Time and meals

According the Vedic knowledge it is extremely important to eat certain products at certain time or I would say not to eat certain products at certain time. Fruits are governed by the Sun, thus, they must be eaten in the first part of the day when the Sun is active during several hours after the meal to have enough time to digest it. For example, at 6-8 o'clock for breakfast. Vegetables are governed by the Moon, thus must be eaten for lunch at 11:30-13:30 and dinner at 17-18. They recommend cooked vegetables for dinner because fresh food gives too much energy, not necessary in the evening as it prevents us from falling asleep. It is recommended not to eat after 20.
From the personal experience of raw foodists they can eat at any time of the day without feeling discomfort in the stomach, and some 5-6 hours of sleep is really enough for them.
