Thanks for visiting! My goal here is to discuss the latest scientific research to separate the good from all that "guff" in nutritional sciences and all aspects of human health. Because the more you Know, well...the more you Know!

B Vitamins for Cataracts

Increased dietary intakes of B vitamins are associated with reduced incidence and decreased risks of developing different forms of cataracts in older people, says new data from the Age-Related Eye Disease Study (AREDS) Research Group.


How to Speed Up the Brain's Visual Processing

I realized I had a number of studies I wanted to share with you from back in June that I just didn't have time to write about. So although the next few studies are maybe a little old (by a couple months), I'm sure you'll still find them not only A) interesting, but B) since these were not picked up by mass media, they'll also seem fresh and new...or at least we can pretend.  :)


Exercise May REVERSE Alzheimer's Disease

New research recently discussed at the Alzheimer's Association International Conference a few weeks ago showed that being physically active not only reduces cognitive decline and improves neuropsychiatric symptoms in patients with dementia, but may actually reduce the level of biomarkers of Alzheimer's disease (AD), including amyloid and tau protein.

The first study I'll discuss today showed that older adults with mild to moderate AD who had at least 80% adherence to an aerobic exercise program and maintained at least 70% of their maximum heart rate (the "high exercise" group, which was prescribed 1 hour of aerobic exercise three times a week for 16 weeks) had a statistically significant advantage on the Symbol Digit Modalities Test (SDMT) over a control group.


Teen Cannabis Use Lacks Long-Term Consequences

Cannabis use has not only been proven to be safe, but also multitudes of order less damaging to society and personal health than alcohol and tobacco. The only real controversy--in my opinion--is with respect to long-term consequences from usage in teenage years. This study adds some more evidence that cannabis use in teenagers is safe and lacks long-term consequences, very similar to another study I covered a few months back (click HERE for that study).

However, even though this was a well-designed study that overcame many of the limitations of prior studies, I urge caution in allowing teenagers to use cannabis freely--there's just too much conflicting information at this time. As for adults, those who know me will know I'm a big advocate, and based on its safety profile and medicinal benefits, I say most adults can use it freely as desired.

Now let's take a closer look at this current study...


Smoking (Tobacco) & Menopausal Hot Flashes

A newly published study has not only confirmed that smoking tobacco exacerbates menopausal hot flashes, but has also revealed that quitting can ameliorate hot flashes. Here is what the results showed:


Carotenoids, Macular Pigments, and Contrast Sensitivity

Although every sense is important, most would agree that vision is at the top of the list. Unfortunately, many of us don't consider taking preventative approaches to protecting eye health until it's too late. Why that's unfortunate is that we now have significant amounts of nutritional studies that show that specific ingredients and supplements can help reduce the risk of age-related macular degeneration (AMD, which is the leading cause of blindness). As such, today I share with you a newly published study that showed some interesting data that adds to our knowledge base.


Asthma Medication May Make Asthma Worse

Inhaled corticosteroids cannot adequately protect children with asthma from high levels of air pollution, according to a newly published study. In fact, the results show that they may actually exacerbate the effects of air pollutants!


Antibiotics Linked to Arthritis in Kids

Recent evidence has linked childhood antibiotic use and microbiome disturbance to autoimmune conditions. This study tested the hypothesis that antibiotic exposure was associated with newly diagnosed juvenile idiopathic arthritis (JIA).


Cannabis Effective for Diabetic Neuropathy

Another positive study on the medicinal benefits of cannabis. This time it showed that inhaled cannabis can blunt the pain of diabetic neuropathy without seriously impairing cognitive function.

The study appears to be the first randomized controlled trial of inhaled cannabis for diabetic neuropathy pain, and is quickly becoming an increasingly common condition (given the increasing prevalence of diabetes). This study is welcome news since currently approved medications don't provide adequate relief to most patients with this condition.


Smoke from Wildfires Linked to Heart Attacks

Here's some info for all those in Western Canada and the US, as they struggle to contain the ongoing wildfires. A newly published study shows exposure to PM2.5 (particulate matter less than 2.5 micrometres in diameter) was associated with an upswing in out-of-hospital heart attacks in men and ischemic heart disease (IHD) events in women.
