Who wouldn’t want a biscuit? Not a diabetic or anyone else fearing a high-glycemic response. Not more than one or two at least. But will a patented, highly viscous fiber blend change how we enjoy starchy-tasting snacks? Croatian food scientists who have been studying the fiber blend reported that, when included as an ingredient in biscuits, it was successful in maintaining healthy blood sugar levels (1). The researchers tested the fiber biscuits… Read More

My goal is to keep my glycemic load (GL) under 100 daily so let’s see how I did today (all data from NutritionData.com): Highest GL foods 2tbsp Honey (in my oatmeal) GL=20 1 Starbucks Caramel Mocha Frappuccino® Light Blended Creme GL=161 Plain Bagel GL=17 1 cup White Rice (with sushi) GL=181 packet Instant Oatmeal GL=10 Lowest GL foods 2 tbsp Sugar (with my green tea) GL=61 large Peach GL=51 Watermelon wedge GL=61… Read More

Strong evidence exists that low-glycemic and low-glycemic-load diets reduce risk of diabetes mellitus, obesity, insulin resistance, cardiovascular disease and cancer (1-4). However, glycemic index and glycemic load are subject of controversy among nutritionists because they are inconsistent in their findings due to high variability, are poorly standardized and their results are difficult to reproduce (1;2). Despite methodological problems, however, studies are showing glycemic index and glycemic load are effective as clinical tools… Read More

What is hemosiderosis? Most iron is stored in the liver, lymph and skeletal muscles by use of a protein, ferritin (1). Ferritin consists of an apoprotein called apoferritin that is made up of H and L subunits (amino acids) synthesized dependent on concentration of free intracellular iron (1). Each protein can hold up from 3000 to 4500 iron atoms (1). When overload exceeds storage capacity, however, a partially degraded form of ferritin… Read More

Overview Dyshemoglobinemias are mainly caused by exposure to exogenous xenobiotics although it can be hereditary (1). The occurrence is result of altered hemoglobin (Hb) preventing its normal function of carrying oxygen (1). The anemia, hypoxia, cyanosis and associated problems can be life-threatening (2). Causes Acquired methemoglobinimeas occur when dysfunctional hemoglobin form methemoglobin, whereas mutated amino acids make up a wall against heme or form the site involved in binding oxygen (3). Carboxyhemoglobinemia… Read More

Iron is abundant in the world and needed by every living organism. For this reason early in evolution multi-cellular organisms evolved antimicrobial peptides(1). Without them we just wouldn’t be able to survive the onslaught of microbial growth (1). In addition, free iron in plasma has redox capabilities that can also be toxic. The toxicity is due to the Haber-Weiss-Fenton sequence, which forms hydroxyl radicals due to superoxide after reduction of dioxygen (1)…. Read More

Just in case anyone’s interested, I had the great opportunity to discuss nutrition science today with none other than Lucy discoverer Donald Johanson. What luck! After explaining to Johanson of studying “evolutionary discordance” of diet post-agricultural revolution, he pointed me in the direction of a book related to hominin diets based on studies of hominin teeth. This revelation led me to have a great interest in what further studies could be put… Read More

Purpose of study: To evaluate potential treatment with use of n-3 fatty acids for those with mild to moderate Alzheimer’s disease (AD). Research methodology: Randomized, double-blind, placebo-controlled clinical trial Description: Researchers treated 204 patients with mild to moderate AD (ages 74 +- 9) with n-3 fatty acids or placebo for 6 months. All patients then received n-3 fatty acid treatment for the following 6 months. No cross-over trial was performed. Patients were… Read More

Purpose of review: Further research was necessary into relationship between fish consumption and risk of stroke because observational studies were inadequate for determining relationship. Review strategy: Meta-analysis on cohort studies relating to fish consumption and risk of stroke. Description: Researchers searched Medline and Embase databases with relative keywords (e.g. “fish) to identify 9 total relevant cohorts (note: one study counted as two) published in English language journals from 1966 to 2003. The… Read More
