Scientists in the USA found that going on a specific low-carb diet is very useful in winter.
Such a system protects man from influenza, which is one of the commonest diseases of the cold cays of the year.
They say that diet resembles one set by Dr. Atkins, a leading British dietarian.
The suggested diet contains a high rate of fats which stimulate the immunity system of the human body.
So it is able to fight the viral infection.
This discovery comes as a result of a study conducted on two groups of rats.
The animals were nourished on various meals then they were exposed to a strong strand of the virus that causes influenza.
Symptoms of the disease appeared within four days on the rats that ate higher rates of carbs, meanwhile, the animals that ate higher rates of fats (90%) of the volume of a meal (9% of protein) and 1% only carbs fight the virus effectively.
Only half of the second group gave in to the virus.
Akiko Eusaki, professor of immunity at Yale University, USA, said that rats ate low-carbs increased rate of white blood cells in their lungs so they could fight the virus successfully.
Those cells called Gamma delta T-cells.
Those cells work to improve defense lines in the lungs to ameliorate defending mechanisms against the invading virus.
Team members assure that this experiment could be widened to reach methods to protect men against influenza, a deadly epidemic in the 21st century.
Influenza, commonly known as the flu, is an infectious disease caused by an influenza virus. Symptoms can be mild to severe.
The most common symptoms include high fever, runny nose, sore throat, muscle pains, headache, coughing, and feeling tired.
These symptoms typically begin two days after exposure to the virus and most last less than a week.
The cough, however, may last for more than two weeks in children, there may be diarrhea and vomiting, but these are not common in adults.
Diarrhea and vomiting occur more commonly in gastroenteritis, which is an unrelated disease and sometimes inaccurately referred to as “stomach flu” or the “24-hour flu”. Complications of influenza may include viral pneumonia, secondary bacterial pneumonia, sinus infections, and worsening of previous health problems such as asthma or heart failure.
