Are Apples Keto?

There are many types of apples, and they all have different tastes. You can find fruits from sweet reds and fragrant yellows to sour green apples that will surprise you with their bright taste. How many carbohydrates do apples contain? Are they good for the keto lifestyle? Can you eat them while on a keto diet?

Depending on the type, 100 grams of apples contains:

  • 41-59 calories
  • 3 grams of protein
  • 2 grams of fat
  • 12-16 grams of carbohydrates
  • 2-3 grams of fiber
  • 10-14 grams of net carbs.

As you can see, apples are too high in carbs and, as a result, cause spikes in blood glucose levels, interrupting ketosis and promoting fat cells growth. One medium apple contains approximately 20 grams of net carbs. As you know, it is already your entire daily carb count. In addition, all the carbs in apples are made up of fructose, which is quickly and easily converted into sugar through metabolism. At the same time, sour green apples contain fewer carbs, while sweet red apples have the highest amount of fructose. However, you should avoid all types of apples if you are on a strict keto diet and want to stay in ketosis to lose weight. So, unfortunately, no apple pie and no apple crumble on keto. But you still have many low-carb alternatives.

You can also eat a little if you maintain weight after losing it on keto or follow a cyclical keto diet for muscle building. In any case, monitor how you feel and how your body reacts to it. If apples do not interrupt your ketosis, use a couple of slices in a salad or a healthy smoothie for all the benefits.

Apples Health Benefits

The useful properties of apples are determined by their unique composition. Despite the variety of types, tastes, colors, and shapes of apples, the beneficial elements contained in these fruits are almost the same. About 80% of the total composition of apples is water. The remaining 20% ​​is fiber, carbohydrates, and various organic acids. By the way, you can get some benefit even from the seeds of this fruit if used wisely.

The concentration of important components is highest in fresh apples. When eating apples, your body receives the following substances:

  • Pectin and fiber improve intestinal health and promote the cleansing of toxins. Fiber helps restore a healthy gut microbiome and eliminate digestive problems.
  • Antioxidants that slow down the oxidative processes in your body and protect against various diseases associated with oxidative stress.
  • Tannins have an anti-inflammatory effect in diseases of the cardiovascular and genitourinary systems. In addition, they help your body fight chronic inflammation and reduce the effects of autoimmune diseases.
  • Tannins prevent salts’ precipitation, which in turn is an excellent prevention of diseases of the kidneys and genitourinary system.
  • Vitamins C, B1, B2, E, and P, perform various functions, from maintaining the health of the eyes and bones to the health of the circulatory system and skin.
  • The health benefits of apples are explained by the content of minerals such as copper, potassium, magnesium, zinc, calcium, and chlorine. In addition, apples contain a large amount of iron. It is good for blood quality. Besides, apples have calcium, which is necessary for the cardiovascular and skeletal systems.

Let’s look at the main benefits of apples for your health.

Decreased Cholesterol Level in the Blood

A 2013 scientific study of nearly 75,000 Swedish men and women over 10 years found that the group with the highest apple consumption had a lower risk of stroke [3]. Due to the high content of pectin and vegetable fibers, apples lower blood cholesterol levels. One apple with the peel contains 3-4 g of fiber, which is more than 10% of a person’s daily requirement. A peeled apple contains 2-3 g of fiber. Insoluble fiber molecules help remove cholesterol from the body. Thus, they reduce the risk of blockage of blood vessels [4] by cholesterol plaques. In addition, apples contain polyphenols that have antioxidant effects. For example, they have epicatechin, which lowers blood pressure.

Healthy Digestion and Gut Microbiome

Dietary fiber, which we have discussed above, helps maintain blood cholesterol levels and prevents digestive problems (constipation, bloating, etc.). Moreover, pectin absorbs toxins in the intestines, stimulates its peristalsis, and prevents bloating and the formation of gallstones [5].

In addition, apples are considered a good natural remedy for indigestion. And due to the high content of vitamin B2, they are good to use to increase appetite.

Rich Vitamin Composition

Apples are used with a lack of nutrients, as they contain many vitamins and minerals. Apple juice contains a lot of hematopoietic elements – iron and manganese. In addition, it contains potassium, sodium, and calcium in good proportions. In other words, it strengthens the cardiovascular system well [6]. Apples have a tonic effect and increase the body’s resistance to free radicals. These fruits strengthen the immune system and help you resist various infections.

Apples are very useful for people who lead a healthy lifestyle, as well as for mental workers and those who lead a sedentary lifestyle. The high content of fructose and organic acids helps to normalize metabolism and restore the body after physical exertion. As a result, apples restore metabolism, normalize salt balance, help rejuvenate the body and slow down the aging process [7].

Pectins bind and remove salts of heavy metals (arsenic, lead) from the body. Apples prevent the formation of uric acid. Therefore, they are useful for gout and chronic rheumatism. Due to their diuretic effect, apples also help to eliminate harmful substances from the body. They contain chlorogenic acid, which, together with pectin, helps to eliminate oxalate salts from the body.

Strong Mental Health

Phosphorus macronutrients contained in apples stimulate brain activity and strengthen the nervous system. Therefore, if you suffer from insomnia, try eating an apple or drinking a glass of apple juice before bed. Also, this fruit has a calming effect and helps fight stress.

Reducing the Risk of Cancer and Diabetes

The peel of an apple contains a high amount of the antioxidant quercetin, which, together with vitamin C, prevents free radicals from having a harmful effect on the body. Pectin and insoluble fiber also have anti-cancer effects [8]. They prevent constipation and remove harmful substances from the body. Thus, they reduce the likelihood of developing colon cancer. As you know, it is a problem of modern civilization caused by the excessive consumption of processed foods.

The antioxidant effect of flavonoids in apples may protect cells from pancreatic damage. This organ is responsible for the secretion of insulin. Scientists studied almost 38,000 women as part of a large Women’s Health project that lasted for nine years. This study confirmed a positive association between regular apple consumption and a reduced risk of type 2 diabetes [9]. Those who eat at least one apple a day have a 28% lower risk of type 2 diabetes compared to those who eliminate these fruits from their diet.

Healthy Weight Loss

Regular consumption of apples helps healthy weight loss for several reasons. Studies show that people who eat an apple slice before a meal feel fuller [10]. Also, people who start each meal with a piece of an apple eat an average of 200 calories less than those who start their meals as usual.

Another study found that women who replaced oatmeal cookies for apples during a two-month diet lost an average of 2 pounds more [11]. Apples help you lose weight due to their high fiber content and improved metabolism.
