"One of the keys to happiness is bad memory" - Rita Mae Brown
But another way is to be physically healthy.
In 1988, I moved from a 'strict' non-vegetarian to a vegetarian. But I remain a small time 'foodie', primarily due to my very preferences. It gets difficult while travelling on work. Moreso, outside India. Yes, the options limited. But at the same time, food generally becomes less important in life, which I feel is good on a spiritual sense. It is important to ensure we eat the right food...
Hence, sharing what I found in Alva Carpenter's Slimline column:
Vegetarians should aim to eat:
5 servings of fruit and vegetables
6 servings of cereals and grains, e.g. rice, pasta, muffin, breakfast cereal
2 serving of legumes nuts and seed- good sources of protein e.g. chickpeas, kidney beans, tofu, quorn, lentils, brazil nuts, pumpkin seeds
2-3 servings of milk and milk products or alternatives e.g. cow’s milk, soy milk, cheese, yoghurt
6-8 glasses of water
