Cutting back the calories may do more than whittle your waistline, it could protect your brain from the effects of aging. A new study suggests that calorie restriction can help slow the normal process of cell death that happens with age.
カロリー制限はボケの進行を遅らせる？？
Researchers say the body naturally goes through a process known as apoptosis, or cell death, to destroy old cells so new ones can be made, and many factors can alter this process. Age-related diseases, such as Alzheimer's and Parkinson's, cause a higher-than-normal loss of cells in the brain, which can lead to loss of function.
Previous studies have suggested that calorie restriction can boost life span and mental capacity. That prompted researchers in this study to look at whether cutting calories might also play a role in protecting aging brain cells.
The study authors compared levels of proteins indicating brain cell death in two groups of rats. One group was given unrestricted access to food and water throughout their lives. The other was given 40% fewer calories (but still adequate nourishment) than the unrestricted group.
Researchers found that the levels of these proteins increased with normal aging in the rats fed unrestricted diets. The rats given a restricted diet did not have an increase in the levels of these proteins.
Another protein thought to protect from cell death dropped by 60% in the well-fed rats, but it actually increased over time in the calorie-restricted rats.
Finally, DNA fragmentation, a third indicator of cell death, more than doubled in the unrestricted rats with age, but this increase was 36% less in the calorie-restricted rats.
The complete results appear in the Jan. 2 online edition of the Journal of the Federation of American Societies for Experimental Biology.
Although the results are promising, researchers say more study is needed to completely understand the processes that lead to cell death and the role nutrition plays in that process.
Meanwhile, they say, this study provides yet another reason to watch what you eat.
"We're not going to do it right away to improve our memories; we're going to do it probably in general for the first reasons, which would be to prevent cardiovascular disease and cancer," says study author Christiaan Leeuwenburgh, director of the Biochemistry of Aging Laboratory at the University of Florida, in a news release. "And maybe it also has a protective effect -- and it's very suggestive in this study that it does -- on brain function."
Workouts at home 家でのトレーニング
Those who cannot find time to be fit, will soon find time to be ill, goes the saying. Twenty minutes each day is all that fitness experts ask of a normal healthy individual for fitness activity. Incorporate this with a normal workday schedule. Exercise while watching TV, hearing the news or music or waiting for the cooker to whistle. Make it something you do with the children.

Exercises that can be done at home
Cardiovascular心臓血管の？？心臓の血の巡りが良くなる？？
Skipping
On the spot jogging
Stair climbing
Strength Training
See Strength Building. These exercises can be done at home.
You can also exercise with weights. The simplest will be to fill two half-litre water bottles and hold each in a hand and try each of the following in two sets of 10 –12 repetitions :
Raising arms overhead and back to position
Arms raised in front, to shoulder level, and back to position
Arms raised to the side, to shoulder level and back.
Arm curl
Tri-extension.
Flies (raising arms sidewise overhead in one count, as if flying, and back to position.)
Stretching
All exercises under heading Stretching Activities can be done at home.
柔軟体操は家庭でできる。
