Sources are garlic, onion, apple, oats, flaxseed, banana. Bananas supply your gut with inulin, a type of fiber that helps good bacteria grow.

It also leads to gut dysbiosis which is an imbalance of the gut microbiome. Excessive use of artificial sweeteners may increase blood sugar levels due to their effect on gut microflora. So it’s better to avoid sweeteners as well.

2. Avoid processed foods - They affect the gut composition and also upset the microbe metabolism. Highly processed foods are devoid of nutrition and therefore have poor effect on the gut microbiome.

3. Red Meat - Red meat has L-carnitine which when consumed in excess can change gut microflora and also releases an inflammation causing carbohydrate. It also leads to increased risk of heart disease due to its high saturation of fat and cholesterol.

6. Antibiotics - Antibiotics can’t tell the difference between good and bad bacteria, so they kill all of them and thus alter the gut microbes.

4. Smoking – It impacts the large bowel and has a significant influence on gut microbiota composition. It increases Bacteroides-Prevotella in individuals with Crohn’s Disease and healthy individuals.

5. Physical activity – Studies have shown that exercise has protective effects on gut health and it helps reduce the risk of colon cancer, diverticulosis and inflammatory bowel disease. Lack of exercise can alter the gut bacteria composition. Overall exercise is beneficial as it helps reduce metabolic syndrome as well.
