If there is one nutrient worth paying attention to, it might be fiber. It feeds the good bacteria in your gut, keeps digestion regular, helps you feel full and supports steady blood sugar and healthy cholesterol.
How much is enough?
The recommendation is 14 g of fiber for every 1,000 calories you eat. That works out to about 25 g a day for women and 38 g for men, a little less after age 50.
Yet only about 7% of adults reach it: roughly 9% of women and 5% of men. Average intake is closer to 9 or 10 g per 1,000 calories.
Where fiber lives
Fiber only comes from plants. Meat, fish, eggs and dairy have none. Good sources include:
- Beans and lentils: about 8 g per cooked cup, the champions.
- Whole grains: oats, barley, brown rice, whole-wheat bread.
- Vegetables: broccoli, carrots, Brussels sprouts, leafy greens.
- Fruit with skin: apples, pears, berries.
- Nuts and seeds: almonds, chia, flax.
Five small swaps
- Choose oats or a high-fiber cereal at breakfast instead of a refined one.
- Add a handful of beans or lentils to soups, salads and sauces.
- Pick whole-grain bread and pasta.
- Keep fruit and a small bag of nuts for snacks.
- Fill half your plate with vegetables at lunch and dinner.
Go slowly
Raising fiber quickly can cause bloating. Add a few grams every few days and drink enough water, since fiber works best with fluid.
