Sweet potatoes: is it good for those who do weight training? See benefits

The potato sweet food is usually a well – known among people who perform hypertrophy training (gain muscle mass).

This is due to its low glycemic index, which provides energy gradually for the body to perform exercises, helping to improve performance during activities.

However, sweet potatoes are not just for those looking for lean mass gain . It is also rich in nutrients, which help to keep the body healthy.

Thus, it is ideal for those looking to include healthier dishes in the daily diet.

What kind of carbohydrate is sweet potato?

Carbohydrates are nutrients present in food, responsible for providing energy for the body to perform daily tasks.

Its main functions are the production and storage of energy, as well as helping to structure the body’s cells.

There are two types of carbohydrates: simple and complex. Sweet potatoes are part of the complexes.


Simple carbohydrates are those quickly digested by the body, as they have a high glycemic index (the speed with which the carbohydrate reaches the bloodstream).

When ingesting a simple carbohydrate, it is absorbed by the body quickly, which generates a spike in blood glucose, that is, a rapid increase in blood sugar levels.

This consequently causes a greater release of insulin – the hormone responsible for collecting blood sugar and sending it to the cells of the body.

This increase in insulin causes the body to identify that there is an excess of glucose in the body, available to be used as energy.

It turns out that, in general, the body cannot use all the high amount of energy at once.

In this way, insulin stores excess sugars in the form of fat in adipose tissue.

In addition, the rapid digestion of carbohydrates causes the sensation of hunger in a short period after the meal, making it necessary to consume food again.

Therefore, in some weight loss diets, the intake of complex carbohydrates is indicated, which, in general, delay the reappearance of hunger.


Complex carbohydrates – also known as “good carbohydrates” – are those that are slowly digested by the body and have a low glycemic index.

When ingesting a complex carbohydrate, the body digests it at a slow speed, gradually releasing glucose into the bloodstream.

This occurs, in general, due to the presence of fibers in complex carbohydrates, which cause the digestion speed to decrease.

Thus, there is no peak of blood glucose, that is, a rapid rise in blood sugar levels.

Thus, there is only the release of a moderate amount of glucose into the blood that, in general, the body is able to use in daily physical activities.

This means that the body does not necessarily need to store energy in the form of fat in the body.

In addition, the slow digestion caused by the consumption of complex carbohydrates causes the food to remain in the stomach for a longer time, causing a feeling of satiety for a longer time.

Nutrients: what is sweet potato for?

Because of the different nutrients present in its composition, sweet potatoes, in general, assist in the functioning of various areas of the body, such as the intestine, eyes and even the heart.

Specifically, it serves to:

Immune system

Sweet potatoes can be a good ally in strengthening the immune system.

That’s because it’s rich in vitamin C and beta-carotene, a pigment that turns into vitamin A when it enters the bloodstream.

Vitamin C helps in the production of white blood cells – defense cells – and provides antioxidant action, that is, it protects the body against the action of free radicals, molecules capable of damaging healthy cells in the body.

Vitamin A, on the other hand, strengthens the body against degenerative diseases and also provides antioxidant action.


The fibers present in sweet potatoes make the food good for the functioning of the intestine.

They facilitate the digestion process and improve intestinal transit, preventing problems such as constipation , for example.


Because of the presence of potassium and vitamin B6 in its composition, sweet potatoes are good for heart health.

Potassium helps to control blood pressure, preventing heart attacks. Vitamin B6 acts as a heart protector, helping to prevent heart disease.

In addition, the food also contains fibers that act in the control of cholesterol, helping to reduce the risk of cardiovascular complications.


One of the organs benefited from the consumption of sweet potatoes is the skin. The root is a source of vitamins A, E and C, which have antioxidant action, that is, they prevent against premature aging.

These vitamins also act by stimulating the production of collagen, the protein responsible for the youthful aspect of the skin.

In addition, vitamin A promotes cell renewal, that is, it causes old cells in the epidermis to be replaced by new cells, improving the appearance of the dermis.


The consumption of sweet potatoes can help maintain healthy eyesight, since food is a source of vitamin A.

This vitamin acts to protect the cornea, part of the eye that transmits and concentrates the external light.

In this way, it helps to prevent against the development of macular diseases, stimulating a healthy vision.

Weight loss

Because it is rich in fiber, sweet potatoes, in general, can help with weight loss.

This is because the fibers act in the digestion process, causing the food to remain in the stomach for a longer time.

In this way, food causes a feeling of satiety, which usually causes the person to eat less, enabling weight reduction.

What is the difference between purple and white sweet potatoes?

There are different types of sweet potatoes such as purple, white and orange, with purple and white being best known in general. They have, not very significantly, some differences between them.

The main ones are:


The amount of calories between the purple and white sweet potatoes does not vary significantly. Between the two, the purple potato is the most caloric.

Purple Sweet Potato (100g)95kcal
White Sweet Potato (100g)92kcal

Thus, for people looking for a daily diet based on low calorie levels, white sweet potato is the best option.


The nutritional characteristics in both foods are similar. However, the purple potato is still more nutritious.

This, because in addition to having the same vitamins and minerals present in white, the purple potato has a greater amount of these nutrients in its skin.

In addition, because of its dark coloring, the food is rich in anthocyanin, a natural pigment that provides antioxidant effects.


The difference between the potatoes can also be seen in the flavor.

In general, the purple sweet potato has a sweeter taste than the white one, in addition to having a softer flesh.

Is sweet potato good for weight training?

-Yeah . Sweet potatoes, as well as other complex carbohydrates, are a good food for those who practice weight training and other activities of high physical effort, as they can help improve performance and muscle hypertrophy.

That’s because of its low glycemic index. When eaten in the pre-workout, the food helps to provide energy gradually and steadily to the body, in order to last, in general, the whole workout.

When receiving this energy, the body does not need to use proteins as an energy source during training, for example.

Without being used for activities, proteins are directed by the body to compose an increase in lean mass , that is, hypertrophy.

Sweet potatoes are fattening?

It depends . Although considered to be fitness, like other foods, sweet potatoes can cause weight gain when eaten in excess. So moderation is always worth it.

If the goal is to replace carbohydrates like rice, the ideal is that the amount of sweet potatoes is the same as the amount normally eaten of grains.

The method of preparation can also interfere with the change in weight. When making cooked food, in general, there is less chance of weight gain than fried or roasted.

This is because one of the reasons that sweet potatoes have a low glycemic index is due to the high content of starch present in its root, which prolongs the digestion period in the body.

When placing in the oven or frying the potato, the heat dehydrates the food and causes the breakdown of the starch molecules, which makes digestion faster, thus increasing the glycemic index.

Are there any harmful effects of consuming?

There is no scientific proof of the health hazards of sweet potatoes.

However, like other foods, their excessive consumption can cause problems in some people, such as allergies, for example.

In addition, eating raw food can also cause discomfort, since when raw, sweet potatoes contain some toxic substances to the body, such as chaconine and solanine (chemical compounds).

Therefore, the ideal is to always cook the food before eating. If consumed in a moderate and healthy way, in general, sweet potatoes have no health hazards.

How to eat healthily?

There are several ways to consume sweet potatoes in a healthy way. Some of them can be differentiated according to the objective: weight loss or muscle mass gain.

To lose weight

For weight reduction, the ideal is to consume sweet potatoes in a moderate way, including food in the main daily meals, as a substitute for more caloric carbohydrates.
