Reason for asking:
I'm having digestive issues with eating meat, and I wish to switch to a vegetarian diet to see if it'd help.
I've already tried a vegetarian diet multiple times (mostly the veggies here: spinach, bitter gourd, potato, tomato, onion, beetroot, bottle gourd, brinjal, beans, cabbage, okra, capsicum, carrot, cauliflower, drumstick, elephant yam, garlic, ginger, ivy gourd, green banana, green gram, green banana, tapioca, yam), but it has been insufficient in giving me the necessary muscle strength for sustained work (specifically the extraocular muscles, and I notice this very easily due to having suffered chronic eye strain for a decade). However, when I eat chicken meat, I get the necessary muscle strength.
I read in a newspaper that although plant diets contain similar proteins as meat diets, the range of proteins offered in a meat diet are much higher and in greater concentrations, so it's necessary to incorporate a wider variety of plants/veggies in the diet to be able to adequately make up for the nutrition that meat gives. So if somebody has actually discovered such a requirement, then is there a table or any information that lists out exactly which set of vegetables to consume and in what quantity, so that it'd make up for a meat-based diet?
