Apple - All about it

The apple is a fleshy fruit from the apple tree. It is in the species Malus domestica in the rose family Rosaceae. The apple is one of the most grown tree fruits.

The apple tree came from Central Asia. Its wild ancestor is still there today. There are more than 7,500 kinds of different apple trees.

At least 55 million tons of apples were grown around in the world in 2005. All together, they cost about $10 billion. China produced about 35% of the world's apples. The United States produces more than 7.5% of the apples around the world. This makes it the second greatest producer. Iran is third, after which comes Turkey, Russia, Italy and India.


Botanical information

The apple has a small, leaf-shedding tree that grows up to 3 to 12 metres (9.8 to 39 ft) tall. The apple tree has a broad crown with thick twigs. The leaves are alternately arranged simple ovals. They are 5 to 12 centimetres long and 3–6 centimetres (1.2–2.4 in) wide. It has a sharp top with a soft underside. Blossoms come out in spring at the same time that the leaves begin to bud. The flowers are white. They also have a slightly pink color. They are five petaled, and 2.5 to 3.5 centimetres (0.98 to 1.4 in) in diameter. The fruit matures in autumn. It is usually 5 to 9 centimetres (2.0 to 3.5 in) in diameter. There are five carpels arranged in a star in the middle of the fruit. Every carpel has one to three seeds.




Apple - 15 Benefits

1. Get whiter, healthier teeth
An apple won’t replace your toothbrush, but biting and chewing an apple stimulates the production of saliva in your mouth, reducing tooth decay by lowering the levels of bacteria.

2. Avoid Alzheimer’s
A new study performed on mice shows that drinking apple juice could keep Alzheimer’s away and fight the effects of aging on the brain. Mice in the study that were fed an apple-enhanced diet showed higher levels of the neurotransmitter acetylcholine and did better in maze tests than those on a regular diet.

3. Protect against Parkinson’s
Research has shown that people who eat fruits and other high-fibre foods gain a certain amount of protection against Parkinson’s, a disease characterized by a breakdown of the brain’s dopamine-producing nerve cells. Scientists have linked this to the free radical-fighting power of the antioxidants contained therein.

4. Curb all sorts of cancers
Scientists from the American Association for Cancer Research, among others, agree that the consumption of flavonol-rich apples could help reduce your risk of developing pancreatic cancer by up to 23 per cent. Researchers at Cornell University have identified several compounds—triterpenoids—in apple peel that have potent anti-growth activities against cancer cells in the liver, colon and breast. Their earlier research found that extracts from whole apples can reduce the number and size of mammary tumours in rats. Meanwhile, the National Cancer Institute in the U.S. has recommended a high fibre intake to reduce the risk of colorectal cancer.

6 reasons to eat more apples
Women who eat at least one apple a day are 28 percent less likely to develop type 2 diabetes than those who don’t eat apples. Apples are loaded with soluble fibre, the key to blunting blood sugar swings.

6. Reduce cholesterol
The soluble fibre found in apples binds with fats in the intestine, which translates into lower cholesterol levels and a healthier you.

7. Get a healthier heart
An extensive body of research has linked high soluble fibre intake with a slower buildup of cholesterol-rich plaque in your arteries. The phenolic compound found in apple skins also prevents the cholesterol that gets into your system from solidifying on your artery walls. When plaque builds inside your arteries, it reduces blood flow to your heart, leading to coronary artery disease.

8. Prevent gallstones
Gallstones form when there’s too much cholesterol in your bile for it to remain as a liquid, so it solidifies. They are particularly prevalent in the obese. To prevent gallstones, doctors recommend a diet high in fibre to help you control your weight and cholesterol levels.

9. Beat diarrhea and constipation
Whether you can’t go to the bathroom or you just can’t stop, fibre found in apples can help. Fibre can either pull water out of your colon to keep things moving along when you’re backed up, or absorb excess water from your stool to slow your bowels down.

10. Neutralize irritable bowel syndrome
Irritable bowel syndrome is characterized by constipation, diarrhea, and abdominal pain and bloating. To control these symptoms doctors recommend staying away from dairy and fatty foods while including a high intake of fibre in your diet.

11. Avert hemorrhoids
Hemorrhoids are a swollen vein in the anal canal and while not life threatening, these veins can be very painful. They are caused by too much pressure in the pelvic and rectal areas. Part and parcel with controlling constipation, fibre can prevent you from straining too much when going to the bathroom and thereby help alleviate hemorrhoids.

12. Control your weight
Many health problems are associated with being overweight, among them heart disease, stroke, high blood pressure, type 2 diabetes and sleep apnea. To manage your weight and improve your overall health, doctors recommend a diet rich in fibre. Foods high in fibre will fill you up without costing you too many calories.

13. Detoxify your liver
We’re constantly consuming toxins, whether it is from drinks or food, and your liver is responsible for clearing these toxins out of your body. Many doctors are skeptical of fad detox diets, saying they have the potential to do more harm than good. Luckily, one of the best—and easiest—things you can eat to help detoxify your liver is fruits—like apples.

14. Boost your immune system
Red apples contain an antioxidant called quercetin. Recent studies have found that quercetin can help boost and fortify your immune system, especially when you're stressed out.

15. Prevent cataracts
Though past studies have been divided on the issue, recent long-term studies suggest that people who have a diet rich in fruits that contain antioxidants—like apples—are 10 to 15 per cent less likely to develop cataracts.

Selection and Storage

Fresh apples are readily available in the stores all around the season. Choose fresh, bright, firm textured apples with rich flavor. Avoid fruits with pressure marks over their surface as they indicate underlying mottled of pulp.

Fresh apples can be kept at room temperature for few days and stored inside the refrigerator for two to three weeks. Wash them in clean running cold water before use to remove any surface dust and pesticide/fungicide residues.
