Animal study: Fat in childhood? Weak muscles for life, says animal study
Doctors are concerned about the growing numbers of men and women that will need medical care during old age. We are all living longer, and as a result Alzheimer's, sarcopenia, diabetes and osteoporosis are taking on epidemic proportions. Researchers at the Joslin Diabetes Center in the US published an animal study which suggests that the numbers of elderly people with weak muscles are likely to grow more than we had expected.
Study
Results
The researchers damaged muscle tissue in their lab animals by exposing it to extremely low temperatures. They then examined the tissues three days later to see how well they had recovered. In the mice whose mothers had had enough to eat, overfeeding reduced the recovery ability by 42 percent. The recovery ability of the offspring of underfed mothers was 64 percent less.
Conclusion
It is clear that they are referring to the increasing numbers of children who are too fat. It seems likely that these children in older age may lose muscle mass and strength more quickly, and will therefore need more help.
In many developing countries overweight is also on the increase. In these countries underfeeding and overfeeding go hand in hand – and for these countries the relationships that the Americans have uncovered are even more worrying.
