A new report in the journal Human Reproduction showcases a study that links fatty, high-carbohydrate diets to lower sperm counts. A better diet that included high intakes of omega-3 fatty acids, found in fish and plant oils, were associated with higher sperm concentration, reports BBC News.

The team, led by Prof Jill Attaman from Harvard Medical School in Boston, questioned 99 men about their diet and analyzed sperm samples over the course of four years.

Compared with those eating the least fat, men with the highest fat intake had a 43 percent lower sperm count and 38 percent lower sperm concentration. Men consuming the most omega-3 fatty acids had sperm with a more normal structure than men with the lowest intake.

Prof. Attaman said, the magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease.

However, 71 percent of participants were overweight or obese, which could have had an impact on sperm quality. Furthermore, none of the men had sperm counts or concentrations below the normal levels defined by the World Health Organization of at least 39 million and 15 million per milliliter.

Commenting on the research, British fertility expert Dr. Allan Pacey, of the University of Sheffield, this is a relatively small study showing an association between dietary intake of saturated fats and semen quality.

Perhaps unsurprisingly there appeared to be a reasonable association between the two, with men who ate the highest levels of saturated fats having the lowest sperm counts and those eating the most omega-3 polyunsaturated fats having the highest.

Importantly, the study does not show that one causes the other and further work needs to be carried out to clarify this. But it does add weight to the argument that having a good healthy diet may benefit male fertility as well as being good general health advice.

Junk Food Diets Linked To Low Sperm Counts

Health researchers said on Thursday they had found a troubling link between higher consumption of rice and Type 2 diabetes, a disease that in some countries is becoming an epidemic.

Further work is need to probe the apparent association and diets that are notoriously high in sugar and fats should remain on the no-go list, they cautioned.

"What we've found is white rice is likely to increase the risk of Type 2 diabetes, especially at high consumption levels such as in Asian populations," Qi Sun of the Harvard School of Public Health told AFP.

"But at the same time people should pay close attention to the other things they eat.

"It's very important to address not just a single food but the whole pattern of consumption."

In the British Medical Journal (BMJ), Sun's team said the link emerged from an analysis of four previously published studies, carried out in China, Japan, Australia and the United States.

These studies followed 350,000 people over a timescale from four to 22 years. More than 13,000 people developed Type 2 diabetes.

In the studies carried out in China and Japan, those who ate most rice were 55 percent likelier to develop the disease than those who ate least. In the United States and Australia, where consumption of rice is far lower, the difference was 12 percent.

Participants in the two Asian countries ate three or four servings of rice a day on average, compared to just one or two servings a week in the Western countries.

White rice is the dominant form of rice eaten in the world. Machines produce its polished look by hulling and milling, leaving a grain that is predominantly starch.

The office may not be doing your figure any favors, I report in WSJs Work & Family column today and on WSJs Health Blog.

Some coworkers pressure dieters to eat forbidden foods. Others pass home-baked snacks desk-to-desk. Some tease colleagues about their diets, or even order them restaurant foods they arent supposed to eat.

Indeed, an ongoing poll of thousands of dieters on the weight-loss website SparkPeople cites co-workers as the second biggest source of negative pressure for dieters second only to spouses or partners.

Colleagues often mean well.Some see offering delicious food as a sign of friendship or affection, says Becky Hand, a registered dietician with SparkPeople. Many people dont understand how hard it is for others to lose weight. They might feel guilty that they arent eating a healthier diet themselves. Some might be afraid of losing a friend who changes her life by losing a lot of weight.

Whatever their motivations, co-workers can make life tough for dieters. Click here to read some of their stories.

Readers, do you work in a foodie office? Are colleagues constantly bringing in snacks, candies and pastries? Does your office tend to order in unhealthy food? How do you manage your own waistline amidst all the temptation? Or do you not worry about it in the slightest?

Work Isn’t Doing Your Figure Any Favors

NEW YORK (Reuters Health) - When it comes to managing children's obesity, cutting portion sizes and cutting carbohydrates can work equally well -- though carb control is tough for many kids, a new clinical trial finds.

Many adults have tried to win the battle of the bulge by shunning carbohydrates, especially highly refined or starchy carbs like white bread and potatoes.

But much less has been known about how those eating plans work for kids, including whether they are safe and nutritionally sound -- since low-carb diets tend to be relatively high in fat.

For the new study, researchers randomly assigned 100 obese 7- to 12-year-olds to one of three eating plans: one that followed the conventional wisdom of portion control; a low-carb diet; or a "reduced glycemic load" plan that cut down on certain carbs that typically cause surges in blood sugar -- like white bread, sweets and white potatoes.

Over one year, all three plans worked equally well in controlling kids' weight gain. The difference, researchers found, was that the low-carb plan was tough to stick with.

"All of these plans can work," said lead researcher Shelley Kirk, of the Heart Institute at Cincinnati Children's Hospital Medical Center.

"But the low-carbohydrate one was really challenging for kids to follow," Kirk told Reuters Health. The diet still helped control kids' weight, she said, because they followed it to an extent -- reducing carbs and calories, but not to the strict limits of the low-carb plan.

All of that, Kirk said, suggests that a modified version of low-carb could work well for at least some kids.

And the diet based on reduced glycemic load was essentially that: Certain carbs were "unrestricted" -- including fruit, vegetables low in starch and 100-percent whole grains. More limits were placed on starchy carbs, but they were still allowed.

Over one year, children in all three diet groups had similar improvements in their body mass index (BMI), a measure of weight in relation to height, after accounting for the fact that they were still growing.

A diet high in saturated fat has been linked with a reduced sperm count.

A study of 99 men attending a US fertility clinic found those eating junk food diets had poorer sperm quality.

High intakes of omega-3 fatty acids, found in fish and plant oils, were associated with higher sperm concentration.

More work is needed to confirm the findings, the researchers report in the journal Human Reproduction.

The team, led by Prof Jill Attaman from Harvard Medical School in Boston, questioned men about their diet and analysed sperm samples over the course of four years.

Compared with those eating the least fat, men with the highest fat intake had a 43% lower sperm count and 38% lower sperm concentration (number of sperm per unit volume of semen).

..it does add weight to the argument that having a good healthy diet may benefit male fertility as well as being good general health advice.

Men consuming the most omega-3 fatty acids had sperm with a more normal structure than men with the lowest intake.

Prof Attaman said: "The magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease."

Diet 'linked' to low sperm counts

(WTVR) Researchers have discovered that losing belly fat allows blood vessels to work better.

In a six month study, researchers at John Hopkins found that the more belly fat people lost, the better their arteries were able to expand when needed, allowing more blood to flow more freely.

Researchers studied 60 men and women who weighed an average of 215 pounds at the start of the program. Half of the participants went on a low-carb diet while the others followed a low-fat diet. All took part in moderate exerciseand their diets provided a similar amount of calories each day.

The findings of the study were consistent with early results presented at the annual meeting of the American College of Sports Medicine in Denver. That initial report was based on results after participants in the study had lost their first 10 pounds. These longer-term results show that weight loss, along with exercise, is important for improving vascular health, and suggests following a low-card diet rather than the conventionally recommended low-fat diet for weight lossis not a concern in terms of vascular health.

Doctors say being overweight increases the risk of cardio-vascular disease, especially if the fat is in the belly above the waist.

Losing belly fat helps improve blood vessel function

Eating junk food may reduce a man's sperm count, research has shown.

A study of men attending a US fertility clinic found those with the fattiest diets produced significantly less sperm. Their sperm density was also lower.

The research also showed that diets high in omega-3 fatty acids, found in fish and plant oils, were associated with improved sperm quality.

Men were divided into three groups according to how much fat they consumed. Compared with those eating the least fat, men with the highest fat intake had a 43% lower sperm count and 38% lower sperm concentration. Sperm concentration, or density, is defined as the number of sperm per unit volume of semen.

Men consuming the most omega-3 fatty acids had 1.9% more correctly formed sperm than men with the lowest intake.

Lead scientist Professor Jill Attaman, from Harvard Medical School in Boston, US, said: "The magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease."

The findings are reported in the journal Human Reproduction.

More work is needed to confirm the findings, say the researchers who acknowledge that their small study involving just 99 men was limited.

Eating a fatty diet did not appear to impair the fertility of any of the men in the study. None had sperm counts or concentrations below the "normal" levels of at least 39 million and 15 million per millilitre.

Leading British fertility expert Dr Allan Pacey, senior lecturer in andrology at the University of Sheffield, said: "This is a relatively small study showing an association between dietary intake of saturated fats and semen quality. Perhaps unsurprisingly there appeared to be a reasonable association between the two, with men who ate the highest levels of saturated fats having the lowest sperm counts and those eating the most omega-3 polyunsaturated fats having the highest."

Junk food diet 'lowers sperm count'

Fatty diets may be associated with reduced semen quality, according to a study published Wednesday in the European reproductive medicine journal Human Reproduction.

In a study of 99 U.S. men, researchers found an association between high total fat intake and lower total sperm count and concentration. It also found that men who ate more omega-3 fats (often found in fish and plant oils) had better formed sperm than men who ate less of these types of fats.

"At a global level, adopting these lifestyle modifications may improve general health, as high-saturated fat diets are known to be a risk factor for a range of cardiovascular diseases; but, in addition, our research suggests that it could be beneficial for reproductive health worldwide," said Dr. Jill Attaman, an Obstetrics, Gynecology and Reproductive Biology instructor at Harvard Medical School at the time of the research, in a statement.

"Little is known of how diet may influence male reproductive potential," researchers said in the study.

Men, with an average age of 37 years, who attended a fertility clinic were investigated between December 2006 and August 2010.

Researchers questioned them about their diet and analyzed samples of their semen. Also, 23 of the 99 men participating in the study were measured for levels of fatty acids in their sperm and seminal plasma.

Participants were divided into three groups according to the amount of unsaturated fats they consumed. Men with the third-highest fat intake had a 43 per cent lower sperm count and 38 per cent lower sperm concentration than men in the group with the lowest fat intake.

Men who consumed the most omega-3 fatty acids had slightly more sperm (1.9 per cent) that were "correctly formed" than men in the third that had the lowest intake of omega-3.

Meanwhile, researchers noted some limitations: the study size is small and needs to be replicated by further research to confirm the role of fatty diets on men's fertility, they said. Also, the use of a food frequency questionnaire might not accurately reflect men's actual diets. And only one semen sample per man was collected.

Researchers cautioned that the study can only show an association between dietary fats and semen quality and cannot show causation.
