Potatoes

They are a good source of vitamin K, along with carbohydrates acting as high-calorie food for weight gain. The starch in potatoes enables the release of energy in the form of glucose.

Potatoes are the king of guilty pleasures: baked french fries, wedges or simply the good old jacket potato.

Jacket potatoes can be made easily as following:
Heat oven to 350 F. Rub 2 tsp olive oil over 4 large baking potatoes and put on the top shelf of the oven.
Bake for 20 mins, then turn down the oven to 300 F and bake for 45 mins.
Cut a cross on top of each potato, squeeze the sides, add your favourite topping.
