Pineapple And Health: The Facts And Top Benefits Of Pineapple On Your Health
Saturday, March 25, 2017
Pineapple, the tropical fruit for excellence, is available all year in our supermarkets.
Very rich in manganese, it contains mainly bromelain, which would have many health virtues, among others, on the blood circulation and cardiovascular diseases.
The Benefits of Pineapple
Clinical observations and several studies based on animal and cellular models suggest that bromelain, an enzyme contained in pineapple, may have a direct effect on cancer cells and their microenvironment. They would have, among other things, an effect in the regulation of the immune, inflammatory and hemostatic systems (favoring blood clotting).
However, more studies will be needed to measure the effect in humans.
Bromelain is known for its anti-inflammatory, antithrombotic, antiplatelet and fibrinolytic (dissolving blood clots) properties.
In the past, studies have also shown that bromelain would reduce the risk of angina, act against hypertension and reduce the risk of coronary infarction. However, few clinical studies have been conducted in humans. Most were either in vitro studies or in vivo studies in animals.
Some studies have shown that thanks to its anti-inflammatory and analgesic properties, bromelain, which is very present in pineapple, may prove to be a safe alternative treatment for osteoarthritis.
What does pineapple contain?
The pineapple plant and its fruit contain bromelain, an enzyme that would have multiple actions: anti-inflammatory, anti-tumor, anti-edematous, in addition to digestion and improve circulatory and cardiovascular systems.
These effects were observed in humans, animals and in vitro, following the ingestion of bromelain extracts (from pineapples or synthesized).
The beneficial effects of bromelain extracts were observed at doses of 160 mg per day, but more markedly at daily doses of 500 mg and more. According to empirical data, these doses correspond to 1 to 2 cups (from 250 ml to 500 ml) of fresh pineapple.
In fresh pineapple only. Bromelain is found in fresh pineapple, canned and cooked pineapples do not.
Polyphenols and flavonoids, phenolic compounds present in plants, possess antioxidant properties. They can help prevent the emergence of several diseases (cancers, cardiovascular diseases, and various chronic diseases) by neutralizing free radicals in the body.
Phenolic compounds have been identified in pineapples, such as gallic acid, but this fruit is not particularly distinguished, compared to other exotic fruits (lychee, mango, kaki, etc.).
The pineapple has a high antioxidant potential, but lower than a dozen other common fruits, such as strawberry, lemon, orange, apple, and grape. Moreover, the vitamin C content of pineapple would contribute to just over 30% of its antioxidant potential.
The consumption of pineapple causes the release of histamine into the body. This is also the case in other foods, including strawberry and tomato.
In some people, this can cause the development of benign reactions, such as urticaria. It is important to note that these reactions are not allergies, but rather food intolerance.
Stopping the consumption of the food causes the symptoms to stop. The real allergy to pineapple is rather rare, although cases have been observed. Cross reactions are also possible with latex and pollen.
People allergic to these two compounds may demonstrate hypersensitivity to pineapple (as well as to other fruits, such as kiwi and banana), and vice versa. People who are intolerant or allergic to pineapple should avoid consuming the fruit, but also take bromelain supplements.
It is recommended to consult an allergist to determine the cause of the reactions to certain foods and the precautions to be taken.
Choice and conservation
The perfume of a pineapple is a good indicator of its degree of maturity and its sugar content: it should be full and fruity, but not too pronounced, the probable sign of an early fermentation.
On the other hand, the color of the bark is not necessarily a good indication: a fruit with green bark can be perfectly ripe.
Evenly sized, choose the heaviest fruits, whose leaves are firm, fresh and of a beautiful dark green. Avoid those that look old, dried, damaged or have soft parts or those whose leaves are brown.
It is best to avoid canned fruits, drinks, and juices when they contain large amounts of added sugar.
Fridge. Pineapple can be stored for 1 or 2 days at room temperature, but it is best to keep it in the refrigerator (up to 4 or 5 days). Put it in a perforated plastic bag in the fruit and vegetable bin. Peeled and cut into pieces, it will keep for a few days in an airtight container. The pieces of water must be covered.
Freezer. It is peeled, the heart removed and cut into pieces or mashed and placed in freezer bags. It is recommended not to freeze for more than 3 months, at the risk of losing its flavor.
