Other nutrients

These nutrients aren't used on the front of pack labelling but you may see them on the back of pack nutritional information.

Protein (RI: 50g)

Proteins are the major functional components of all the cells of the body and are essential for growth and repair.

Each gram of protein provides 4 calories. Proteins are found in many different foods. Animal sources of proteins include: meat, poultry, fish, eggs, milk, cheese and yogurt. Plant sources include: pulses (such as beans or lentils), grains, nuts, seeds and cereals.

Protein should contribute 10-15 percent of the total daily energy intake (2000 calories). This amount is essential to maintain the normal growth and repair of body tissues. Some amino acids (that make up proteins are essential in the diet as the body cannot make them).

The Reference Intake for protein is 50 grams.

Carbohydrates (RI: 260g)

Carbohydrates (comprised of sugars and starches) are an important energy source and also contain B-vitamins. They form the biggest part of the diet, making up around 50-55 percent of daily energy intakes.

Sources of carbohydrates include: Fruits, vegetables, grains, cereal products and milk and milk products.

Sugars and starches are the main carbohydrate sources of energy. They provide four calories per gram.

Information on total carbohydrate (and how much of this is sugars ) is mandatory and will be displayed on the nutritional information labelling (usually found on the back of pack).

Fibre contains fewer calories per gram but is still classified as a carbohydrate. It has many beneficial effects on health, such as preventing constipation and improving blood glucose levels. Intakes of fibre in the UK are below recommendations.

Labelling fibre is voluntary but many companies do add this information. If it is present this will also be in the nutritional table with the other nutrients.
