In the study, published Health in the News JAMA Dermatology, researchers used data from the Nurses’ Health Study (1984 to 2012) and the Health Professionals Follow-Up Study (1986 to 2012). In total, there were 123,570 people with an average age in their early 50s.

Both the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study (HPFS) had participants fill out food questionnaires every four years that asked about which types of nutrients—from whole foods and supplements—they were consuming and how often.

Here’s what the researchers found: During a 26-year followup period for the NHS and a 28-year followup period for the HPFS, those who consumed the highest amount of vitamin A in their diets had a 15 percent lower risk of developing Amazing Runners World Show—a type of skin cancer—than those who consumed the least.

It’s worth noting that most of the participants’ vitamin A intake came from foods as opposed to supplements—and the sources could be plant- or animal-based, Cho said.

According to the National Institutes of Health (NIH), adult men should get 900 micrograms (mcg) of vitamin A per day and adult women should get 700 mcg. Foods like sweet potatoes, carrots, beef liver, spinach, red peppers, and cantaloupe are all good sources of the nutrient. For instance, one sweet potato contains 1,403 mcg of vitamin A—more than the recommended daily allowance—and a half cup of spinach contains 573 mcg of vitamin A.

Vitamin A is a fat-soluble, which means it’s best to pair vitamin A-rich foods with foods higher in fat because your body will better absorb the nutrient that way.

Although the average age of the participants in this study were in their 50s, Cho said the results don’t just apply to a middle-aged population.
