The Balance of Good Health

‘The Balance of Good Health’ is the Food Standards Agency’s guide to a healthy diet. The size of each segment, as illustrated in the figure opposite, represents the proportion that each food group contributes to a healthy diet.

Most of us could do with eating more fruit and vegetables and cutting right back on fatty and sugary foods - not to mention big portions!

But the emphasis is really on enjoying more of the foods that suit you as well as providing protection and nourishment for your body. So choose a variety of foods from each of the different groups each day:

  • At least five portions of fruit and vegetables – fresh, frozen, canned, dried and juiced all count.
  • Healthy energy foods like bread, pasta, rice, potatoes, cereals and noodles as part of meals; include satisfying wholegrain types.
  • Two to three servings of milk and dairy products (or calcium-fortified soya alternatives). A serving could be 200ml/1⁄3 pint of milk, a small pot of yoghurt or 30g/1oz (small matchbox sized) piece of cheese.
  • Two to three moderate servings of protein-rich lean meat, fish, chicken, eggs, pulses, tofu, nuts or seeds. A serving could be 90g/3oz (size of a deck of cards) of cooked meat, a medium fish fillet, two eggs (up to six eggs a week), four to five tablespoons of beans, two tablespoons of nuts or seeds.
  • Modest amounts of unsaturated oils, such as olive, rapeseed or soya oil and spreads made from them, fatty foods, sugary foods and drinks.

Five key tips to boost your nutrient intake

  • Have a bowl of fortified breakfast cereal with fruit or juice every day.
  • Vary the colours of your daily fruit and vegetables for an optimal mix of vitamins and body-protecting antioxidants. Antioxidants work to mop up excess ‘free radicals’ that whiz around the body, with the potential to damage healthy cells and may contribute to a wide range of health problems, such as heart disease, cancer, cataracts and lung disorders.
  • Don’t skip carbohydrates, but do try to include wholegrain breads, cereals, and crackers. Satisfying and nutritious, eating three or more servings daily has been linked to lowering the risk of heart disease, cancer and diabetes by up to 30%, thanks to their nutritional benefits. A serving could be a slice of wholemeal bread, a bowl of porridge or wholewheat cereal, two to three oatcakes or rye crispbread, three tablespoons of cooked brown rice or wholewheat pasta.
  • Enjoy fish at least twice a week and make one portion an oily fish (salmon, sardines, mackerel, trout, pilchards), as these contain omega-3 fats that are beneficial to the heart and immune system
  • Remember dairy foods. Low fat milk and yoghurts have just as much bone-building calcium.Why not try a daily bioyoghurt or probiotic; they help to promote a healthy balance in the bowel.
