Diseases attack us when our body becomes weak. Some people are very healthy, even after they have an insufficient diet. Many others are ill, even after having the best of foods available.
The reason lies in our eating habits and cleanliness.
When we eat in moderate quantity and follow good cleaning like taking bath every day, cleaning our teeth, and utilizing the energy in an efficient way, we stay healthy for a long time.
While many who overeat, eat indiscriminately, eat multiple times a day, have yellow teeth, and lot of germs in their mouth. Due to this germs make a living in our body, and utilize most of the food we eat. Therefore, we always feel tired and exhausted.
