Pineapples are actually not just one fruit but a composite of many flowers whose individual fruitlets fuse together around a central core. Each fruitlet can be identified by an ‘eye,’ the rough spiny marking on the pineapple’s surface.
Pineapples have a wide cylindrical shape, a scaly green, brown or yellow skin and a regal crown of spiny, blue-green leaves. The fibrous flesh of pineapple is yellow in color and has a vibrant tropical flavor that balances the tastes of sweet and tart. The area closer to the base of the fruit has more sugar content and therefore a sweeter taste and more tender texture.
Health Benefits of Pineapples
It lessens risk of hypertension. Hypertension occurs when too much force is exerted on the artery walls while the blood circulates. One of the best ways to combat this is to infuse a high amount of potassium plus a small amount of sodium in your diet to lower blood pressure. Pineapples are the perfect for hypertension because a cup of pineapple contains about 1 mg of sodium and 195 mg of potassium.
It helps you lose weight! Eating pineapple can highly cut down your sweet cravings because of its natural sweetness, saving you from a lot of sugar-induced calories. Incorporating a lot of pineapple in your meals will also help a lot in weight loss because pineapples can make you feel full without giving you an ounce of fat.
It maintains good eye health. Time and again, studies have found that pineapples protect against age-related eye problems because it is rich in antioxidants.
It fights a lot of diseases, being rich in Vitamin C. Pineapples are known to be a very good source of vitamin C, which protects our bodies from free radicals that attack our healthy cells. Lots of free radicals in the body can lead to major diseases like heart disease, diabetes, and various cancers. Vitamin C is considered the most important water-soluble anti-oxidant that fights against disease-inducing substances within the body. It is also an excellent fighter against flu and a great enhancer of the immune system.
It prevents plaque and keeps teeth healthy. Another benefit of the high amount of vitamin C in pineapples is that it prevents formation of plaque and gum diseases.
It cures constipation and irregular bowel movement. Pineapple is rich in fiber, making it effective in curing constipation and irregular bowel movement.
It keeps your skin beautiful! Pineapple contains enzymes that make skin elastic, improve skin hydration, and remove damaged and dead cells. Thus, it helps us achieve a clear and glowing complexion. The enzymes in pineapples also fight free-radical damage and can reduce age spots and fine lines.
Potential Anti-Inflammatory and Digestive Benefits
Bromelain is a complex mixture of substances that can be extracted from the stem and core fruit of the pineapple. Among dozens of components known to exist in this crude extract, the best studied components are a group of protein-digesting enzymes (called cysteine proteinases). Originally, researchers believed that these enzymes provided the key health benefits found in bromelain, a popular dietary supplement containing these pineapple extracts. In addition, researchers believed that these benefits were primarily limited to help with digestion in the intestinal tract. However, further studies have shown that bromelain has a wide variety of health benefits, and that many of these benefits may not be related to the different enzymes found in this extract. Excessive inflammation, excessive coagulation of the blood, and certain types of tumor growth may all be reduced by therapeutic doses of bromelain when taken as a dietary supplement. Studies are not available, however, to show these same potential benefits in relationship to normal intake of pineapple within a normal meal plan.
Bromelain extracts can be obtained from both the fruit core and stems of pineapple. Potentially important chemical differences appear to exist between extracts obtained from the stem versus the core fruit. However, the practical relevance of these differences is not presently understood. Most of the laboratory research on bromelain has been conducted using stem-based extracts, however.
Although healthcare practitioners have reported improved digestion in their patients with an increase in pineapple as their “fruit of choice” within a meal plan, we haven’t seen published studies that document specific changes in digestion following consumption of the fruit (versus supplementation with the purified extract. However, we suspect that the core fruit will eventually turn out to show some unique health-supportive properties, including possible digestion-related and anti-inflammatory benefits.
Antioxidant Protection and Immune Support
Vitamin C is the body’s primary water-soluble antioxidant, defending all aqueous areas of the body against free radicals that attack and damage normal cells. Free radicals have been shown to promote the artery plaque build-up of atherosclerosis and diabetic heart disease, cause the airway spasm that leads to asthma attacks, damage the cells of the colon so they become colon cancer cells, and contribute to the joint pain and disability seen in osteoarthritis and rheumatoid arthritis. This would explain why diets rich in vitamin C have been shown to be useful for preventing or reducing the severity of all of these conditions. In addition, vitamin C is vital for the proper function of the immune system, making it a nutrient to turn to for the prevention of recurrent ear infections, colds, and flu.
Manganese and Thiamin (Vitamin B1) for Energy Production and Antioxidant Defenses
Pineapple is an excellent source the trace mineral manganese, which is an essential cofactor in a number of enzymes important in energy production and antioxidant defenses. For example, the key oxidative enzyme superoxide dismutase, which disarms free radicals produced within the mitochondria (the energy production factories within our cells), requires manganese. In addition to manganese, pineapple is a good source of thiamin, a B vitamin that acts as a cofactor in enzymatic reactions central to energy production.
Protection against Macular Degeneration
Your mother may have told you carrots would keep your eyes bright as a child, but as an adult, it looks like fruit is even more important for keeping your sight. Data reported in a study published in the Archives of Ophthalmology indicates that eating 3 or more servings of fruit per day may lower your risk of age-related macular degeneration (ARMD), the primary cause of vision loss in older adults, by 36%, compared to persons who consume less than 1.5 servings of fruit daily.
In this study, which involved over 110,000 women and men, researchers evaluated the effect of study participants’ consumption of fruits; vegetables; the antioxidant vitamins A, C, and E; and carotenoids on the development of early ARMD or neovascular ARMD, a more severe form of the illness associated with vision loss. While, surprisingly, intakes of vegetables, antioxidant vitamins and carotenoids were not strongly related to incidence of either form of ARMD, fruit intake was definitely protective against the severe form of this vision-destroying disease. Three servings of fruit may sound like a lot to eat each day, but pineapple can help you reach this goal. Add fresh pineapple to your morning smoothie, lunch time yogurt, any fruit and most vegetable salads. For example, try adding chunks of pineapple to your next coleslaw or carrot salad.
