The effects of coffee consumption on health have long been a subject of conflict and uncertainty.Since the 1980s,some have spoken out against coffee as harmful to health,while others have welcomed coffee for its supposed benefits to health.

According to a scientific report,mild coffee consumption,three to five cups per day,can he taken as a healthy dietary pattern,along with other healthful behaviors.The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson's disease.

According to Dr.Donald Hensrud of Mayo Clinic,high consumption of coffee has health risks.Dr.Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body.Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.

According to conclusions from a recent study led by Dr.Gregory Marcus,a doctor from the University of California San Francisco,daily moderate consumption of caffeine,less than 4 cups,is not associated with these issues.

Until the scientific community reaches a general agreement on the effects of coffee consumption on human health,it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.

When informed of these possible health benefits and harms of drinking coffee,Harwood,a high school student stated,"Even though there might be some negative effects of drinking coffee,for the most part,coffee drinking sounds good for health.Not to mention I need coffee to stay awake."

Summer has finally arrived, which means kids are bound for the outdoors. It can be exciting for kids and parents to have a great opportunity to go swimming, picnicking or on adventures. This time of year is also a dangerous time of year as almost half of all injury-related deaths in children occur between May and August. Whether it be in the pool, on bike, out in the sun or in the backyard is always important. Here are some tips to keep the family safe over the summer.

Water Safety

At this time of year, drowning deaths among children skyrocket(飞涨) compared to the rest of the year. Never leave your child alone in the water, even in shallow water. A child can drown in as little as one inch of water. Enroll your children in swimming lessons. Some swim schools offer class for children as young as 6 months.

Sun Safety

We are fortunate enough to live in the Sunshine State, where sun shines year-round. But with all the time you and the kids will be spending outdoors this summer, it’s important to protect yourself. Make sure to use a widely-used sunscreen(防晒霜) that blocks both UVA and UVB sunlight. Cotton clothing has an estimated SPF of only 6, so even if your kids are going out wearing T-shirts and shorts, make sure they are covered up.

Bike Safety

Nothing says summer like a nice neighborhood bike ride. But bikes are not toys and can certainly cause injury. Don’t forget to always wear a helmet. Head injuries are reduced by 85 Percent when riders wear a helmet and other safety equipment like knee and wrist pads. It’s estimated that 75 percent of bicycle-related deaths could have been prevented with bicycle helmets. When riding on the street, make sure kids understand all riding hand signals, ride with the traffic flow and stay as far right as possible.

Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University’s School of Life and Health Sciences. The findings suggest there may be some scientific basis of the "5-second rule" — the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the ‘5-second rule’, until now it was unclear whether it actually helped.

The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: time is a significant factor in the transfer of bacteria from a floor surface to a piece of food, and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said, "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time."

The Aston team also carried out a survey of the number of people who employ the ‘five-second rule’. The survey showed that: 87% of the people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the ‘5-second rule’. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the ‘5-second rule, which our research has shown to be much than an old wives’ tale."

C. The food dropped on the carpet shares the same potential of being polluted with the food dropped on the cement floor.

C. Time D. Space
