Many people believe eating healthily is expensive—and more costly than buying junk foods. But our new research, published in the BMC Pubic Health, shows this isn't the truth.

Most of the Australian family food budget(预算)is being spent on junk foods and drinks that are high in fat, sugar and salt.

Less than 7% of Australians eat healthily. The Australian adults get at least 35% of their energy from junk foods and drinks. As a result, two-thirds of adults (63%) and one-quarter of children are overweight.

We used the Australian Health Survey 2011—2013 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high and low-socioeconomic(社会经济地位低的)areas in Brisbane, and compared the diet prices with family incomes.

In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods(14%), and sugary drinks(4%).

In the low-socioeconomic area, a family of two adults and two children spend $640. 20 every two weeks on their present diets, but could buy a healthy diet for $560. 93 every two weeks. In the high-socioeconomic area, these numbers are $661. 92 and $580. 01.

Supermarket food prices were about 3% higher in the high-socioeconomic location. Takeaway foods were also relatively more expensive, but sugary drinks were priced similarly in both areas.

Present diets cost more than healthy diets, so it is surely not the price that helps to drive preferences for unhealthy choices.

When throwing away rubbish, do you know which dustbin it should go in? Have you ever noticed the differently-colored dustbins on the street?

Some of you might not be able to answer this question. However, it's actually quite important to know how to sort(分类)your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.

If you don't sort your rubbish, all of it will go to a landfill(垃圾清理场)and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

With this in mind, many cities in China have been running waste-sorting campaigns(活动)in recent years. for example, Shanghai announced in 2018 that within three years(2018—2020), all the people living in Shanghai should sort their rubbish into four groups: wet, recyclable, harmful and dry.

Wet waste is also known as household waste. They are things you don't want but that pigs can eat. Paper, metal, glass and other things that can be reused are recyclable waste.

Many other Chinese cities, including Shenzhen, are using this method to sort their rubbish. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their rubbish.
