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 food. She cuts off the moldy pan and eats the rest. Is it safe to do this?

Mold(霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or gray.

Mold makes food ®oft and changes it's color. Moldy food tastes quite bad—and it's not safe to eat.

If you find mold in soft food, just throw it away. Bread, tomatoes and hot dogs are soft food. This kind of food allows mold to easily grow below its surface.

But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold and 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, peniciliium(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:

It's getting hotter and hotter outside. Summer is already here! Summer means high temperature, more outdoor activities and all kinds of fruit and vegetables. How can we stay fit in this exciting season? Here are some good ideas:

Eat and drink properly

What is healthy to eat in summer? Fresh and light food. Fish can be a good choice. It can keep your body energetic and help fight against the burning sun. Colourful fruit and vegetables is another good choice. They not only please your eyes, but are full of healthy chemicals(化学物质). Tomatoes can help protect your skin against sunburn. Blueberries are good for your brain and eyes. The more colour, the better!

With all those summertime activities you will be thirsty. What to drink? Water. Water has zero calories(卡路里) and is the perfect drink to stop your thirst. Try not to drink too many energy drinks, sports drinks and soda drinks which have lots of sugar and caffeine(咖啡因) in them.
