Final answer:
The Adequate Intake (AI) for total fiber for adults is generally recommended to be 25 grams per day. Adult men under 50 should aim for 38 grams per day. Whole grains, legumes, vegetables, and fruits are key for meeting fiber needs.
Step-by-step explanation:
The Adequate Intake (AI) for total fiber varies depending on age and gender, but for adults, the Institute of Medicine provides general guidelines. Adult women under the age of 50 should aim for 25 grams per day of fiber, while adult men under the age of 50 should aim for 38 grams per day. However, for general purposes, such as the information provided on Percent Daily Values on food labels which are based on a 2,000 calorie diet, the recommended daily fiber intake is often set at 25 grams per day for adults. This is intended to promote good health and may help in the prevention of various health issues, including coronary heart disease, colon cancer, and type 2 diabetes.
To ensure a proper intake of dietary fiber, incorporating whole grains, legumes, vegetables, and fruits into the diet is advised. Foods like pears and avocados, which contain about 5 grams of fiber and 12 grams of fiber respectively, are excellent choices. Looking at food labels and online fiber counters can help track your daily intake to ensure adequate consumption.
