Type 2 diabetes makes it difficult for the body to use insulin effectively, leading to high blood sugar levels. Disease control requires a combination of medications, diet, lifestyle changes and, in some cases, functional foods. However, some seemingly harmless functional foods can affect blood sugar levels or interact with medication.
According to Dr. Sarika N Holla, general practitioner and Endocrinologist at Kinder Hospital, Bangalore (India), people with type 2 diabetes need to be careful when using functional foods. Here are 5 types that should be limited:
Vitamin E
Vitamin E is known as an antioxidant, good for the skin and immune system. However, at high doses, vitamin E can increase the risk of bleeding and interact with blood thinners commonly used for people with diabetes. In addition, research shows that high doses of vitamin E can aggravate insulin resistance, making blood sugar levels more difficult to control.
Vitamin B3 (Niacin)
Niacin supports cholesterol metabolism and control. However, for people with diabetes, vitamin B3 can reduce insulin sensitivity, leading to sudden increases in blood sugar. If you need to use niacin to treat cholesterol, you should consult your doctor for a safer alternative.
Crom
chromium is often promoted as a mineral that helps control blood sugar, but excessive supplementation can be harmful. People with type 2 diabetes who supplement chromium without instructions are at risk of kidney problems, stomach upset and blood sugar fluctuations.
Protein powder has a high glycemic index
Some protein powders contain added sugars or carbohydrates with a high GI, causing blood sugar levels to spike. People with diabetes should choose isolated whey protein powder or unsweetened plant protein, while prioritizing protein sources from whole foods such as eggs, beans, lean meat and nuts.
Alpha-Lipoic acid (ALA)
ALA is often used to support nerve health, especially for people with diabetes and neurological diseases. However, ALA can lower blood sugar too quickly or interact with diabetes medications, leading to dangerous hypoglycemia. In addition, ALA is not ideal for people with thyroid disease.
Safer alternatives
Functional foods should only be used when there are diagnosed deficiencies. Some safer measures for people with type 2 diabetes include:
Eat a balanced diet rich in fiber
Regular physical activity
Providing enough water
Manage stress
Maintain quality sleep
Note
Dr. Sarika N Holla says that while functional foods can support health, for people with type 2 diabetes, some products can aggravate blood sugar or interact with drugs.
Always consult your doctor before supplementing any functional foods to ensure safety and effectiveness in disease control.
