Potatoes are good sources of potassium, which helps lower and stabilize blood pressure. One medium potato with skin provides 18 percent of the recommended daily value of potassium.

Scientists at the Institute for Food Research have discovered that potatoes contain a compound called kukoamine, which are also associated with a reduced risk of high blood pressure.

2. Reduce cardiovascular disease risk

There are approximately 60 different kinds of phytochemicals found in potato. Many of these flavonoids help reduce the risk of cardiovascular disease by lowering the levels of bad LDL-cholesterol and keeping arteries free of fat.

The vitamin B-6 present in potatoes is also useful to protect against heart disease. Vitamin B-6 is capable of reducing the levels of a molecule called Homocysteine. High homocysteine levels are linked with a significantly increased risk of heart attack and stroke.

The high level of carbohydrates in potatoes may help in maintaining good levels of glucose in the blood, which is necessary for proper brain function.

Tips on Selecting the Good Potatoes

When buying potatoes, you should avoid the ones with green spots, sprouting, or any kind of bruising. When exposed to light, potatoes develop green spots, which contain a substance called solanine that is not only tastes bitter, but it is also poisonous. Sprouting indicates the potato is not fresh, and bruised potatoes rot easily. Storing potatoes in a cool, dark and dry place will help stop them sprouting.

How to Minimize Nutrients Loss When Cooking Potatoes

Potatoes are rich in vitamin C. However, since we do not eat potatoes raw, most of the vitamin C is lost due to the heat of cooking. To minimize the nutrient loss, avoid peeling the skin of potatoes before cooking them. The outer shell provides a good protection against nutritional loss during the cooking process.

According to the Food and Agriculture Organization of the United Nations, boiling unpeeled potatoes results in losses of up to 30 percent of vitamin C, but boiling peeled potatoes can cause losses of up to 40 percent.
