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.
Do not jump straight to this fiber intake if you are eating way under it. Gradually alter your diet to meet it. You will experience some discomfort if you don't.
You know that old saying an apple a day keeps the doctor away? Apples are a great source of fiber.
