The role of protein in the body

Protein is key for:

• Building and repairing tissues - including muscle, skin and organs.
• Production of enzymes and hormones - regulating metabolic processes.
• Strengthening the immune system - through the production of antibodies.

A healthy and balanced diet will usually cover your daily protein requirements. However, in some cases, such as athletes or people with a higher physical load, it is possible to supplement them through protein supplements

Can protein be harmful?Is protein healthy?

Studies show that protein is not harmful when the recommended dosage is followed. Excessive protein intake can be associated with certain risks, but these usually relate to extreme and prolonged overload:

1. Stress on the kidneys - the disadvantages of protein: With high protein intake, the kidneys have to process more nitrogen (a by-product of protein metabolism). However, this has not been shown to lead to kidney damage in healthy people.
2. Excess calories: some protein products also contain fats or sugars, which can lead to weight gain.
3. Dietary imbalance: an over-focus on protein can lead to deficiencies in other nutrients such as vitamins or fibre.

Protein and myths

Some concerns about the harmfulness of protein stem from misunderstanding. For example:

• "Protein causes osteoporosis": this myth is based on the assumption that protein increases acidity in the body, leading to bone decalcification. But modern research disproves this - on the contrary, protein promotes bone health.
• "Protein supplements are full of chemistry": High-quality protein products contain high-purity protein and are safe when the instructions for use are followed.

Recommendations for taking proteins

• Balanced diet: try to get most of your protein from natural sources such as meat, eggs, dairy products, legumes and nuts.
• A daily intake of 1.2-2 g of protein per kilogram of body weight is generally recommended for athletes, while the general population can get by with 0.8 g/kg.
• Consult an expert: If you are unsure, consult a dietician or doctor.

Conclusion

Protein is not harmful if consumed in reasonable amounts and as part of an overall balanced diet. Problems can only arise when excessive intake is used or when a medical condition, such as pre-existing kidney disease, is ignored. Protein is an essential element of a healthy lifestyle and proper regeneration of the body, whether from natural sources or dietary supplements.
