First of all, I want to say that the first impact on human health is that eating too many potatoes will make people fat. Because potatoes are a kind of food rich in starch, and starch, as we all know, is also a kind of sugar. If starch accumulates too much in the human body, it will eventually turn into fat. And we either eat rice or pasta every day, which can ensure the human body's daily intake of starch. And people eat a lot of potatoes every day, so eating too much starch will naturally make them fat. So we shouldn't eat potatoes every day.
The second is that eating too much potatoes will raise blood sugar, because potatoes contain a lot of starch and will eventually be forwarded to glucose. Then there will be too much glucose in the human body. If there is too much glucose, people's blood sugar will rise. And high blood sugar is not a good thing. You can't eat potatoes every day to stabilize blood sugar. Especially for diabetics, it is best not to eat potatoes.
The above is what I know about the effects of eating too many potatoes on the human body.
