folic acid late in pregnancy caused an increased risk of developing asthma

Folic acid supplements linked to asthma in newborns

Taking folic acid supplements before and during the first
trimester of pregnancy lowers the risk of neural tube defect
in the unborn.

Children born to women taking folic acid supplements late in
pregnancy are placed at an increased risk of developing
asthma, a new study finds.

Pregnant women are urged to take a supplemental dose of 400
micrograms of folic acid per day in the month preceding and
during their first trimester of pregnancy, in bid to reduce
the risk of neural tube birth defects in the unborn.

"Our study supports these guidelines, as we found no
increased risk of asthma if folic acid supplements were
taken in pre- or early pregnancy," said lead researcher
Michael Davies.

He, however, stressed that expectant moms should avoid high-
doses of the supplemental folic acid late in pregnancy.

According to the study published in the American Journal of
Epidemiology, taking supplemental folic acid in late
pregnancy increases the risk of asthma in the newborn.

Such adverse effects, however, are not reported when the use
of the supplements is confined to the early stages of the
pregnancy.

There is, moreover, no such link between the maternal
dietary folate levels and asthma in the newborn.

Folic acid ups prostate cancer rate?

Adopting a healthy diet rich in folic acid and other
vitamins can promote health and tackle cardiovascular and
neurological diseases.

While folic acid is believed to have anti-carcinogen
properties, a new study shows high doses of the compound
promote prostate cancer.

Taking adequate amounts of folate supplements can play a
critical role in the prevention of several cancers as well
as cardiovascular and neurological diseases.

According to the study published in the Journal of the
National Cancer Institute, folic acid supplements are not
beneficial with regard to prostate cancer, indicating that
men taking high doses of folic acid are two times more
likely to develop this cancer.

Aspirin however was reported to have no significant effect
on protecting men against prostate cancer.

Certain studies had similarly linked taking high doses of
folic acid supplements with colon cancer; high doses of
beta-carotene was also associated with a higher lung cancer
risk in heavy smokers.

Scientists concluded that nutritional supplements such as
folic acid, multivitamins, selenium, beta-carotene, and
vitamins E, C, D, B6 and B12 have no protective benefits
against cancer.

A government, of Israel, by Israel, and, for: Israel.
But all things that are reproved are made manifest by the light:
for whatsoever doth make manifest is light. The light shineth in darkness;
and the darkness comprehended it not. The light of the body is the eye:
if therefore thine eye be single, thy whole body shall be full of light.
But if thine eye be evil, thy whole body shall be full of darkness.
If therefore the light that is in thee be darkness, how great is that darkness!
Awake thou that sleepest, and arise from the dead,
and Christ shall give thee light. For my yoke is easy, and my burden is light.
