So far, chemists have identified only a fraction of the myriad natural compounds in food. And only a fraction of those have been adequately tested for their ability to cause or prevent cancer. The process by which we test a compound to see if it causes cancer—feeding it in relatively high doses to hundreds of laboratory animals—is an important assay, but it is very expensive and doesn't necessarily tell us if the compound will cause cancer in humans. (Different species and individuals differ in their susceptibility to cancer-causing chemicals.) Nor does it tell us if it will cause cancer at the doses found in the diet, or when mixed with all the other compounds in the human diet. Finally, we don't know the precise mechanisms by which many of the chemicals found in food cause or prevent cancer. Even though not all the facts are in, our committee felt it could make several recommendations. Based on the scientific information currently in hand concerning diet and cancer, we feel it is prudent to avoid excess fat, to avoid eating excessive calories each day, and to eat a variety of fresh fruits and vegetables.
It makes sense to wash your fruits and vegetables before you eat them and to limit exposure to pesticides in other ways. If later research finds that these synthetic compounds do increase cancer risk, then the small effort you expend today may in fact protect your health tomorrow.

Characterizing the carcinogenic potential of food is a daunting task. Your diet is an incredibly complex mixture. Even if you ate only raw, organically grown fruits and vegetables, you would take in untold thousands of different compounds each day. As a result of modern agriculture, fertilizer and pesticide residues now commonly appear in food. Preservatives and coloring agents may be added during processing and packaging. And cooking further complicates the mixture—several carcinogens have been isolated from compounds formed when meat is cooked.
The National Research Council asked a committee of 20 scientists, including chemists, toxicologists, oncologists, food scientists, and other experts, to examine the evidence linking diet to cancer. After an exhaustive review, they concluded that the majority of diet-related cancer stems from eating too much fat and too many calories. However, they qualified that conclusion by noting that we have very little information about the roles played by food chemicals in cancer causation and prevention and that much more research must be done.
Through the ages, civilizations have learned to avoid foods containing compounds that are acutely toxic, mostly by seeing people get sick or die soon after eating a particular food. Unfortunately, that sort of shared wisdom doesn't protect against foods that may cause cancer, because the exposure is over many years and there is usually a decades-long latent period before cancer develops.
As cancer rates continue to climb, the link between cancer and diet becomes increasingly important. Cancer causes more than 500,000 deaths in the United States each year. If we had a better understanding of the diet-cancer connection, we could prevent a great deal of suffering and many deaths. Unfortunately, what we currently know is dwarfed by what we don't know:

Natural Carcinogens in Our Food Though the average American diet may cause about one third of all cancers, we don't know exactly what it is in our food that makes cells turn renegade and begin dividing without restraint. While many people suspect the synthetic compounds added to food—things such as pesticides or preservatives or food coloring—natural culprits probably also play a role.
Although synthetic chemicals present in the diet cannot be ignored as potential carcinogenic risks, it seems likely that it is the naturally occurring compounds in our diet, together with excess fat and total calories, that have the greatest effect on cancer causation and prevention.
For decades, research into the diet-cancer connection focused almost entirely on synthetic chemicals added to food, primarily because federal laws demand that food additives be rigorously tested. But interest in the naturally occurring compounds in foods has grown over the past few years, as researchers have learned that some of these compounds act as carcinogens (i.e., cause cancer). Known natural carcinogens include caffeic acid, found in a variety of plants, and aflatoxins produced by fungi that infest nuts and grains.

shais look Pakistan main Qadiani bhi hain ager religion pass port per mention nahin ho ga to woh Pakistani pp ka use ker k Saudia aur KHana kaba tak enter ho saktay hain aur phir Pakistan(muslims) k naam per woh kuch bhi kernay ki koshish ker saktay hain kissi ko yeh to pata nahin chalay ga k woh muslim tha ya non muslim kahlaye ga to Pakistani hi log yeh bhi kah rahay hain k sari duniya main kahin bhi PP per religion mention nahin kya jata to yahan kyun
lakin main nay yeh bhi parha hai k saudia k AKKAMA aur ID card per bhi religion mention hota hai ab aap hi kahi kya yeh sahi hai
frnds plz apnay answers yes / no k saath reason bhi batain
