clothing, and utilize lightweight bedding and fans to help keep you comfortable.

Natural aromatase inhibitors

Some foods have natural aromatase-inhibiting qualities, which means they may exert a weaker but similar effect as letrozole.

1) Flavonoids

Flavonoids are among the most commonly tested compounds to assess their natural aromatase inhibitor properties. Flavonoids are compounds found in plant foods like fruits, vegetables, grains, tea, wine, and more.

Some of the richest flavonoid foods are:

• Berries
• Red cabbage
• Onion 
• Kale
• Tea
• Red wine
• Dark chocolate
• Soybeans

2) Chrysin

According to a study, this flavonoid is found in honey and passionflower and exhibits aromatase-inhibiting properties. Chrysin supplements are also available for a more potent dosage. 

Another study found that chrysin can help slow breast cancer growth and kill breast cancer cells. The researchers concluded that chrysin might be a promising therapeutic option in addition to other breast cancer treatments or drugs.

3) White mushrooms

In a study, white mushrooms inhibit aromatase activity, making them a potential natural aromatase inhibitor.

Conclusion

Letrozole is a medication that blocks aromatase, an enzyme that increases estrogen levels. 

Letrozole is most commonly used to treat certain types of breast cancer but is also used as a fertility drug to induce ovulation.

Studies have shown inconsistent results regarding which foods might increase estrogen levels and which can decrease estrogen levels. In general, it’s advisable to focus on eating a high-fiber diet rich in plant-based foods to support healthy hormone levels.

You may want to consider limiting alcohol while taking letrozole, as well as any other particular foods your healthcare provider recommends in your specific case.

PET/CT preparation – PET Technology

PET/CT is a modern, high-tech method for diagnosing cancer. Its accuracy largely depends on compliance with the rules of preparation for the study. Any effect on the body that changes the metabolism can distort the results of research. When making an appointment for the procedure, we recommend that you take into account that the stay in the center can take from 2 to 5 hours.

18F-FDG PET/CT PREPARATION AND PATIENT AID

• 1. Exam is done on an empty stomach

     Eliminate alcohol and drugs containing alcohol 48 hours before the exam.
     Eliminate carbohydrates the day before the study. You can not: sweet, flour, vegetables, fruits, cereals, milk. You can: cottage cheese or sour-milk products, boiled lean meat, boiled fish.
     The procedure is performed strictly on an empty stomach, the last meal is recommended at least 6 hours before the examination.
     When preparing for the examination, try to drink as much as possible: water, coffee and tea without added milk and sugar. Water should be clean drinking, strictly without gas and sweeteners. On the eve of diagnosis with 18F-FDG, a light carbohydrate-free dinner and a large amount of warm water (without gas) are recommended.

     Immediately before the study, after the administration of the radiopharmaceutical, it is essential to drink plenty of water – the quality of the imaging depends on this.

  2. Consult your doctor

     People with diabetes who plan to have a PET/CT procedure should consult with their physician or PET/CT specialist to avoid inaccurate results or complications during the procedure.

  3. Avoid hypothermia

     Do not supercool 36 hours before the PET/CT procedure to avoid activation of metabolic processes in adipose tissue – this may affect the diagnostic results.
