NOT ALL APPLES ARE CREATED EQUAL
Different apple species contain varying levels of nutritive benefits. Some of the most common are listed below.
PINK LADY APPLE

According to Professor Jonathan Hodgson: “Flavonoid-rich [FRUIT] improve blood vessel relaxation and enhance nitric oxide status.” The ability for blood vessels to relax may play an important part in preventing high blood pressure and heart disease.
RED DELICIOUS APPLE
The Red Delicious is perhaps one of the most popular varieties in the United States with its luscious flesh and deep red skin. According to a publication by the Journal of Agricultural and Food Chemistry, the phenolic compounds found in the Red Delicious and Northern Spy have the potential to provide additional antioxidant benefits to the consumer. The apple peels contain the highest levels of phenolic compounds, which is another very good reason to eat the entire apple rather than skinning them first.
GRANNY SMITH APPLE
The Granny Smith is known for its ability to help with losing weight. An imbalance of good bacteria in your colon can cause inflammation or diabetes in certain susceptible people.

HEALTH BENEFITS OF APPLE THAT MIGHT SURPRISE YOU
Apples are a veritable powerhouse of nutrition and are packed with a wide array of health benefiting substances. One of the top health benefits of the fruit is their extremely high level of antioxidants.

Antioxidants are found in very high levels in all fruits and vegetables.
The importance of consuming a balanced antioxidant profile cannot be overstressed as an imbalanced consumption can lead to its own health risks. Obtaining your antioxidants from natural sources such as fruits and dark green leafy vegetables is the safest way to ensure a balanced nutrient intake.
Free radicals are unstable molecules that the body produces in response to environmental or physical stressors. Antioxidants are also referred to as free radical scavengers. Antioxidants provide a natural defense against free radical damage, also known as oxidative stress. Reasons for oxidative stress include:
Inflammation and injury
Excessive consumption of refined foods, trans fats, and artificial ingredients
Chemical exposure (e.g. drugs, pesticides, solvents)
The health benefits of this fruit are varied and possibly too numerous to count as science continues to find out more and more information. However, here are 15 surprising health benefits of eating this fruit that will have you eating one or more of them a day.

Another study revealed that apple juice has the potential to increase production of acetylcholine, an essential neurotransmitter that is responsible for memory.
3 HELP PREVENT CANCER
The consumption of flavonoid-rich foods can help reduce the risk of certain types of cancer by up to 23 percent. Apple peels contain a specific compound known as triterpenoids that have potent activity against abnormal cell growth in the liver, colon, and breast. Extracts from the whole fruit were observed to have reduced the size and number of mammary tumors in rats. According to the National Library of Medicine National Institutes of Health, consuming high levels of fiber can help reduce the risk of developing cancer.

The polyphenols present in the fruit helps lower glucose absorption in the digestive tract and stimulates the pancreas to release insulin. Also, these polyphenols help stimulate insulin receptors on the body’s cells to speed up the elimination of excess sugar from the bloodstream.
5. GALLSTONE PREVENTION
Gallstones are formed by presences of digestive fluid deposits in your gallbladder, a small organ located just below your liver. The gallbladder is responsible for releasing bile into your small intestine to help with digestion of fats and proteins. Gallstones can be as small as a grain of salt as small or as large as a small apple.  Gallstone formation can occur from:
Excess cholesterol. When the liver excretes more cholesterol than the bile can dissolve, it can crystalize and eventually form into stones.
Excess bilirubin. Bilirubin is produced by the liver in order break down old red blood cells. When too much bilirubin is produced as a result of liver disease, infection or blood disorders, gallstones can form.
IMPROPER GALLBLADDER FUNCTION
Improper gallbladder function. When the gallbladder fails to empty properly, the bile present can become concentrated, leading to the formation of gallstones.
The high fiber content of fruits eaten with skins on can help prevent the formation of gallstones. Therefore, you enjoy balanced cholesterol levels and a healthier weight.
