Apples 101 Re-Search – 9 Health Facts

Apple trees are grown worldwide and are the most extensively grown species in the genus Malus. The tree originated in Central Asia, where its wild relative, Malus sieversii, is still seen today. Apples have been grown for thousands of years in Asia and Europe and were returned to North America by European colonists. Apples have mythological and religious significance in various cultures, including Norse, Greek, and European Christian traditions.

Apple Facts


Source Apple Statistics:
USDA National Agricultural Statistics Service
United States Apple Association

Apples & Weight Loss

One 10-week study in 50 overweight women shows that participants who consumed apples dropped an average of 2 pounds (1 kg) and consume fewer calories overall, compared to those who consumed oat cookies with a similar amount of calorie and fiber content.(source)

Researchers find that apples are more filling because they are less energy-dense, yet still provide enough fiber and volume.

Another research in obese mice discovered that those given a supplement of ground apples and apple juice concentrate dropped more weight and produced lower levels of “bad” LDL cholesterol, triglycerides, and total cholesterol than the control group. (source)

Apples & Heart Health

Apples have been connected to a lower risk of heart disorder. (Source)
One important reason may be that apples contain soluble fiber — the fiber that can help decrease your blood cholesterol levels. Apples also contain polyphenols, which possess antioxidant effects. Several of these are concentrated in the peel of the apple. One of those polyphenols is the flavonoid epicatechin, which may decrease blood pressure.

A review of studies discovered that high consumptions of flavonoids were connected to a 20% lower risk of stroke. (Source)

Flavonoids can improve and prevent heart illness by lowering blood pressure and reducing “bad” LDL cholesterol and helping as antioxidants. (Source) For every 25 grams — about 1/5 cup of apple slices — eaten, the risk of stroke lowered by 9%. (Source)

 

Apples & Risk of Diabetes

Numerous studies have linked consuming apples to a lower risk of type 2 diabetes.(Source)

In one extensive study, consuming an apple a day was connected to a 28% lower risk of type 2 diabetes, compared to not consuming any apples. Even consuming just a few apples per week produced a similarly protective effect.(Source)

Apples & Prebiotic Effects That Promote Good Gut Bacteria

Apples have pectin, a kind of fiber that plays as a prebiotic. This means it supports good and healthy bacteria in your gut.

The small intestine doesn’t absorb fiber during digestion. Instead, it continues to your colon, where it can promote the growth of good bacteria. It also changes into other essential compounds that circulate back through your body (Source).

New research implies that this may be the cause behind some of the protecting effects of apples against obesity, heart disease, and type 2 diabetes.

Apples & Compounds That Can Help Fight Asthma

An extended study in more than 68,000 women discovered that those who consumed the most apples had the lowest risk of asthma. Consuming about 15% of a large apple per day was connected to a 10% lower risk of Asthma (Source).

Apple skin holds the flavonoid quercetin, which can improve and regulate the immune system to reduce inflammation. These are two methods in which it may affect asthma and allergic responses (Source).

Apples & Bone Health

Researchers find that the antioxidant and anti-inflammatory compounds in fruit may help increase bone density and strength.

Few studies reveal that apples, specifically, may undoubtedly affect bone health (Source).

In one research, women had a meal that either included fresh apples, peeled apples, applesauce, or no apple products. Those who consumed apples lost less calcium from their bodies than the control group (Source).

Apples & Protection Against Stomach Injury From NSAIDs

The group of painkillers known as nonsteroidal anti-inflammatory drugs (NSAIDs) can damage the lining of your stomach.

Research in test tubes and rats discovered that freeze-dried apple extract helped to protect stomach cells from damage due to NSAIDs (Source).

Two plant components in apples — chlorogenic acid and catechin — are considered to be especially helpful (Source).

Still, further study in humans is required to confirm these results.

Apples & Brain Protection

In animal studies, juice concentrate decreased harmful reactive oxygen species (ROS) in brain tissue and minimized a mental decline (Source).

Apple juice may help protect acetylcholine, a neurotransmitter that can decline with age. Low levels of acetylcholine are connected to Alzheimer’s disease (Source).

Furthermore, researchers, who fed elderly rats whole apples discovered that a marker of the rats’ memory was restored to the level of younger rats (Source).

That said, whole apples hold the same compounds as apple juice — and it is always a better choice to eat your fruit whole.
