Is apple a fruit with overrated nutritional value?
"An apple a day keeps the doctor away."
This was actually an advertisement used to save the apple industry during the Great Prohibition in the United States in the 1930s.
So, is "an apple a day" a commercial conspiracy, or is it really beneficial to humans?
Is apple an ordinary fruit that is overrated?
Comparison of common nutrients
Fruit is an important part of a balanced diet. Fresh fruit is an important source of nutrients such as vitamin C, beta-carotene, potassium, dietary fiber, and a variety of phytochemicals.
Although the content of vitamins, minerals, and dietary fiber in apples is not high, its advantage is that it is rich in antioxidants.
Comparison of antioxidant capacity.
A study compared cranberries, apples, grapes, strawberries, peaches, lemons, pears, bananas, oranges, pineapples, and grapefruits, which are relatively common antioxidant fruits, and found that apples have very strong antioxidant capacity.
Although it is slightly worse than the first cranberry, it is much more common than fresh cranberries!
▲The study found that cranberries have the highest total antioxidant content, followed by apples, red grapes, strawberries, peaches, lemons, pears, bananas, oranges, grapefruits and pineapples.
The study believes that the super antioxidant capacity of apples mainly comes from its rich and comprehensive phenols, such as chlorogenic acid, quercetin, catechins, proanthocyanidins, etc.
This strong antioxidant ingredient has many benefits for health.
A study showed that apples are rich in phenolic anti-inflammatory bioactive substances, which can reduce the risk of cardiovascular disease.
A test comparing the effects of apples, pears and peaches on rats' blood lipids found that the dietary fiber content of these three fruits was not much different, but apples had a greater ability to lower cholesterol and enhance plasma antioxidants. This is related to the fact that apples contain more phenolic antioxidants.
A study that investigated the diet and lifestyle of nearly 600 asthmatics and 900 non-asthmatics showed that apple intake was strongly negatively correlated with asthma.
In addition, studies have found that eating apples before meals can help lose weight: eating a small apple before eating can reduce food intake by 200kcal and help control weight.
The reason is that apples are large, full of weight, rich in water and dietary fiber, which can bring satisfaction to the stomach.
In this case, drinking more water and eating vegetables first when eating can also have the same effect!
Different flesh
In addition to the white flesh apples we often eat, there are now new varieties of red flesh apples.
▲ Studies have found that the total amount of antioxidant components in red flesh apples is higher than that in white flesh apples
Studies have shown that the chlorogenic acid, anthocyanin, and organic acid contained in the peel and flesh of red flesh apples are higher than those of white flesh apples.
And these substances are all good antioxidants.
Judging from the color of the flesh, the nutritional value of red flesh apples may be higher.
Apple peel is a valuable source of antioxidant components. Studies have found that the total phenolic content in apple peel is the highest, the total amount of antioxidant components in the flesh is much lower than that in the peel, and quercetin is even only found in the peel.
A study found that the antioxidant capacity of the peel of a medium-sized Idared apple is equivalent to 820 mg of vitamin C.
Apple Cider Vinegar Powder otherwise known as cider vinegar or ACV, is a type of vinegar made from cider or apple must and has a pale to medium amrber color. Unpasteurized or organic ACV contains mother of vinegar, which has a cobweb-like appearance and can make the vinegar look slightly congealed.
ACV is used in salad dressings, marinades, vinaigrettes, food preservatives, and chutneys, among other things. It is made by crushing apples and squeezing out the liquid. Bacteria and Yeast are added to the liquid to start the alcoholic fermentation process, and the sugars are turned into alcohol. In a second fermentation process, the alcohol is converted into vinegar by acetic acid-forming bacteria (acetobacter). Acetic acid and malic acid give vinegar its sour taste.
