Gum Arabic Can Reduce Body Fat

Ok, so...if you're reading this, we made it! Welcome to the "other side," the post-apocalyptic world.

Despite a relatively long history of use in foods, the researchers behind the new study claim that gum Arabic has not been extensively studied in humans. So the researchers recruited 120 healthy females with an average age of 20 and a mean BMI of 26.5 kg/m2 and randomly assigned them to consume 30 grams daily of gum Arabic or 1 gram daily of pectin (placebo) for six weeks.

Results showed that the gum Arabic group had a significantly reduced BMI by 0.32 and body fat by 2.18% over the six weeks, compared to baseline levels.

Some side effects – notably unfavorable viscous sensation in the mouth, early morning nausea, mild diarrhea and bloating abdomen – were reported by the gum Arabic group, but these were only observed for the first week, said the researchers.

“A recent proposed mechanism by which viscous dietary fibers were found to preserve lean body mass and reduce adiposity is increased mitochondrial biogenesis and fatty acid oxidation by skeletal muscles,” the researches wrote. “Gum Arabic’s mechanism is not yet fully elucidated, because of a small number of conducted studies.

Omega-3s Improve Cognitive Performance & Delay Onset of Cardiometabolic Disorders

Well, it's December 21, 2012... this could be the last Know Guff post you read...well, at least until next week.

A recently published randomized, controlled, cross-over study involving 40 healthy adults, ages 51-72 years old, found that omega-3 fatty acids improved cognitive function and lowered cardiometabolic risk factors after 5 weeks of supplementation. Subjects received either 3g daily fish oil or placebo for 5 weeks, separated by a 5 week washout period.


Zinc Improves Patients with Chronic Hepatitis C

I guess everything slows down during the Holiday Season, and that's true for the studies coming out. However, I did find this one on zinc supplements to share.

In a randomized, controlled study involving 62 patients with chronic hepatitis C (CH) or liver cirrhosis (LC), found that long-term zinc supplementation therapy may improve liver pathology and reduce the incidence of hepatocellular carcinoma (HCC).


Common Synthetic Antimicrobial Linked to Allergies in Children

Happy triple 12s! Apparently this is the last time most of us will experience another "triple" date. Well, not if I can help it. Keep reading this blog, every day, and I'll help you live until January 1st, 2101.  :)

Let's start with eliminating toxic chemicals in our lives. Triclosan is a synthetic broad-spectrum antimicrobial chemical used for more than 20 years to inhibit bacterial growth on skin and other surfaces. It's extremely common, and used It in toothpastes, mouthwashes, deodorants, soaps, plastic kitchenware. I remember even seeing this used in "kid-friendly" hand sanitizers sold through Toys R Us ("kid friendly" because it was triclosan, not ethanol, that was doing the killing).

However, triclosan is readily, and completely absorbed in the gastrointestinal tract and has been found in human urine, blood, plasma, and milk. Previous findings from the US National Health and Nutrition Examination Surveys showed a link between urinary triclosan concentrations and allergies in children. This new cross-sectional study conducted on Norwegian children with asthma confirms the results of the US study.


Vitamin D Slows Pre-Cancerous Growths

We already knew from numerous epidemiological studies that vitamin D can reduce cancer risk. Now, a team of researchers from Canada said they've discovered a new molecular mechanism on how this superstar vitamin provides protection from cancer. They report that the active form of vitamin D (1,25-dihydroxyvitamin D) acts to block cancer formation by several mechanisms that inhibit the production and function of a specific protein (known as cMYC), which is required for cell division.

The research team explains that cMYC drives cell division and is elevated in more than half of all cancers. The new findings, however, suggest vitamin D can alter this situation by not only inhibiting its production, but also accelerating its degradation. Vitamin D was also shown to strongly stimulate the production of an antagonist to cMYC, called MXD1, essentially shutting down cMYC function.


Potassium for Bone Health

New results from a randomised, double blind, placebo-controlled trial show that use of potassium supplements can help to boost bone mineral density and microarchitecture of bones in healthy older people.

In addition to supplementation with calcium and vitamin D, the research team found that those receiving the potassium had significantly increased bone mineral density and microarchitecture at a number of sites, including the lumbar spine.

While the benefits of potassium on blood pressure are well-established, this  new study offers an insight into the protective effects of potassium also on bone health. There are various mechanisms of how potassium can have this effect, but immediately, my thought was that potassium helps the body retain magnesium (which may also contribute to its blood pressure benefits). Magnesium is essential for proper bone health (and one of the best minerals you can take for cardiovascular health), and happens to be a mineral most people don't consume enough of.

By ensuring the body is supplied with sufficient potassium, it may help maintain magnesium levels, and if people aren't consuming enough magnesium, retaining even just a tiny bit more can potentially have great benefits.

This would be especially true for this study, where the participants were consuming calcium and vitamin D (since unbalanced calcium intake can promote a "relative deficiency" of magnesium). Ensuring a proper balance of calcium and magnesium in the body is important for many more aspect of health besides bone health.
