Scientists in London say they have found the best diet for both humans and the planet. If the world followed the so-called “planetary health” diet, the scientists told Reuters that each year more than 11 million early deaths could be prevented. Scientists say that the way we produce and eat food is very bad for the planet. For the health of the planet, they claim the same diet would reduce greenhouse gases and save more land, water and animals.
Tim Lang, a professor at Britain’s University of London, co-led the research. He told Reuters, “The food we eat and how we produce it determines the health of people and the planet, and we are currently getting this seriously wrong.” Lang added that the world’s population is expected to grow to 10 billion people by 2050. If we want to feed everyone, he explained, we all need to change what we eat and the way we eat by “improving food production and reducing food waste.”
Well, what do you eat on the planetary health diet? The scientists who created this diet say it is largely plant-based but still has small amounts of dairy, fish and meat. The diet calls for cutting red meat and sugar by 50 percent and doubling the amount of nuts, fruits, vegetables and legumes.
Food situations around the world are not equal. In certain areas, this would mean great changes. People in North America, for example, eat 6.5 times the recommended amount of red meat. On the other hand, people in South Asia eat only half the amount suggested by the new planetary health diet. Meeting the targets for vegetables would need big changes in other areas. In sub-Saharan Africa, people on average eat 7.5 times the suggested amount of vegetables like potatoes and cassava.
The scientists admit their goal will be difficult to achieve. But for them doing nothing is also not an option. Willet said, “If we can’t quite make it, it’s better to try and get as close as we can.”

【推荐1】Why is Eating Colourful Food Good for You?
Most of us are faced with the same choice numerous times a day: what to eat. Along with price, accessibility and preference, we’ll often use a food’s healthfulness to help us make a decision.
It’s widely accepted by researchers that we need a varied diet.
Eating lots of colours may lower your risk of missing out on all vital nutrients. “If we re missing a colour of the rainbow, we may be missing a function of that food,” says Minich. This is because plant foods contain thousands of natural compounds, which have anti-inflammatory (抗炎的) benefits.

Low-fat or nonfat dairy products
Poultry without skin
Lean cuts of meat
Whole grain bread and cereals
Fruit and vegetables

【推荐1】“When we are stressed, we are more likely to want to avoid not just the task at hand, but the negative emotions we feel around that task as well,” Alicia Wafaa neuroscientist and senior lecturer at Rensselaer Polytechnic Institute in New York, explains. “That’s because at a basic neuroscientific level, we have a bias toward the present and prefer the immediate reward of feeling good when the brain releases the neurochemical dopamine (多巴胺).”
Essentially, our brains are hardwired to approach tasks we find enjoyable and avoid those that produce negative feelings. “Our limbic brain (大脑边缘系统), the emotional part of our brain, is saying, ‘Let’s do this other thing and avoid that other stressful thing, while our prefrontal cortex (前额叶脑皮层) is the CEO of our brain, ” says Walf. “It’s making a plan, setting the goals, and making sure we stay on track. But there can be a disconnect when our limbic brain denies that prefrontal cortex message.” Then there’s the burst of energy we often get when we’re up against a deadline, which leads to a reward pathway within our brains and sets the foundation for procrastination (拖延症) as a habit. “When you sprint (冲刺) to the end and get to the goal, it’s so satisfying; we almost get ourselves in that pattern of ‘Well, I got it done, and it felt good,’” says Walf.
In an effort to retrain your brain, Walf recommends taking breaks to refocus your attention on the task at hand. Methods such as the Pomodoro Technique can help you stay focused, in which you work within 25-minute intervals followed by five-minute breaks and continue circling until the task of the day is completed. Integrating mindfulness techniques during those breaks, such as meditation (冥想), yoga, and journaling, can also help reduce the stress that causes procrastination. “Trying to minimize stress by deliberately refocusing on whatever the task is, versus those feelings of anxiety, is about retraining your approach to stress and behaviors,“ says Walf.
It can also help to “eat that frog”, or tackle the most difficult and most meaningful task of the day and do it first thing in the morning. If all else fails, try tricking your brain by giving yourself a small reward for working on the task you’ve been avoiding. “Little rewards really help us, especially when we’re trying to reach a large goal,” says Walf. “You have to recharge and keep yourself motivated. ”

【推荐2】Archaeologists used DNA taken from a broken clay pipe stem found in Maryland to build a picture of an enslaved woman who died around 200 years ago and had origins in modern-day Sierra Leone. One researcher called the work “a mind-blower.”
“In this particular context, and from that time period, I think it's a first,” team member Hannes Schroeder told The Washington Post. “To be able to get DNA from an object like a pipe stem is quite exciting. Also it is exciting for descendant(后裔) communities... Through this technology, they're able to make a connection not only to the site but potentially back to Africa.”
The pipe stem was found at the Belvoir plantation in Crownsville, Maryland, where enslaved people lived until 1864 and where a likely slave cemetery was recently found. DNA taken from the pipe linked back to a woman either directly from or descended from the Mende people, who lived in west Africa, in an area now part of Sierra.
Julie Schablitsky, the chief archaeologist with the Maryland state highway administration, told The Post the discovery, based on saliva(唾液) absorbed into the clay pipe, was a “mind-blower”. She also said records show the existence of a slave trade route Sierra Leone to Annapolis, plied(定期往来) by British and American ships. "As soon as people stepped on those slave ships in Africa," she said, “whether they were from Benin or whether they were from Sierra Leone, wherever they were from, that identity was lost. Their humanity is stripped from. Who they are as a people has gone.”
The new analysis is part of ongoing research around Belvoir that has given descendants of the people enslaved there new insight into the lives of their ancestors. Speaking to The Post, Nancy Daniels, a genealogist from Laurel, Maryland, who thinks she is a descendant of enslaved families from Belvoir but was not linked to the research on the pipe, called the discovery “overwhelming.” “I'm sitting here about ready to cry,” she said. “I'm sorry. I'm so happy ... Thank God for the DNA.”
This year, events and ceremonies are being held to mark the 400th anniversary of the arrival of the first enslaved people in America, at Jamestown, Virginia, in 1619. Slavery was effectively abandoned in the US on 1 January 1863, with the issue by Abraham Lincoln of the Emancipation Proclamation. It formally ended in December 1865, after the civil war, with the approval of the 13th amendment(修正案).

【推荐3】Look inward for better career advice
Sometimes we turn to others for advice on major career decisions.
Why does so much career advice end up being misguided?
What about going to people who are qualified to give advice?
At some point,you have probably noticed that you’re wiser when giving advice to others than you are in making decisions for yourself. You’re not alone. It often happens because we have more distance from other people’s problems than our own.
Advising others doesn’t just help us make better decisions, but it also leaves us more motivated to follow through.In one experiment, it was expected people were more motivated when receiving than giving advice.
If you want to get better career advice, you can start by reflecting on what you would tell someone else with a similar question. Listen to the advice you give to others. It’s usually the advice you need to take yourself.And it might be the best way to motivate yourself, too.
A.However,sometimes we make decisions depending on ourselves. |
B.But the opposite was true. |
C.But they may direct us in the wrong direction. |
D.It’s no guarantee that they will know what’s right for us. |
E.But it was easier said than done. |
F.The problem may start with who we approach for advice. |
G.The lesson here is that one of the most effective ways to get better advice is to give it. |
