Understanding Lactose Intolerance: Causes andd Prevalence

Calcium is mest abpentant mineral in the body and is critial for bone structure, muscle contraction, nerve transmissionon, blood clotting, and contribute secretion. The recommended dietary allowance (RDA) for calcium ranges from 1,000 to 1,200 mg per day for diults, with higher neds during empance, curnance, and lactation. Dairy products provide about 70% of dietary calcium in thee typical U.S.diet. Withatte cate calun.

Routine monitoring of serum 25- hydroksycolin D levels is advisable for highrisk groups.

For individuals who avoid dairy, protein intake can e maintained through leun meats, poultry, fish, eggs, legumes, nuts, seeds, soy products (tofu, tempeh, edamame), and whole grains.
