Apple cultivation is widespread in temperate regions on all continents. Due to their pleasant taste, versatility, and health benefits, they have long held a significant share in human nutrition. One small serving of apple (100 grams) contains approximately: 51 kcal of energy, 0.6 grams of protein, 0.5 grams of fat, 11.6 grams of carbohydrates, 2.5 grams of dietary fiber, 100 mg of potassium, 6 mg of vitamin C. Although apples are not classified as “superfoods,” the natural dietary fiber and bioactive compounds they contain allow this fruit to be categorized as a functional food. The main mass of these valuable substances is concentrated in the peel, so maximum benefit is achieved when consuming the fruits whole. Nevertheless, apples may not be recommended for certain categories of people. “Apples contain natural salicylates—compounds capable of triggering an allergic reaction in some people (e.g., skin rash or swelling). People with sensitive digestive systems are often inconvenienced by the tough fiber found in the peel of raw apples. In such cases, it is preferable to opt for baked apples.” Gastroenterologist, General Practitioner at Medscan/Hadassah Clinic Heat treatment leads to the partial destruction of some vitamins, such as ascorbic acid (vitamin C), however, the coarse fiber softens, and pectin is retained and can even become concentrated. As a result, the fruit is more easily absorbed by the body and remains beneficial for gut health and overall well-being. Positive Effects of Apple Consumption Support for Heart and Vascular Health Based on a meta-analysis combining the results of 16 scientific studies, specialists examined the correlation between the frequency of apple consumption and the risk of developing cardiovascular diseases. It was found that systematic inclusion of apples in the diet is generally associated with a reduced risk of death from cardiovascular diseases, ischemic heart disease, stroke, severe calcification of the abdominal aorta, as well as all-cause mortality. Research data indicates that apple consumption helps reduce metrics such as total cholesterol and low-density lipoprotein cholesterol (“bad” cholesterol), systolic blood pressure and pulse pressure, and the concentration of pro-inflammatory cytokines in blood plasma. Furthermore, apple consumption may contribute to an increase in the beneficial fraction of cholesterol. These favorable results were obtained based on a daily intake of 100 to 150 grams of apples, which is equivalent to approximately one to two small or medium-sized fruits. Potential Benefit for Cognitive Function Swedish scientists, observing two thousand people over six years, found that participants who adhered to the so-called Scandinavian diet demonstrated higher cognitive abilities. This dietary pattern, unlike diets rich in fatty and processed foods, involves a high content of vegetables, pears, peaches, and apples. Another study revealed that low consumption of flavonoid polymers, characteristic of apples, pears, and tea, doubles the likelihood of developing dementia. Aiding in Weight Management Apples can have a positive impact on weight loss, as an average fruit contains less than 100 calories and provides a high degree of satiety. Some scientific studies indicate a link between regular apple consumption and weight reduction. Prebiotics contained in apples, including polyphenols, serve as food for beneficial gut microflora, which potentially reduces risks associated with obesity. “Since apples possess both sweetness and the ability to induce satiety, they are an adequate choice for a healthy snack. It is critically important to consume them whole, without peeling the skin, as this is where most of the fiber and important antioxidant compounds are concentrated,” comments the expert. May Reduce the Risk of Type 2 Diabetes A small study conducted in Japan showed that eating an apple before a main meal results in a less pronounced subsequent rise in blood glucose levels after eating, which consequently reduces the risk of developing diabetes. This effect is most noticeable in individuals with impaired glucose tolerance. Another study demonstrates that apples and other fruits (pears, blueberries, grapes) reduce the likelihood of developing type 2 diabetes by approximately 7%. For Digestive Health Support and More: Optimal Time of Day for Eating Apples Cancer Prevention Including apples in the daily diet is associated with a reduced risk of developing certain types of cancer. For instance, one study recorded that systematic apple consumption reduces the risk of lung, bladder, breast, pancreatic, colon, pharyngeal, esophageal, ovarian, kidney, and prostate cancers. Researchers hypothesize that phytochemicals present in apples inhibit carcinogenesis and help slow the progression of tumors. Does One Apple a Day Really Reduce Doctor Visits? The English proverb, “An apple a day keeps the doctor away,” is widely known. Although there is no direct evidence proving this statement’s veracity, there are scientific works that indirectly support this idea. A group of scientists from the USA analyzed apple consumption patterns and the frequency of seeking medical attention among over 8,000 adults. Approximately 9% of this group reported eating one apple daily. After adjusting for demographic parameters and baseline health status, researchers found that those who ate an apple daily used slightly fewer prescription medications compared to those who did not consume apples. However, the frequency of doctor visits in both cohorts was roughly comparable. A European research group found that consuming two apples a day improves cardiovascular indicators in adults. Brazilian scientists concluded that eating three apples a day helps with weight loss and normalization of blood glucose levels in overweight women. However, it should be noted that both of these studies were conducted on a relatively small sample size—only 40 subjects. Main Conclusion Apples are an easily accessible and tasty fruit rich in fiber and antioxidants. Daily consumption supports cardiovascular health, leads to a reduction in “bad” cholesterol levels and blood pressure normalization, aids in weight management, may improve brain function, reduces the risk of developing type 2 diabetes and certain malignancies, and provides nutrition for beneficial gut microflora. Due to their low calorie content and high levels of beneficial elements, one apple daily can be a simple and effective component of a healthy eating regimen.
