What's Driving the Decline in IQ Scores? Mercola June 2018
Mercola postulates that GLOBAL IQ decline is due to increases in
- Fluoride – seems unlikely since most countries do not use Fluoride
- Flame retardants s-eems unlikely since most countries do not use them
- Pesticides – seems unlikely since pesticide use has DECREASED in recent decades
- Chemical exposures to children
Vitamin D Life: Perhaps due to Reduced Vitamin D
- Poor cognition 26 percent more likely if low Vitamin D (29 studies) – meta-analysis July
- Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
- Parkinson's and Alzheimer's: associations with vitamin D receptor genes and race – meta-analysis July 2014
- Blacks with strokes having low Vitamin D were 3 times more likely to have cognitive impairment – Nov 2016
- Soldiers need vitamin D, but levels cut in half in 18 years – March 2014
- Cognitive decline with age – and lower Vitamin D
- Some people with lower vitamin D levels have lower IQ, mortality, etc.
- Obese, Blacks,
- Types of evidence that Vitamin D helps brain problems - 2014
Vitamin D Life: Perhaps due to Reduced Iodine
- Iodine levels have been decreasing and low Iodine is associated with less cognition
- Adding Iodine to salt added 11 percent to goiter states income (how much might vitamin D add) – July 2018
- Vitamin D and Iodine are similar, and both are deficient and important to health
Vitamin D Life: Perhaps due to Reduced Omega-3
- Infants getting 1 g of Omega-3 for 12 weeks got better brains – RCT March 2017
- ADHD, Autism, Early Psychosis and Omega-3 – review Dec 2017
- Adding Vitamin D, Omega-3, etc to children’s milk improved memory (yet again) – RCT June 2018
- Omega-3 found to treat Alzheimer’s and Parkinson’s in animals – Sept 2017
- Cognitive Impairment 1.8 times more likely if low Omega-3– Oct 2016
- Benefits of Omega-3 on brain development
- Preterm birth extended by 2 weeks with Omega-3 – Meta-analysis Nov 2015
- Cognitive decline in elderly slowed by Omega-3 – meta-analysis May 2015
- Omega-3 – fewer than 5 percent of adult women get the RDA – April 2018
- Far less Omega-3 and far more Omega-6 in recent decades
Vitamin D Life: Perhaps due to reductions in BOTH
- Adding Vitamin D, Omega-3, etc to children’s milk improved memory (yet again) – RCT June 2018
- Omega-3 and Vitamin D each treat many mental health problems - April 2018
- Vitamin D, Omega-3 supplementation helps cognition – perhaps due to serotonin – Feb 2015
- Omega 3 increased by 60 percent the ACTIVE vitamin D in the blood – Aug 2012
- Depression – is it reduced by Vitamin D and or Omega-3 – RCT 2019
- Typical pregnancy is now 39 weeks – Omega-3 and Vitamin D might restore it to full 40 weeks
- Fatty liver disease in children nicely treated by combination of Vitamin D and Omega-3 – RCT Dec 2016
- Live longer if high Vitamin D or Omega-3 (probably both)
- Improve Cognitive Health and Memory with Vitamin D and Omega-3 – World Patent March 2018
