Milk and melons should not be eaten together. Both are cooling, but milk is laxative and melon is diuretic, and milk requires more time for digestion. Moreover the action of hydrochloric acid in the stomach causes the milk to curdle. For this reason Ayurveda advises against taking milk with sour fruits, yogurt, sour cream, cheese, and fish. There is a beautiful passage in the Sanskrit literature describing all types of foods and their actions.
Salt also aids digestion, and helps to retain water.
Ghee stimulates agni and improves digestion. Meat gives energy. Kapha is aggravated by milk products. Vata is over-stimulated by beans, dry fruits, astringent and bitter substances. Ayurveda insists that iced water should not be drunk during or after a meal as it slows agni and digestion.
