Scientists in London say they've found the best diet （饮食） for both humans and the planet. If the world followed the "planetary （行星的） health" diet, the scientists said that each year more than 11 million early deaths could be prevented. For the health of the planet, they said the diet would save more land, water and animals.
This new food plan is the result of a three-year project. Tim Lang, a professor at Britain's University of London, said that the world's. population was expected to grow to 10. billion by 2050. If we want to feed everyone, we all need to change what we eat and the way we eat by improving food production and cutting down food waste. So, what do you eat on the "planetary health diet?
It mainly has to do with plants but it still has small amounts of dairy products （乳制品）, fish and meat. The diet calls for cutting red meat and sugar by 50 percent and doubling the. amount of fruit, vegetables and legumes （豆类）.
Food situations around the world are different. In certain areas, the diet would mean great changes. People in North America, for example, eat 6.5 times the recommended （推荐的） amount of red meat, while people in South Asia eat only half the amount suggested by the new "planetary health" diet.
Reaching that goal in vegetables would need big changes in other areas. In Sub-Saharan Africa, people eat 7.5 times the suggested amount of vegetables.
Walter Willett of Harvard University said that more than 800 million people around the world didn't get enough food while many more had very unhealthy diets. The scientists agree that their goal will be difficult to achieve. But for them, doing nothing is not a good choice. Willet said, "If we can't tally make it, it's better to try and get as close as we can."
