1 . One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn’t want to waste it, so she cuts off the moldy part and eats the rest. Is it safe to do this?
Mold can grow on almost all kinds of food. It is usually green, white, black or gray. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat.
If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains (含有) water, which allows mold to grow easily below its surface. Bacteria (细菌) can also grow along with it.
But it’s easy to remove mold from hard food because mold can’t grow very deep inside this kind of food. According to BBC news, you should cut about 2.5 cm around and below the mold to remove it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should, still throw it away.
Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well.

2 . Doctors across the world tell us it is necessary to eat lots of vegetables to keep the heart healthy. But a new study in February, 2022 suggested eating a lot of vegetables may not greatly cut down the risk of heart problems.
The study is from universities in Oxford and Hong Kong, China. Almost 400,000 people took part in it. They answered questions about their lifestyle, food, and what raw (生的) and cooked vegetables they ate. The study actually found that the risk of dying from heart problems was around 15% lower for those eating the most vegetables, especially raw vegetables.
However, scientists explained that many other factors (因素) also have something to do with this 15% drop. These factors may affect (影响) our health just as much as vegetables. These include other things we eat, how much exercise we get, where we live and whether we smoke or drink. Lead researcher Dr. Qi Feng from the University of Oxford said, “Our large study did not find clear evidence (证据) that how many vegetables you take can cut down chances of heart problems.”
But does it mean that eating vegetables is futile? No. Many other scientists advise that people should still eat at least five kinds of fruit and vegetables every day. That’s because vegetables are important for keeping good health and reducing (减少) the risk of serious illnesses.

4 . In school, we are told to drink water between classes. Our parents ask us to bring our water bottles to school and we’re reminded by experts that water is good for our skin and helps control our weight. But how much should we actually be drinking?
For many years, people have followed the advice of drinking eight glasses of water, eight times a day, known as the“8×8 rule”. According to Jessica Brown, this seems to have partly come from a misunderstanding of old advice that was published almost 80 years ago. In 1945, a study advised drinking one millilitre (毫升) of liquid for each calorie (卡路里) of food. This is about two litres of water a day, or eight glasses per person. But, Jessica says, the reality is that different people have different needs. Weight, age and activity level all play a role in how much water someone should drink.
Then do we need to control how much water we drink? It’s not that important, according to Dr. Stanley Goldfarb from the University of Pennsylvania. He says our bodies are good at telling us when we need water. When we are thirsty, it means our bodies need more water. Our kidneys (肾脏) help us keep the water we have, even before we feel thirsty.
There are, of course, benefits to drinking water. It helps our bodies stay at the right temperature. It helps us keep away bad things in our bodies. It helps us digest (消化) food. It protects our joints (关节).
So, next time you feel thirsty, reach for a glass of water. But don’t worry if you don’t drink exactly eight glasses a day. Your body knows what it needs.

10 . Do you get in trouble for feeding your dog on food from dinner under the table? A new study suggests that by sharing “people food”, you might actually be helping to keep your pet healthy.
Many dogs are fed dry processed food. Science has shown that a diet (饮食) of processed food is not health y for humans. Scientists from the University of Helsinki, in Finland, say this diet is not good for our pet dogs, either.
The scientists discovered that the foods a dog might find in an owner’s meal such as eggs, fish, meat and vegetables may be better than a diet of just dog food. This is because having different kinds of foods leads to more variety (多样性) in microbes (微生物), which are little living things, too small to be seen with our eyes. There are millions of them in human and animal bodies. Some are bad for us, but many are good for us, and they play important roles in helping us digest (消化) food.
A total of 8,500 young pet dogs took part in the study. 4,500 of them were under 6 months old, and the rest were between 6 and 18 months old. The owners were asked about what foods they had fed their pets and how often. When the dogs reached adulthood, their owners reported that about 20% of the dogs showed CE symptoms (症状) such as weight loss. However, if dogs had been fed a mixed diet while young, it was 22% less possible for them to experience CE symptoms later in life.
Dr. Anna Hielm-Bjorkman told The Times of London, “Dog foods on sale are described as providing a complete diet... But what we show is that variety is important. Nobody would give 12 years of the same food to a child, then why should a dog be different?”
