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.

The GI is a measure of how food affects the rise in blood sugar levels after eating. Low values are associated with various health benefits.

Due to their high fiber and polyphenol counts, fruits often have a low GI score.

Fiber

Apples are very rich in fiber. A single medium-sized apple (182 grams) contains 4.37 gramsTrusted Source of this nutrient, which is approximately 16% of the Daily Value (DV)Trusted Source.

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.

Fiber may also help improve fullness and cause weight loss while lowering blood sugar levels and boosting digestive function.

SUMMARYApples 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.

SUMMARYApples are not particularly rich in vitamins and minerals. However, they contain decent amounts of both vitamin C and potassium.

Apples are high in various antioxidant plant compounds, which are responsible for many of their health benefits. These include:

• Quercetin. A nutrient that also occurs in many plant foods, quercetin may have anti-inflammatory, antiviral, anticancer, and antidepressant effects.
• Catechin. A natural antioxidant, catechin is also present in large amounts in green tea and has been shown to improve mitochondrial health.
• Chlorogenic acid. Also found in coffee, chlorogenic acid has been found to lower blood sugar and cause weight loss in some studiesTrusted Source.

SUMMARYApples 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) throughout the study.

For this reason, this fruit might be a beneficial dessert or addition to a meal to add sweetness.

SUMMARYApples may compliment a healthy weight loss diet largely due to their high fiber and low calorie counts.

Given the immense popularity of apples, it is unsurprising that they’ve been studied quite thoroughly.

Blood sugar control and type 2 diabetes

Some evidence suggests that eating apples can help lower blood sugar levels and protect against diabetes.

Some of the antioxidants in apples may also slow down your digestion and absorptionTrusted Source of sugars.

In one study of 38,018 womenTrusted Source, eating 1 or more apples per day was linked to a 28% lower risk of developing type 2 diabetes.

Blood cholesterol and heart disease

Studies have examined apples’ effects on risk factors for heart disease.

A 2020 study Trusted Source of volunteers with high cholesterol found that apples can reduce total cholesterol levels and improve overall blood flow. However, the study saw no discernible effect on blood pressure.

Cancer

Many test-tubeTrusted Source and animal studiesTrusted Source suggest that apple phytonutrients can protect against cancers of the lungs and colon.

Potential evidence exists from studies in people as well.

One 2005 studyTrusted Source indicated that those who consumed 1 or more apples per day were at a lower risk of cancer, including a 20% and 18% lower risk of colorectal and breast cancers, respectively.

SUMMARYSome studies indicate that apples may help protect against diabetes, heart disease, and cancer.
