If you’ve ever eaten a ripe, freshly cut pineapple you probably won’t need much persuasion to consume more. But you may be pleased to learn that this aromatic tropical fruit offers several health and beauty benefits in addition to its delicious flavor. In this article, we will discuss the top 5 pineapple benefits.
Top 5 Pineapple Health and Beauty
- Better skin
- Prevents oxidative stress
- Protects against cell mutation
- Improves digestion
- Improves blood glucose levels
Pineapple Improves Skin Health
Pineapple can improve your skin’s health because of its high vitamin C content. “One cup [(165g)] of fresh pineapple chunks provides 131% of your vitamin C needs for the day…”1 Vitamin C, also known as ascorbic acid, is vital to skin health, because of the role it plays in collagen synthesis.
Collagen is the main structural protein in cells, tissues and organs; it’s the most abundant protein in the human body, and actually holds the entire body together. Even our bones contain collagen. And both dietary and topical vitamin C have other beneficial effects on skin cells.
“Some studies have shown that vitamin C may help prevent and treat ultraviolet (UV)-induced photodamage. However, the effects of vitamin C in the skin are not well understood due to limited research.”2
Pineapple Prevents Oxidative Stress & Protects Against Cell Mutation
Vitamin C is also an important and powerful dietary antioxidant. Antioxidants neutralize free radicals and protect our bodies.
“If free radicals overwhelm the body’s ability to regulate them, a condition known as oxidative stress ensues. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases.”3
Many of the diseases caused by free radicals are the result of cell damage and mutation.
“Numerous investigators have proposed participation of free radicals in carcinogenesis, mutation, and transformation; it is clear that their presence in biosystem could lead to mutation, transformation, and ultimately cancer. … Antioxidants can decrease oxidative stress induced carcinogenesis by
a directscavenging of [reactive oxygen species] and/or by inhibiting cell proliferation secondary to the protein phosphorylation.”3
Free radicals are a natural byproduct of human metabolism. Fortunately, whole foods, like pineapple, are rich in the nutrients needed to neutralize those harmful byproducts and maintain our good health.
Pineapple Improves Digestion & Blood Glucose
Pineapples are also great for digestion and alleviating/preventing constipation, because of their fiber and water content. One cup of fresh pineapple contains 2.3 grams of fiber. 1 whole fresh pineapple contains 13 grams, which is more than half (52%) the recommended daily allowance for dietary fiber. Oddly enough, frozen pineapple contains 2.7 grams per cup, according to the USDA Nutrient Data Laboratory. Pineapple contains both soluble and insoluble fibers, and both are beneficial to digestion.
Soluble fiber attracts water and turns it into a gel during digestion, which slows digestion. This form of fiber has been shown in studies to lower both blood cholesterol and glucose levels.
“In people with diabetes, fiber — particularly soluble fiber — can slow the absorption of sugar and help improve blood sugar levels. A healthy diet that includes insoluble fiber may also reduce the risk of developing type 2 diabetes.”4
Insoluble fiber cannot be broken down by water; it adds bulk to the stool and helps food pass through the stomach and intestines with greater ease. This will increase regularity and prevent constipation and hemorrhoids. Insoluble fiber may also prevent the development of small pouches in your colon (diverticular disease). When those pouches become inflamed, the condition is called diverticulitis.
“Ten to 25 percent of people with diverticulosis get diverticulitis. As many as one American in 10 over the age of 40 has diverticulosis; about half of all people over 60.”5
Regularly consuming whole foods, like pineapples, which are rich in fiber, could greatly decrease those numbers in all age groups.
Pineapple Nutrition – Fresh and Canned
I LOVE fresh pineapple, the flavor cannot be beat, but you can also benefit nutritionally from eating canned and frozen. I should mention, however, that frozen pineapple does not taste nearly as good as fresh, or even canned. Canned pineapple is a close second in flavor, and it does contain a little more of some nutrients. This is due to canned pineapple being packed in fruit juice. And the addition of juice means more carbohydrates, more sugar, more calories, and even a little more fiber.
Canned pineapple contains 2.4 grams of fiber, only a little bit more than fresh. The carbs, calories and sugar are a different matter. 21.7grams of carbohydrates fresh, versus 28.2grams of carbohydrates canned; 16.3grams of sugar fresh, versus 25.6grams of sugar canned; and 82 calories fresh, versus 109 calories canned.
For me, that’s a lot of extra sugar, and it makes me wonder why fresh pineapple tastes so much sweeter than canned. But your priorities may differ, and getting more fiber and carbohydrates may matter more than those other factors.
In any case, when you eat pineapple, whether it’s frozen, canned or freshly sliced, you now know you are eating a food that is very nutritious, health-promoting as well as delicious.
