Saturated fats, which are found in cheeses and meats, are being blamed for falling sperm counts among Danish men in a new study. More from Reuters:
Researchers, whose report appeared in The American Journal of Clinical Nutrition, found that young Danish men who ate the most saturated fats had a 38 percent lower concentration of sperm, and 41 percent lower sperm counts in their semen, than those who ate the least fat.
“We cannot say that it has a causal effect, but I think other studies have shown that saturated fat intake has shown a connection to other problems and now also for sperm count,” said Tina Jensen, the study’s lead author from Rigshospitalet in Copenhagen, the Danish capital.
The research is not the first to connect diet and other lifestyle factors to sperm production and quality. In 2011, Brazilian researchers found that men who ate more fruit and grains suchs wheat, oats or barley had faster and more agile sperm, as well as more sperm overall.
But that study and most others looked at these associations using data on men seeking fertility treatments, which may not be representative of all men.

A new study published in the Journal of the Academy of Nutrition and Dietetics has found that parents eat more foods containing saturated fats than people without children. By making better food choices, researchers concluded, parents can not only prevent weight gain and health problems for themselves, but they can be better role models for their children. CNN.com reports:
A diet high in saturated fat can lead to obesity, high cholesterol, heart attacks and Type 2 diabetes.
“Parents of younger children do tend to bring in more convenience foods into the home more often,” said Dr. Helena Laroche, the lead author on the study. “That may account for the difference in saturated fat intake.”
Laroche’s study appeared in the Journal of the Academy of Nutrition and Dietetics. It examined data collected in the Coronary Artery Risk Development in Young Adults cohort study, which followed more than 2,000 young adults for 20 years.
Her research focused on the first seven years of a new parent’s life, comparing how often they ate and what they ate to the eating habits of people without children.
It asked people to document how much saturated fat was in their diet, how many fruits and vegetables they ate, how often they went out for fast food, and how much soda and juice they consumed.
Other than with saturated fat intake, parents’ diets were similar to those people without kids. “Ultimately, neither had the ideal diet at the end of seven years,” Laroche said.
Still, Laroche said, parents should know that what they choose to eat sends powerful messages to their children.
“The big takeaway from our study is that we really do want parents to be better role models for their children when it comes to healthy eating,” she said.
