The proverb "An apple a day keeps the doctor away” helps us to understand how important the apple is in our daily life. Compared to many other fruits and vegetables, apples contain relatively low amounts of vitamin C, but are a rich source of other antioxidant compounds. They may also help with heart disease, weight loss, and controlling cholesterol. Apple is a rich source of flavonoid and polyphenols both are powerful antioxidant.
We can just look out the detailed health benefits of Apple one by one.
1. Regulates Blood Sugar:
Apples are a good source of soluble fiber, especially pectin, which helps control insulin levels by slowing the release of sugar into your bloodstream. Pectin also helps reduce cholesterol levels by lowering insulin secretion. Getting sugar out of our bloodstream often requires the help of insulin, a hormone produced by the beta cells of our pancreas. By telling the beta cells of our pancreas to produce more insulin, the poly phenols found in apple can help us clear more sugar from our blood and keep our blood sugar level in better balance.
2. Lower the Blood Cholesterol level:
The fiber contained in apples reduces cholesterol by preventing re-absorption, and (like most fruits and vegetables) they are bulky for their caloric content. The pectin in apples lowers LDL ("bad") cholesterol. Total cholesterol and LDL-cholesterol are both decreased through regular intake of apples. The strong antioxidant composition of apples provides us with protection from possible oxidation of fats (called lipid per oxidation), including fats found in the bloodstream (like triglycerides) or fats found in the membranes of cells linking our blood vessels. Decreased lipid per oxidation is a key factor in lowering risk of many chronic heart problems. Recent research has shown that the quercetin content of apples also provides our cardiovascular system with anti-inflammatory benefits.
One recent study shows that children with asthma who drank apple juice on a daily basis suffered from less wheezing than children who drank apple juice only once per month. Another study showed that children born to women who eat a lot of apples during pregnancy have lower rates of asthma than children whose mothers ate few apples. Multiple studies have shown apple intake to be associated with decreased risk of asthma. However, in some cases, the study findings have been even stronger. In one study, apples showed better risk reduction for asthma than total fruit-plus-vegetable intake combined! Like the anti-cancer benefits of apples, apples' anti-asthma benefits are definitely associated with the antioxidant and anti-inflammatory nutrients found in this fruit. However, there is very likely to be something else going on as well since apples appear to be a truly standout fruit in this regard.
4. Anti-cancer Benefits:
Research suggests that apples may reduce the risk of colon cancer, prostate cancer, breast cancer and lung cancer. The fiber content, while less than in most other fruits, helps regulate bowel movements and may thus reduce the risk of colon cancer.
5. Alzheimer's disease:
Preliminary health benefits of apples have also been established for several age-related health problems, including macular degeneration of the eye and neurodegenerative problems, including Alzheimer's disease. A study on mice at Cornell University found that the quercetin in apples may protect brain cells from the kind of free radical damage that may lead to Alzheimer's disease.
