Many people have a misconception in their dietary structure: eating more staple foods leads to weight gain.Protein consumption is beneficial for health.Nutrition experts believe that scientific dieting should be balanced, with proper proportions of proteins, fats, and carbohydrates.Carbohydrates should provide about 60% of daily energy intake, fats around 25%, and proteins about 15%.Therefore, carbohydrates account for the largest proportion.Each meal should include staple foods, at 30% in the morning, 30% in the evening, and 40% at noon.

A healthy diet includes 400 grams of staple foods per day for men and 300 grams for women, with a greater proportion of tuberous grains.

Following the widely recommended Mediterranean dietary structure,potatoesas the main tuberous food should be consumed at about 170 grams per day, along with 300 to 400 grams of vegetables and fruits daily.Ensure dairy intake is 200 grams per day, and eat more chicken, duck, rabbit, and fish meat,and lesspork.Healthy individuals should consume at least 150 grams of carbohydrates from staple foods daily; it's also unacceptable to completely avoid staple foods as this can lead to the body metabolizing fats for energy.In the absence of carbohydrate intake, the body will produce a large amount of heat through fat oxidation.Ketone bodies produced by fat metabolism may accumulate in the body and cause ketosis.Ketone bodies from fat metabolism may accumulate in the body and cause ketoacidosis.
