常见问题
What are the types of fiber?
Soluble fiber (dissolves in water, found in oats, beans) helps lower cholesterol. Insoluble fiber (found in whole grains, vegetables) aids digestion. Both are important.
Does fiber have calories?
Fiber provides about 2 kcal per gram (less than other carbs) because it is only partially fermented in the gut.
Can I eat too much fiber?
Yes, excessive fiber (over 70 g/day) can cause bloating and gas. Increase intake gradually and drink plenty of water.
