A medium 5.3 oz potato with skin-on provides 26 grams of carbohydrates, or 9% of the daily value per serving.

A medium 5.3 oz skin on potato has 0.2 mg of vitamin B6 per serving, which is 10% of the daily value and considered to be a good source. Vitamin B6 plays important roles in carbohydrate and protein metabolism.

A medium 5.3 oz skin on potato has 620 mg of potassium per serving, which is 15% of the daily value and more than a medium-sized banana (422 mg per serving). Potassium is an electrolyte essential for muscle functioning. Potassium is lost in sweat, so it needs to be replenished for optimal performance.

A medium 5.3 oz skin on potato has 27 mg of vitamin C per serving, which is 30% of the daily value. Potatoes are considered to be an excellent source of this antioxidant. Vitamin C aids in collagen production—a major component of muscle tissue— and supports iron absorption.

NUTRITION FACTS

If you’re looking to power up your performance, look no further than the potato. Did you know that potatoes provide the carbohydrate, potassium and energy you need to perform at your best? Potatoes are more energy-packed than any other popular vegetable and have even more potassium than a banana. Plus, there’s a potato performance recipe options to fuel your body and brain throughout the day- whether you lead an active lifestyle or are competing with elite athletes.





VITAMIN C

A medium 5.3 oz skin on potato contains 27 mg of Vitamin C, which is 30% of the daily value. Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for humans. Vitamin C is found naturally only in fruits and vegetables.1 Potatoes are an excellent source of vitamin C and contribute significantly to the daily vitamin C requirements for Americans.2,3

KEY FACTS ABOUT VITAMIN C

Vitamin C plays an important role in collagen formation and immune function.

As a potent antioxidant vitamin C stabilizes or eliminates free radicals in the body, thus helping to prevent cellular damage.

Fruits and vegetables are the best and only natural source of vitamin C.

A medium 5.3 oz potato with skin-on is an excellent source of vitamin C, providing 30% of the recommended daily value (DV). This is more vitamin C than one medium tomato (27% DV) or a sweet potato (20% DV).

For men ages 19 years and older, the recommended dietary allowance (RDA) for vitamin C is 90 mg per day. For women ages 19 years and older, the RDA is 75 mg per day.

FUNCTIONS OF VITAMIN C

Vitamin C is required for the synthesis of collagen, a structural protein that gives strength and elasticity to a variety of body tissues (e.g., skin, gums, tendons, ligaments and bone) and plays a vital role in wound healing. Vitamin C also functions as an antioxidant in the body, stabilizing or eliminating free radicals, thus helping to prevent cellular damage. Finally, vitamin C assists with the absorption of iron and is concentrated in a number of immune cells thereby helping to support the body’s immune system.1

VITAMIN C RECOMMENDATIONS

The current RDAs for vitamin C are based on its known physiological and antioxidant functions in white blood cells and, thus, have been set higher than the amounts needed to prevent the deficiency disease (scurvy).1 For men ages 19 years and older, the RDA is 90 mg per day and for women ages 19 years and older the RDA is 75 mg per day.

POTASSIUM

A medium 5.3 oz skin on potato contains 620 mg of Potassium, which is 15% of the daily value. Potassium is a major mineral that plays a number of important roles in the body. Most notably, it is a key electrolyte that helps maintain the delicate balance of fluid inside and outside the cell.1 It is estimated that less than 3% of Americans are meeting the current adequate intake (AI) for potassium as specified by the USDA’s Dietary Guidelines for Americans.2

KEY FACTS ABOUT POTASSIUM

Potassium is an important electrolyte that aids in muscle, cardiovascular and nervous system function. 1

Potassium helps maintain normal blood pressure. Research suggests diets high in potassium and low in sodium may reduce the risk of hypertension and stroke. 2

Potatoes with skin-on are a good source of potassium. This is more potassium in a medium 5.3oz skin on potato than in a medium-size banana. 3

Potatoes provide one of the most affordable sources of potassium, significantly more than those foods commonly associated with being high in potassium, including bananas, oranges and mushrooms.2

FUNCTIONS OF POTASSIUM AND RELEVANT RESEARCH

Research suggests diets rich in potassium and low in sodium reduce the risk of hypertension and stroke.5 In a scientific statement promoting dietary approaches to prevent and treat hypertension, the American Heart Association (AHA) reported that evidence from animal experiments, observational studies and more than 30 human clinical trials show a significant association between high potassium intakes and reduced blood pressure.6

Given their high potassium content, potatoes may contribute to a heart healthy diet. In fact, the Dietary Guidelines for Americans encourages people to increase potassium by focusing on food choices with the most potassium such as white potatoes, beet greens, white beans, plain yogurt, and sweet potatoes.5

POTASSIUM RECOMMENDATIONS

Current recommendations for potassium intake are expressed as an “adequate intake,” or AI. For males 19-50 years of age, the AI for potassium is 3400 mg per day whereas for females 19-50 years of age it is 2600 mg per day.7

CARBOHYDRATES

A medium 5.3 oz skin-on potato contains 26 grams of carbohydrates. Carbohydrate-rich foods like potatoes have been getting a bad rap lately. Many of today’s most popular fad diets recommend restricting all or specific carbohydrate-rich foods. This is unfortunate because carbohydrates have many important functions and eliminating them from the diet is neither necessary nor healthy.

KEY FACTS ABOUT CARBOHYDRATES

One medium 5.3 oz potato with skin-on provides 26 grams of carbohydrates, or 9% of the daily value per serving.

The brain + red blood cells require carbohydrates.

Consume 130 grams of carbohydrates per day for central nervous system support.

Choose carbohydrates high in “nutrient density”

Fruits + vegetables are excellent carbohydrates

FUNCTIONS OF CARBOHYDRATES

The primary function of carbohydrates is to provide energy to the cells of the body, particularly the brain. While most body tissues and organs prefer carbohydrate as their primary fuel source, some, like the brain, red and white blood cells, and certain parts of the kidney require it. 1 Carbohydrates are also an important fuel for the muscles during exercise, particularly intense and/or prolonged exercise, and as such are key to optimal athletic performance. 2

In fact, carbohydrates are so crucial to the body that if you don’t consume adequate amounts in your diet, your body will have to make them—a process known as “gluconeogenesis” (literally translated “to make new glucose”). The most common gluconeogenic substrates are amino acids derived from both dietary sources of protein and body proteins such as muscle and vital organs. 2 Thus, while the body can survive without carbohydrates; it does so at the expense of the body’s protein pool and consequently does not function optimally. 2

CARBOHYDRATE CLASSIFICATION

Carbohydrates can be broadly classified as simple or complex, based on their chemical structure.

Simple carbohydrates, as their name implies, have a simple chemical structure consisting of one or two sugar molecules. Examples include the monosaccharides (single sugars)—glucose, fructose, galactose—and the disaccharides (two sugars)—sucrose, lactose, and maltose. Most fruits and dairy products contain an abundance of simple sugars. Soft drinks, ice cream, sweets and pastries also contain significant amounts of simple sugars. 3

Complex carbohydrates, including starch, glycogen, fiber and resistant starch, have a more complex chemical structure, containing two or more sugar molecules linked together. 3 Glycogen is the body’s storage form of glucose, while starch is a plant’s storage form of glucose. Foods rich in starch include grains, cereals and most vegetables, particularly beans, peas, corn and potatoes. 3

CARBOHYDRATE RECOMMENDATIONS

The current RDA for carbohydrates is 130 grams per day based on the amount needed to optimally support the central nervous system (i.e., the brain). 1 If you engage in physical activity, you need more carbohydrate. How much more depends on the intensity and duration of your exercise. 4 The Food and Nutrition Board of the Institute of Medicine (the government body that sets the RDA) has recommended an acceptable macronutrient distribution range (AMDR) for carbohydrates of 45-65% of total daily energy intake. 1

Some people hold the misconception that they need to cut out carbohydrates to manage body weight. But scientific consensus asserts that excess calories are to blame for weight gain, not diet composition. 5 Instead of restricting carbohydrates from your diet, practice common sense when selecting carbohydrate-rich foods—choose nutrient dense whole grains, fruits and vegetables.

PROTEIN

A medium 5.3 oz skin on potato has 3 grams of protein. Protein is an important component of almost every cell and tissue in the body. Protein is made up of amino acids. There are 20 amino acids with biological significance; however, only nine are essential, meaning that our bodies cannot synthesize them and they must be obtained through food.

KEY FACTS ABOUT PROTEIN

A medium-size 5.3 oz potato with skin-on provides 3 grams of plant-based protein.

The 3 grams of protein in one skin-on 5.3 oz potato exceeds that of all other commonly consumed vegetables, except dried beans. 1

The Dietary Guidelines for Americans recommend eating a variety of plant-based foods to improve overall health.3

FUNCTIONS OF PROTEIN

Proteins play many important roles in the body including:

Providing structure: Protein is a key component of muscle, tendons, ligaments and connective tissues like collagen. In addition, our skin, hair and nails contain significant amounts of protein.

Regulating metabolic processes: Enzymes which catalyze chemical reactions, hormones which regulate metabolic processes and cytokines that bind to the surface of cells and influence their functions are all proteins.

Transporting substances: Transport proteins carry important substances in the body. For example, hemoglobin and myoglobin carry oxygen, albumin carries several vitamins and minerals as well as fatty acids, and transferrin and ferritin carry iron.

Balancing fluid and electrolytes: Proteins, especially those found in the blood, help regulate fluid balance. Amino acids can be either positively or negatively charged, thus allowing them to help the body achieve acid-base balance and optimal pH.

Providing energy: Protein provides 4 calories per gram (similar to carbohydrate); however, under normal circumstances protein contributes little to energy production. Under stressful conditions (e.g., severe illness, starvation, diabetic ketoacidosis) protein becomes a more significant source of energy; but, to the detriment of health.

PROTEIN RECOMMENDATIONS

The current recommended dietary allowance (RDA) for protein is .8 grams per kilogram of body weight and the acceptable macronutrient distribution range (AMDR) is 10%-35% of total daily energy intake from protein. One 5.3-ounce skin-on potato is a source of 3 grams of plant-based protein. Current dietary guidance, including the Dietary Guidelines for Americans, recommends substituting plant-based proteins for some animal-based proteins to improve overall health and support the environment.

FIBER

A medium 5.3 oz skin on potato has 2g of dietary fiber. Dietary fiber is a type of complex carbohydrate found in vegetables, fruits and whole grains. Most Americans get only about half of the recommended amount of dietary fiber and, thus, could benefit from consuming more fiber-rich foods.

KEY FACTS ABOUT FIBER

A medium 5.3 oz potato with skin-on provides 2 grams of fiber, or 7% of the daily value per serving.

Dietary fiber has been shown to have numerous health benefits, including improving blood lipid levels, regulating blood glucose, and increasing satiety, which may help with weight loss. 1

A common misconception is that all of the fiber in a potato is found in the skin. While the skin does contain approximately half of the total dietary fiber, the majority (> 50 percent) is within the potato itself. 3

In the United States, recommendations for fiber intake are often made relative to calorie intake. The current recommend intake for fiber is 14g/1,000 kcal; thus, an average adult woman should consume 25 grams of fiber per day and the average male should consume 38 grams of fiber per day.2

FUNCTIONS OF FIBER

Dietary fiber has been shown to have numerous health benefits, including improving blood lipid levels, regulating blood glucose, and increasing satiety, (makes you feel full longer), which may help with weight loss.1

FIBER RECOMMENDATIONS

The current recommended dietary allowance (RDA) for fiber is 25 g per day for women 19-50 years of age (28 g per day if pregnant or lactating) and 38 g per day for men 19-50 years of age.5
