Nutritional information for apples

Apples deserve being called "nutritional powerhouses". They contain the following important nutrients:

• Vitamin C - a powerful natural antioxidant capable of blocking some of the damage caused by free radicals, as well as boosting the body's resistance against infectious agents, according to the University of Maryland Medical Center.¹
• B-complex vitamins (riboflavin, thiamin, and vitamin B-6) - these vitamins are key in maintaining red blood cells and the nervous system in good health.
• Dietary fiber - the British National Health Service² says that a diet high in fiber can help prevent the development of certain diseases and may help prevent the amount of bad cholesterol in your blood from rising.
• Phytonutrients - apples are rich in flavonoids and polyphenolics. These phytonutrients help protect the body from the detrimental effects of free radicals.³
• Minerals such as calcium, potassium, and phosphorus.

Health benefits of apples

A collection of research studies suggests that apples may well be one of the best foods people should add to their diet.
Apples can potentially:

Promote good neurological health

Apples are good for neurological health. The fruit contains an antioxidant called "quercetin" which reduces cellular death caused by oxidation and inflammation of neurons, according to research conducted by G. Bureau and M. Martinoli at the University of Quebec.

Prevent dementia

Researchers at Cornell University conducted a study, published in the Journal of Food Science, which found evidence to suggest that apples may help "protect neuron cells against oxidative stress-induced neurotoxicity", which could reduce the risk of developing neurodegenerative disorders such as Alzheimer's disease.

Reduce your risk of stroke

A study involving 9,208 men and women showed that those who ate the most apples over a 28-year period had the lowest risk for stroke. The researchers concluded "the results suggest that the intake of apples is related to a decreased risk of thrombotic stroke."⁴

Lower levels of bad cholesterol

A group of researchers at The Florida State University stated that apples really are a "miracle fruit". They found that older women who ate apples everyday had 23% less bad cholesterol (LDL) and 4% more good cholesterol (HDL) after just six months.

Reduce the risk of diabetes

Apples could also help lower your risk of diabetes. A study involving 187,382 people found that people who ate three servings per week of apples, grapes, raisins, blueberries or pears had a 7% lower risk of developing type 2 diabetes compared to those who did not.

Ward off breast cancer

There is growing evidence suggesting that an apple a day may help prevent breast cancer, according to a series of studies conducted by prominent Cornell researcher Rui Hai Liu.

Liu said her research adds to "the growing evidence that increased consumption of fruits and vegetables, including apples, would provide consumers with more phenolics, which are proving to have important health benefits. I would encourage consumers to eat more and a wide variety of fruits and vegetables daily."

Risks and precautions

No serious side effects are linked to apple consumption.

Apple seeds contain contain cyanide, a powerful poison. Eating too many apple seeds can potentially be fatal. Apple seeds should not be consumed.

In addition, because apples are fairly acidic, they could be up to four times more damaging to teeth than carbonated drinks, according to a study led by Professor David Bartlett at the King's Dental Institute.
 
Professor Bartlett said that "snacking on acidic foods throughout the day is the most damaging, whilst eating them at meal times is much safer. It's not what you eat it's how you eat it - an apple a day is good, but taking all day to eat the apple can damage teeth."

Apples - three frequently asked questions

Should I eat the apple peel? -

Most of the fiber and antioxidants are in the peel, says Dianne Hyson, Ph.D., R.D., a research dietitian at UC Davis in the Department of Internal Medicine.

What about pesticides on the peel? - Dr. Hyson says "Despite public misperceptions, laboratories have consistently found very low levels - if any - of pesticide residues on the skin of apples."

I have type 2 diabetes, can I eat apples? -

According to the American Diabetes Association, "Apples are a nutritious food and you can still eat them even if you have diabetes." The Association reminds people to eat the peel and advises on buying small apples (2.5 inches in diameter).
