Jackie Newgent, a New York–based culinary nutritionist and the author of ‘The All-natural Diabetes Cookbook’ has said that, “The standout nutrient in pineapple is vitamin C, which supports the immune system and provides antioxidant benefits.”
One cup of pineapple contains 78.9mg of vitamin C, according to the US Department of Agriculture. That’s more than the recommended dietary allowance for adult women (which is 75mg per day) and close to the recommendation for men (90mg per day), according to Medlineplus. Vitamin C is important because it encourages growth and healing around the body and plays a role in a lot of things, from wound repair to iron absorption. Also, pineapple contains bromelain, which is a mix of enzymes, that studies show can reduce inflammation and nasal swelling, and also aid in the healing of wounds and burns, according to the National Centre for Contemporary and Integrative Health. It has also been linked to improved digestion and has historically been used in Central and South American countries to treat digestive disorders.
