Protein

Proteins are large, complex molecules made up of amino acids, essential for building and repairing tissues in the body. They are found naturally in a wide range of foods, including meat, fish, dairy, legumes, nuts, and seeds. In food manufacturing, proteins can be extracted from various sources, such as plants (like soy or pea) or animals (like whey from milk).

Manufacturers add protein to foods to increase their protein content, catering to consumer demand for protein-rich products. It can also act as a binder, emulsifier, or texturiser, improving the mouthfeel and structure of items like protein bars, powders, and meat alternatives. Protein isolates and concentrates are commonly found in sports nutrition products, baked goods, and dairy-based items.

Protein is a macronutrient essential for human health, not classified as a food additive in the UK. The UK government's Eatwell Guide recommends including a variety of protein sources in the diet. While essential, excessive protein intake is not generally recommended without specific needs, and the NHS advises a balanced diet. There are no specific regulatory limits set by bodies like EFSA for protein as a nutrient, as it is a fundamental component of food.
