Talking about fruits, vegetables and diseases
Five times a day is "no good" and five times a day has no effect.
According to a new scientific research, one of the most common beliefs about health and nutrition in Britain has been found to be untrue.
For years, British people have been advised to eat at least five kinds of food every day? That is to eat five kinds of fruits or vegetables every day to improve their health and reduce the possibility of illness, especially cancer.
The World Health Organization first put forward this suggestion in 1990, saying that "five servings a day" diet can prevent cancer and other chronic diseases.
Since then, this proposal has become the pillar of public health policies in many developed countries, such as Britain, where the population eats a high proportion of junk food.
Many health campaigns have promoted this suggestion. In fact, many food packages in Britain explain how these contents will form part of your five servings of food a day.
However, a study of 500,000 Europeans from 10 different countries refutes a widely held view that up to 50% of cancers can be prevented by increasing public consumption of fruits and vegetables.
On the contrary, this study, led by researchers from a famous medical college in new york, estimated that only 2.5% of cancers could be avoided by eating more fruits and vegetables.
It seems that the key to avoid cancer is to have a comprehensive and healthy lifestyle, including not smoking or drinking too much, exercising and avoiding obesity.
However, medical charities have publicly reminded people that diet is an important factor in maintaining health, and even a 2.5% reduction in cancer is a positive step.
Cancer Research UK said: "It is still a good idea to eat five servings a day, but remember that fruits and vegetables are part of a larger lifestyle puzzle."

The deadly Legionella
Legionnaires' disease is a serious and sometimes fatal pneumonia. Legionella is caused by Legionella infection. Legionella naturally exists in the environment and breeds in warm water and warm and humid places. The artificial water system sometimes provides an environment for the large-scale reproduction of Neisseria legendra. These artificial systems include showers, hot spring pools, fountains and air-conditioned cooling towers. People usually get legionnaires' disease by inhaling the fog from the water polluted by Legionella.
It is estimated that 8,000 to18,000 people in the United States suffer from Legionnaires' disease every year. Some people may be infected with Legionella with mild symptoms or no disease at all. Legionnaires' disease patients usually have fever, chills and cough, which may be dry or may produce phlegm. Some patients also have muscle pain, headache, fatigue, loss of appetite and occasionally diarrhea. It takes 2- 10 days for symptoms to appear from Legionella infection. In most cases, symptoms begin after 5-6 days. Legionnaires' disease is treated with antibiotics such as erythromycin. The sooner you start treatment, the better the effect.
The first known outbreak of legionnaires' disease was in Philadelphia, USA, 1976. A total of 22 1 person was infected and 34 people died. Most of the dead are veterans, which is the name of the disease. The second outbreak was in Staffordshire Hospital in England1985; A total of 10 1 people were infected and 28 people died.
Legionnaires' disease is a very serious and sometimes fatal pneumonia. Legionella is caused by Legionella, which is produced in the natural environment and spreads in warm water and hot tide. The artificial water supply system can sometimes provide a living environment for the mass reproduction of Legionella. These systems include showers, mineral pools, fountains and cooling towers for air conditioning equipment. People usually get Legionnaires' disease by breathing water mist from water contaminated by Legionella.
It is estimated that 8000 ~ 18000 people in the United States are infected with Legionella every year. Some people infected with legionnaires' disease show mild symptoms or even no signs of illness at all. Legionnaires' disease patients usually have fever, chills, dry cough or expectoration. Some patients also have muscle pain, headache, fatigue, loss of appetite and occasional diarrhea. The incubation period of this disease is about one incubation period. Many cases show that it takes 5~6 days for symptoms to appear. Legionnaires' disease can be treated with antibiotics such as erythromycin, and the earlier the treatment, the better the effect.
The first known outbreak of legionnaires' disease was in 1976 in Philadelphia, USA, and 22 1 person was infected with the disease, among which 34 people died. Because most of the dead were members of the Legion, they were called Legionnaires' Disease. The second outbreak of the disease was in Staffordshire Hospital in England from 65438 to 0985. This time 10 1 28 people died.

? It's time to be 25 today, okay? Young women in the United States have left college and are trying to start a good career, trying to repay student loans, trying to find someone who wants to have children with them, and trying to climb the housing ladder. ?
? A 25-year-old contemporary young woman has just graduated from college and started her career. They are busy paying off student loans, finding boyfriends and trying to buy a house. ?
Dr Lockwood also severely criticized fertility treatment as a feasible choice for women over 40. ? The depressing reality is that once you are 40 years old, it is absolutely impossible for IVF to work with your own eggs. She said. ? We will make, let alone encourage, patients to pay for an elective surgery with less than 5% job opportunities, and that may be Dr. Lockwood? In the eyes of Americans, many people who want to be parents may be happy to seize these opportunities.
Dr Lockwood also criticized the practice of promoting infertility treatment to women in their forties. ? The truth is cruel. If you are over 40 years old, the chances of successful in vitro fertilization of eggs are very low. She said. ? Who will allow or even encourage patients to undergo elective surgery with a success rate of less than 5% is Dr. Lockwood's opinion, but there are still many parents who hope that their children will be willing to seize these opportunities.
