Byte-Sized Summary: Osteoarthritis is a common but debilitating joint disease, commonly of the knee, with unknown causes. A recent study has found that the prevalence of the condition has nearly doubled, and that longevity and BMI alone to not explain the increase. Researchers at Harvard published their research on the disease in the Proceedings of the National … Continue reading Why is knee pain on the rise?
We all know that protein is made of amino acids, but have you ever wondered why a Nutrition Facts label on your food says "protein", even though the amino acids are different? To keep this post "byte sized", we focusing only on foods here. First, Protein content may be calculated on the basis of the … Continue reading How is protein defined?
Halitosis or Bad Breath (and, suggested by Google, "Mouth Breathers"!) may have light at the end of the tunnel Researchers in Brazil tried to cure Halitosis by shining light on tongues: to treat oral halitosis in healthy adults with photodynamic therapy (PDT), associated with periodontal treatment and follow them up for 3 months. As background, … Continue reading Cure Bad Breath with Light Beams
Your weight, too, impacts how your gut bacteria respond to exercise: ...exercise training induces compositional and functional changes in the human gut microbiota that are dependent on obesity status, independent of diet and contingent on the sustainment of exercise Researchers at UIUC in Illinois evaluated changes in the gut microbiome in lean and obese participants … Continue reading Exercise Alters Gut Microbiota Composition and Function in Lean and Obese Humans
Additional research suggesting supplementing with potassium bicarbonate may reduce age-related loss of muscle. Note that the primary endpoints of this study are on nitrogen excretion (e.g. urinary ammonia nitrogen), and not direct lean mass. Email or leave comments for questions, more on this topic soon! 14 healthy postmenopausal women residing in a General Clinical Research … Continue reading Bicarbonate supplements may reduce age-related muscle loss
Decent sized study, but other endpoints needed before too many conclusions drawn... The acid load accompanying modern diets may have adverse effects on bone and muscle metabolism. Treatment with alkaline salts of potassium can neutralize the acid load, but the optimal amount of alkali is not established. Our objective was to determine the effectiveness of … Continue reading Potassium Bicarbonate Supplementation Lowers Bone Turnover and Calcium Excretion in Older Men and Women
For those interested in preserving muscle mass: Subjects were 384 men and women > or =65 y old who participated in a 3-y trial comparing calcium and vitamin D with placebo. Potassium was measured in 24-h urine collections at baseline. The %LBM, defined as total body nonfat, nonbone tissue weight/weight x 100, was measured by … Continue reading Aging Adults Preserve Muscle Mass with Potassium from Fruits and Veggies
Background We aimed to investigate the association between carbohydrate intake and mortality.Methods ...we assessed whether the substitution of animal or plant sources of fat and protein for carbohydrate affected mortality.Interpretation of results Low carbohydrate dietary patterns favouring animal-derived protein and fat sources, from sources such as lamb, beef, pork, and chicken, were associated with higher … Continue reading Mortality Rates Associated with Replacing Dietary Carbohydrate with Plant vs Animal Protein
"What is clear is that genetic susceptibility plays an important role in the development of IBD, and large genome-wide association studies using case-control approaches have identified more than 230 risk alleles. Many of these identified risk alleles are located in a variety of genes important in host-microbiome interactions. In spite of these major advances, the … Continue reading Comment on the genetics and microbiome of Irritable Bowel Syndrome
Cinnamaldehyde (CA) is a food compound that has previously been observed to be protective against obesity and hyperglycemia in mouse models. In this study, we aimed to elucidate the mechanisms behind this protective effect by assessing the cell-autonomous response of primary adipocytes to CA treatment. That is from researchers in Michigan and China, published in … Continue reading Cinnamon and Obesity
