Is milk good for digestion?

Quick answer

The NIH (NIDDK) does not say milk improves digestion. For people who cannot fully digest lactose, milk can cause bloating, gas and diarrhea. NIDDK says many people can still have about 12 grams of lactose, roughly 1 cup of milk, with no or mild symptoms.

Does milk help digestion?

The NIH National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) pages we read state no digestive benefit of milk. They describe milk as a main source of calcium, vitamin D and other nutrients, and they warn that dropping dairy completely can leave you with less calcium and vitamin D than you need.

Why does milk upset some stomachs?

Milk contains lactose. In lactose malabsorption the small intestine cannot break down all of it. NIDDK names bloating, diarrhea and gas as the symptoms. It says about 68 percent of the world’s population has lactose malabsorption and about 36 percent of people in the United States. Not everyone with malabsorption has symptoms.

How much milk can people with lactose intolerance have?

NIDDK says many people can have about 12 grams of lactose, roughly 1 cup of milk, with no symptoms or only mild ones. Ways to tolerate dairy better are drinking small amounts with meals, adding dairy gradually, or using lactase products.

Are lactose-free milk, yogurt and cheese easier to digest?

NIDDK says lactose-free and lactose-reduced milks are just as healthy as regular milk and milk products. It also says yogurt and hard cheeses such as cheddar or Swiss have less lactose than other dairy products, and some people find them easier to digest.

What about almond milk?

The NIDDK pages we read say nothing about almond milk and digestion. They list fortified soy milk, not almond milk, among non-dairy calcium sources. If digestive symptoms continue, talk to a doctor.
