For many men diagnosed with testosterone deficiency, losing weight can help increase testosterone levels, say researchers, adding that, specifically a low-fat diet may be associated with a small but significant reduction in testosterone.

“We found that men who adhered to a fat restrictive diet had lower serum testosterone than men on a nonrestrictive diet,” said study researcher Jake Fantus from University of Chicago in the US.

“However, the clinical significance of small differences in serum T across diets is unclear,” Fantus added.

For the study, published in the Journal of Urology, the research team analysed data on more than 3,100 men from a nationwide health study (the National Health and Nutrition Examination Survey, or NHANES).

All participants had available data on diet and serum testosterone level.

Based on two-day diet history, 14.6 per cent of men met criteria for a low-fat diet, as defined by the American Heart Association (AHA).

Another 24.4 per cent of men followed a Mediterranean diet high in fruits, vegetables, and whole grains but low in animal protein and dairy products.

Only a few men met criteria for the AHA low-carbohydrate diet, so this group was excluded from the analysis.

The average serum testosterone level was 435.5 ng/dL (nanograms per deciliter).

According to the study, serum testosterone was lower in men on the two restrictive diets: average 411 ng/dL for those on a low-fat diet and 413 ng/dL for those on the Mediterranean diet.

The associations were adjusted for other factors that can affect testosterone, including age, body mass index, physical activity, and medical conditions.

After adjustment, the low-fat diet was significantly associated with reduced serum testosterone, although the Mediterranean diet was not.

Overall, 26.8 per cent of men had testosterone levels less than 300 ng/dL. Despite the difference in average testosterone levels, the proportion of men with low testosterone was similar across all diet groups.

The researchers noted that further studies will be needed to corroborate their findings, and to clarify the mechanism by which restrictive diets reduce testosterone.

But due to the difficulties of large-scale dietary studies, definitive trials are unlikely to be performed, they said.

“Therefore, our data represent a valuable approach towards answering this important question,” the researchers concluded. (IANS)

Higher Fruits and Vegetables Intake Beneficial for Women: Health Researchers

Higher fruits intake linked to fewer menopausal symptoms

A healthy diet, rich in fruits and vegetables is known to benefit the human body in so many ways, as now health and lifestyle researchers have found that it may also play a role in lessening various menopause symptoms.

Although hormone therapy has been proven to be an acceptable method for treatment of menopause-related symptoms for many women, the search for nonpharmacologic treatment options is ongoing, especially for women with certain risk factors and those who are not candidates for hormone therapy.

Specifically, there has been a focus on identifying modifiable lifestyle factors that might prevent or alleviate menopause symptoms, said the study, published in the Menopause: The Journal of the North American Menopause Society.

“This small cross-sectional study provides some preliminary evidence regarding the influence of fruit and vegetable intake on menopause symptoms,” said study researcher Stephanie Faubion from The North American Menopause Society (NAMS) in the US.

NAMS is North America’s leading nonprofit organisation dedicated to promoting the health and quality of life of all women during midlife and beyond through an understanding of menopause and healthy aging.

According to the researchers, previous studies have suggested that dietary factors may play a critical role in estrogen production, metabolism, and consequently, menopause symptoms.

In particular, the consumption of fruits or a Mediterranean-style diet, characterised by a high content of vegetables, fruits, cereals, and nuts, was linked to fewer menopause symptoms and complaints.

This new study goes a step further in looking at specific fruits and vegetables and their effects on various menopause symptoms.

Citrus fruits, for example, were called out as having an adverse effect on urogenital scores compared with other types of fruits, as were green leafy or dark yellow vegetables compared with other vegetables, they added.

“There is ample evidence that a healthy diet rich in fruits and vegetables has a beneficial effect on health in a myriad of ways, but additional study is needed to determine whether various menopause symptoms may be affected by dietary choices,” Faubion said. (IANS)
