Calories: 87Water: 77%Protein: 1.9 gramsCarbs: 20.1 gramsSugar: 0.9 gramsFiber: 1.8 gramsFat: 0.1 grams


Potatoes are greatly composed of carbs, mostly in the form of starch. The carb content varieties from 66–90% that dry weight (2, 3, 4).

Simple sugars — such as sucrose, glucose, and fructose — are additionally present in little amounts (5).

Potatoes normally rank high on the glycemic table of contents (GI), making them unsuitable for people with diabetes. The GI measures how foods influence your increase in blood street after a meal.

However, some potatoes may be in the medium selection — depending on the variety and cooking methods (6, 7).

Cooling potatoes after food preparation may lessen their effect on blood sugar and also lower your GI by 25–26% (8, 9).


Even despite potatoes room not a high-fiber food, they may administer a far-reaching source that fiber because that those that eat lock regularly.

The level the fiber is highest in the skin, which renders up 1–2% the the potato. In fact, dried skin are around 50% fiber (10).

Potato fibers — such as pectin, cellulose, and hemicellulose — are greatly insoluble (11).

They additionally contain varying quantities of resistant starch, a form of fiber that feeds the familiar bacteria in your gut and improves digestive health (12).

Resistant strength can additionally improve blood sugar control, moderating your climb in blood street after meals (13).

Compared to warm potatoes, cooled ones offer greater amounts that resistant strength (8).


Potatoes are low in protein, ranging from 1–1.5% once fresh and 8–9% by dry weight (10, 14).

In fact, compared to other typical food plants — such together wheat, rice, and also corn — potatoes have actually the shortest amount of protein.

Carbs room the main dietary ingredient of potatoes. Those cooled down after boiling may carry out some resistant starch, which have the right to improve gut health. Potatoes also contain little amounts the high-quality protein.

Potatoes space a an excellent source of numerous vitamins and minerals, an especially potassium and also vitamin C.

The level of some vitamins and minerals drop during cooking, but this reduction have the right to be reduced by baking or boiling them v the skin on.

Several observational studies and randomized regulated trials link high potassium intake to a lessened risk the high blood pressure and heart an illness (17, 23, 24).

Other building material in potato that might promote lower blood pressure encompass chlorogenic acid and kukoamines (25, 26).

Fullness and Weight Management

Foods that are an extremely filling may add to load control, expanding the feeling of fullness after ~ meals and reducing food and calorie input (27).

Another little trial in 11 guys showed the eating boiled potatoes as a side with pork steak led to less calorie intake throughout the enjoy the meal when contrasted to pasta or white rice (29).

Thus, potato may assist weight ns by help you reduce all at once intake.

Studies show that proteinase inhibitor 2 (PI2), a potato protein, might suppress appetite (30, 31).

Even despite PI2 might suppress appetite when taken in that pure form, it is unclear whether it has any effect in the trace amounts present in potatoes.


Potatoes are fairly filling. Because that this reason, they might be useful as a part of a weight loss diet.

Potato Toxins

Plants the the nightshade family, such as potatoes, contain a class of toxic phytonutrients recognized as glycoalkaloids.

The two main glycoalkaloids in potatoes room solanine and chaconine.

Glycoalkaloid poisoning after eat potatoes has actually been report in both people and animals (35, 36).

However, reports of toxicity are rare and the problem may go undiagnosed in many cases.

In low doses, glycoalkaloids usually cause mild symptoms, such together headache, stomach pain, diarrhea, nausea, and vomiting (35).

In more serious cases, the symptoms encompass neurological disorders, rapid breathing, quick heartbeat, short blood pressure, fever, and even death (36, 37).

In mice, long-term intake the glycoalkaloids may boost the hazard of cancer in the brain, lungs, breasts, and also thyroid (38).

Other pet studies show that the short levels the glycoalkaloids likely found in the human being diet may exacerbate inflammation bowel disease (IBD) (39).

Normally, potatoes contain only trace amounts of glycoalkaloids. A 154-pound (70-kg) separation, personal, instance would have to eat over 13 cup (2 kg) of potato (with the skin) in someday to gain a lethal dose (37).

That said, lower amounts may still reason adverse symptoms.

The levels of glycoalkaloids are greater in the peel and also sprouts than various other parts the the potato. It’s best to protect against eating potato sprouts (37, 40).

Potatoes affluent in glycoalkaloids have a bitter taste and cause a burning sensation in her mouth, an effect that may be a warning sign of potential toxicity (41, 42).

Compared to other foods, french fries and also potato chips are really high in acrylamides (48).

These compound are offered as commercial chemicals, and acrylamide toxicity has actually been report in people exposed come them in the rectal (49, 50, 51).

Although the lot of acrylamides in foods items is typically low, irreversible exposure may be harmful.

Animal studies show that acrylamides may rise cancer risk and also harm the brain and nervous device (52, 53, 54, 55, 56, 57).

In humans, acrylamides have actually been classified together a possible risk element for cancer (45).

Numerous observational studies have investigated the result of eat acrylamide-rich foodstuffs on cancer risk, and also most did not detect any significant adverse impacts (58, 59, 60, 61).

In contrast, a few studies have linked acrylamides with an boosted risk of cancer the the breasts, ovaries, kidneys, mouth, and also esophagus (62, 63, 64, 65, 66, 67).

High entry of acrylamides may have adverse health impacts over time, however the level of these results is unclear, and also further studies are required.

For optimal health, the seems sensible to limit your intake of french fries and potato chips.

Fried potatoes and potato chips may likewise contain acrylamides, glycoalkaloids, and also high quantities of salt, which all might be harmful over time (45, 70, 71).
