Dr Aastha Khungar, Head of Nutrition and Dietetics at Max Hospital, Mohali (India), said protein powder can be a convenient and effective protein supplement solution for busy people or those with high protein requirements.
However, it should not completely replace natural foods and needs to be used wisely to avoid unwanted side effects.
Advantage
Convenience: Protein powder is easy to use and carry anywhere. It's a quick way to supplement protein when there's no time to prepare a full meal.
Support muscle recovery: Protein powder helps the body recover quickly after exercise, promotes muscle regeneration and reduces fatigue.
Easy protein source: Protein powder is a rich source of protein and is easily digestible, without the need to eat a lot of food.
Aids in weight loss: Protein supplementation can help increase feelings of fullness, which can help reduce cravings and control weight.
Easy to combine with other foods: Protein powder can be combined with smoothies, cereals or other dishes, increasing nutritional value without changing the flavor much.
Disadvantages
Digestive side effects: Some protein powders, especially whey protein, can cause bloating, indigestion or diarrhea, especially for people who are intolerant to lactose or artificial sweeteners found in the product.
Contains filler ingredients: Some protein powders may contain sugar, artificial sweeteners, preservatives, or other ingredients that are not good for your health if used long term.
Lack of other nutrients: Protein powders do not provide the full range of other important nutrients such as vitamins, minerals, fiber, and healthy fats that natural foods like meat, fish, beans, and nuts can provide. Therefore, relying solely on protein powders can lead to nutritional deficiencies.
Can put pressure on the kidneys: When you consume too much protein, especially from protein powder, your kidneys have to work harder to filter out excess waste. This can put stress on your kidneys and increase your risk of kidney stones, especially for people with kidney problems.
High Cost: Compared to natural foods, protein powders can be quite expensive, especially if you use them regularly.
Dr Rakesh Kochhar, Head of Gastroenterology at PGI, Chandigarh (India), emphasized that the quality of soy protein concentrate products can affect hormone levels in the body.
“A recent study found that some supplements may contain heavy metals such as lead, arsenic, cadmium, mercury, and Bisphenol-A (BPA), a carcinogen. These toxins may come from the manufacturing process,” notes Dr. Rakesh Kochhar.
