A
recent research study finds that what men eat really matters. A
report about a study of sperm health in young men which was published
on 15th August 2012 in the Biology of Reproduction journal's
papers-in-press section mentions that walnuts improves men's sperm
quality. I was really amazing to see this news. Isn't it really an
amazing study? I tried to find out more about this research through
Internet. And as I visited the BBC website I saw Dr Allan Pacey's view
interesting about this research in an interview given to BBC
regarding the research. "It
would be relatively easy to poke fun at studies like this, but there
is increasing evidence to show that aspects of a man's diet can
affect the number and quality of sperm produced by his testicles."
says Dr Allan Pacey of University of Sheffield who is the senior
lecturer in androgyny. The research led by Professor Wendie Robbins
from UCLA's Fielding School of Public Health tested the hypothesis
that 75 gm of whole-shelled walnuts day added to a Western-style diet
of healthy young men would beneficially affect semen quality. The
young men eating walnuts in the study conducted by Dr. Robbins
experienced improved blood lipid profiles. The study, which was
partially funded by the California Walnut Commission consumed a
western style diet used a randomized, parallel two-group, dietary
intervention trial with single-blind masking of outcome assessors,
was conducted with 117 healthy men, age 21-35 years. 58 participants
were asked to avoid eating tree nuts, and 59 were asked to eat 75 g
of walnuts a day. According to the Biology of Reproduction men who
ate the walnuts had increased levels of omega-3 and omega-6 fatty
acids while researchers found that the men who ate the walnuts
experienced improvement in sperm vitality, motility, and morphology.
At this study which looked the effect of walnut consumption on semen
quality in healthy young men, all
the participants gave blood and semen samples before and after
during the study period, which lasted for 12 weeks. At the end of the
12 weeks, neither group showed significant changes in any factor
which affects sperm quality such as body weight, body mass, or
physical activity levels. Someone might wonder why the researchers
have picked 75 gram. And here is the answer, it is because other
studies have suggested that this is enough to change lipid levels in
the blood. The researcher also showed fewer chromosome abnormalities
at the end of the 12 weeks than it did at the start of this study.
The study authors of this research emphasized that more research is
needed to see if eating walnuts actually works
to improve the male' sperm quality. The researcher concludes saying
that the findings demonstrated that walnuts added to a Western-style
diet improved sperm vitality, motility and morphology. Recently a
study published in the European
Journal of Clinical Nutrition
found
that walnuts significantly improve metabolic factors in overweight
individuals with type 2 diabetes too. Joe Vinson of the University of
Scranton in Pennsylvania believes that walnuts rank above peanuts,
almonds, pecans, pistachios and other nuts. Walnut nuts
are packed with many important B-complex groups of vitamins such as
riboflavin, niacin, thiamin, pantothenic acid, vitamin B-6, and
folates. So
isn't walnut a smart food choice?
