Health benefits, nutrition, diet, and risks
Kale is a green, leafy, cruciferous vegetable that is rich in nutrients. Kale can be good for adding fiber and antioxidants to the diet in many savory dishes, salads, and smoothies.
It is a member of the mustard, or Brassicaceae, family, as are cabbage and Brussels sprouts.
Possible benefits include helping manage blood pressure, boosting digestive health, and protecting against cancer and type 2 diabetes.
This article looks at the nutritional content and health benefits of kale, how to include it in the diet, and reasons why some people should not eat too much of it.
Share on PinterestConsuming kale may help boost digestive health, among other benefits.
Kale contains fiber, antioxidants, calcium, vitamins C and K, iron, and a wide range of other nutrients that can help prevent various health problems.
Antioxidants help the body remove unwanted toxins that result from natural processes and environmental pressures.
These toxins, known as free radicals, are unstable molecules. If too many build up in the body, they can lead to cell damage. This may result in health problems such as inflammation and diseases. Experts believe that free radicals may play a role in the development of cancer, for example.

Diabetes
The American Diabetes Association recommend consuming foods that are rich in vitamins, minerals, fiber, and antioxidants. There is evidence that some of these may offer protection against diabetes.
Fiber: A 2018 study concluded that people who consume the highest amounts of dietary fiber appear to have a lower risk of developing type 2 diabetes. Consuming dietary fiber might also lower blood glucose levels, the authors note.
Antioxidants: Authors of a 2012 article note that high blood sugar levels can trigger the production of free radicals. They note that antioxidants, such as vitamin C and alpha-linolenic acid (ALA), can help reduce complications that may occur with diabetes. Both of these antioxidants are present in kale.
Which foods can help stabilize blood sugar levels?
Heart disease
Various nutrients in kale may support heart health.
Potassium: The American Heart Association (AHA) recommend increasing the intake of potassium while reducing the consumption of added salt, or sodium. This, say the AHA, can reduce the risk of high blood pressure and cardiovascular disease. A cup of cooked kale provides 3.6% of an adult’s daily needs for potassium.
Fiber: A Cochrane review from 2016 found a link between consuming fiber and a lower blood lipid (fat) levels and blood pressure. People who consumed more fiber were more likely to have lower levels of total cholesterol and low-density lipoprotein (LDL), or “bad” cholesterol.
People need both soluble and insoluble fiber. Learn more here about both types.
Cancer
Chlorophyll: Kale and other green vegetables that contain chlorophyll can help prevent the body from absorbing heterocyclic amines. These chemicals occur when people grill animal-derived foods at a high temperature. Experts have linked them with cancer.
The human body cannot absorb much chlorophyll, but chlorophyll binds to these carcinogens and prevents the body from absorbing them. In this way, kale may limit the risk of cancer, and pairing a chargrilled steak with green vegetables may help reduce the negative impact.
Antioxidants: The vitamin C, beta carotene, selenium, and other antioxidants in kale may help prevent cancer. Studies have not found that supplements have the same effect, but people who have a high intake of fruits and vegetables appear to have a lower risk of developing various cancers. This may be due to the antioxidants these foods contain.
Fiber: A high consumption of fiber may help reduce the risk of colorectal cancer, according to a study from 2015.
How does a person’s diet affect their cancer risk? Find out here.
Bone health
Calcium and phosphorus are crucial for healthy bone formation.
Some research has suggested that a high intake of vitamin K may help reduce the risk of bone fractures.
A cup of cooked kale provides almost five times an adult’s daily need for vitamin K, around 15–18% of their calcium need, and about 7% of the daily phosphorus requirement.
Get some more tips on increasing bone density.
Digestion
Kale is high in fiber and water, both of which help prevent constipation and promote regularity and a healthy digestive tract.
Which foods can boost digestion?
Skin and hair
Kale is a good source of beta-carotene, the carotenoid that the body converts into vitamin A as it needs it.
Beta-carotene and vitamin A are necessary for the growth and maintenance of all body tissues, including the skin and hair.
The body uses vitamin C to build and maintain collagen, a protein that provides structure for skin, hair, and bones. Vitamin C is also present in kale.
A cup of cooked kale provides at least 20% of a person’s daily need for vitamin A and over 23% of the daily requirement for vitamin C.
Which other foods can boost hair growth?
Eye health
Kale contains lutein and zeaxanthin, an antioxidant combination that may help reduce the risk of age-related macular degeneration.
Vitamin C, vitamin E, beta-carotene, and zinc also play a role in eye health. All of these are present in kale.

Kale is a crisp and hearty vegetable, with a hint of earthiness. The flavors and nutritional content can vary between types. Younger leaves and summer leaves tend to be less bitter and fibrous.
Curly kale: This is the most commonly available type. It is usually bright green, dark green, or purple, with tight, ruffled leaves that are easy to tear. To remove the leaves from the fibrous stalk, run your hand down the stalk in the direction of growth.
Lacinato or dinosaur kale: This dark blue-green variety is firmer and more robust than curly kale. It is known as dinosaur kale because of its scaly texture. The leaves tend to be longer and flatter and maintain their texture after cooking. Less bitter than curly kale, dinosaur kale is ideal for making kale chips.
Red Russian kale: This is a flat-leaf variety that looks a little like oak leaves. The stalks are slightly purple, and the leaves have a reddish tinge. People may find the stalks too fibrous to eat, but the leaves are sweet and delicate, with a hint of pepper and lemon, almost like sorrel. People can add them raw to salads, sandwiches, and juices, or as a garnish.
Kale grows well in the colder winter months, making a good addition when other fruits and vegetables are less readily available. It is best to cook winter kale, as colder weather can turn the sugars in kale into starch, increasing the bitterness and fiber content.
Serving suggestions
People can eat kale raw, or steam, braise, boil, or sautée it, or add it to soups and casseroles.
Raw: Scrunching the leaves briefly in the hands can make them easier to digest. Add to salads, sandwiches, wraps, or smoothies.
As a side dish: Sauté fresh garlic and onions in olive oil until soft. Add kale and continue to sauté until desired tenderness. Alternatively, steam for 5 minutes, then drain and stir in a dash of soy sauce and tahini.
Kale chips: Remove the ribs from the kale and toss in olive oil or lightly spray and sprinkle with a combination of cumin, curry powder, chili powder, roasted red pepper flakes or garlic powder. Bake at 275°F for 15–30 minutes to desired crispness.
Smoothies: Add a handful of kale to any favorite smoothie. It will add nutrients without changing the flavor very much.
The Environmental Working Group, which assesses a range of products every year, put kale third on their 2019 list of fruits and vegetables most at risk of contamination with pesticides. People should wash kale thoroughly before using it.
Some people should avoid eating too much kale for the following reasons:
Beta-blockers: Doctors often prescribe this type of medication for heart disease. It can increase potassium levels in the blood. People who use beta-blockers should consume high potassium foods, such as kale, in moderation.
Kidney disease: Consuming too much potassium can be harmful to people whose kidneys are not fully functional. If the kidneys cannot remove excess potassium from the blood, consuming additional potassium could be fatal.
Blood thinners: Kale is a rich source of vitamin K, which contributes to blood clotting. This could interfere with the activity of blood thinners, such as warfarin (Coumadin).
Anyone who is taking any of these medications should speak to their doctor about foods to avoid.
Kale is a green, leafy vegetable that provides a wide range of nutrients. It is a healthful addition to a varied diet, and people can use it in numerous ways.

- Brussels sprouts
- Broccoli
Q:
Are foods like kale safe for people with a risk of a blood clot, since it contains so much vitamin K?
A:
Those who are at risk of a blood clot should speak to their doctors about how much vitamin K is appropriate for them.
Those who use blood clotting medications, such as warfarin, should eat similar amounts of vitamin K daily to keep levels consistent, as extra vitamin K will affect the amount of medication they need.
Giving up vitamin K-rich foods is not necessary; it is more about keeping the amounts you consume daily consistent.

Do you like oysters? Eat them and you’ll do your immune system a favor.
Did you know that a healthy amount of zinc in your diet has been linked to an improved immune system and faster wound healing? The benefits of getting enough zinc don’t stop there.
Research has also found that zinc may help in these situations:
Shorten the common cold. When taken as an over-the-counter supplement, zinc reduced the severity and duration of the common cold, reported a meta-analysis. A systematic review published in July 2020 in The American Society of Tropical Medicine and Hygiene found that zinc supplementation could potentially reduce the length of the common cold by 2.25 days.
Fend off heart disease. In a preliminary lab study published in July 2015 in the Journal of Biological Chemistry, researchers found that zinc may play an important role in regulating the heartbeat — a potential advancement in the fight against arrhythmia-related heart failure. For the study, scientists used cardiac tissue from sheep hearts when observing these benefits, so more research in humans is needed before it’s clear that eating foods with zinc would produce these results for people. Another study, published in May 2020 in Lipids in Health and Disease, found that supplementing with zinc and magnesium for 12 weeks helped people with type 2 diabetes and coronary heart disease decrease insulin and fasting blood sugar levels and increase HDL (“good”) cholesterol, though the study was small, with only 60 participants, and the study authors noted that more research is needed.
Treat hypothyroidism. Researchers have observed that zinc positively affected thyroid function in a study published online in 2015 in the Journal of the American College of Nutrition of a small group of overweight women with hypothyroidism.
Improve eye health. Specifically, supplemental zinc may help slow the progression of age-related macular degeneration, according to the National Institutes of Health (NIH).
Support wound healing. As mentioned, zinc may aid the healing of wounds by reducing inflammation and activating immune cells at the area of injury, per research cited in an article published in January 2018 in Nutrients.

Can Adding These Foods to My Diet Help Prevent Illnesses Like the Novel Coronavirus?
Another hot topic: zinc’s effect on COVID-19. The data is inconclusive at this point, according to the NIH.
But it seems that being deficient in zinc could worsen symptoms if you do test positive for COVID-19. A small study published in November 2020 in the International Journal of Infectious Diseases found that a significant number of people with COVID-19 were also deficient in zinc and that the zinc-deficient individuals developed more complications than those who were not deficient in the mineral. That said, more studies are needed to know the true relationship between zinc deficiency and COVID-19.
Unfortunately, it seems that starting to take zinc once you’re diagnosed won’t help. According to a trial published in February 2021 in JAMA Network Open, supplementing with zinc did not lessen COVID-19 symptoms among patients who’d been diagnosed.

Daily intake of zinc for men – 11 mg, for women (except during pregnancy and lactation) – 8 mg.
1. Red meat
Any meat is a source of zinc
, but only beef, lamb and pork contain enough zinc. For example, 100 grams of raw minced meat from the listed types of meat contains 4.8 mg of zinc, which is 44% of the daily value. Red meat also has other beneficial substances: iron, B vitamins and creatine.
But keep in mind that eating a lot of red meat, especially fried meat, is associated with an increased risk of heart disease. However, as long as you eat red meat in moderation and as part of a diet rich in fruits, vegetables, and fiber, you have nothing to worry about.
2. Shellfish
Shellfish is a healthy and low-calorie food and the main source of zinc. Oysters contain the most zinc, with a serving of six oysters averaging about 32 mg of zinc, or 291% of the daily value.
Shrimps and mussels are also rich in zinc: 100 grams of these seafood contain 14% of the daily value.
3. Legumes
Legumes (such as chickpeas, lentils and beans) also contain a significant amount of zinc: in 100 grams of finished lentils – about
12% of the daily value.
But keep in mind: legumes contain phytates, these substances interfere with the absorption of zinc and other minerals. That is, zinc from legumes is not as well absorbed as, for example, from animal products. Despite this, legumes are an important source of zinc, especially for people who follow a vegan or vegetarian diet. By the way, heating or soaking legumes increases the bioavailability (absorption by the body) of this mineral.
4. Seeds
The seeds help increase your daily zinc intake (but can ruin your smile if consumed in excess). For example, three tablespoons (30 grams) of pumpkin or sesame seeds contain 31% and 43% of the recommended daily intake for men and women.
Seeds are a good source of fiber, healthy fats and vitamins, so it’s wise to include them in your diet at least a couple of times a week.
5. Nuts
Including nuts (especially pine nuts, peanuts, almonds, and cashews) in your diet can significantly increase your zinc intake. For example,
a handful of almonds (28 grams) contains 15% of the daily value of
.
Nuts have been shown to reduce the risk of heart disease, cancer and diabetes.
6. Dairy products
Dairy products provide all kinds of nutrients to the body, including zinc.
Milk and cheese are the most popular sources of zinc as they are high in the bioavailable mineral. For example, 100 grams of cheddar cheese contains about 28% of the daily value of zinc, and one cup of whole milk contains about 9% of the daily intake of zinc.
In addition, dairy products are good for bone health due to protein, calcium and vitamin D.
7. Eggs
Eggs contain a moderate amount of zinc. One large chicken egg contains about 5% of the daily requirement of this trace element. And eggs are a source of B vitamins, selenium and choline, which most people lack.
8. Cereals
Some whole grain products such as wheat, rice and oats
contain zinc
. However, just like legumes, whole grains contain phytates that impair zinc absorption. Therefore, relying on cereals as the sole source of zinc is not recommended.
Grains are also a source of other important nutrients: fibre, B vitamins, magnesium, iron, phosphorus, manganese and selenium.
9. Vegetables (at least some of them)
In general, vegetables and fruits are not rich enough in zinc to make up for its lack in the body. However, some of them still contain enough zinc and will help maintain normal levels (especially if you do not eat meat).
Potato (one large tuber) contains about 1 mg of zinc, which is 9% of the daily value. Zinc is found in cabbage (about 3% of the daily value per 100 grams).
10. Dark chocolate
Dark chocolate also contains zinc.
A 100-gram bar of 70-85% chocolate
contains about 3.3 mg of zinc, or 30% of the daily requirement.
Of course, not everyone will take the risk of eating 100 grams of dark chocolate at a time, because in addition to the high content of zinc, you will get another 600 extra calories. Therefore, we recommend limiting ourselves to 10-20 grams of dark chocolate per day – as a pleasant and healthy addition to the diet.
