Which you will, with no problem - a vegetarian diet is a very varied and nutritious one. Recent medical research has shown that vegetarians live healthier lives than meat-eaters, and have less chance of getting certain cancers or of suffering heart conditions. Obesity and high blood pressure are far less common, so are various forms of diabetes, and anecdotally vegetarians say that they FEEL very healthy and full of energy, and that they feel the effects of ageing less.
Most plant foods contain it.
Excess protein in the body can cause diseases such as osteoparosis and poor kidney function, and even certain cancers. It is claimed that a vegetarian diet has the advantage over a meat-based one, in that its protein content is adequate but not excessive. An average vegetarian diet will meet daily protein requirements. The soya bean is a high quality protein and all soya products such as soya milk and tofu are extremely good sources. Chick peas and lentils have a high protein content, so do baked beans and muesli, nuts and seeds.
