Apart from the ethical side of things, there are many other pluses to going meat free, even for such a short time. It benefits the environment, is easier on your wallet and is also good for your health."Supporting Meat Free Week or having a few meat-free meals each week is a great opportunity to explore nutritious alternatives," dietitian Samantha Cowan says. "In general, Australians are probably eating too much fatty, salty, processed meat and meat products. This comes with following a Western diet, which is high in saturated fat, salt and sugars from processed, convenience and fast foods," she says. "Choosing a meal based on legumes or lentils, which are low GI and high in dietary fibre and antioxidants, may reduce your risk of bowel cancer and moderate blood-sugar levels. Vegetarians are, in general, less likely to be overweight or obese, and less likely to suffer from the diet-related diseases linked with a Western diet.
