Junk food kills bacteria that protect against obesity, heart disease and cancer
The strong link between the good bacteria, nutrition and general health and the eaten junk food discovered after scientists lived on the meals of a McDonald’s for 10 days in straight.
Eating junk food kills stomach bacteria that protect against obesity, diabetes, cancer, cardiovascular disease, inflammatory bowel disease and autism, recent studies have shown.
The human gut contains about 3500 different species of the microbial, representing about three pounds of weight.
Scientists now believe that a diet based on only a limited number of highly processed foods, rather than those present in a balanced, healthy diet, can wipe out the amount of beneficial stomach flora more than a third.
The discovery could explain why some people on junk food gain weight and others do not, despite eating almost the same amount of fat, sugar, protein and carbohydrates,
The observation was born by the trials of Tim Spector, professor of genetic epidemiology at King’s College London.
He help of his 23-year genetics student son Tom, who agreed to spend 10 days of the fast-food only diet of McDonald’s burgers, chips, chicken nuggets and Coca Cola on.
Tom said: “Before I started fast food diet My father had about 3,500 species of bacteria in my intestines, dominated by the type called Firmicutes.
“Once the diet, I quickly lost the 1300 species, and my gut is dominated by a group called bacteriodetes. The result is that McDonalds diet killed 1300 of good bacteria in my gut species.”
Nearly two-thirds of adult Britons overweight.
However, Professor Spector findings appear to existing research that shows the problem is much to support more complex than just eating too much.
Junk food destroys the abdominal flora also play an important role combat potentially harmful microbes, regulating the metabolism.
They produce in addition to the digestive enzymes for the proper digestion and vitamins D, which are necessary to support the absorption of important minerals such as calcium and iron into the the body.
Bacterial imbalance is associated with an increased risk of developing disorders such as colitis and inflammatory bowel disease, where it appears that autism can be connected to reduce the activity of the intestinal flora.
However, the exact make our microbial populations vary from country to country, but it has been suggested that obesity could be contagious.
University of Colorado in the United States conducted tests that led through the transfer of the bacteria to the mouse obese animals more weight, although the lean beautiful placed in cages in obese they were too thick.
Professor Spector said: “The microbes are listed as bad, but only a few of the millions of species are harmful, and many others are of vital importance for health.
“What is emerging is that changes in our gut microbial community or microbiome, are probably responsible for many of our obesity epidemic and its consequences, such as diabetes, cancer and heart disease.”
Professor Spector oversees the Registry of the United Kingdom of 12,000 twins in the impact of different genetic and environmental factors govern their lives.
The findings are the result of the work of the early British Gut Project, of which he is a founding member.
With the exception of fat and sugar are less important than a healthy diet to ensure that the food that you eat is as varied and natural as possible, said Professor Spector.
His advice chimes with studies of Belgian Beer, garlic, coffee, leek and celery are ideal foods to promote a healthy intestinal flora.
Professor Spector said: “Fifteen thousand years ago our ancestors regularly consumed about 150 ingredients in a week.
“Most people today consume less than 20 different kinds of food, and many, if not most, are artificially refined.
“As junk food does, most of the processed foods will, depressingly, only four ingredients: corn, soy, wheat or meat.”
A spokesman for McDonald’s said: “We have a wide selection of food available in our restaurants and McDonald’s can be enjoyed as part of a healthy and balanced diet.
“We also reformulated our ingredients to reduce salt, fat and sugar, and completely eliminate trans fats from our menus.”
