Gallotannins

Gallotannins are a group of substances belonging to the class of tannins, which are widely distributed in nature, especially in the plant kingdom. These compounds have the ability to bind and precipitate proteins, making them important for practical applications in medicine and the food industry.

Gallotannins are found in many plants, including oak, sumac, and some fruits and nuts. They impart an astringent taste to some foods, such as tea, wine, and certain fruits.

In medicine, gallotannins are studied for their potential in treating and preventing various conditions, such as diarrhea, gastritis, and even some forms of cancer. Their antibacterial properties also make them interesting for the development of new antibiotics.

Gallotannins in the context of the keto diet

From the perspective of the keto diet, gallotannins are particularly interesting because of their impact on carbohydrate metabolism. Despite not containing carbohydrates themselves, gallotannins can influence the rate of carbohydrate absorption from food and, consequently, blood sugar levels. This is due to their ability to bind carbohydrates and slow their absorption in the digestive tract.

Benefits of gallotannins:

• May contribute to a more stable blood glucose level.
• Help control appetite, which is beneficial for following the keto diet.
• Their antioxidant properties help combat oxidative stress.

However, considering that the keto diet requires strict control over carbohydrate intake, products rich in gallotannins, such as fruits, should be consumed in limited quantities or completely excluded from the diet to avoid exceeding the permissible carbohydrate level.

On the keto diet, you can include in your diet some products containing gallotannins, provided that their carbohydrate composition meets the requirements of the ketogenic diet. These products include:

• specific types of berries, such as blueberries and blackberries;
• nuts and seeds, such as almonds and sunflower seeds.

In conclusion, gallotannins can play a positive role in the nutrition of individuals following the keto diet, but their consumption should be balanced and moderate to meet the requirements of a low-carb diet.
