Here are five cooking habits that could be costing you important nutrients, causing you to overeat——or even making you sick.
A 2015 review showed that boiling vegetables resulted in a high loss of vitamin C ． 1 ． "If you're not drinking a soup, you're missing out on nutrients," says Nishta Saxena, a dietitian based in Toronto .
While your favourite old cookbooks likely tell you to wash a chicken before cooking, this outdated advice is a safety risk. Cleaning meat in water may remove some of the bacteria, but it's also likely to pass it around your kitchen. 2 ． And clean your hands after you've finished the cooking.
Removing skins from fruits and vegetables
"Large amounts of nutrients are found in the skins." says Liz Powell, who is a dietitian from Vancouver. " Concern about chemical remains isn't a good enough reason to do the removing. 3 ． "
A smoothie (a mixed drink) is a smart way to eat some greens. 4 ． They're often short of protein and healthy fat. These things work together to keep us feeling full and satisfied. Without them, it's not really a balanced meal, Powell suggests adding some foods which contain protein or having a piece of wholewheat( 全麦的 )bread on the side.
We think we can add anything to salads, and they'll still be a nutritious choice. But it's just not true. If you're topping your bowl with dried strawberries and sweet cheese, you've easily added 30 grams of sugar to your so-called healthy lunch. 5 ．
A ． You should choose healthy produce for your family.
B ． But these kinds of drinks are likely to be unbalanced.
C ． To stay safe, don't wash the meat when preparing it.
D ． Cabbage. for example, loses about 33 % of its vitamin C ．
E.Nuts are better choices to improve the taste of your greens.
F.The skins of potatoes contain more nutrients than its inside part.
G.Washing your produce will remove some chemicals from the surface.
It is always said that China is the homeland of tea, which has a very long history of tea. 1 ． However, unlike the western custom of using a convenient teabag, Chinese go to a lot of effort and time to prepare good tea for their guests, using tea leaves, natural spring water and a special kettle etc. to create worldwide famous tea culture. Tea is not just a drinkable beverage( 饮料 ), but also a taste of Chinese traditional culture and inheritance( 继承 ) of spirit. Unsurprisingly, there are various tea leaves in China. 2 ．
3 ． Good green tea leaves have jade green with fresh vitality. Twisted pan green tea shows glossy gray green. If some of the tea leaves have dry, dark and brown colors, it means it is old tea. If the leaves have mixed, large contrast colors, it is believed that the tea is mixed with yellow leaves, old leaves and even old tea, which does not live up to the standard of good tea.
➢Flavor( 味道 )
New tea is extremely clear and transparent with strong aroma( 芳香 ), while old tea is characterized by brown color and weak fragrance. Take green tea and black tea for example, new green tea tastes a little bitter first, and then the fresh sweet taste begins to surface gradually, leaving a long and memorable after taste in mouth. 4 ．
➢Place of origin
There is great gap of quality among various places of origin. 5 ． For example, it is well-known that Yunnan produces the best quality Pu'er tea and premium Oolong tea can be found within Fujian Province.
A ． Every tea leaf has its own shape.
B ． Some varieties are identified by tightness of the leaves.
C ． It is always advised to select tea from its main producing areas.
D ． While you’re selecting tea, you should pay attention to following aspects.
E.For foreigners in China, drinking tea may seem like simple refreshment( 提神 ).
F.Generally, new tea leaves look fresh and pleasing, with light green or dark green.
G.On the contrary, if bitter taste takes the lead and fresh sweet taste subsides( 减弱 ), it is black tea.

Six weeks before his birthday, Giuseppe Paternò achieved the dream of a lifetime: He got a university degree.
Mr. Paternò's graduation has inspired news coverage around the world, partly because of his age. But he has mainly drawn attention because his life story speaks of commitment, a theme that has encouraged as millions of schoolchildren in Italy and elsewhere faces extraordinary uncertainty during the coronavirus pandemic.
Born in Palermo in 1923, the first of seven children in a “very poor family,” Mr. Paternò began working soon after finishing elementary school. “The family was large, there was only one paycheck, we were under fascism, and times were tough,” he said.
Eventually, he ended up at a publishing house where an enlightened boss persuaded his father to send him back to school for a three-year vocational degree. Mr. Paternò then worked for an insurance agency while he took private classes to become a telegraph operator. He used skills from the operator job when he was drafted into the navy in World War II. The job also opened doors to the State Railways Company, where he worked for more than four decades.
It was only after he retired, in the mid-1980s, that he returned to his books, taking theology courses through the Archdiocese of Palermo after a chance meeting with a philosophy professor who urged him to follow his love.
Mr. Paterno's son, Ninni Paternò, said that the family had not expected all the attention. “It's unbelievable!” the vounger Paternò said of his father. “He achieved his goal, but he didn't mean to be famous in newspapers around the world.”
University officials are hoping that Mr. Paternò will continue his studies on waster's course. But he isn't so sure. “I have to admit that in this moment, I don't know whether I would do it with the same spirit,” he said on Wednesday. Still, Mr. Paternò said he would probably continue anyway.

Sustainability( 可持续性 ), one of the biggest topics of the last decade, has become the ray of hope to protect the planet. It's a topic we can't ignore and we must act now in a more sustainable way.
What does that mean for the world of technology? E-waste is one of the planet's biggest contributing waste problems.
Not only e-waste, but the materials that go into tech products are part of the problem. Take the smartphone industry for example, dozens of metals, minerals which have to be taken from the earth(including 16 of 17 rare metals) go into making phones. And with demand for mobile phones bigger than ever, it's a problem that needs to be solved.
With a challenge comes an opportunity, and there's already some progress happening - great news for those of us wanting to be more sustainable with our tech. People used to turn their noses up at the idea of a second-hand product, but there's been a huge increase in demand for refurbished tech( 翻新技术 ). For example, refurbished smartphone sales in the US have risen by 28% in the last 12 months while brand new sales have fallen by 21%.
Many communities are making an effort to deal with e-waste as well. Cities, schools, or churches will sometimes hold events to collect e-waste and send it to recycling centers. Some companies even offer buy-back programs where people will be given cash if they turn in old devices.
So the next time you want to deal with your e-waste, whether a smartphone, a laptop, an MP4 player or other, consider the more environmentally-friendly choices. It is possible to be sustainable with your tech after all.
