Indian food first appeared 8,000 years ago. After trading with the British and Portuguese the diversity of Indian cuisine increased. The earliest Indian food diets included mainly legumes, vegetables, rice, grains, fruits, and dairy products.
The most popular drinks in India include Chai, which is a type of tea made with milk, tea powder, and spices. Another popular beverage is Lassi, which is a yogurt drink that has many different flavors, including mango or other fruits.
