Does
caffeine have any effects on pregnant
women ?
| Caffeine
has long been suspect of causing mal-formations
in fetus, and that it may reduce fertility
rates. These reports have proved controversial. On men, it has been shown
that caffeine reduces rates of sperm mobility which may account for some
findings of reduced fertility. |
What
are the side-effects
of caffeine ?
| A
major study has found fewer suicides
among coffee drinkers than those who abstained from the hot black brew.
This is not a fluke finding because the study was very large, involved
a multiracial population, men, women, and examined closely numerous factors
related to mortality such as alcohol consumption and smoking. The unique
survey also found no link between coffee consumption and death risk. And
it confirmed a 'weak' connection of coffee or tea to heart attack risk
-- but not to other cardiovascular conditions such as stroke. |
What
are the effects of caffeine on your metabolism
?
| Caffeine
increases the level of circulating fatty acids. This has been shown to
increase the oxidation of these fuels, hence enhancing
fat oxidation. Caffeine has been used for
years by runners and endurance people to enhance fatty acid metabolism.
It's particularly effective in those who are not habitual users. |
