There are only a few truly pleasant smells to wake up to in the morning. It might be the aroma of freshly baked bread, or the scent of your partner’s freshly brushed teeth - but for me, it’s the smell of freshly cooked coffee. Just a sniff of it makes me jump out of bed and rush to the kitchen for a gulp(大口) of the hot black liquid.

I also know the experience when I walk into a cafe for my double espresso(浓缩咖啡) or flat white, my mouth begins to water in advance. Although it’s really the caffeine hit I’m after, it’s the smell that makes me feel good.

However, this feeling sometimes turns to disappointment when I actually start drinking my hot coffee - the taste just doesn’t match the smell. This is particularly the case when I order a coffee to go in a tall paper cup and sip the liquid through a hole in the lid. Yes, it’s convenient, but is it really the right way to appreciate it?

Tim Hayward, a food writer and coffee shop owner，describes this process as “strange”. He says, “You walk into the coffee shop, you get the smell, but when you actually take the drink out, you are drinking it from something that is designed to deliver the hot liquid directly past your tongue, but stop any smell coming up to your nose.”

As well as removing the smell, takeaway coffee cups create a lot of waste and a vast majority of them still don’t get recycled. In 2011, it was estimated that 2.5 billion coffee cups were thrown away each year in the UK, and that figure is likely to be higher now. So maybe now is the time to really wake up and smell the coffee by drinking from a cup or mug in a cafe, chatting with friends and saving the planet!

Shake Shack is a new kind of restaurant becoming more popular in the U.S. The restaurants are not “fast food.” They are known as “fast casual”.

Observers say Americans want more choices and fresh food when choosing where and what to eat. This trend is one reason why the fast food restaurant McDonald's has struggled financially.

McDonald's is one of the best-known restaurants in the U.S. and even around the world. Their ads say “I’m loving it.” But in the last quarter of 2014, McDonald's net income dropped by about $300 million. Worldwide sales dropped for the eighth month and even more than expected.

Bonnie Riggs is a restaurant expert. She says one reason Americans like fast casual food is because it's new. They are creative, they are innovative, they are something different and we like to try new things.

Ms. Riggs says Americans made 61 billion visits to restaurants last year. Three out of four visits were to fast food restaurants, like McDonald's. Fast casual is still a small percentage of restaurant visits. She says it's “growing quickly” because they meet consumers' needs.

“They know it’s being prepared while they wait, it's fresh, uh, fresh ingredients, quality food, good tasting food at reasonable and affordable prices.”

Many Americans still like their fast food, Ms. Riggs says, they just are not going as often. And, she says, some people buy prepared foods at stores and take them home to eat. Others like to cook at home.

Around the world, eggs have been a breakfast staple（重要部分）for all good reasons. After all, an egg is a storehouse of vital nutrients, making it an essential part of a healthy diet. And for those of you who are afraid of having this power food because you're worried that it will add to your weight, remember, one egg contains about 80 calories and about five grams of fat. Hence, smart consumption is a far healthier option.

Eggs are a well-known rich source of protein — an important building block of bones, muscles, skin, and blood. The body uses protein to build and repair tissues as well as making other body chemicals. Unfortunately, unlike fat and carbohydrates(碳水化合物), the body does not store protein, and therefore has no reservoir to draw on when it needs a new supply. Thus eggs are the perfect sources and a smart food choice for those who reduce their intake of carbohydrates in a bit to lose extra weight.

Another important nutrient you'll find abundantly in egg white is riboflavin or Vitamin B2. And for all of you wondering what's the benefit of this nutrient, Riboflavin is a water-soluble(水溶性) vitamin which is involved in vital processes in the body and is necessary for normal cell function, growth, and energy production.

The yolk, which many of us avoid out of fear, is actually a very healthy food, if consumed in moderation(适度). Mainly fat, the yolk contains 1.33 gm of cholesterol（胆固醇） per 100 gms and is a rich source of vitamin A, B vitamins, calcium, phosphorous(磷) and iron. Incidentally, the iron found in the yolk is easily digested in the body. According to nutrition experts, one can eat one whole egg every day without harming one's cholesterol and other blood-fat levels. But for those who crave for more eggs, you can reduce fat by having one whole egg and the whites of the rest of the eggs.
