DHA and Healthy Babies
July
20,
2004
Researchers have found that babies born to mothers with higher
blood levels of the omega-3 fatty acid DHA at delivery had advanced
levels of attention spans that existed well into their second year
of life. During the first six months of life, these infants were two
months ahead of babies whose mothers were low in DHA. Attention is
an important component of intelligence early in life. DHA is
important for the developing brain which accumulates large quantities
of DHA during the first two years of life. The brain and nervous
system contain very large concentrations of DHA compared to the rest
of the body, and it is also needed for development of the retina in
the eye. The study is published in the August issue of the journal
Child Development.

DHA is found in fish, plankton, and in supplements. Studies show
that babies raised with sufficient levels of DHA have an edge in
terms of early cognitive development, this is the first study that
I know of where it benefits the baby's cognitive development in
the womb, even though this is the logical conclusion since DHA is
needed for brain development. Women who are low in DHA have a
higher risk of developing post partum depression, and studies show
that DHA can decrease the risk of developing and may even treat
this type of depression. Unfortunately, the fish supply is tainted
with mercury, PCBs and other contaminants. We have posted a guide
to healthy fish selection; see our Radio Studies for June 25th.
Exercise Helps the Elderly Live Longer
Both men and women aged 65 or older who exercise once a week,
were 40% less likely to die over a 12 year period than their peers
who are physically inactive. Researchers at the Karolinska Institute
in Stockholm, Sweden, interviewed 3,206 men and women aged 65 or
older in 1988-89. After a 12 year follow up the researchers found
that leisure-time physical activity even just for one hour each
week greatly cut the risk of all-cause mortality. These individuals
cycled, jogged or walked fast for an hour once a week. Even older
individuals who occasionally exercise, whether it was skiing,
hour-long walks, or other physical activity had a 28% drop in the
risk of dying over the 12 year period. Other contributors to an
earlier death besides getting no exercise were diabetes, currently
smoking, high blood pressure, obesity or being underweight. The
study appears in the July issue of the American Journal of
Preventive Medicine.

It obviously is very important to exercise. It is also very
important not to get hurt when exercising so you can continue to
exercise. You can minimize the risk of exercise injury by staying
hydrated, focusing on supplementing with antioxidant herbs before
exercising, and recovering rapidly from exercise. Antioxidant
polyphenols such as Grape Seed extract, the nutrient Creatine
Monohydrate, New Zealand Collagen, and protein will speed up
recovery while decreasing the risk of dehydration and injury.
If you recover quickly and fully from exercise, it is easy to
stay on a moderate exercise schedule.
Anxiety during Pregnancy and ADHD
A study followed 71 women and their first born children from
pregnancy through the age of 8 or 9. High levels of anxiety in
pregnancy were linked strongly to an increased risk of suffering
ADHD in the offspring. The study is published in Child
Development.
Traffic Pollution Shortens Your Life
In a study of people living within 150 feet of a major urban road,
or 300 feet from a major highway it was found that living near a
major road shortened your life by 2.5 years due to vehicular exhaust
exposure. In contrast COPD shortened the lifespan by 3.4 years,
chronic ischemic heart disease shortened it by 3.1 years and
diabetes shortened it by 4.4 years. The study included a population
of Canadians examined for pulmonary function from 1985 to 1999,
and followed through 2001. The study appears in the July 2004
issue of the American Journal of Epidemiology

There are herbs, foods, and nutrients that help protect you from
traffic exhaust. Ellagic acid, Sulforaphane, and other nutrients
help increase the level of detoxification enzymes that protect
delicate tissues, deactivate carcinogens and speed up the excretion
of these dangerous chemicals.
Can Cigarette Smoking Cause Diabetes?
39,528 nondiabetic men and 88,613 nondiabetic women aged 40 to 79
were followed from 1993 through 2002 in Japan. After ruling out
obesity, alcohol intake and other risk factors, smoking increased
the risk of developing diabetes by almost 30% in men and 40% in
women. The study appears in the July, 2004 issue of the American
Journal of Epidemiology. Commentary by Jerry Hickey, R.Ph. -
The same nutrients that protect you from vehicular exhaust help
protect you from cigarette smoke - Ellagic acid, and Sulforaphane,
and also NAC, Spirulina, Perna, Resveratrol, Green Tea EGCG, and
Astaxanthin.
