Carbs in apples
Apples are mainly composed of carbs and water. They’re rich in simple sugars, such as fructose, sucrose, and glucose.
Despite their high carb and sugar contents, their glycemic index (GI) is low, ranging 29–44 (5).
Due to their high fiber and polyphenol counts, fruits often have a low GI score (
Apples are very rich in fiber. A single medium-sized apple (100 grams) contains about 4 grams of this nutrient, which is 17% of the Daily Value (DV).
A portion of their fiber comes from insoluble and soluble fibers called pectin. Soluble fiber is associated with numerous health benefits, partly because it feeds the friendly bacteria in your gut (8, 9,
SUMMARY Apples are mainly made up of carbs and water. They also contain fiber, which moderates blood sugar levels and promotes gut health.
Apples boast many vitamins and minerals, though not in high amounts. However, apples are usually a good source of vitamin C.
- Vitamin C. Also called ascorbic acid, this vitamin is a common antioxidant in fruits. It’s an essential dietary nutrient that has many important functions in your body (
- Potassium. The main mineral in apples, potassium may benefit heart health when consumed in high amounts.
SUMMARY Apples are not particularly rich in vitamins and minerals. However, they contain decent amounts of both vitamin C and potassium.
- Quercetin. A nutrient that also occurs in many plant foods, quercetin may have anti-inflammatory, antiviral, anticancer, and antidepressant effects, according to animal studies (
14, 15, 16, 17).
- Catechin. A natural antioxidant, catechin is also present in large amounts in green tea and has been shown to improve brain and muscle function in animal studies (
- Chlorogenic acid. Also found in coffee, chlorogenic acid has been found to lower blood sugar and cause weight loss in some studies (
SUMMARY Apples are a good source of several antioxidants, including quercetin, catechin, and chlorogenic acid. These plant compounds are responsible for many of apples’ benefits.
Two properties of apples — their high fiber and low calorie contents — make them a weight-loss-friendly food.
In one 12-week study, women who were instructed to eat 1.5 large apples (300 grams) per day lost 2.9 pounds (1.3 kg) over the course of the study (23).
For this reason, this fruit may be a useful addition to a weight loss diet, especially if eaten between or before meals.
SUMMARY Apples may compliment a healthy weight loss diet largely due to their high fiber and low calorie counts.
Given the immense popularity of apples, it unsurprising that they’ve been studied quite thoroughly (
Blood sugar control and type 2 diabetes
Some of the antioxidants in apples may also slow down your digestion and absorption of sugars (24).
Blood cholesterol and heart disease
Several studies have examined apples’ effects on risk factors for heart disease.
A human study in Finland showed that those who consumed more than 1.9 ounces (54 grams) of apples per day were at a significantly lower risk of developing heart disease.
Specifically, the risk of dying from heart disease was 43% lower in women and 19% in men (
Potential evidence exists from studies in people as well.
SUMMARY Some studies indicate that apples may help protect against diabetes, heart disease, and cancer.
Apples are generally well tolerated.
However, they may cause problems for people with irritable bowel syndrome (IBS) because they contain FODMAPs, a wide category of fibers that cause digestive symptoms, including gas and abdominal pain, in some people (
Their fructose content may also be problematic for people with fructose intolerance.
SUMMARY Apples are generally considered healthy but may cause digestive problems in some people.
Apples are healthy, tasty, and among the most popular fruits in the world.
Although they are not particularly rich in vitamins and minerals, they’re a good source of fibers and antioxidants.
Apples may have several benefits, including improved heart health and a lower risk of cancer and diabetes. They may also aid weight loss.
If you want to eat healthy, apples are an excellent choice.
