1. How many calories are in an apple?

“How many calories are in an apple?” This is a question that many people, especially those following a diet, are interested in. According to data from the United States Department of Agriculture (USDA), a medium-sized apple, weighing about 100g, contains approximately 52 calories, 25 grams of carbohydrates, 4 grams of fiber, 0.5 grams of protein, and 19 grams of sugar. Notably, apples contain no fat.

In addition, apples are rich in water, vitamins, and minerals such as vitamin C, vitamin A, and sodium, which play a crucial role in maintaining the health and functioning of the body.

If you eat a whole apple with skin weighing 182g, you will provide your body with about 95 calories. When peeled, this calorie content reduces to about 72 calories. For green apples, a 100g apple provides 80-83 calories. If peeled, it’s only 60 – 63 calories.

However, the calorie content of each apple varies depending on the type of apple such as green apples, western apples, red apples, dried apples, apples with skin, peeled apples, etc. Therefore, when choosing apples to eat, you need to carefully consider the calorie content that suits your needs.

3. Does eating apples lead to weight gain?

The answer is, eating apples does not lead to weight gain. A medium-sized apple contains about 86% water and no fat. Foods rich in water, like apples, help reduce the number of calories consumed, while also creating a feeling of fullness faster. This effectively aids in weight control. Moreover, apples are packed with a substantial amount of fiber, making them an ideal choice for a daily weight loss diet. Thus, apples are not only delicious but also highly nutritious, helping you maintain optimal health and weight.

4. Benefits of eating apples

Apples are an excellent fruit for health and skin. Nutrition experts often recommend incorporating apples into our daily diet. Apples not only provide a wealth of important nutrients but also offer numerous health and skin benefits. Let’s explore the wonderful benefits that apples bring to us.

4.1. Good for the digestive system

Apples are a fruit rich in fiber, particularly pectin – a type of soluble fiber found in plant cell walls. Pectin has the ability to slow down digestion, absorb water, and form a gel-like substance, enhancing the feeling of fullness for a longer period. This makes apples a good choice for those who frequently encounter gastrointestinal issues, diarrhea, or want to lose weight.

The skin of the apple is a source of insoluble fiber. This component contains cellulose (the main structural component of plant cell walls), which helps improve constipation issues and maintain a healthy digestive system. Therefore, to maximize the benefits from apples, you should eat the whole fruit, including the skin. However, make sure you wash it thoroughly before eating.

4.2. Provides a high water content

Apples, with a water content of up to 86%, are not only delicious but also easy to digest, making them highly suitable for the dietary regimen of patients and those at high risk of dehydration. A study was conducted on children suffering from mild dehydration due to diarrhea and vomiting. The results showed that the group of children who drank apple juice reduced their need for intravenous fluid administration by 6.5% compared to the group drinking electrolyte solutions. This proves that apples are not just a tasty fruit but also offer numerous health benefits.

4.3. Enhances cardiovascular health

Apples are an excellent fruit for cardiovascular health. Here are some of the main benefits:

  • Antioxidants: According to a study at Ohio State University, eating an apple every day for four consecutive weeks can reduce the level of bad cholesterol, a major cause of arteriosclerosis. This demonstrates the powerful effect of polyphenols, a type of antioxidant abundant in apples.
  • Vitamin C: Apples contain a large amount of Vitamin C, which helps boost the immune system, stabilize BMI, lower blood pressure, and reduce C-reactive protein (a marker of inflammation). All these factors are directly related to cardiovascular health.
  • Free of saturated fats, sodium, and cholesterol: All three of these substances can harm the cardiovascular system if the body absorbs a large amount. In apples, saturated fats, sodium, and cholesterol do not exist.
  • Rich in Potassium: Potassium is a mineral that helps maintain stable blood pressure, preventing serious cardiovascular diseases.
  • Rich in Flavonoids: Anthocyanins, a type of flavonoid in apples, have the ability to reduce the risk of type 2 diabetes – a leading factor causing cardiovascular disease.

4.4. Apples aid in weight loss and weight control

Apples are an excellent choice for those who are following a weight loss diet. With their low calorie content but high in fiber and water, apples help enhance the feeling of fullness for a longer period, aiding in controlling overeating habits. Moreover, studies have shown that eating apples daily can help reduce lipid levels in the body, thereby reducing the risk of obesity. Thus, apples are not just a delicious fruit but also highly nutritious, helping you maintain optimal health and ideal weight.

4.5. Reduces the risk of diabetes

Apples, although they contain sugar, the majority of it is fructose, which does not significantly affect blood sugar levels. Moreover, apples are rich in fiber, which slows down digestion and sugar absorption, allowing sugar to be gradually transported into the blood, without causing negative impacts.

Polyphenols, a plant compound found in apples, help stabilize blood sugar and slow down carbohydrate digestion. On both the GI (glycemic index) and GL (glycemic load) scales, apples score relatively low, only minimally increasing blood sugar levels.

There are three main types of diabetes:

  • Type 1 Diabetes: This is an autoimmune disorder, where the pancreas does not produce enough insulin (a hormone that transports sugar from the blood to the body’s cells).
  • Type 2 Diabetes: In this case, the body increases the production of insulin-resistant cells and does not produce enough insulin to meet the body’s daily needs.
  • Gestational Diabetes.

Research shows that the habit of regularly eating apples can reduce insulin resistance, helping to stabilize blood sugar levels. In this, polyphenols play the most important role, mainly found in the peel, capable of stimulating the pancreas to release insulin and support cells in absorbing sugar.

The abundant antioxidant content of apples is also a factor that helps reduce the risk of chronic diseases, including diabetes. These components directly prevent some harmful chemical reactions to the body, including:

  • Quercetin: Slows down carbohydrate digestion, prevents sudden increases in blood sugar levels, harmful to health.
  • Chlorogenic Acid: Promotes the body to use sugar more effectively.
  • Phlorizin: Has the ability to slow down sugar absorption, helping to reduce blood sugar levels.

4.6. Prevents colorectal cancer

According to a study published in the International Journal of Molecular Sciences, complex carbohydrates in apples can help reduce the number, size, and growth rate of tumors. Furthermore, Oligosaccharides, an active substance in apples, can also inhibit the formation of new cancer cells.

Specifically, pectin and polyphenols, two important components in apples, have been proven to prevent the formation of malignant tumors in the colon. Their mode of operation is to stimulate the production of butyrate, a short-chain fatty acid (SCFA), directly related to gut health. Butyrate not only serves as an important nutrient for the intestinal epithelium but also enhances the protective ability of natural fiber, helping to prevent colon cancer. Thus, apples are not just a delicious fruit but also highly nutritious, helping to protect your health.

4.7. Eating apples for skin health

Apples are a fantastic fruit for your skin. Here are some ways that apples support your skin:

  • Nourishing for a smooth, radiant complexion: Apples are rich in Vitamins A, B, and C, which help eliminate excess oil, brighten the skin, and improve uneven skin tone. Additionally, the antioxidants in apples accelerate cell regeneration, maintaining a healthy and radiant skin.
  • Protecting skin from aging: Free radicals can break down collagen and elastin in the skin, leading to the formation of wrinkles, freckles, and age spots. Apples, with their abundant source of Vitamin C, are a powerful antioxidant, effectively controlling premature skin aging.
  • Hydrating the skin: Enhancing the hydration process (the process of retaining water) is the secret to maintaining soft and smooth skin. The high water content in apples is the ideal solution. In addition, the habit of eating apples daily also supports the treatment of acne, brown spots on the skin, moisturizing, enhancing resistance against ultraviolet rays, and improving dark circles. Thus, apples are not just a delicious fruit but also highly nutritious, helping to protect your skin.

5. How many apples should you eat per day for weight loss?

According to nutrition experts, consuming 1 – 2 apples each day can effectively support your weight loss process. Apples, rich in fiber and water, help create a long-lasting feeling of fullness without providing too many calories. However, the necessary quantity of apples can vary depending on each individual’s calorie needs and specific weight loss goals.

6. What should you be aware of when eating apples for weight loss?

Indeed, when consuming apples for weight loss, you should consider the following:

  • Quantity of apples: You should only eat 1-2 apples per day. Consuming too many apples could make it difficult for you to control your calorie intake.
  • For people with diabetes: Apples have a relatively high sugar content, so those with diabetes need to be cautious when eating apples.
  • For people with stomach ailments: Apples have a high vitamin C content, so those with stomach ailments need to consider this when eating apples.
  • Choosing apples: You should choose apples that are from a clear, reputable source, as apples are often sprayed with plant protection products and can be stored for quite a long time.
  • Not eating apple seeds: Apple seeds can be harmful to your health in some cases, so you should avoid eating them.
