The nutritional experts have been conducting the research about the relationship between cola and roast meat. They think that the simultaneous intake of roast meat and cola can seriously affect the physical health of the human body. The caffeine contained in cola can rapidly accelerate the activities of carbon ions resolved by the smoked food, which can cause the loss of calcium inside the human body. When the calcium is lost seriously, the bone cells will be excessively produced inside the human body to finally cause cancer in the bones. 

Although the research result needs to be proved further, the intake of roast meat can really cause many problems about health. When people are barbecuing the food, the carcinogenic substances like dioxin and benzopyrene in the smoke can enter the food to destroy the nutrients like vitamins and amino acid contained in the food, which can seriously hurt the human body at the same time. When the vitamins, amino acid and protein are destroyed by the toxic substances, the absorption of such nutrients can be seriously affected. The carcinogenic substances can also enter the human body through skin, respiratory tract and digestive tract to induce cancer. What’s more, parasites can be easily infected inside the meat, which can increase the risks of getting cerebral cysticercosis for the human body. The excessive intake of roast meat can also affect the eyesight of teenagers to cause myopia. Women can not always eat too much roast meat, as the risks of getting ovarian cancer and breast cancer inside the female body can be terribly increased. In addition, the raw material for barbecue is usually of poor quality and the production process is also dirty. The spices like pepper and chili can stimulate the gastric and intestinal peristalsis and the secretion of digestive juice, which can probably hurt the mucous membrane of digestive tract and affect the balance of physical constitution. Therefore, people should avoid such food in daily life as far as possible.

When people are eating barbecue, they should also eat some fresh vegetables and fruits to alleviate the danger. Fresh vegetables like cabbage and tomato and fresh fruits like apple and lemon contain high content of vitamin C and vitamin E. Abundant vitamin C contained in vegetables and fruits can decrease the production of nitrosamine and vitamin E can effectively resist oxidation. Such a kind of dietary collocation can effectively reduce the harms caused by the roast meat.
