Myth: You should avoid dairy as you get older.
Truth: Only if it aggravates your stomach or digestive system.
Our bodies often become less tolerant of certain foods as we get older, says Johnson. Dairy is one of them because production of the enzyme lactase, which aids in the digestion of dairy, decreases as we age.
But unless you’re not feeling well after having dairy products (symptoms such as gas and bloating), there’s no need to start shunning dairy.https://www.hopkinsmedicine.org/health/wellness-and-prevention/nutrition-what-you-need-to-know-for-healthy-aging
