Why YSK: fiber is important for optimal human health. It helps us avoid diabetes, heart disease, colon cancer, obesity, and other diseases. This is particularly important in developed countries such as mine (USA) that are suffering greatly from these diseases.
The recommended daily fiber intake is 25g for women and 38g for men in the USA, and 95% of us don’t meet this amount. This suggests an urgent need for us to increase our daily fiber intake, which can be achieved by swapping out ultra-processed foods and animal foods that are void of fiber with whole plant foods such as fruits, vegetables, legumes, whole grains, nuts, and seeds.
In general, American men are larger - dimensionally - so more fibre is required for a larger person.
Ideally, an individual would work with their doctor or whoever to figure out how much would be appropriate.
