Protein in potatoes, no matter its nutritional value or health care function, can make soybeans sigh. From the point of view of nutrition, the nutritional value of 1 kg potato is equivalent to about 2 kg apple. The high nutritional value of potatoes makes American nutritionists assert: "As long as you eat whole milk and potatoes at every meal, you can get all the nutrients your body needs. Known as the "second bread" of mankind.

Beef is recognized as a high-quality and high-protein food, and its nutrients are easily absorbed by the human body. It has more protein than pork and mutton, but less fat, so it is also deeply loved by people.

The human body's nutrient absorption of different foods is fast or slow, which mainly depends on the digestion and absorption function of the stomach, and is also determined by some properties of similar foods. In real life, potatoes and beef need different concentrations of gastric acid during digestion, which will inevitably prolong the stay time in the stomach, thus delaying the digestion and absorption time in the stomach and failing to achieve the effect of instantaneous distribution of nutrients. If this continues, it will lead to gastrointestinal dysfunction. Many times, when we eat potatoes and beef, we will feel flatulence and discomfort, and this factor is included. Therefore, although the roast beef with potatoes is delicious, we have to bear the pain and give up what we want.
