A Diet Without Enough Protein Can Cause Depression
Depression is a condition so common, the World Health Organization (WHO) calls it "a leading cause of disability."
Difficulty in falling asleep, loss of appetite, and loss of ability to concentrate are just a few of the other effects of depression. WHO estimates that worldwide, at any one time, 350 million people suffer from the condition. While life events such as the loss of a spouse or a job may create a happening of depression, many cases come from within and are not caused by a life event.
Now scientists are working on a new aspect of cure: nutrition. The Indian Journal of Psychiartry reports that both before and during a happening of depression, those with the condition will show a "poor appetite…" Many cases of depression, if not most cases, affect those who don't eat properly.
So what does protein have to do with all this? It all comes down to amino acids (氨基酸). Proteins are made up of amino acids, chemicals known as the "building blocks of life." There are 20 different amino acids.
Both the human brain and nervous system use amino acids as a substance that creates a signal from one brain cell to another or one nerve cell to another, thus relaying information between the cells. What the final result then?
Since amino acids make up protein, a diet which lacks in protein will cause weaker communication between the brain cells. This lessens the signal being sent from one brain cell to the next during a thought. This is why depression can often express itself as anger or aggression.
A. The ultimate effect is how we think.
B. Don't ruin your appetite by eating between meals.
C. Skipping meals itself can create a depressed mood.
D. A new research suggests that nutrition can lessen some of the risks of depression.
E. India is perhaps the world's leader in researching the connection between diet and depression.
F. Many of them are made by the human body, but nine others, the "essential" amino acids, must be eaten in one's diet.
G. The process can lead to twisted signals, which can not only lead to depression, but also, according to many scientists, aggression.
Lots of people stress out about talking in front of the class or getting laughed at if they make a mistake in front of an audience. {#blank#}1{#/blank#} The “stress hormones" that your body produces at times like these can actually help you focus.
But when worry and stress about performing get to be too much, these hormones give people that “red alert(紧急状态)” feeling—the one that causes you to feel cold or sweaty, or get butterflies in your stomach. {#blank#}2{#/blank#}
Be prepared. {#blank#}3{#/blank#} Rehearse(排练) as much as you can and practice in front of others at every opportunity. Most of all, think positively. Tell yourself “I'll be OK" or “I can do this" even if you are not 100% sure of it
Look after yourself. Before big performances it's easy to let taking care of yourself slip as you spend too much time on rehearsals and practice. {#blank#}4{#/blank#} Exercise can also help you feel good, and along with sleep and nutrition, is an excellent way of keeping those stress hormones from getting out of control.
Find out what the experts do. You can find books, DVDs, and online information about how to give your best when you perform, depending on what type of performance you're preparing for {#blank#}5{#/blank#} Or ask the cast of your school play or your drama or music teacher how they beat stage fright. And if your parents or grandparents ever performed, they may have their own secrets to share.
A. Confidence helps beat stress hormones. B. The following tips can help you avoid that feeling. C. You're less likely to freeze up if you're well prepared. D. You can do this whether you're performing alone or as part of a group. E. Check out stories about Olympic gymnasts or your favorite star to get their tips. F. Feeling nervous before a performance is part of your body's way of helping you do your best. G. You'll look and feel your best if you get enough sleep and eat healthy meals before your performance. |
