Pregnant women who drink fluoride-treated water may have children with lower IQs - but only if they give birth to boys
Pregnant women who drink fluoride-treated water may give birth to children with lower IQs, a new study suggests. Surprisingly, boys seemed to have much lower scores when their mother's had high fluoride levels than girls did.
Researchers from York University in Toronto, Canada, found that the more fluoride that was present in a mother's urine, the lower her child's IQ score was.
According to Centers for Disease Control and Prevention, water fluoridation can reduce the amount of decay in children's teeth by up to 60%.
However, experts say fluoride can be dangerous in high concentrations. It can cause dental fluorosis, which is when faint white streaks appear on the teeth when younger children consume too much fluoride. Excess levels of the chemical can also cause skeletal fluorosis.
It is the fashionable superfood recommended by wellness gurus as a perfect way to start the day when it’s sprinkled on porridge.
But scientists are warning that eating too much flaxseed could cause cyanide poisoning.
Also known as linseed, it is rich in fibre, omega-3 fatty acids and micronutrients, and in the current trend is added to breakfast cereal or blended into smoothies.
But the seeds also contain a naturally occurring compound called amygdalin, a type of ‘cyanogenic glycoside’ that can produce cyanide gas as it degrades.
