Eat Less and Live Long

Our Great Prophet Hazrat Muhammad Mustafa Ahmad Mujtaba (PBUH) has said had said nearly 1500 years back that "stop eating the meal when you are still hungry and need some 3-4 mouthfuls more. Eating a bit less will keep you healthy." I think,though the residents of the Japanese city Oki Nawa would neither be knowing about this Hadit nor they are Muslims, but they act upon this saying of The Great Prophet and live a healthy life for more than hundred years. They never think of delicious meals nor need special meat or vegetables. They just take simple foods but they have the tradition of eating less and are nearly half hungry when they stop eating. It has been been proved in Scientific Study that these people of free of Cancer, Hypertension and Diabetes. They take fish and Tofo having proteins THey do not know about protein), brown rice, cereals in the form of barley that has carbohydrates, they also take vegetables and fruits and other such natural foods that have high quantity of water. They never eat fats and boiled meat, so they live natural life.
On the other hand there are people in the world who eat so much that in the last their stomach refuses to take more. This is not only in under developed countries , but even in USA, England and other wealthy states. According to WHO, the world population at this time is 6.6 billion and and every night 1.2 billion sleep hungry and with out taking any thing.The people in many countries are suffering from many diseases due to eating more and wasting the cooked foods more than they eat. In England, 0.67 million ton cooked food worth 10.2 pounds is wasted or thrown away annually.Similarly, every British family wastes on the average surplus meals of 250-400 pounds annually. In the USA, 100 billion lbs of food, including fresh fruits, vegetables, and cereals are thrown away. The restaurants in the USA waste ( throw away)6000 tons cooked foods daily.
One can imagine, on one side many people are dying of hunger or suffering from diseases due to malnutrition and on other hand , how much food is being wastes by the human beings in this world.
