JOHANNESBURG (AP) — U.S. President Barack Obama exhorted the world Tuesday to embrace Nelson Mandela's universal message of peace and justice, electrifying tens of thousands of rain-lashed spectators and prompting a standing ovation by scores of heads of state in a South African stadium.
A father's diet influences the health of his offspring, according to a study published on Tuesday that suggests men, like women, should plan to eat and live healthily in the run-up to conception. Researchers led by Sarah Kimmins at McGill University in Montreal, Canada, looked at what happened when male lab mice had a diet that was poor in vitamin B9. B9, also called folate, is present in green leafy vegetables, cereals, fruit and meat. Women often take folic acid supplements, before and during pregnancy, to reduce the risk of miscarriage and birth defects in their offspring.
