When you consume less fibre than the daily permissible limit, it will tend to increase the blood sugar levels in your body. As per Mayo Clinic, the daily fibre recommendation varies for men & women. While for an average adult man, the fibre intake should be between 30-38 grams, while an adult woman must consume somewhere between 21-25 gms of dietary fibre. Fibre is one nutrient that not only reduces the blood sugar levels in your body but also promotes digestive health while lowering the risk of several lifestyle diseases such as diabetes and heart diseases.
