Tea is one of the most popular beverage in the world. Tea is indeed rich in antioxidants and has an array of health benefits. It increases body's metabolism and helps us to loose weight. However if one feels like utilizing all the benefits of a healthy cup of tea, then it is always better to drink unsweetened black tea or green tea just brewed with water. As the calories in such a tea is just 2 to 2.5 calories per cup, which is a negligible value. But the tanins in the tea also make it bitter in taste and several people dislike the bitterness hence add milk and sugar to make it more appealing to their taste buds.
However consuming a cup of tea with milk and sugar is not a good idea. Though the milk may add in some calcium and vitamins it also adds fat content to the tea, which also increases the calorific value of the tea. The lactose in the milk, which is a carbohydrate, also adds the calorific value further more. The calcium in the milk may adversely affect the tannins in the tea, making them less effective. Sugar on the other hand causes further problems on its own, a teaspoon of sugar contains about 15-16 calories. Therefore the total calories in the tea is increased to 25 - 30 calories per cup from 2-2.5 calories per cup, with the addition of milk and sugar. Now that is a huge difference and drinking such a tea more than two times a day is certainly not good for health.
It is also important to buy a good brand of tea as cheap brands may be made adulterated with waste from tea packing industries and may also contain artificial taste enhancers and illegal colours, which are harmful to the body. it is also better to avoid pre mixes and ready to drink, packed teas, as they may be loaded with sugar and other chemicals.
