"Eat less intensively reared meat". Tim is right but it is worse! The intensively fed meat animal is fed in stalls, so they get no exercise: so muscle (meat) degenerates. They are fed high energy, growth promoting diets for weight gain. How do you gain weight? You put on fat. So FAT infiltrates between the fibres of the degenerating muscle (meat). Look at the stuff in the Supermarket and you will see the white FAT inside - inside mark you - the muscle (meat). That fat is thrombogenic and atherogenic.
Meat should be RED not WHITE. So at the end of the fattening process, the consumer is presented with more fat calories than protein. Huge amounts of carcass fat going into a variety of convenience foods. The naturally reared animal living on grass, herbs, sedges and browse provides more energy from protein than fat. Moreover feeding on cereals and protein does not provide the omega 3 fatty acids found in the naturally reared animals. Cereal is all omega 6. To make matters worse, chickens that used to be a lean, omega 3 rich food, is no longer for the same reason. They used to scratch for food in the grass and undergrowth, ate a lot of foods with a green starting point – grass, herbs, snails etc. – so a chicken was a low fat product rich in the omega 3 fatty acids that you need for the heart and brain. Again because of cereal feeding nearly 24 hours a day in a confined space (again no exercise) there is now more than 3 times the energy coming from fat in the intensively reared chicken compared to protein. There is a massive waste of energy in this production system for ox and poultry meat production and the end product is a nutritional distortion:
For example, chicken is no longer a good source of omega 3 fatty acids with the levels in the meat being less than a quarter pf what it was in the early 1970s and now rich in cereal omega 6 instead. (see Wang Yet al (2009) Modern organic and broiler chickens sold for human consumption provide more energy from fat than protein. Public Health Nutr. 4:1-9)
What do the doctors tell us to do? Get exercise, reduce bad fats, reduce high energy foods, and eat a balanced diet to avoid weight gain. The intensive animal production system does the opposite. Exercise is denied. The animals are fed on high energy weight promoting diets and even genetically selected for such weight gain. For reasons of energy conservation, nutrition and health, it is best to avoid such products
