Food

In all circumstances they should conduct themselves with moderation; if the meal be only one course this is more pleasing in the sight of God; however, according to their means, they should seek to have this single dish be of good quality.

Bahá’u’lláh, Lights of Guidance, p. 294

At whatever time highly-skilled physicians shall have developed the healing of illnesses by means of foods, and shall make provision for simple foods, and shall prohibit humankind from living as slaves to their lustful appetites, it is certain that the incidence of chronic and diversified illnesses will abate, and the general health of all mankind will be much improved. This is destined to come about.

‘Abdu’l-Bahá, Lights of Guidance, p. 295

But eating meat is not forbidden or unlawful, nay, the point is this, that it is possible for man to live without eating meat and will be strong. Meat is nourishing and containeth the elements of herbs, seeds and fruits; therefore sometimes it is essential for the sick and for the rehabilitation of health. There is no objection in the Law of God to the eating of meat if it is required. So if thy constitution is rather weak and thou findest meat useful, thou mayest eat it.

‘Abdu’l-Bahá, Lights of Guidance, p. 295

But man begins little by little to accustom himself to poison, by taking a small quantity each day, and gradually increasing it, until he reaches such a point that he cannot live without . . .

But now coming to man, we see he hath neither hooked teeth nor sharp nails or claws, nor teeth like iron sickles. From this it becometh evident and manifest that the food of man is cereals and fruit. Some of the teeth of man are like millstones to grind the grain, and some sharp to cut the fruit. Therefore he is not in need of meat, nor is he obliged to eat it. Even without eating meat he would with the utmost vigour and energy. For example, the community of the Brahmins in India do not eat meat; notwithstanding this they are not inferior to other nations in strength, power, vigour, outward senses or intellectual virtues.

‘Abdu’l-Bahá, Lights of Guidance, p. 294

God has created all men in such a manner, and has given them such a constitution and such capacities, that they are benefited by sugar and honey, and harmed and destroyed by poison.
