In recent years, studies of sperm quality in different populations from developing countries have shown a decrease that could have consequences for the survival of the human species. The decrease in sperm quality has been related to unhealthy lifestyles. Stress, the consumption of drugs, tobacco and alcohol and unhealthy diets seem to be the principal modifiable factors.
Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children -- and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called 'epigenetic inheritance' - patterns of chemical 'marks' on or around our DNA that are hypothesized to be passed down the generations. New research suggests this mechanism of non-genetic inheritance is likely to be very rare.
A father's exposure to nicotine may cause cognitive deficits in his children and even grandchildren, according to a study in mice. The effect, which was not caused by direct secondhand exposure, may be due to epigenetic changes in key genes in the father's sperm.
New research has shown that a lack of protein in a father's diet affects sperm quality which can have a direct impact on the long-term health of their offspring.
Scientists have gained a glimpse of how marks on our genes that could be linked to adverse health outcomes in later life behave differently in the first few days after conception, according to new research.
Preconception binge drinking may have negative consequences on future offspring's growth, social interactions and development during puberty according to a rat-based study published in the Journal of the Endocrine Society.
A child's health can be compromised not only by a mother who smokes or drinks during pregnancy, but by the obesity and poor diet of both parents well before the child is conceived, researchers say.
A child's growth and development is affected by the health and lifestyles of their parents before pregnancy -- even going back to adolescence -- according to a new paper.
A myriad of studies are showing biological fathers who drink alcohol may have a significant role in causing health problems in their children.
Whole grains form a part of many diets deemed to be beneficial for health - such as the Mediterranean diet. But what health benefits do whole grains offer in their own right? According to a new study, eating more of them may reduce mortality, particularly deaths resulting from cardiovascular disease.
The government classifies some additives as “Generally Recognized as Safe” or GRAS. They are presumed to be safe in food and are not required to undergo pre-market review and approval. This system makes sense for benign additives such as pepper and basil, but there are enormous loopholes that allow additives of questionable safety to be listed as GRAS. Manufacturers can decide whether these compounds are safe without any oversight by the Food and Drug Administration – and in some cases obtain GRAS status without telling the FDA at all.
Past studies have linked walnuts to reduced risk of breast cancer and improved sperm quality. Now, a new study claims that a diet enriched with the nuts could help prevent or slow Alzheimer's disease.
Chromosomes and genes contain the blueprint for your physical characteristics. But your parents' health and diet before you were conceived can also affect how your genes are expressed – and impact your long-term health.
In 1952, Sir Jack Drummond, a pioneering food scientist, was shot dead while on holiday in France. A local farmer was convicted of the killings. But was he really guilty - or was a more sinister plot at work, involving agribusiness?
