How Bad Are Energy Drinks for Children?
What Are Energy Drinks?
There is no clear definition of what makes an energy drink, but it is usually taken that anything non alcoholic with more than 150mg of caffeine per litre is an energy drink. The first of its kind was Lucozade, which was launched in 1927. It was promoted as helping the sick to get better by regaining lost energy. Now there are lots of energy drinks on the market, all claiming to help boost energy levels and aid our performance.
What's in Energy Drinks?
We've mentioned the caffeine but energy drinks also contain water and sugar. Some also contain alts and amino acids.
What Are the Health Concerns?
The concerns focus on the two main ingredients (成分) of energy drinks, caffeine and sugar. Too much caffeine for children can in the short term cause headaches and raise blood pressure although it is important to mention that caffeine may not harm children in the long term. However, the short term issues do really worry teachers as caffeine can lead to an inability to sleep, which then affects a child's ability to focus and concentrate in class. In fact the maximum recommended (推荐) intake of caffeine for children is 2.5mg for every kilogram a child weighs, so if a child drinks energy drinks, it would be very easy to go over this dose.
Too much sugar can also cause health problems including obesity, tooth decay and in the long run Type 2 diabetes. So as with caffeine, if children are drinking energy drinks and consuming sugar in foods and other drinks, then it would be easy to go over the daily sugar allowance for a child. The thing to be aware of is what is called free sugars. Free sugars are those sugars which are added to foods or drinks, not the natural sugar found in fruits and vegetables. The amount of free sugar that a child should have is 19 grams per day for those aged 4-6 and 24 grams for those aged 7-10. So again it is easy to see that if children are drinking energy drinks over and above sugar that will be present in food they eat, it would be easy to go over the recommended amount of sugar each day.
Selling Energy Drinks to Children
There are currently voluntary bans for shops not to sell energy drinks to children under 16, but there are calls to make this illegal. Some schools have already banned children from bringing these drinks into school.
Age has its privileges in America, and one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age — in some cases as low as 55 — is automatically entitled to dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one's need but by the date on one's birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses — as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent(有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous (同义的). Perhaps that once was true, but today elderly Americans as a group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor. But most of them aren't.
It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between the generations.
Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involve a transfer of resources from the young to the old. Employment is another sore point. Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job — thereby lessening employment and promotion opportunities for younger workers.
Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don't need them.
It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can't take care of themselves and need special treatment; and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against — discrimination by age.
