The fact that diet works is confirmed by its effectiveness in people who follow it for a long time. Let's see practical examples of different diets followed by the people around the world and its implications on their health, fitness and long life.
The best example is America. People here are addicted to processed food whether it be cornflakes, chips, burgers, sausages and diary products like yoghurt. The results are clearly seen in their state of health.
About 70% of the adult population has problems with obesity, stomach ailments and sluggishness. The rates of heart attack and cancer are rising alarmingly. Diabetes is very prevalent as is high blood pressure.
Processed food is the poison for your body because it is denaturalized and lacks any trace of water content. It is also high in salt, sugar and preservative chemicals which can induce cancer. The life expectancy is low, expect in cases where the patient is aided surgically to live more.
Most of the Asian population is known to follow this diet. There is also an intake of non-vegetarian food along with rice in certain communities.
The percentage of obesity is lower compared to the west but people do suffer largely from diseases like diabetes, blood pressure and heart attacks. The primary reason who be the intake high amounts of oil, diary products, sugar and salt in their diet. Cooked food requires the use of oil and salt and condiments to a great extent which harms the digestion and body health.
Life expectancy is not high.
A few tribes spread across the world are still in touch with their natural way of eating fruits and vegetables in the raw state along with some rice and pulses occasionally. The best examples is the Honzo Tribe located along North-West cold mountainous region of Pakistan.
The life expectancy is as high as 100 years or above in most of the people. There were no traces of diseases like diabetes, blood pressure or cancer. Kidney stones are unheard of and the population is lean and well muscled. Even old people are seen to have thick and lush hair. They have strong teeth and their immunity survives the worst spells of cold weather.
The question of does the fruit and vegetable diet really work gets answers by the state of health enjoyed by the Honzo tribe. After looking at this practical example, is there really a need to speculate further on the effectiveness of a diet rich in raw fruits and vegetables?
