GOOD NUTRITIONAL health calls for an ade quate intake of all the nutrients and can only be achieved by consuming a wide variety of foods. Some of our modern 'diseases of affluence' are blamed on excessive intakes of fat and sugar and salt with inadequate dietary fibre, consequently current nut ritional advice is that everyone should change his diet accordingly. Since meat is a major contributor of satu rated fat to the British diet it is being recommended that leaner carcasses should be produced, that less meat should be eaten and replaced by poultry and fish, and that the fat content of meat products should be reduced.
