Food companies engineer junk food to make it addictive. They label their products to make them seem much healthier than they are. Their advertisements target children. All of this is according to a news report read recently by students in a Texas middle school. They were taking part in an experiment run by the University of Chicago and the University of Texas. “I don't understand how this is even legal, ” said a girl who took part in the study.

Researchers had students learn about food-industry advertising strategies. They wanted to know if learning about them would change how kids feel about junk food. All over the world, kids are eating more foods that are high in salt, sugar, and fat. That is partly the result of clever ads that make junk food irresistible. Christopher J. Bryan led the study. He says that when kids question the motives behind junk food ads, they feel like they're fighting injustice. The reward is knowing they are doing the right thing.

Junk food has been linked to health problems such as heart disease, obesity, and diabetes，But in 2018，food companies spent nearly $9 billion TV ads selling unhealthy fare. Companies use varying strategies. An ad with cartoon characters may make chips seen fun to eat. A professional athlete enjoying a sugary drink may make it look cool. Advertisers                           know that if kids want a product, they'll annoy their parents to buy it. Even parents don't notice the power of ads. By the time they are adults they have been used to junk-food advertising. They just don't see it.

In the Texas study, Bryan had students view ads on iPad. Their job was to write or draw on the screen, to make each ad's message true. For example, a McDonald's ad showed a Big Mac (巨无霸) and the words “The thing you want when you order salad. ” To the end of the sentence, a student added “should be salad”.

Three months after analyzing ads, students were still choosing healthier snacks: milk instead of sugary juices, fruit over cookies. Kids are becoming conscious of themselves as agents in the world. They see a chance to make the world a better place.

Half a year ago I came across a book called “Salt, Sugar and Fat. How the Food Giants Hooked US”, but finished it only recently. I am far from being a fan of junk food, over-salty, or over-sweet stuff, and honestly this food doesn’t appeal to me at all. Maybe it is related to the fact that I grew up in Russia and at that time we were not so exposed to the foreign, especially made in America foods. We knew Coca Cola, Pepsi, juice powder and Cheetos, but this stuff was not so cheap or available to buy it every day and we couldn’t buy them in large quantities. We didn’t know the word “fat” was not a bad thing but a normal of life for some people. We always had sweets and especially on holidays they were served as a dessert along with a cake. Russians like eating sweets when they drink tea. Even with my passion to desserts I still can’t relate myself to the people Michale Moss was writing about, those consumers who could not say “no” when it came to junk food.

What I found interesting in the book was that the author didn’t focus on diets, necessity to exercise, sleep well at night and all other things we all are pretty aware of. The aim was not to teach people how to live but instead, after having made a huge research, interviewed more than 100 people in the food industry, Moss reveals the ugly of the food business. It puts all the facts in front of us and offers a choice: to buy or not to buy. However, the answer was known at the very beginning. Moss mentions the well-known food like Coca, Cola, Pepsi, Nestle and some others and tells how skillfully the consumers can be cheated when it comes to choosing what to put in the food basket in the supermarket. We like this taste of a chocolate, the crispy chips, and sweet porridges because it was all put on test by groups of scientists who made experiments to reveal what kind of taste will be most appealing to us. It involves brain, of course. Apart from scientific researches, it was also due to successful marketing strategies and plans that people prefer to buy food.

In this companies’ money race, the most vulnerable(易受伤害的)victims are kids. They can’t tell good from bad and love everything that makes them feel good. Commercial ads of fast food particularly targeted kids and played on the fact that mothers can’t fully control what their children eat because they spent all day at work. Mothers themselves buy chocolates bars and com flakes for their kids, guided by a powerful brainwashing that actually, these products were not unhealthy, on the contrary, it was encouraged to give them to kids, because fat and sugar provide energy, so they are good, right?

Giving a credit to some food companies, they made attempts to fight the trend, but consumers, who already worked a habit of eating too salty, too fatting and too sweet products, didn’t react to the changes. So the companies returned to the old policy. Surprisingly, such behavior was strongly backed up by the government.

I would definitely recommend reading this book not only to those who struggle in the battle with his addiction to fast food but also people living healthily. It casts light on many things, including how vulnerable we can be in front of corporations and their powerful and accurate marketing strategies.

CHICAGO -- New research on vegetables and aging gives mothers another reason to say "I told you so." It is found that eating vegetables appears to help keep the brain young and may slow the mental decline（下降） sometimes associated with growing old.

On measures of mental sharpness, older people who ate more than two servings of vegetables daily appeared about five years younger at the end of the six-year study than those who ate few or no vegetables.

The research in almost 2,000 Chicago-area men and women doesn't prove that vegetables reduce mental decline, but it adds to mounting evidence pointing in that direction. The findings also echo（回应） previous research in women only.

Green leafy vegetables including spinach（菠菜）, kale and collards （甘蓝） appeared to be the most beneficial. The researchers said that may be because they contain healthy amounts of vitamin E, an antioxidant（抗氧化剂） that is believed to help fight chemicals produced by the body that can damage cells.

Vegetables generally contain more vitamin E than fruits, which were not linked with slowed mental decline in the study. Vegetables also are often eaten with healthy fats such as salad oils, which help the body absorb vitamin E and other antioxidants, said lead author Martha Clare Morris, a researcher at the Rush Institute for Healthy Aging at Chicago's Rush University Medical Center.

The fats from healthy oils can help keep cholesterol（胆固醇）low and arteries （动脉）clear, which both contribute to brain health. The study was published in this week's issue of the journal Neurology and funded with grants from the National Institute on Aging.
