It doesn't matter if you eat three packs of potato chips a day. Potato chips are junk food and have no nutritional value. Eating too much will upset your stomach. In addition, the oil content of potato chips is usually around 30%, which is a high-oil and high-salt food. Like other fried foods, long-term consumption is not good for health. At the same time, foods rich in starch may produce acrylamide with different contents after high temperature processing, which can cause cancer.
