Researchers link high potassium intakes to a reduced risk of stroke , protection against loss of muscle mass, preservation of bone mineral density, and reduction in the formation of kidney stones. The antioxidant vitamin C, when eaten in its natural form or applied topically, can help to fight skin damage caused by the sun and pollution, reduce wrinkles, and improve overall skin texture.
Vitamin C also plays a vital role in the formation of collagen , the support system of the skin. Select a pineapple with a firm, plump body, without bruising, or soft spots and with green leaves at the crown. A green outer shell does not mean the pineapple is not ripe and, contrary to popular belief, neither does the ease in which the leaves pull from the crown. Pick pineapples at their peak ripeness.
Unlike other fruits, they will not continue to ripen once picked. Whole pineapples should be stored at room temperature, while cut pineapples should be stored in the refrigerator.
When eating canned or packaged pineapple, make sure to pick up the varieties canned in pineapple juice, not heavy syrup. Beta-blockers , a type of medication most commonly prescribed for heart disease, can cause potassium levels to increase in the blood. High potassium foods should be consumed in moderation when taking beta-blockers. Consuming too much potassium can be harmful to people whose kidneys are not fully functional.
If your kidneys are unable to remove excess potassium from the blood, it could be fatal. Those with gastro-esophageal reflux disease GERD may experience an increase in symptoms, such as heartburn and regurgitation, when consuming highly acidic foods. However, individual reactions vary. Focus on keeping the overall diet varied and adding a range of nutrients to the overall diet, rather than specific foods.
In this Honest Nutrition feature, we explore the practice of "clean eating," and why this concept has been a controversial one for researchers. A recent study found several phthalates and other plasticizers in food items from leading fast-food chains, highlighting the need for more regulation. This article looks at the causes of postprandial somnolence, or food coma, and explains how people who often feel sleepy after eating can cope with….

Pineapple may help you keep standing tall and strong. One cup of raw pineapple chunks contains 2. A study suggested that manganese, along with other trace minerals, may be helpful in preventing osteoporosis in post-menopausal women. The variety of vitamins and minerals in pineapples have many other health benefits, too. For example, " pineapples can help reduce the risk of macular degeneration , a disease that affects the eyes as people age, due in part to its high amount of vitamin C and the antioxidants it contains," Flores said.
Like many other fruits and vegetables, pineapple contains dietary fiber , which is essential in keeping you regular and in keeping your intestines healthy, according to the Mayo Clinic. But unlike many other fruits and veggies , pineapple contains significant amounts of bromelain, an enzyme that breaks down protein, which may help with digestion, according to the American Cancer Society.
Multiple studies have suggested that bromelain could also be helpful in treating osteoarthritis. Excessive inflammation is often associated with cancer, and according to the Memorial Sloan Kettering Cancer Center , bromelain and other proteolytic enzymes have been shown to increase the survival rates of animals with various tumors. Flores noted that because of their bromelain levels, pineapples can help reduce excessive coagulation of the blood.
This makes pineapple a good snack for frequent fliers and others at risk for blood clots. In addition to having lots of vitamin C, pineapple's bromelain may help reduce mucus in the throat and nose, according to the University of Maryland Medical Center.
Pineapple also delivers some fiber 2. 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 NCCIH. A study published in Biotechnology Research International found that the bromelain in pineapple may help reduce the effects of diarrhea.
Along with calcium, the trace mineral manganese is essential for maintaining strong bones, according to the University of Rochester Medical Center. Pineapple is one of the top food sources of the mineral, according to Oregon State University — a single cup of pineapple contains about 76 percent of the recommended daily value of manganese. Manganese may help stave off osteoporosis and helps improve overall bone and mineral density, according to Oregon State University.
Be careful not to overdo it, though — manganese intake can be dangerous and may increase the risk of cognitive disorders if you consume more than 11 mg per day, according to a study published in The Open Orthopaedics Journal.
According to a study published in June in Molecules , pineapple is a great source of antioxidants, specifically phenolics, flavonoids, and vitamin C. Filling up on antioxidant-rich foods like pineapple can play a role in countering those risks.
Cancer occurs when abnormal cells in the body multiply and take over the healthy tissue, according to the Mayo Clinic.
