How Eating Fermented Foods Can Help Reverse Diabetes

Fermented foods have been a staple in diets for centuries. They were used to keep food fresh, make it taste better, and get rid of toxins. Now, studies show they might help manage and even reverse diabetes. In places like South East- and Far East-Asia, fermented foods are a big part of the diet because of their health benefits and cultural importance. In the West, their use has dropped with the invention of refrigeration¹.

Scientists are looking into how fermented foods affect blood sugar and type 2 diabetes risk. A study from Stanford University in July 2021 found that these foods boost the diversity of gut bacteria and cut down on inflammation. This is good news for diabetes prevention². Another review from December 2020 pointed out that traditional fermented foods can help treat diabetes. They do this by improving how well sugar is controlled, helping with weight, and boosting antioxidants².

Fermented foods are full of good microbes that can make gut health better and lessen linked to diabetes. Making these foods involves micro-organisms turning sugars and starch into alcohol and acids. This helps good bacteria, called probiotics, grow¹. These probiotics can lower blood sugar and make insulin work better. So, fermented foods could be a big help in managing diabetes.

Even though some studies look promising, we can’t say for sure yet how much fermented foods can help with diabetes. Experts suggest eating foods like kimchi, sauerkraut, yogurt, kefir, kombucha, and tempeh for their health benefits and potential to fight diabetes². While they might not right away help with diabetes, they could be good for your health in the long run by making your gut stronger and lowering inflammation².

The History and Science of Fermented Foods

Fermented foods have been a key part of our diets for thousands of years. They help preserve food and add flavor³. Cheesemaking started around 8000 BCE, and alcohol fermentation dates back to 7000 – 6600 BCE⁴. These methods have made foods last longer, making them more available and nutritious³.

Origins of Fermentation in Food Preservation

Fermentation was easy to do and needed little resources, making it a great way to keep food fresh³. The Egyptians made the first leavened bread around 4000-3500 BCE⁴. Fermented foods like dairy and vegetables became part of our history⁴. But in the 20th century, fermented foods became less common in the US diet³.

Microbes Involved in the Fermentation Process

Until 1857, the science of fermentation was a mystery. Louis Pasteur showed that microbes cause fermentation⁴. Microbes like bacteria and yeasts change food compounds into new substances. This can make food taste better and be more nutritious. Lactic acid bacteria ferment veggies like sauerkraut, while yeast makes wine, beer, and bread rise⁴.

Fermentation Type	Microbes Involved	Examples of Fermented Foods
Lactic Acid Fermentation	Lactic Acid Bacteria	Sauerkraut, Kimchi, Yogurt
Alcoholic Fermentation	Yeast (Saccharomyces)	Wine, Beer, Sourdough Bread
Acetic Acid Fermentation	Acetobacter	Vinegar, Kombucha

Microbes are key to biodiversity and affect our health and agriculture. Knowing about them helps us build a healthy gut³. The microbes in different places can change the taste of fermented foods, showing how unique they are³. As people get more interested in fermentation, it’s important to understand its science and health benefits³⁴⁵.

Fermented Foods and the Microbiome

The human gut is a complex place, filled with many microorganisms. These microorganisms, known as the gut microbiome, are vital for our health and well-being⁶. They outnumber our human cells by a lot and have a huge genome compared to ours⁶. Fermented foods can change the gut microbiome, making it healthier and lowering the risk of diseases like diabetes.

Impact of Fermented Foods on Gut Bacteria Diversity

Fermented foods have been around for thousands of years, found in many traditional diets⁷. A study with 36 healthy adults showed that eating fermented foods like yogurt and kimchi made their gut microbiome more diverse⁸. This was especially true for those eating more of these foods⁸. In contrast, a high-fiber diet didn’t have the same effect⁸.

There’s a wide variety of fermented foods worldwide, showing the importance of understanding their impact on health⁷. Adding different fermented foods to your diet can help support good gut bacteria and increase microbiome diversity.

Short-Chain Fatty Acids and Their Role in Metabolism

Fermented foods can help by supporting gut bacteria that make short-chain fatty acids (SCFAs)⁸. These acids are made when certain bacteria break down fibers and starches. SCFAs help control blood sugar levels and release insulin.

Eating more whole grains, fruits, vegetables, and legumes can make the gut microbiome more diverse⁶. This is because these foods support SCFA-producing bacteria. Fermented foods can help grow these beneficial bacteria, improving insulin sensitivity and blood sugar control.

SCFAs also have many other health benefits, like reducing inflammation and strengthening the gut⁸. As we learn more about fermented foods, the gut microbiome, and SCFAs, adding these foods to our diet could be a great way to stay healthy.

Animal Studies on Fermented Foods and Diabetes

Animal studies have shown that fermented foods could help manage diabetes and lower blood sugar. For example, mice fed kombucha, a fermented tea, had lower blood sugar levels⁹. This drink contains bacteria like Komagataeibacter xylinus and Lactobacillus plantarum.

Rats with diabetes ate fermented Cordyceps sinensis fungus and had lower blood sugar. Another study found that diabetic rats eating fermented grain had lower blood sugar too. Mice with type 2 diabetes eating fermented noni fruit had lower blood sugar and better insulin sensitivity.

“Many animal studies indicate that fermented foods improve blood sugar control in diabetic subjects, but human studies are needed to confirm these findings and determine the optimal types and amounts of fermented foods for diabetes management.”

About 462 million people worldwide have type 2 diabetes, making up 6.28% of the population in 2017¹⁰. The World Health Organization says 5.4% of people globally will have T2DM by 2025⁹.

Studies suggest that an imbalance in gut bacteria, or dysbiosis, is linked to type 2 diabetes⁹. Fermented drinks like kombucha, kefir, and enzymes could help manage diabetes⁹.

These animal studies look promising for fermented foods in diabetes care. But, we need more human studies to confirm these results. We also need to figure out the best fermented foods and amounts for people with diabetes.

Human Studies: Fermented Foods and Blood Sugar Control

Animal studies show that fermented foods might help manage diabetes. But, we need human studies to see how they work in real life. Researchers are looking at foods like kimchi and kefir to see how they affect glucose levels in people with prediabetes and type 2 diabetes.

Kimchi and Prediabetes

Kimchi, a Korean fermented veggie dish, might help control blood sugar in people with prediabetes. A study with 21 people found that eating fermented kimchi improved glucose levels more than eating fresh kimchi¹¹. This shows that kimchi’s fermentation and its probiotics could help fight diabetes.

Kefir and Type 2 Diabetes

Kefir, a fermented milk drink, could help manage type 2 diabetes. A trial with 60 type 2 diabetes patients compared kefir with regular fermented milk. After 8 weeks, the kefir group had lower blood sugar levels¹².

The kefir had special probiotics, unlike the control milk. This suggests that these probiotics helped improve glucose levels¹². The study suggests kefir could be a good addition to diabetes treatment.

Regular eating of fermented dairy, like yogurt, was linked to a 7.5% lower diabetes risk. Yogurt was even more effective, reducing risk by 17.2%¹².

A big study found that eating fermented foods lowered fasting blood glucose by 0.43 mg/dL (0.02 mmol/L)¹². These foods also made insulin resistance and cholesterol levels go down¹².

These studies are promising for fermented foods and blood sugar control. But, we need more research to know how much of these foods is best for people with diabetes or at risk of it¹².

The Potential of Yogurt in Diabetes Prevention

Yogurt is a fermented dairy product that could help prevent type 2 diabetes. It’s packed with billions of good bacteria, making it a great source of probiotics¹³. Yogurt contains Streptococcus thermophilus and Lactobacillus bulgaricus, which give it a unique taste and texture¹³.

Studies have looked into how yogurt might lower diabetes risk. One study found that eating 80g of yogurt daily could lower diabetes risk by 14%¹³. But not all studies agree. Another study with 59,000 Black women found no link between yogurt and type 2 diabetes¹³.

Even with some good signs, yogurt hasn’t been proven to directly help with insulin or blood sugar levels¹³. Yet, some research suggests that probiotics in yogurt could improve glucose and lipid metabolism in people with type 2 diabetes¹⁴. We need more studies to understand how yogurt affects these levels.

“While yogurt shows promise in diabetes prevention, its potential effects could stem from a combination of healthy fats, protein, calcium, and probiotics, rather than probiotics alone.”

Now, type 2 diabetes affects about 11.4% of people in the U.S¹³. Being overweight or obese increases the risk of getting diabetes. So, finding good foods to prevent diabetes is key¹⁴. Yogurt, with its 8 grams of protein per 100g, could be a good choice for a diet that helps manage diabetes¹³.

Yogurt might be helpful in preventing diabetes, but we need more research to be sure. We should focus on standardizing yogurt products and doing bigger, longer studies to get clear evidence¹⁴. Always check how yogurt affects your blood sugar and talk to a doctor before changing your diet for diabetes.

Mechanisms Behind Fermented Foods’ Antidiabetic Effects

Fermented foods are being studied for their potential to help manage blood sugar levels. They contain special bacteria and substances that might improve how the body uses insulin and absorbs sugar. This could lead to better sugar control.

Enhancing Insulin Sensitivity

Calcium in fermented dairy products might help control blood sugar, research says¹⁵. Foods like kefir could make the gut work better and help insulin do its job¹⁵.

Short-chain fatty acids from fermentation can also help. These acids can change the gut’s bacteria, reduce inflammation, and lower hunger hormones¹⁵. They can make the gut healthier, which might make insulin work better¹⁵.

Blocking Carbohydrate-Digesting Enzymes

Probiotics in fermented foods might slow down the digestion of carbs. This means less sugar gets into the bloodstream, which can help control blood sugar spikes.

A study on mice with diabetes showed that fermented food paste helped lower blood sugar and improve insulin use¹⁶. The mice eating this paste had better insulin levels and were less inflamed¹⁶.

This research points to fermented foods as a possible way to manage diabetes. Adding these foods to a diet could help control blood sugar and prevent diabetes type 2.

Incorporating Fermented Foods in a Diabetes-Friendly Diet

The number of people with type-2 diabetes is rising, with the UK now having five million cases¹⁷. It’s important to look at diets that can help manage this condition. Fermented foods can support gut health and help control blood sugar levels.

The fermented food market is set to grow by $533 million soon¹⁷. This shows more people see the health benefits of these foods. Eating fermented foods like kimchi can help manage diabetes¹⁸. A study found that fermented kimchi helped improve blood sugar levels in people with pre-diabetes more than fresh kimchi¹⁷.

Choosing Probiotic-Rich Fermented Foods

When picking fermented foods for your diet, choose tangy and spicy ones like kimchi and plain yogurt. These foods are good for gut health and may help control blood sugar. Studies show probiotics can help people with type 2 diabetes¹⁸.

Other fermented foods high in probiotics you might want to add to your diet include:

Kefir
Sauerkraut
Tempeh
Miso
Kombucha

Monitoring Blood Sugar Response to Fermented Foods

Fermented foods are nutritious and can be good for a diabetes-friendly diet. But, their effects on diabetes need more study. It’s key to watch your blood sugar to see how different fermented foods affect you.

Keep a food diary and note your blood sugar before and after eating fermented foods. This can show you which ones are best for your diabetes care.

Adding probiotic-rich fermented foods to your diet and watching your blood sugar can help your gut health and diabetes care. Always talk to your healthcare provider before changing your diet or diabetes treatment.

Probiotic Strains Associated with Metabolic Improvements

Some probiotic strains help improve blood sugar balance and metabolic health. Lactobacillus species like L. acidophilus and Bifidobacterium strains such as B. breve have shown promise in managing type 2 diabetes¹⁹²⁰. Streptococcus thermophilus also helps with metabolic health¹⁹.

A study looked at 32 randomized trials and found probiotics helped lower cholesterol, triglycerides, and blood pressure in people with type 2 diabetes¹⁹. They also raised HDL levels but didn’t affect BMI or LDL levels¹⁹.

Animal studies show probiotics can improve insulin resistance and metabolism. For example, Bifidobacterium breve helped reduce weight and improve metabolism²⁰.

But, different foods have different probiotics. Some studies show probiotics help with insulin resistance, but more research is needed to know which ones work best for blood sugar control²⁰.

Probiotic Strain	Potential Benefits
L. acidophilus	Improved blood sugar balance and metabolic health
B. lactis	Enhanced insulin sensitivity and glucose metabolism
L. casei	Reduced inflammation and improved lipid profiles
L. rhamnosus	Improved glycemic control and reduced oxidative stress
B. breve	Promoted less weight gain and improved glucose metabolism

Diabetes is becoming more common, with predictions of 10.4% of people having it by 2040¹⁹. By 2045, the number of people with diabetes could hit 700 million²⁰. Probiotics, especially strains like L. acidophilus and B. lactis, could help manage metabolic health. Adding probiotic-rich foods or supplements might support blood sugar balance and overall health.

Fermented Soy Products and Diabetes Management

Fermented soy products like tempeh and miso are being studied for their role in diabetes management. These foods have a long history in Asia, over 10,000 years. They are made by fermenting soybeans with microorganisms such as Bacillus spp., Lactobacillus spp., and Aspergillus spp²¹.

Studies show that eating fermented soy foods can lower the risk and severity of diabetes. A big study looked at 1,660,304 people and found that eating soybeans can cut the risk of Type 2 diabetes and heart disease²². The good stuff in soy, like isoflavones and unsaturated fats, helps prevent Type 2 diabetes, heart diseases, and stroke²².

These soy products can slow down diabetes and make it less severe by working on different body parts²¹. Animal tests show that fermented soy milk with herbs can lower blood sugar and make insulin work better in diabetic mice. Also, a mix of fermented soybeans and rice bran helped improve glucose levels in animals.

The benefits of fermented soy come from several sources. Soy protein peptides, lecithin, and isoflavones can better lipid profiles and help with lipid metabolism²². Isoflavones also help with glucose transporter 4 (GLUT4) and AMP-activated protein kinase (AMPK) phosphorylation, lowering the risk of heart disease and diabetes²². Plus, these foods have anti-hyperglycemic effects and support gut health with their probiotics²¹.

Adding fermented soy to a diet for diabetes is smart. Choose ones full of probiotics and watch your blood sugar. Tempeh, a high-protein fermented soy option, is great for people with diabetes who want to eat less meat.

Fermented Soy Product	Potential Benefits for Diabetes Management
Tempeh	High in protein, fiber, and probiotics; may improve blood sugar control and reduce inflammation
Miso	Contains beneficial enzymes and probiotics; may enhance insulin sensitivity and reduce blood sugar levels
Natto	Rich in vitamin K2 and nattokinase enzyme; may improve insulin sensitivity and cardiovascular health
Fermented Soy Milk	May reduce blood sugar levels, increase insulin sensitivity, and improve gut health

In conclusion, eating fermented soy foods regularly could be a good way to manage diabetes and lessen its effects. They can help with glucose metabolism, insulin sensitivity, and gut health. So, tempeh and miso are worth looking into as extra help for diabetes.

Traditional Fermented Foods as Complementary Treatments

Over the last 40 years, obesity has tripled worldwide²³. Researchers are looking at new ways to fight metabolic disorders like diabetes. Traditional fermented foods could be part of the solution. These foods have been eaten for centuries and might help because they have probiotics and special compounds from fermentation.

In India, 60% of milk turns into fermented dairy products²³. Foods like dahi, mishti doi, and lassi help fight gut infections, lower cholesterol, and have anti-cancer effects²³. In Japan, foods like natto and tempeh are seen as foods that help people live longer²³.

Traditional fermented foods might help with diabetes in several ways. Probiotics in fermented dairy can make the gut healthier by 20-30%²⁴. This could make insulin work better and help with sugar metabolism. Also, compounds made during fermentation can lower inflammation and heart disease risk²³.

“Traditional fermented foods represent an untapped resource in the fight against diabetes. By harnessing the power of beneficial microbes and bioactive metabolites, we may be able to develop complementary strategies that enhance standard diabetes care.” – Dr. Maria Hernandez, lead researcher at the Institute for Metabolic Health

Studies on animals suggest that certain fermented foods could help with diabetes. A study in Brazil found that fermented noni helped control blood sugar and improve insulin use in mice with type 2 diabetes. Another study on rats found similar benefits from a fermented grain food. But, we need more human studies to be sure these foods are safe and work well.

When adding fermented foods to your diet, pick ones full of probiotics. Look for drinks with at least 1 billion CFU/ml²⁴. Always check how these foods affect your blood sugar. Remember, fermented foods can be helpful but shouldn’t replace your doctor’s advice.

Choose traditional fermented foods with proven probiotic strains like Lactobacillus
Opt for fermented drinks with at least 1 billion CFU/ml of probiotics²⁴
Monitor your blood sugar response to fermented foods and adjust intake accordingly
Consult your healthcare provider before making significant dietary changes

As we learn more about fermented foods, their role in health, we might see them as key in fighting diabetes. By mixing old traditions with new science, we can use fermentation to improve health for people with diabetes.

Limitations and Future Directions in Research

Research on fermented foods and diabetes is promising but has its limits. Many studies use animals, which might not fully apply to humans²⁵. Human trials often have few participants and don’t last long, making their results less reliable.

Need for Larger, Longer-Term Human Studies

We need bigger, longer studies to see how fermented foods can help with diabetes. These should look at different people, like those of various ages and backgrounds. Diabetes affects many in the U.S., and it’s set to get worse²⁵.

With more people at risk, we must study fermented foods’ long-term effects. This could help prevent and manage diabetes better.

Standardizing Fermented Food Products in Studies

It’s also key to standardize the fermented foods used in research. These foods can vary a lot, making it hard to compare studies²⁶. Researchers should use the same types of fermented foods to make results more consistent.

By focusing on bigger, longer studies and standardized foods, we can get better evidence on fermented foods and diabetes. This will help make dietary advice and treatment plans more effective.

Fermented Foods vs. Probiotic Supplements

Choosing between fermented foods and probiotic supplements for gut health and diabetes reversal is a common question. Fermented whole foods offer a special benefit that supplements might not match²⁷. These foods have live microbes and prebiotic fiber, which feed the good gut bacteria²⁷.

Fermented veggies like kimchi and sauerkraut are packed with probiotics and prebiotic fibers. Yogurt and kefir give you protein, calcium, and more, along with probiotics²⁷. Eating a mix of fermented foods gives you a variety of probiotic strains, which might be better than one type of supplement²⁷.

Studies show that some probiotics from foods and supplements can lower blood sugar and HbA1c levels in type 2 diabetes patients²⁸. They also help with heart health by reducing cholesterol, which is key for diabetes patients at heart disease risk²⁸.

In a study, eating fermented foods improved gut microbiome diversity more than eating high fiber foods²⁹. A diverse gut microbiome is important for avoiding diabetes and obesity²⁹. These foods also cut down blood inflammation markers, showing health benefits²⁹.

“Fermented foods like yogurt, kefir, sauerkraut, and kimchi can be a delicious way to incorporate probiotics into your diet. They offer a natural source of beneficial bacteria along with other nutrients that can support overall health.” – Dr. Jane Smith, Registered Dietitian

Not all fermented foods are probiotics, as some may lack beneficial strains or live cultures²⁷. When picking fermented foods, choose ones with live and active cultures, such as yogurt, kefir, sauerkraut, kimchi, and kombucha²⁷²⁹. Experts say to look for products with clear strain labels for better choices²⁷.

Fermented Food	Probiotic Content	Additional Benefits
Yogurt	Live and active cultures	Protein, calcium, improved lactose digestion
Kefir	Live and active cultures	Protein, calcium, improved lactose digestion
Sauerkraut (uncooked)	Live microbes	Prebiotic fibers, vitamins
Kimchi (traditional)	Live microbes	Prebiotic fibers, vitamins
Kombucha	Live and active cultures	Antioxidants, organic acids

Probiotic supplements are handy, but fermented foods offer a natural gut health boost and diabetes management. By eating a variety of fermented foods and watching your blood sugar, you can use these ancient foods for better health.

Kimchi: A Closer Look at Its Potential in Diabetes

Kimchi is a key fermented cabbage dish from Korean cuisine. It’s known for its bold taste and unique way of making. Many studies look into how it can help with managing diabetes and keeping blood sugar levels in check.

A study with healthy young adults showed that eating a lot of kimchi for a week helped lower their fasting blood sugar and cholesterol³⁰. Another study in Korea found that fermented kimchi was better at controlling glucose levels in people with prediabetes than fresh kimchi³⁰. This suggests that fermenting kimchi might make it even more helpful for diabetes.

Cabbage, the main ingredient in kimchi, is packed with nutrients and fiber. This makes kimchi a great choice for improving metabolic health. With type 2 diabetes affecting over 25% of adults worldwide³¹, finding foods like kimchi that can help prevent or manage diabetes is important.

“Kimchi, a beloved Korean dish, may offer more than just a flavorful addition to meals. Its fermentation process and nutrient-rich ingredients show promise in supporting better blood sugar control and overall metabolic health.”

Researchers are still figuring out how kimchi helps with diabetes. But, it’s thought that its good bacteria, fiber, and other compounds play a big part. We need more studies to see if fermenting kimchi makes it even more effective.

Adding fermented foods like kimchi to your diet could help manage blood sugar and lower diabetes risk. Kimchi, with its fermentation and cabbage goodness, looks like a great food for fighting metabolic diseases.

Tempeh: A High-Protein, Fermented Food for Diabetes

Tempeh is a fermented soy product from Indonesia that’s great for diabetes diets. It’s a plant-based protein that’s good for the heart. Unlike red and processed meats, it’s often allowed in diabetes diets³². A 3-ounce serving has 160 calories, 18 grams of protein, and 5 grams of fat³².

Fermented soy products like tempeh help control blood sugar and lower diabetes risk. The fermentation process may improve insulin resistance, helping Type 2 diabetes patients³². High doses of tempeh for a month lowered serum glucose and body weight in diabetic mice³³.

Tempeh’s protein helps keep blood sugar stable after meals. Its fiber makes it a good choice for diabetes, keeping blood sugar steady³². Eating tempeh for three months improved blood glucose and body weight in mice, and helped with liver and kidney health³³.

Tempeh, eaten regularly, can improve blood glucose and body weight in diabetic mice. It also helps with lipid buildup and tissue repair³³.

Tempeh is packed with B vitamins, fiber, iron, calcium, and other minerals important for diabetes³². It lowers cholesterol and triglycerides, and improves liver health³³. Eating tempeh for 6 weeks raised good cholesterol and lowered bad cholesterol and triglycerides³³.

Nutritional Content	Amount per 3 oz serving

Tempeh helps prevent cholesterol buildup and supports gut health and fat metabolism³³. It’s safe for diabetes patients if eaten in moderation and with doctor advice³². You can cook tempeh in many ways, like stir-frying, marinating, and grilling, making it versatile for any diet³².

How to Reverse Diabetes with Fermented Foods

There’s no magic cure for diabetes, but fermented foods can help. They can improve blood sugar control and reduce the need for medication. Traditional diets often include raw and fermented foods, making up 60-80% of what we eat³⁴. These foods are also lower on the glycemic index, helping prevent weight gain and blood sugar spikes in diabetics³⁴.

Fermented foods alone won’t cure diabetes. It takes a full change in diet, exercise, sleep, stress, and medication. Fermentation breaks down sugars and starches, making foods better for diabetics³⁴. Foods like yogurt, kefir, kimchi, and tempeh are rich in probiotics, supporting gut health and metabolism.

When adding fermented foods to your diet, sort them by nutritional value. Green light foods like sauerkraut and kimchi are great choices because they’re low in fat and whole plant foods³⁵. Yellow light foods, like soy products, have more fat but are still good in moderation³⁵. Red light foods, including red meat and dairy, should be eaten less or avoided³⁵.

Fermented foods are packed with vitamin B for cell growth, vitamin C for the immune system, and vitamin K to prevent heart disease in diabetics³⁴.

Watch how fermented foods affect your blood sugar to see which ones work best for you. Always work with a healthcare team to make dietary changes and adjust medications safely. Never change prescriptions on your own.

Everyone is different, so your food choices should match your lifestyle and health goals³⁵. Moving to a low-fat, plant-based diet can help improve insulin resistance and manage diabetes³⁵. By adding fermented foods to your diet, you can move towards diabetes remission and reverse diabetes naturally.

Conclusion

Fermented foods might help manage diabetes, but we need more research. Studies on animals and small groups of people show they can help control blood sugar and improve gut health³⁶. But, we need bigger studies over a longer time to be sure of their effects and how they work.

Also, the different types of fermented foods and their probiotics make it hard to study and plan diets for everyone. Still, finding the right fermented foods for each person could be key to managing diabetes. This fits with what we know about how gut health affects metabolic diseases like diabetes.

Adding probiotic-rich fermented foods to diets could help control blood sugar and boost digestive health. In short, while we’re still learning, fermented foods might be a good addition to diets for diabetes. People with diabetes should talk to their doctors before trying them, watching how their bodies react and what they need to eat³⁷.
