Protein powder should not be consumed excessively! Overconsumption may harm the kidneys. For fitness enthusiasts, moderate protein powder supplementation after high-intensity exercise can promote muscle growth. However, without intense physical activity, excessive protein supplementation is unnecessary and may instead increase the burden on the liver and kidneys.
Common protein powders are primarily soy-based, classified as plant proteins. These differ from human proteins; animal proteins are more similar to human proteins, hence high-quality protein typically refers to animal sources. However, both animal and plant proteins must be broken down in the body for absorption. During this process, animal proteins produce fewer toxins, while plant proteins generate more toxins. The more plant protein consumed, the greater the toxin production.These toxins must be excreted by the kidneys, placing additional strain on them. Consequently, individuals with impaired kidney function should avoid protein powder entirely.
Even those with mild nephritis and normal kidney function should refrain from consuming protein powder. In reality, a balanced daily diet provides sufficient protein intake, making supplemental protein powder unnecessary. Only individuals with poor digestion or those prone to weight loss may benefit from appropriate protein powder supplementation.
Who is protein powder suitable for?
1. Individuals with generally normal diets but experiencing increased protein consumption due to illness, such as those recovering from fractures or burns.
2. Vegetarians, especially strict vegans, who can use protein powder to address insufficient protein intake, though it cannot fully replace dietary sources.
3. Individuals unable to consume high-quality protein foods, such as pregnant women who experience nausea at the smell of meat. Additionally, patients with acute hepatitis often suffer from significant nausea, vomiting, and loss of appetite. When needing to supplement with easily digestible, high-quality protein that doesn't burden the liver, protein powder can be used appropriately.
4. Individuals engaged in muscle-building exercises.
Where to get protein: Food over supplements?
1. Soybeans
Soybeans boast exceptionally high protein content—three times that of eggs. They can serve as a staple food or be stir-fried, making them an excellent protein source.
2. Dairy products
Dairy is rich in high-quality protein. Milk, for instance, contains up to 3% protein and all eight essential amino acids. It also provides abundant B vitamins and calcium. Consuming 300 grams daily—or an equivalent amount of other dairy products—is highly beneficial for weight loss.
3. Eggs
Eggs are exceptionally rich in protein and offer numerous other nutrients. They pose no risk of excessive cholesterol intake, aid lipid metabolism, and help lower blood lipids.
4. Fish
Compared to other meats, fish is rich in unsaturated fatty acids and low in calories, making it an ideal choice for weight loss. In fact, fish also boasts high protein content. Consuming 75-100 grams daily of white fish like cod or shrimp is perfectly adequate.
5. Meat
While many dieters avoid meat altogether, common options like chicken, duck, beef, and lamb are excellent sources of high-quality protein. Consuming 50-70 grams daily significantly aids muscle growth. Opt for leaner cuts whenever possible, such as skinless chicken breast or lean beef.
