Modern people pay more and more attention to health and fitness exercise. Because there is not much time at ordinary times, going to the fitness room has become a popular choice. Fitness needs to digest the body's heat and energy. If it is not supplemented in time, it will make the body lose fat and water continuously, and will not play a role in strengthening the body. At the same time of exercise and fitness, muscle protein powder should be supplemented in time to supplement calories and nutrition for the body. So how to eat is useful? Methods/Steps Because different brands of protein powder have different nutritional components, they should be taken according to the recommended intake, and the general instructions should be marked. In terms of dosage, eating less can not achieve the expected effect; Eating too much will cause waste or side effects. When eating protein powder, you can't eat on an empty stomach. If you eat protein powder on an empty stomach, it will be consumed as a general "hot food", wasting valuable high-quality protein sources. Therefore, if you need to feel hungry after fitness, you can eat some other foods before or at the same time as eating protein powder. If you eat protein powder, you can add it to milk, soybean milk, cereal, malt extract and other foods to eat together. Optimum edible temperature of protein powder. Because white powder contains many active substances with special physiological functions, they are all afraid of heat, and once heated, they will lose their activity, thus greatly reducing their biological potency. Therefore, whey protein powder must not be cooked or burned, but can only be dissolved (mixed) in water, porridge, malt extract and other foods below 40℃, and can also be eaten as a cold drink. Pay attention to protein powder when adding seasoning. Protein powder can be added to various foods, such as sweet with sugar and salty with salt, but not too much. Because too much sugar and salt intake is not good for human health. Also, don't add monosodium glutamate to eat protein powder, because protein powder itself has a certain flavor, and the proportion of amino acids in whey protein powder is better, and monosodium glutamate is a component of monosodium glutamate, which decomposes glutamic acid after metabolism in the body. Adding monosodium glutamate to protein powder is tantamount to gilding the lily. Protein powder should not be eaten with acidic drinks, such as apple juice and other drinks containing organic acids. When it meets protein powder, it will form a clot, which will affect digestion and absorption. Precautions. Children who are too young should not eat protein powder. Protein ingredients are not suitable for young children and are not conducive to children's digestion and absorption. It is likely to cause vomiting, diarrhea or allergies after eating.
