What is a good A1C level for diabetes control. How does A1C relate to long-term health outcomes in diabetic patients. Why is maintaining an A1C below 7% crucial for preventing diabetes complications.

The Significance of A1C in Diabetes Management

A1C, also known as glycated hemoglobin, is a crucial metric in diabetes management. It provides a comprehensive view of blood glucose control over the past 2-3 months. But why is this measurement so important, and what constitutes a “good” A1C level?

A target A1C of less than 7% has been established as the benchmark for good diabetes control. This recommendation is based on extensive research demonstrating the relationship between A1C levels and the risk of diabetes-related complications.

What exactly is A1C?

A1C is a blood test that measures the percentage of hemoglobin proteins in red blood cells that are coated with glucose. Since red blood cells typically live for about three months, this test provides an average of blood glucose levels over that period.

The Diabetes Control and Complications Trial (DCCT): A Landmark Study

The Diabetes Control and Complications Trial (DCCT), conducted from 1982 to 1993, was a pivotal study that revolutionized our understanding of diabetes management. This extensive research involved 1,441 volunteers aged 13 to 39, all with type 1 diabetes.

Study Design and Findings

Participants were randomly assigned to two groups:

• Conventional therapy group: Received about two insulin injections daily
• Intensive therapy group: Received either multiple daily insulin injections (MDI) or used an insulin pump

The results were striking:

• Conventional therapy group: Average A1C of 9.1%
• Intensive therapy group: Average A1C of 7.2%

These findings definitively demonstrated the importance of tight blood sugar control in preventing diabetes complications.

Impact of Intensive Therapy on Diabetes Complications

The DCCT revealed significant reductions in diabetes-related complications for those in the intensive therapy group:

Eye Disease (Retinopathy)

• 76% overall reduction in development
• 54% less progression in those with existing retinopathy
• 45% lower risk of requiring laser therapy

Kidney Disease (Nephropathy)

• 34% reduction in microalbuminuria
• 56% reduction in proteinuria

Nerve Disease (Neuropathy)

• 69% reduction in occurrence for those without initial complications
• 57% reduction in occurrence for those with some initial complications

Heart Disease

A trend towards reduction in risk factors was observed in both groups.

Translating DCCT Results to Personal Diabetes Management

For individuals with type 1 diabetes, the DCCT results offer compelling evidence for maintaining tight glucose control. Each 1% reduction in A1C translates to a 45% lower risk of developing chronic diabetes complications. This significant benefit emphasizes the importance of striving for an A1C as close to normal (<6%) as safely possible.

Even for those who already show signs of chronic complications, maintaining an A1C below 7% can help stabilize conditions such as kidney and eye disease for years.

The EDIC Study: Long-Term Benefits of Intensive Therapy

Following the DCCT, the Epidemiology of Diabetes Interventions & Complications (EDIC) study continued to follow the original participants. This long-term follow-up revealed surprising and encouraging results:

• Both groups eventually stabilized at an average A1C of 8%
• Despite this, the benefits of the original intensive therapy persisted
• For the first time, clear benefits in reducing heart and cardiovascular disease were demonstrated

EDIC Results (1993-2005)

Comparing the original intensive and conventional therapy groups after 11 years of follow-up:

• Eyes (retinopathy): 75% less progression
• Kidney: 86% risk reduction in onset of new microalbuminuria
• Heart/Cardiovascular: 57% less risk of heart attack, stroke, or CV death

These findings underscore the long-term benefits of early and optimal blood glucose control, even if tight control is not maintained indefinitely.

Beyond A1C: A Holistic Approach to Diabetes Management

While A1C is a crucial metric in diabetes management, it’s important to recognize that it’s not the only factor to consider. A comprehensive approach to diabetes care involves several other elements:

Blood Pressure Control

Maintaining healthy blood pressure levels is vital for reducing the risk of cardiovascular complications in diabetes. The American Diabetes Association recommends a target blood pressure of less than 140/90 mmHg for most adults with diabetes.

Lipid Management

Managing cholesterol and triglyceride levels is crucial for heart health in diabetic patients. Regular lipid panel tests and appropriate interventions, including lifestyle changes and medication when necessary, are essential components of diabetes care.

Regular Physical Activity

Exercise plays a significant role in managing blood glucose levels and improving overall health. The ADA recommends at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, spread over at least three days.

Healthy Diet

A balanced, nutritious diet is fundamental to diabetes management. This typically involves monitoring carbohydrate intake, choosing foods with a low glycemic index, and maintaining a healthy balance of proteins, fats, and fiber.

Regular Monitoring

While A1C provides a long-term view of glucose control, daily blood glucose monitoring is essential for making informed decisions about medication, diet, and activity. The frequency of monitoring may vary based on individual needs and treatment plans.

Personalized A1C Goals: Tailoring Targets to Individual Needs

While an A1C below 7% is generally considered optimal, it’s important to recognize that this target may not be appropriate or achievable for everyone. Factors that may influence individual A1C goals include:

• Age and life expectancy
• Duration of diabetes
• Presence of other health conditions
• Risk of severe hypoglycemia
• Individual preferences and quality of life considerations

Healthcare providers may recommend higher A1C targets for certain individuals, particularly older adults or those with multiple comorbidities, to balance the benefits of tight glucose control with the risks of hypoglycemia and other adverse events.

Individualized Care Plans

The development of personalized diabetes management plans, including A1C targets, should involve a collaborative discussion between the patient and their healthcare team. This approach ensures that treatment goals align with the individual’s overall health status, lifestyle, and personal preferences.

Emerging Technologies and Their Impact on A1C Management

Advancements in diabetes technology are providing new tools to help individuals achieve and maintain optimal A1C levels:

Continuous Glucose Monitoring (CGM)

CGM systems provide real-time glucose readings throughout the day and night, allowing for more precise insulin dosing and earlier detection of glucose trends. Studies have shown that CGM use can lead to improvements in A1C levels and reduced time spent in hypoglycemia.

Automated Insulin Delivery Systems

Also known as “artificial pancreas” systems, these devices combine CGM technology with insulin pumps to automatically adjust insulin delivery based on glucose levels. Early studies suggest that these systems can help improve A1C levels and reduce the burden of diabetes management.

Digital Health Apps

Smartphone apps and other digital tools can help individuals track their glucose levels, medication, diet, and exercise, providing valuable insights and reminders to support optimal diabetes management.

While these technologies offer promising avenues for improving A1C control, it’s important to note that they are not a substitute for comprehensive diabetes education and regular medical care. The most effective approach to diabetes management typically involves a combination of technology, education, and personalized care plans.

The Psychological Aspect of A1C Management

Achieving and maintaining optimal A1C levels requires more than just medical interventions; it also involves addressing the psychological and emotional aspects of living with diabetes.

Diabetes Distress

Many individuals with diabetes experience diabetes distress, a condition characterized by feelings of overwhelm, frustration, or burnout related to managing their condition. This emotional state can impact adherence to treatment plans and, consequently, A1C levels.

Strategies for Emotional Well-being

• Seek support from diabetes educators, mental health professionals, or support groups
• Practice stress-reduction techniques such as mindfulness or meditation
• Set realistic, achievable goals to avoid feelings of failure or inadequacy
• Celebrate small victories in diabetes management

Addressing the emotional aspects of diabetes can lead to improved self-care behaviors and, ultimately, better A1C control.

Future Directions in A1C Research and Management

As our understanding of diabetes continues to evolve, researchers are exploring new avenues for improving A1C management and overall diabetes care:

Precision Medicine

The field of precision medicine aims to tailor diabetes treatment based on individual genetic, environmental, and lifestyle factors. This approach could lead to more personalized A1C targets and treatment strategies.

Novel Therapies

Ongoing research is exploring new medications and treatment approaches that may offer improved glucose control with fewer side effects. These advancements could make it easier for individuals to achieve and maintain optimal A1C levels.

Improved Monitoring Technologies

Future developments in glucose monitoring technology may provide even more accurate and convenient ways to track blood glucose levels and predict A1C trends.

As these areas of research progress, individuals with diabetes can look forward to increasingly sophisticated and personalized approaches to A1C management.

The Global Impact of Improved A1C Management

The emphasis on maintaining good A1C levels has implications that extend beyond individual health outcomes. On a broader scale, improved diabetes management can have significant societal and economic impacts:

Reduced Healthcare Costs

By preventing or delaying the onset of diabetes-related complications, maintaining optimal A1C levels can lead to substantial reductions in healthcare expenditures. This is particularly important given the rising global prevalence of diabetes and its associated economic burden.

Improved Quality of Life

Better A1C control translates to fewer complications and hospitalizations, allowing individuals with diabetes to lead fuller, more active lives. This can have positive ripple effects on families, communities, and workplaces.

Advancing Public Health

As more individuals achieve better A1C control, the overall health of populations improves. This can lead to increased productivity, reduced disability rates, and a decreased burden on healthcare systems.

The global focus on A1C management underscores the importance of diabetes education, access to care, and ongoing research in improving outcomes for individuals and societies affected by this chronic condition.

Conclusion: The Ongoing Journey of A1C Management

Understanding and maintaining optimal A1C levels is a cornerstone of effective diabetes management. The wealth of research, from the groundbreaking DCCT study to ongoing investigations, consistently underscores the importance of striving for an A1C below 7% for most individuals with diabetes.

However, it’s crucial to remember that A1C is just one part of a comprehensive diabetes care plan. Personalized goals, consideration of individual circumstances, and attention to overall health and well-being are equally important. As technology advances and our understanding of diabetes deepens, the tools and strategies for achieving optimal A1C levels will continue to evolve.

For individuals living with diabetes, the journey towards optimal A1C control is ongoing. It requires dedication, support, and a partnership with healthcare providers. But with each step towards better control, the risk of complications decreases, and the potential for a healthier, fuller life increases.

As we look to the future, the focus on A1C management will likely remain central to diabetes care. However, this focus will be increasingly integrated with personalized approaches, advanced technologies, and a holistic view of health. The goal remains clear: to empower individuals with diabetes to achieve their best possible health outcomes, with A1C serving as a valuable guide along the way.

Why should my A1C be 7 per cent or less? —

Over the last several years a significant amount of research has proven that control matters, and good control is now defined as an A1C of < 7 per cent.

What is an A1C?

An A1C test shows your blood glucose control over the last 2 or 3 months.

Diabetes Control & Complications Trial (DCCT) 1982-1993

Research from both the Diabetes Control & Complications Trial (DCCT) and its follow up study (EDIC) proves that having an A1C of 7 per cent is definitely worthwhile for persons with type 1 diabetes.

Exactly 1441 volunteers aged 13 to 39, all with type 1 diabetes, took part. These people agreed to randomly be assigned to either conventional treatment – taking about two insulin injections a day – or to intensive treatment (IT) – taking either multiple dose insulin (MDI, about 4 injections a day) or an insulin pump.

During the study the A1C of each group was compared:

• 
  the conventional therapy group had an average A1C of 9. 1 per cent (normal 4-6 per cent)
• 
  the intensive therapy group had an average A1C of 7.2 per cent

The purpose was to finally demonstrate whether or not good blood sugar control was really important to prevent the complications of diabetes. And indeed it is – as you can see below, complications developed at a much lower rate in the intensively treated group compared to the conventional group.

The reduction in risk for eye disease (the primary outcome) was so great that the study was stopped early – and intensive therapy to achieve an A1C of 7 per cent or less became the standard of practice worldwide!

But what do these results mean for you?

For you, a person with type 1 diabetes, lowering your A1C by 1 per cent means a 45 per cent less risk you will develop the chronic complications of diabetes! That’s 45 per cent for each 1 per cent lower! The closer to normal (<6 per cent) the A1C is the better!

The results also mean that an A1C of <7 per cent will also be good for you if you already have some signs of chronic complications. For example, kidney and eye disease may stay stable for years!

At the end of the original DCCT trial, all the people in the conventional group changed to intensive therapy and their A1C lowered. Then both groups went back to their usual diabetes care teams, coming back to the study centre for a once yearly assessment.

This same group of volunteers has remained in the DCCT follow up study called Epidemiology of Diabetes Interventions & Complications (EDIC) since 1993. Now that’s commitment to a research study!

Over time the A1C of the original intensive therapy and the former conventional therapy groups evened out at an average of 8%, but the benefits of intensive therapy remained – much to everyone’s surprise. And for the first time, the benefits of good control on heart/cardiovascular disease were clearly shown.

 

 

DCCT/EDIC Results 1993-2005 (NEJM 2005)

Original Intensive vs. Conventional Therapy Groups: Comparison of Complications Status	EDIC 11 yrs of A1C~ 8% Both testing 4 x per day
Eyes (retinopathy)	75% less progression
Kidney	86% risk reduction in onset of new microalbuminuria
Heart/ Cardiovascular	57% less risk of heart attack (MI), stroke or CV death Intensive group: 31 people with 46 events Conventional group: 52 people with 98 events

  

The latest results (2005) continue to support the earliest possible adoption of intensive therapy to achieve an A1C of <7 per cent. Early and optimal blood glucose control has long term benefits.

That’s why we believe so passionately in using the IT system, and why we want to help you find the best way for you to do this. We know it isn’t easy to act like a pancreas day in and day out. It‘s hard work – and we want to help!

Rethinking A1c goals for type 2 diabetes

“Treat the patient, not the number.” This is a very old and sound medical school teaching. However, when it comes to blood sugar control in diabetes, we have tended to treat the number, thinking that a lower number would equal better health.

Uncontrolled type 2 diabetes (also known as adult-onset diabetes) is associated with all sorts of very bad things: infections, angry nerve endings causing chronic pain, damaged kidneys, vision loss and blindness, blocked arteries causing heart attacks, strokes, and amputations… So of course, it made good sense that the lower the blood sugar, the lower the chances of bad things happening to our patients.

Tracking blood sugar control over time

One easy, accurate way for us to measure a person’s blood sugar over time is the hemoglobin A1c (HbA1c) level, which is basically the amount of sugar stuck to the hemoglobin molecules inside of our blood cells. These cells last for about three months, so, the A1c is thought of as a measure of blood sugars over the prior three months.

Generally, clinical guidelines have recommended an A1c goal of less than 7% for most people (not necessarily including the elderly or very ill), with a lower goal — closer to normal, or under 6.5% — for younger people.

We as doctors were supposed to first encourage diet and exercise, all that good lifestyle change stuff, which is very well studied and shown to decrease blood sugars significantly. But if patients didn’t meet those target A1c levels with diet and exercise alone, then per standard guidelines, the next step was to add medications, starting with pills. If the levels still weren’t at goal, then it was time to start insulin injections.

While all this sounds very orderly and clinically rational, in practice it hasn’t worked very well. I have seen firsthand how enthusiastic attention to the A1c can be helpful as well as harmful for patients.

And so have experts from the Clinical Guidelines Committee of the American College of Physicians, a well-established academic medical organization. They examined findings from four large diabetes studies that included almost 30,000 people, and made four very important (and welcome!) new guidelines around blood sugar control. Here’s the big picture.

Doctors and patients should discuss goals of treatment together and come up with an individual plan

Blood sugar goals should take into account a patient’s life expectancy and general health, as well as personal preferences, and include a frank discussion of the risks, benefits, and costs of medications. This is a big deal because it reflects a change in how we think about blood sugar control. It’s not a simply number to aim for; it’s a discussion. Diabetes medications have many potential side effects, including dangerously low blood sugar (hypoglycemia) and weight gain (insulin can cause substantial weight gain). Yes, uncontrolled blood sugars can lead to very bad things, but patients should get all the information they need to balance the risks and benefits of any blood sugar control plan.

An A1c goal of between 7% and 8% is reasonable and beneficial for most patients with type 2 diabetes…

…though if lifestyle changes can get that number lower, then go for it. For patients who want to live a long and healthy life and try to avoid the complications of diabetes, they will need to keep their blood sugars as normal as possible — that means an A1c under 6.5%. However, studies show that using medications to achieve that goal significantly increases the risk of harmful side effects like hypoglycemia and weight gain. To live longer and healthier and avoid both the complications of diabetes as well as the risks of medications, there’s this amazing thing called lifestyle change. This involves exercise, healthy diet, weight loss, and not smoking. It is very effective. Lifestyle change also can help achieve healthy blood pressure and cholesterol levels, which in turn reduce the risk for heart disease. And heart disease is a serious and common complication of diabetes.

Lifestyle change should be the cornerstone of treatment for type 2 diabetes. The recommendations go on to say that for patients who achieve an A1c below 6.5% with medications, we should decrease or even discontinue those drugs. Doing so requires careful monitoring to ensure that the person stays at the goal set with his or her doctor, which should be no lower than 7%, for the reasons stated above.

We don’t even need to follow the A1c for some patients

Elderly patients, and those with serious medical conditions, will benefit from simply controlling the symptoms they have from high blood sugars, like frequent urination and incontinence, rather than aiming for any particular A1c level. Who would be included in this group? People with a life expectancy of less than 10 years, or those who have advanced forms of dementia, emphysema, or cancer; or end-stage kidney, liver, or heart failure. There is little to no evidence for any meaningful benefit of intervening to achieve a target A1c in these populations; there is plenty of evidence for harm. In particular, diabetes medications can cause low blood sugars, leading to weakness, dizziness, and falls. There is the added consideration that elderly and sick patients often end up on a long list of medications that can (and do) interact, causing even more side effects.

The bottom line

There is no question that type 2 diabetes needs to be taken seriously and treated. But common sense should rule the day. Lifestyle changes are very effective, and the side effects of eating more healthfully and staying more active are positive ones. Every person with type 2 diabetes is an individual. No single goal is right for everyone, and each patient should have a say in how to manage their blood sugars and manage risk. That means an informed discussion, and thoughtful consideration to the number.

What is glycated hemoglobin, what does it mean in a blood test and what is its norm

Many people do not know why glycated hemoglobin is donated. In fact, this is an important indicator with which you can track the development of diabetes. According to this coefficient, it is easy to detect the disease at the earliest stages, and begin treatment.

What does glycated hemoglobin mean?

Often, even people with diabetes do not know what glycated hemoglobin is. Everything is very simple. When a person consumes carbohydrates, sugars enter the bloodstream. They pass through the erythrocyte membrane. Their amino acids react with sugars to form glycated hemoglobin. The compound is very stable, its concentration persists for 120 days, after which the red blood cells are destroyed.

All people have glycated hemoglobin. The difference between healthy and diabetic people is only in its concentration. This indicator displays how correctly carbohydrate metabolism processes are going on in the body. If there are failures and the sugar level is elevated, then the indicator will be more than normal.

These figures can be used to detect latent diabetes, because the parameter displays the sugar level not at a specific moment when it is easy to lower it, but for 3 months. It is important during treatment, to monitor the patient’s condition.

Therefore, what is glycated hemoglobin in a blood test, every person should know, especially those who are already at risk or have diabetes.

How to donate blood for glycated hemoglobin?

The glycated hemoglobin test does not require any specific preparation. It is taken in the morning, blood is taken from a vein. Thyroid disease, systematic intake of vitamins, anemia can affect the results.

Eaten food does not distort the result, just like alcohol, stress the day before, SARS and influenza.

What is the norm of glycated hemoglobin?

In order not to worsen your condition, you need to know not only what glycated hemoglobin in the blood means, but also to know your norm.

The indicator depends on age:

1. For teenagers and people under 30 years old, an indicator that does not exceed 6.5% is considered the norm.
2. In middle age (from 30 to 50 years old), the parameter should not exceed 7%.
3. For the elderly who are over 60 years old, an increase of up to 7.5% is acceptable, but no more.

In a healthy child, the indicator is the same as in adults. Its normal range is from 4.5 to 6%. If deviations from these norms are found, it is necessary to undergo an additional examination to determine why the blood sugar level is elevated. Usually, with indicators of 6.1-6.4% (doctors call this condition prediabetes), health control needs to be strengthened.

If there is no suspicion of diabetes, then it is enough to undergo such a test once every 2-3 years. If the indicator is fixed at an elevated level, this means that the test must be carried out every year. Depending on the progression of the disease, a doctor may recommend that a patient with diabetes be tested every 3 or 6 months.

What is the norm for diabetics?

For physicians, the glycated hemoglobin value can tell a lot. Determination of its level provides more thorough control of sugar and correction of the diet, treatment regimen, dosage of drugs. For those diagnosed with diabetes, levels of less than 8% are normal. A parameter that is higher than this value indicates the possibility of serious complications. But you can’t lower it too sharply, it will only get worse, because. the body is already accustomed to a high concentration of glucose.

At a young age, you should strive to keep it within 6.5-7%, on average from 7 to 7.5%, after 50 make sure that the figure is not higher than 7.5-8%.

How to reduce the level of glycated hemoglobin?

It should be remembered that glycated hemoglobin determines to bring these numbers back to normal. It shows the average glucose level over 3 months, not at a specific point in time. Therefore, this indicator at home can be reduced only by reducing excess weight and improving metabolism.

And for this you need:

1. Eat right. The diet should be less fatty and fried foods. The dosage of fresh fruits and vegetables should be increased. Legumes, bananas, low-fat dairy products, lean fish, nuts are useful.
2. Go in for sports. Physical activity should be at least 30 minutes a day. This optimizes weight, and protects the heart from developing complications.
3. Manage stress. Any shocks negatively affect the metabolism and the heart. Therefore, stress must be dealt with with the help of breathing exercises, meditation.

Knowing what glycated hemoglobin shows in a blood test, you can monitor your health and well-being. This applies to both healthy people and diabetics.

HOW TO LOWER GLYCATED HEMOGLOBIN – Healsens Digital Preventive Care

Diabetes is a major health problem worldwide and its prevalence is increasing significantly. In turn, an analysis of glycated hemoglobin (A1C) will help you find out how your body copes with sugar. For many, this is an opportunity to prevent a disease or diagnose it at an early stage. After all, the disease does not develop at lightning speed! For us, this is an opportunity to catch a state when the body does not function normally, but has not yet become ill. We are talking about prediabetes. But for people with diabetes, this test is also useful. Mainly because it shows the risks of complications. In this article, we will talk about the situation when the test has already been passed, and its results were outside the healthy range. In addition, we will analyze an integrated approach to the problem, what necessary actions it includes and why it is impossible to do without changing your lifestyle. But let’s go in order. After all, in order to answer the question of how reduce glycated hemoglobin , you need to consider the problem carefully.

Speaking of normal hemoglobin A1c levels, let’s remember these ranges. For example, for people without diabetes, the healthy range is 4% to 5.6% . If your hemoglobin A1c is between 5.7% and 6.4% , that means you already have prediabetes. Levels 6.5% speak of diabetes.

Targets and Treatments

In the US, 79 million adults have prediabetes and its prevalence is 3 times that of diabetes. And if prediabetes is considered a reversible disease, then diabetes is not yet curable. It is also important to understand that treating diabetes does not prevent all of its complications. That is why prevention is so important.

How to Lower Glycated Hemoglobin Without Pills

In 2002, Knowler et al hypothesized that lifestyle interventions could prevent or delay the development of diabetes. The researchers randomly assigned patients with prediabetes. Some of them were offered a placebo, others were included in a special lifestyle change program. The goal of this program was to increase physical activity of at least 150 minutes per week and reduce weight by at least 7%. The average age of the participants was 51 years and the BMI was 34.0 kg/m2. The mean follow-up period was 2.8 years. As a result, lifestyle intervention reduced morbidity by 58% compared to placebo ¹ .

Further analysis of this study showed that if people did not change their lifestyle, the majority developed type 2 diabetes within the next 10 years.

Since then, numerous studies have confirmed these findings. So, in 2013, researchers compared the effectiveness of lifestyle interventions with standard treatment. Seven of 9 studies reported that lifestyle changes reduced the risk of developing diabetes up to 10 years after lifestyle intervention ² .

However, for some people with prediabetes, lifestyle changes are not enough.

Medication approach to prevent diabetes

Evidence for the potential benefit of pharmacotherapy to prevent diabetes in prediabetic patients was published in 2002.

Researchers have shown that drugs such as metformin reduce the incidence of diabetes. On the other hand, this decrease is not as strong as with lifestyle changes. However, metformin also has a beneficial effect on BMI and lipid concentrations.

In 2010, Lilly and Godwin, after a systematic literature review and meta-analysis, concluded that metformin reduces the risk of developing diabetes by 45% ³ .

Healsens story on glycated hemoglobin

Finally, metformin is currently the only drug recommended by the ADA for the treatment of prediabetes. According to the ADA, it is commonly prescribed for patients at high risk of developing diabetes. It is worth noting that if people fail lifestyle therapy and their glucose levels rise, metformin is a reasonable second choice.

However, despite the widespread use of metformin, the drug is not suitable for everyone. So, to lower glycated hemoglobin, ACE/AACE recommends a two-pronged approach. First, intensive intervention in lifestyle. Namely, an increase in physical activity, walking at least 150 minutes a week. As well as weight loss by 7% if BMI exceeds 25 kg/m2 ⁴ . Secondly, prevention of complications of cardiovascular diseases. In this case, drugs may be prescribed to treat high blood pressure and cholesterol.

Fiber to lower glycated hemoglobin

Increasing dietary fiber is associated with reduced glycated hemoglobin (HbA1c), improved lipid profile and weight loss ⁵ . This is because the increased fiber content lowers the glycemic index of foods.

In addition, foods containing dietary fiber are also rich sources of magnesium . We emphasize that magnesium is a co-factor for enzymes involved in glucose metabolism. In turn, dietary magnesium reduces the incidence of type 2 diabetes. Research also suggests that the association of dietary fiber with a reduced risk of diabetes may be partly explained by markers of inflammation. We are talking about markers such as interleukin-6 and tumor necrosis factor α ⁶ .

Finally, several studies have shown that when all dietary fibers were divided into grain, fruit and vegetable fibers, it turned out that grain fibers most reduced the incidence of type 2 diabetes ⁷ .
