Data continues to suggest that vitamin A is crucial for healthy growth of skin cells. The study, though, advises that those who have the highest average daily total intake of vitamin A were, at least, 17 percent less likely to develop skin cancer than those with the lowest total vitamin A intake. In addition, the team found the majority of Vitamin A came from dietary sources, especially in the form of natural fruit and vegetables (as opposed to animal-based foods and vitamin supplements.
To determine these statistics, the research team analyzed a pair of long-term observational studies that looked at 121,700 US women, between 1984 and 2012 and about half as many men (51,529) between 1986 and 2012. From this data, the researchers examined diet and skin cancer results to find that roughly 123,000 study participants were white and had no prior history of skin cancer. This is important because lighter skin tends to be more vulnerable to skin cancer.
Out of all those who participated, the study identified 3,978 cases of squamous cell carcinoma within the 24 to 26 year follow-up periods.
Considering all of these things, it is also important to keep in mind that the research team grouped all of the participants into five varying categories of Vitamin A intake. Sure enough, the highest level of Vitamin A intake had significantly better reduction in skin cancer risk than the lowest level of Vitamin A intake. To clarify, though, health experts advise that adults should not consume more than 900 micrograms of Vitamin A per day—in dietary supplement form—and no more than 700 micrograms, per day, in a natural form.
That in mind, here are some of the best natural sources of vitamin A to serve your health. And fortunately, these are also pretty easy to find at your grocery produce department or a local farmer’s market: Indian gooseberry, tomato, papaya, apricots, sweet potatoes, cantaloupe, carrots, and leafy green vegetables (spinach, kale, etc). Some animal sources of vitamin A include milk, liver, and some types of fish.
