Protein is important for growth and repair of bones and other tissue at all stages of life. Fifteen percent of your energy requirements should come from protein. For a woman, that’s 300 calories a day, which you can get from 100g turkey breast, 50g of Camembert cheese or 100g of almonds. The requirement increases slightly for pregnant and breastfeeding women, babies, children and teenagers. The elderly may not need so much.
