Common potato-based foods include French fries, potato chips, and potato flour. Learn everything you need to know about them and their nutrition in this article. These contain vitamin C and potassium. Depending on how you cook it, it can provide health benefits.https://www.healthline.com/nutrition/foods/potatoes

Nutrition Information of Potatoes

Boiled in their skins are rich in many vitamins and minerals, including potassium and vitamin C. Aside from being high in water, fresh  are mostly carbohydrates and contain moderate amounts of protein and fiber but very little fat.https://www.medicalnewstoday.com/articles/280579

The nutrients per 100 grams of boiled whole potatoes are:

  • Water: 77%
  • Calories: 87
  • Protein: 1.9 grams
  • Carbs: 20.1 grams
  • Sugar: 0.9 grams
  • Fiber: 1.8 grams
  • Fat: 0.1 grams


Carbohydrates, mainly in the form of starch, constitute potatoes. The carbohydrate content on a dried basis is 60–80%. Monosaccharides such as sucrose, glucose, and fructose are also present in small amounts. These typically have a high glycemic index (GI), making them unsuitable for diabetics. GI measures how a meal affects the rise in blood sugar after a meal. Some potatoes land in the middle range, depending on their type and cooking method.  Chilling after cooking reduces their effect on blood sugar levels, lowering their GI by 25–26%.


These are not a high-fiber food, but they are an important source of fiber for those who eat them regularly. The skin has the highest fiber content, accounting for 1–2% of potatoes. Dried skin contains about 52% fiber. The fibers like pectin, cellulose, and hemicellulose are mostly insoluble. They also contain varying amounts of resistant starch, a type of fiber that feeds good bacteria in the gut and improves digestive health. Resistant starch may also improve blood sugar control and moderate postprandial blood sugar spikes. Cold potatoes contain more resistant starch than hot potatoes.


They have a low protein content of 1–2% fresh weight and 8–9% dry weight. These have the lowest protein content when compared to other common food crops such as wheat, rice, and corn. Anyhow, the protein quality is very high for a plant, even higher than that of soybeans and other legumes. Some people are allergic to patatin, the main protein in potatoes

Vitamins and minerals

Potatoes are an excellent source of various vitamins and minerals, especially potassium and vitamin C. Cooking reduces the content of some vitamins and minerals. You can minimize this loss by baking or cooking them with the skin on.

 Potassium. The skin concentrates potassium, the main mineral, and may provide benefits for heart health.

Vitamin C. Cooking significantly reduces the vitamin C content in potatoes, but leaving the skin on appears to minimize this loss.

Folic acid• Flesh-colored potatoes contain and concentrate high amounts of folic acid

Vitamin B6 •Most foods contain Vitamin B6, a B vitamin that plays a role in the formation of red blood cells.

Other plant compounds

These are rich in bioactive plant compounds, mainly concentrated in the skin. Varieties with purple or red skin and flesh have the highest levels of polyphenols, a type of antioxidant. • Chlorogenic acid, which is the main polyphenol found in them. Catechins.  Catechins are antioxidants, accounting for about one-third of the total polyphenol content, and are most abundant in purple sweet potatoes. • Lutein.  Lutein, found in yellow-fleshed potatoes, is a carotenoid antioxidant that may improve eye health.

• Glycoalkaloids.  Glycoalkaloids are a class of toxic phytonutrients produced by these as a natural defense against insects and other threats. Glycoalkaloids can have harmful effects when taken in large amounts.

Health Benefits of Potatoes

In their skin, they have many health benefits.

 Heart health

Hypertension is a harmful condition characterized by abnormally high blood pressure. It is one of the major risk factors for heart disease. They contain many minerals and plant compounds that may help lower blood pressure. Of particular note is the high potassium content of potatoes. Several observational studies and randomized controlled trials have linked high potassium intake with a reduced risk of high blood pressure and heart disease. Other substances in potatoes that may help lower blood pressure include Chlorogenic acid and possibly kukoamine.

Satiety and weight management

Satiety foods can help with weight management, make you feel fuller longer after eating, and reduce food and calorie intake. Compared to other carbohydrate-rich foods, potatoes are particularly filling. An old study of 40 common foods found potatoes to be the most filling. Another older study of 11 men showed that eating boiled potatoes as a side dish resulted in a lower dietary caloric intake compared to pasta and white rice. Therefore, they support weight management by reducing overall intake.

Studies suggest that proteinase inhibitor 2 (PI2), a protein in potatoes, may suppress appetite. Pure forms of PI2 may suppress appetite, but it is unclear whether trace amounts of PI2 in them have any effect. Generally, these are safe and healthy. However, in some cases, it may be necessary to limit consumption or stop it altogether.

 Potato allergy

A food allergy is a common condition characterized by an immune response to proteins found in certain foods. Potato allergies are relatively rare, but some people are allergic to patatin. It is one of the major proteins found in potatoes. People with latex allergies can also become sensitive to patatin due to a phenomenon known as allergic cross-reactivity.

Potato poison

Solanaceous plants, such as potatoes, contain a class of toxic phytonutrients known as Glycoalkaloids. The two main Glycoalkaloids found in these are solanine and chaconine. Glycoalkaloid poisoning after eating them has been reported in both humans and animals. However, reports of toxicity are rare, and in many cases, the disease may go undetected. At low doses, Glycoalkaloids usually cause mild symptoms such as headache, abdominal pain, diarrhea, nausea, and vomiting.

In more severe cases, symptoms include nerve damage, increased respiratory rate, rapid heart rate, low blood pressure, fever, and even death. Some animal studies suggest that small amounts of Glycoalkaloids likely in the human diet may exacerbate inflammatory bowel disease (IBD). These normally contain only trace amounts of Glycoalkaloids. A person weighing 70 kg would need to eat at least 13 cups (2 kg) of potatoes (with skin) a day to be lethal.

However, even small amounts can cause unwanted symptoms. The Glycoalkaloid content is higher in the skin and shoots than in other parts of the potato. It is better not to eat potato sprouts. Potatoes rich in Glycoalkaloids have a bitter taste and cause a burning sensation in the mouth. Which may be a warning sign of potential toxicity. Some potato varieties with Glycoalkaloid levels above 25 mg per cup cannot be sold commercially.


When carbohydrate-rich foods are cooked at very high temperatures, acrylamide is produced. Such as roasting or baking, found in French fries and baked potatoes, but not in raw, boiled, or steamed potatoes. The proportion of acrylamide increases with higher frying temperatures and longer cooking times. French fries and potato chips are rich in acrylamide compared to other foods.

Industrial chemicals are used for these compounds. Persons exposed to these compounds in the workplace have reported acrylamide toxicity  Although the amount of acrylamide in food is generally small, long-term exposure can be harmful. Animal studies suggest that acrylamide may increase the risk of cancer and damage the brain and nervous system. Humans may be exposed to acrylamide, which is believed to act as a potential cancer risk factor.

However, several observational studies have investigated the effects of intake of acrylamide-rich foods on cancer risk in humans. Most of which have not found significant adverse effects. High intakes of acrylamide can have adverse health effects over time. The extent of these effects is unknown and requires further research. To maintain optimal health, it makes sense to limit your intake of French fries and potato chips.

French fries and potato chips

These have been accused of causing obesity, cardiovascular disease, and diabetes. The main reason is that these are commonly consumed as French fries and potato chips. These are high-fat foods that contain many unhealthy compounds. French fries are also often associated with fast food. Observational studies have linked the consumption of baked chips to weight gain.

French fries and potato chips may contain acrylamide and higher amounts of salt, which can become harmful over time. For this reason, large amounts of French fries, especially French fries, and potato chips should be avoided.

Who should avoid potatoes?

People who are allergic to these or the ingredients in them should avoid eating these potatoes. Some people believe that these and other vegetables in the nightshade family may exacerbate autoimmune diseases such as irritable bowel syndrome. However, more research is needed to know for sure. People with autoimmune diseases should avoid these. These can be consumed as part of a nutritious diet.

However, the consumption of French fries, including French fries and potato chips, should be limited. Especially, those trying to control their weight and those at high risk for cardiovascular disease and diabetes.

How to cook potatoes

There are many ways to cook them. Different cooking methods have different flavor and texture characteristics. Cooking methods can have a significant impact on the nutritional content. Here’s an overview of the most common ways to prepare and how these preparation methods affect their nutritional content.


The boiling process loses water-soluble nutrients such as potassium and vitamin C. As a result, the nutritional value is slightly reduced. The longer the cooking time, the more nutrients are lost. Cooking in their skin preserves some of the water-soluble nutrients.


The fries are cooked in hot oil, and they come with fries and crisps. While the short cooking time of fried foods helps preserve some nutrients, frying in oil significantly increases the fat content of potatoes and Trans fats, unsaturated fats associated with many adverse health effects. Limiting your intake of fried foods such as French fries and potato chips is one of the best ways to reduce your trans-fat intake. Frying also increases the production of potentially harmful chemicals such as acrylamide.


Baking is probably the easiest way to prepare these. Simply scrape the skin, poke the skin with a fork to release the steam, and bake them at 450 F for about an hour. Baking retains more nutrients than boiled or fried ones. They are also rich in dietary fiber, especially if you eat the skin. Keep in mind that common toppings like sour cream, cheese, and butter can drastically change the nutritional profile of potatoes by adding extra fat, calories, and sodium.


Frying is similar to baking. Some people use the terms interchangeably. Baked are usually cooked whole. But they are often chopped and mixed with oil and spices. Both are nutritious ways of cooking. You can find an easy and healthy recipe for perfect roasting.


Cooking potatoes in the microwave is one of the most nutritious and quick ways to cook. Microwaving preserves many of the nutrients that are lost in other cooking methods.


Potatoes are a popular high-carb food that contains several healthy vitamins, minerals, and phytonutrients. In addition, it can support weight management and prevent heart disease. French fries and chips, soaked in oil and cooked over high heat, are not affected by this. To maintain optimal health, it’s best to limit or avoid these products altogether.

Storage and shelf life

Did you know that potatoes keep very well? How long can it be stored on the shelf? To see how something has been cooked and how it has been stored are among other things that need to be done when watching.  Uncooked potatoes stay fresh for weeks or months. After cooking, you can refrigerate these for 3-4 days or freeze them for up to 1 year. Signs that food is undercooked include dark spots on the skin, a soft or mushy texture, and a foul odor.

Boiled can get moldy, but they can also rot without any noticeable signs. Raw potatoes are best kept in a cool, dark place with air circulation. Store cooked potatoes below 40 °F (4 °C) in the refrigerator and below -18 °F (0 °F) in the freezer.
