The international media "LiveScience" pointed out that pineapple is rich in vitamins, digestive enzymes and antioxidants. Although it is sweet, the calories are still very low. Laura Flores, a professor of nutrition, pointed out that the most prominent nutritional advantage of pineapple is that it contains a lot of trace elements such as vitamin C, dietary fiber, bromelain, manganese and thiamine. A serving of pineapple has only 74 calories, and it has no fat and cholesterol-of course, this means that fresh pineapple can't be counted.
What are the nutritional values of pineapple?
What are the nutritional benefits of eating pineapple? According to the research of Oregon State University, pineapple is a water-soluble antioxidant, which can repair cell damage, because it contains a lot of vitamin C, which has positive benefits in preventing heart disease and joint pain. In addition, pineapple enzyme can reduce excessive blood coagulation, and moderate consumption can reduce the risk of thrombosis. In addition, pineapple contains high manganese, which is an important element for the health of bones and connective tissues. Manganese and other trace elements can also prevent osteoporosis in menopausal women.
Although eating pineapple alone may not cure floaters, pineapple can reduce the risk of macular degeneration. Professor Flores explained that pineapple contains a lot of antioxidants and vitamin C, which is really good for eye health. In addition, bromelain is a strong anti-inflammatory substance, which not only helps to alleviate arthritis, but also proves that proteolytic enzymes such as bromelain can improve the survival rate of cancer in animal experiments. Like other vegetables, pineapple is also rich in dietary fiber, which helps to maintain the normal operation of the stomach.
A study by the University of Maryland Medical Center pointed out that bromelain can reduce mucus secretion in the throat and nasal cavity, and at the same time, it can also relieve cough. If you have nasal allergies or sinusitis, you can also consider eating more pineapples to alleviate allergic symptoms.
What harm can pineapple do if you eat too much?
Pineapple has many benefits. Is it safe to eat regularly? Flores warned that eating too much pineapple at one time can easily lead to oral pain and allergic reactions of lips, tongue and cheeks (or oral allergy syndrome, which may be caused by protein with similar pollen structure in pineapple peel). In severe cases, it may also lead to rash, urticaria and even dyspnea, all of which are symptoms of pineapple allergy.
In addition, pineapple has a high content of vitamin C. Excessive intake of vitamin C may also cause diarrhea, nausea, vomiting, abdominal pain, heartburn and other symptoms, as well as excessive intake of pineapple enzyme. Therefore, although pineapple is not low in nutritional value and suitable for normal intake by the public, it is best not to eat it in large quantities at one time. If you have an allergic reaction that does not subside naturally within a few hours, you must see a doctor.
