Good, cheap, versatile, but also rich in properties and nutrients! Potatoes are an excellent food, suitable for everyone and too often demonized for theirs energy and carbohydrate power. 


Instead, they can be an excellent alternative to pasta or bread, if cooked healthily and combined with the right foods. For example, associating potatoes with a source of protein, a source of fat and fiber, significantly lowers their glycemic index.


Furthermore, they can be kept for a long time, even for several months if placed in the dark and at a temperature between 4 ° and 10 ° but without placing them in the refrigerator.


Properties and benefits some potatoes

Often we think of potatoes only as a source of carbohydrates and sugars, but, instead, inside these precious tubers they hide numerous nutrients and properties. Let's see some of them:

  • Potatoes are rich in antioxidants, such as flavonoids, carotenoids and phenolic acids that counteract the appearance and functionality of free radicals, associated with aging and chronic diseases.
  • They contain resistant starch, not fully absorbed from the intestine and associated with improved insulin sensitivity.
  • They improve digestion and inflammation, thanks to resistant starch, which is converted into short-chain fatty acids, useful for intestinal health and to reduce the risk of inflammation-associated diseases.
  • They have a high satiating power, useful for regulating appetite and maintaining body weight.
  • Potatoes are naturally gluten-free, therefore, suitable in case of celiac disease or gluten sensitivity.

Curiosities about potatoes

Potatoes appeared about 8.000 years ago in a region between Bolivia and Peru, but for many centuries they were thought to be poisonous and associated with leprosy.


Le chips were invented back in 1853 by an Indo-American chef, George Crum, intent on annoying a too demanding customer of the luxury restaurant where he worked, who had sent back a plate of "french fries" three times, because they weren't thin enough. Exasperated, the chef decided to take revenge and cut the potatoes into very thin slices, so that, once fried, they would be so hard that they could not be eaten. It was not so: the customer was enthusiastic about the recipe and the dish became a specialty of the restaurant. So a few years later, Crum opened a restaurant that offered a basket of fries at each table.


A raw slice applied over a sunburn for 15-20 minutes, soothes the pain. With the same system, it is possible remove the discomfort and redness of mosquito bites.
