Nutritional benefits of zucchini and prepared potatoes

Zucchini and potatoes offer distinct nutritional advantages depending on preparation and variety. Zucchini is a low-calorie vegetable consisting of approximately 94 percent water, providing roughly 17 to 20 calories per 100 grams. It is a source of fiber, potassium, vitamin C, provitamin A, calcium, magnesium, iron, and B vitamins. According to USDA data, a medium zucchini of 196 grams contains about 39 milligrams of vitamin C.

Potatoes can be made healthier through a specific preparation method. When cooked potatoes are cooled overnight, a portion of their digestible starch converts into resistant starch. This type of starch is not directly digested by the body, resulting in approximately ten percent fewer calories. Resistant starch acts as a fiber, supporting healthy gut bacteria and promoting the production of fatty acids like butyrate, which can have anti-inflammatory effects and aid digestion. To ensure safety, cooled potatoes should be stored in the refrigerator to prevent bacterial growth.
