Our body needs a small amount of sodium to work properly, but too much
sodium is bad for our health. Excess sodium can increase our blood pressure and your risk
for a heart disease
and stroke.
Researchers from the University
of Wyoming in the U.S did a new
study that claims that intake of excessive salt can
This study was presented at the European Congress of
Endocrinology in Dublin. As the salt content of Western diets continues to
increase these findings could have significant consequences for the
reproductive health of future generations.
Researchers from University of Wyoming, USA led by Ms Dori
Pitynski are investigating the effect of varying levels of dietary salt on the
onset of puberty in rats. They found that rats fed a high salt diet (equivalent
to 3 or 4 times the recommended daily allowance for humans) had a significant
delay in reaching puberty compared to those fed a normal (low) salt diet.
Interestingly, rats that had salt completely excluded from their diet also had
delayed puberty.
Ms Pitynski and colleagues concluded that salt intake is necessary for onset of puberty but that excesses can affect reproductive health. Late onset of puberty can lead to behavioural problems, stress and reduced fertility. Late onset of puberty can lead to behavioural problems, stress and reduced fertility
There have been a lot of studies that have shown the effects of dietary
fats on puberty at various levels, but no one has previously looked at the
effects of salt in terms of puberty and reproductive health. Ms. Pitynski said
that Our work shows that
high levels of fat and salt have
opposite effects on
reproductive health.” The high fat diets ended up accelerating the onset of
puberty, but when rats are fed the excessive salt diets even with the high fat
diet combined, there was still a delay in the onset of puberty. This study for
the first time showing that salt content in diets are more important and
valuable in terms of puberty and reproductive health than fat content in diets.
According to recent guidelines issued by the
World Health Organization revealed that people consume far more sodium in the
form of salt than the actual requirement of 5 grams a day for adults. Sodium is
found in much higher amounts in processed foods, such as bacon, bread and
processed meat as well as in condiments such as soy sauce and stock cubes; which are
becoming more prevalent in the Western diet. “Current salt-loading in Western
populations has the potential to drastically affect reproductive health, and
warrants further attention” said Ms Pitynski.
What is processed food? The Dietary Guidelines
for Americans define the term "processed food" includes "any raw
agricultural commodity [product] that has been subject to processing, such as
canning, cooking, freezing, dehydration, or milling."1 Processing certain foods can make them last
longer by killing organisms in the food or slowing their growth.
Ms. Pitynski said that more research is needed and more people need to
be paying attention to the amount of salt that they are consuming on a daily
basis. It is even more important for parents to control how much salt their
children are getting on a daily basis, since the delay of puberty in their
child can have significant negative impacts later in life in terms of having
children.
Sodium Reduction Is actually Challenging
Types of food matter: More than 40% of the sodium we eat each day comes
from just 10 types of food ranging from the number 1 source—breads and rolls—to
snack foods, which are 10th on the list.
Sources of food matter: About 65% of sodium comes from food bought at
retail stores, where you can look for lower sodium choices. About 25% comes
from foods made in restaurants, where it can be difficult to see how much
sodium is in your meal.
Brands of food matter: Different brands of the same foods may have
different sodium levels. For example, sodium in chicken noodle soup can vary by
as much as 840 mg per serving.
Recent guidelines
from WHO state that populations around the world are consuming much more salt
than is physiologically necessary.
But with this
study it is now clear how a mismanaged dose of sodium ruin your health. so from
today itself keep a check on your as well as your childs, intake of salts.
