Nutrition Facts of Potatoes

Nutrition Facts of Potatoes

For 100 g (3 oz) potato:

  • Moderate in calories – 77 calories. This amount is not too high or too low. But, if eaten in excess, it can cause weight gain because the potato is rich in carbs as well, not just calories.
  • Carbs and proteins – 18.4 g of carbs and 2 g of protein. The carbs are needed for quick energy release. On the other hand, proteins are needed for slower energy release throughout the day. Both of them are the main energy sources we need on a daily basis.
  • Fiber – 2.2 g. Fibers are needed for good digestion and regular bowel emptying. Lack of fibers leads to constipation and too much fibers can cause diarrhea or loose stool.
  • Starches – 15.4 g. The starches can show some benefits like lowering blood sugar, or improved insulin sensitivity, as well as better digestion. But, the potato is very rich in starches and this could show a counter effect – raised blood sugar and bad digestion.
  • Sugar – 0.8 g. Potato might not be too rich in sugars. However, if it combined together with the calories and carbs, it could be a fattening food in the long run.
  • Low in fat – 0.1 g. A low amount of fat is good for the blood vessels.
  • Vitamin C – 33%. Potato has quite a good amount of vitamin C. This vitamin is crucial for guinea pigs, to prevent the scurvy disease. But sadly, they cannot receive this through the potato.
  • Thiamin – 5%. Also known as vitamin B1, it keeps the nerves, heart, intestines and stomach healthy. It also helps with the electrolyte flow through muscles and nerves.
  • Niacin – 5%. Also known as vitamin B3, this vitamin can lower cholesterol and reduce arthritis pains.
  • Vitamin B6 – 15%. This vitamin can help prevent anemia. It also reduces stress, helps in producing the happiness hormone, serotonin, and also helps with better sleep.
  • Pantothenic acid – 3%. This is the B5 vitamin. It helps with the creation of blood cells and also converts the foods into energy.
  • Calcium – 12 mg. This mineral creates strong bone tissues. But once the guinea pig is an adult, it doesn’t need much of this mineral.
  • Potassium – 12%. This nutrient is essential for electrolyte and water balance in the body, for lowering blood pressure and keeping the heart healthy too. The deficit of potassium leads to weakness and constipation.
  • Copper – 5%. The copper helps in red blood cells formation. It works together with iron and it helps with anemia prevention, as well as iron absorbing.
