Male overnourishment may affect the intellectual development of future generations.

A nutritious diet is very important.
"too late" and excessive consumption of energy drinks or folic acid tablets may harm the health of future generations.
in animal experiments, German researchers have found that male mice that overeat certain nutritional supplements may have adverse effects on the intelligence of future generations.
not only the diet and living conditions of female mice before fertilization, but also the environmental factors faced by male mice can affect the development of offspring.
In the experiment, a team of researchers from the German Centre for Neurodegenerative Diseases grouped male mice and provided one group with a special diet, a diet rich in common ingredients in human nutritional supplements such as folic acid, methionine, amino acids, vitamin B12 and zinc;
six weeks, the researchers paired male and female mice and analyzed their offspring in detail.
results showed that the offspring of male mice fed a special diet performed worse in all learning and memory tests than the offspring of the comparison group (i.e., the general diet group), with the most severely affected being the spatial memory of the young mice.
the researchers explained that the nutrients in a particular diet are rich in methyl, a small chemical group that adheres to a gene if it is present in large quantities that can affect the activity of the gene.
diet, which contains large amounts of methyl, may have an effect on the DNA of the patriarchy and then pass it on to the next generation through sperm.
Eininger, who was involved in the study, said there was ample evidence that a diet that lacked methyl had adverse consequences, and new research suggested that excessive intake of methyl-containing diets also had adverse consequences.
he said it was still to be seen whether the conclusion would apply to humans.
study has been published in the new issue of the British journal Molecular Psychiatry.
