Top 10 Healthiest Fruits us..

Strawberries
In addition to being consumed fresh, strawberries can be frozen, made into preserves, as well as dried and used in such things as cereal bars. Strawberries are a popular addition to dairy products, as in strawberry-flavored ice cream, milkshakes, smoothies, and yogurts. Strawberries and Cream is a popular dessert, famously consumed at Wimbledon. Strawberry pie is also popular.

Strawberry pigment extract can be used as a natural acid/base indicator due to the different color of the conjugate acid and conjugate base of the pigment.


Apples
Research suggests that apples may reduce the risk of colon cancer, prostate cancer and lung cancer. Compared to many other fruits and vegetables, apples contain relatively low amounts of vitamin C, but are a rich source of other antioxidant compounds. The fiber content, while less than in most other fruits, helps regulate bowel movements and may thus reduce the risk of colon cancer.

They may also help with heart disease, weight loss, and controlling cholesterol. The fiber contained in apples reduces cholesterol by preventing reabsorption, and (like most fruits and vegetables) they are bulky for their caloric content.

There is evidence that in vitro apples possess phenolic compounds which may be cancer-protective and demonstrate antioxidant activity. The predominant phenolic phytochemicals in apples are quercetin, epicatechin, and procyanidin B2.

Apple juice concentrate has been found to increase the production of the neurotransmitter acetylcholine in mice, providing a potential mechanism for the "prevention of the decline in cognitive performance that accompanies dietary and genetic deficiencies and aging." Other studies have shown an "alleviat[ion of] oxidative damage and cognitive decline" in mice after the administration of apple juice.

Researchers at the Chinese University of Hong Kong discovered that fruit flies who were fed an apple extract lived 10 percent longer than other flies who were fed a normal diet.

However, apple seeds are mildly poisonous, containing a small amount of amygdalin, a cyanogenic glycoside; it usually is not enough to be dangerous to humans, but can deter birds.

Bananas
Bananas contain moderate amounts of vitamin B6, vitamin C, manganese and potassium.

Along with other fruits and vegetables, consumption of bananas may be associated with a reduced risk of colorectal cancer and in women, breast cancer and renal cell carcinoma.

Banana ingestion may affect dopamine production in people deficient in the amino acid tyrosine, a dopamine precursor present in bananas.

In India, juice is extracted from the corm and used as a home remedy for jaundice, sometimes with the addition of honey, and for kidney stones.
Individuals with a latex allergy may experience a reaction to bananas

Blackberries
Blackberries contain numerous large seeds that are not always preferred by consumers. The seeds contain some oil which is rich in omega-3 (alpha-linolenic acid) and -6 fats (linoleic acid), as well as some protein, dietary fiber, carotenoids, ellagitannins and ellagic acid.


Cherries
Cherries contain anthocyanins, the red pigment in berries. Cherry anthocyanins have been shown to reduce pain and inflammation in rats. Anthocyanins are also potent antioxidants under active research for a variety of potential health benefits. According to a study funded by the Cherry Marketing Institute presented at the Experimental Biology 2008 meeting in San Diego, rats that received whole tart cherry powder mixed into a high-fat diet did not gain as much weight or build up as much body fat, and their blood showed much lower levels of inflammation indicators that have been linked to heart disease and diabetes. In addition, they had significantly lower blood levels of cholesterol and triglycerides than the other rats.


Blueberries
Especially in wild species, blueberries contain anthocyanins, other antioxidant pigments and various phytochemicals possibly having a role in reducing risks of some diseases, including inflammation and certain cancers.

Mangoes
 A single mango has enough beta-carotene to cover your RDA for vitamin A while racking up 57 mg of vitamin C.
Oranges
One orange provides an impressive 50 mg to 70 mg of vitamin C, 40 mcg of folic acid and 52 mg of calcium.


Purple grapes
Offer three heart-guarding compounds: flavonoids, anthocyanins and resveratrol (green grapes are not rich in them)


Raspberries
Raspberries contain significant amounts of polyphenol antioxidants such as anthocyanin pigments linked to potential health protection against several human diseases.
Teeming with 8 g of fiber per cup, they also boast vitamin C, ellagic acid and anthocyanins.
