What's funny is that the folks who go on and on about protein (which you correctly pointed out is NOT an issue for most people) seem oblivious to the fact that what most people actually ARE deficient in is fiber. Especially in the US.
This is from Grok:
United States Fiber Deficiency
In the U.S., the data is clearer and paints a stark picture. The National Health and Nutrition Examination Survey (NHANES) and other studies consistently show that most Americans don’t get enough fiber:
- Only 5% of men and 9% of women meet the recommended daily fiber intake (25–30 grams for adults, varying by age and sex), meaning 91–95% of U.S. adults are fiber-deficient.
- Average intake is about 15 grams/day for adults, roughly half the recommended amount.
- NHANES data (2013–2018) shows women consume ~9.9 grams/1,000 kcal and men ~8.7 grams/1,000 kcal, far below the guideline of 14 grams/1,000 kcal.
- Fiber deficiency is worse among certain groups, like non-Hispanic Black adults (7 grams/1,000 kcal vs. 9.2 for Hispanics in 2017–18).
Why It Matters
Low fiber intake is linked to higher risks of heart disease, diabetes, obesity, and colorectal cancer, making it a public health priority. In the U.S., the gap is attributed to low consumption of fruits, vegetables, and whole grains, plus reliance on processed foods.
But let's keep worrying about protein! ;p
