Nutrition RSS FeedsDoes Raspberry Ketone Promote Weight Loss? - Raspberry ketone is an aromatic compound found in red raspberries. It's extracted and used in perfumes and cosmetics and it's also used as a flavoring agent in some fruit-flavored foods. Apparently now it's being touted as a semi-magical weight loss aid. But does it work? Who knows - I can't find any clinical studies for it. There are some studies on mice that were given raspberry ketone and it appeared to prevent weight gain when the little rodents were fed high-fat diets. Apparently the anti-obesity effects were due to stimulation of lipolysis (which is how the body breaks down fat in fat cells called adipocytes) in both regular fat tissue and brown fat tissue. It also suppressed release of pancreatic lipase, a digestive enzyme needed to break down dietary fats so they can be absorbed through the small intestinal wall. But this research was done on mice. We're humans, not rodents. We have different physiology and different emotional reasons for eating (or not eating) ...Feed Source: nutrition.about.com Tomatoes - A Superfood - Tomatoes are the kind of superfood I really like. They're easy to find, easy to prepare and cooking or processing them doesn't reduce the health benefit you may get from eating them. Now, I don't consider a blob of ketchup to be a vegetable and I realize you can find tomato sauce buried in some unhealthy places, like under layers of cheese and sausage on a pizza, but it's always nice when a superfood is something simple. Tomatoes are proof that superfoods don't have to be exotic or difficult to find.
Today I wrote about the health benefits of tomatoes, and now I think I'm craving a tomato, basil and mozzarella cheese salad. Read about the Health Benefits of TomatoesDo you like tomatoes? What's your favorite kind of tomato and how do like to eat them?... Drinking Water - Good nutrition isn't just about the foods you eat, it also includes the beverages you drink. Water is a good beverage. It doesn't have any calories or artificial colorings or flavorings and your body needs it. It's also cheap when you get it from the tap. Maybe you prefer bottled water or you use a filtered pitcher to avoid impurities or you prefer the flavor.
I don't like to drink water. I don't like the way it tastes. A lot of people think that's weird because water doesn't really have any flavor. I was a picky eater as a kid so maybe that's related, I don't know. Anyway, if you're like me you can still get enough water by choosing other beverages or flavoring your water with a slice of lemon or lime. I also like sparkling water. You can choose flavored waters too. Just because they're flavored doesn't change the fact that they're almost completely water.

... Sweet Potatoes - Did you know that yams and sweet potatoes are a great source of vitamin A and beta carotene? Sweet potatoes are also a good source of fiber. They have a naturally sweet flavor that doesn't need much extra seasoning, although they're often glazed or served in sweet potato pie. Today I wrote an article about sweet potatoes, how to choose them, how to cook them and I included some links to healthy and delicious recipes that feature sweet potatoes:
Super Sweet Potatoes
What's your favorite way to serve sweet potatoes? I like mine baked and then served with a little bit of real maple syrup with a few pecans sprinkled on top.Sweet Potatoes originally appeared on ... Vitamin D In the Winter - Vitamin D is a popular vitamin in the world of nutrition right now - it seems there's news about vitamin D research every week. Your body needs vitamin D in order to absorb calcium and various research studies have linked deficiencies with several health conditions, including high blood pressure and cardiovascular disease. Today I read a study published in the American Journal of Cardiology in which the authors looked at vitamin D deficiency, supplementation and cardiovascular disease risk factors like high blood pressure and diabetes. The researchers (not surprisingly) found an association of vitamin D deficiency with an increased risk of cardiovascular disease and also with decreased survival time. So they looked a little closer at the patients w... Dietary Magnesium and Stroke Risk - A study published in the American Journal of Clinical Nutrition came to the conclusion that dietary magnesium intake is inversely associated with the risk of ischemic stroke (these are the strokes caused by blood clots in the brain). The authors performed a meta-analysis, which is a type of study that involves taking the data from previous similar studies and combining them. The authors of the study used the data from seven previous studies and determined that an increased intake of 100 milligrams magnesium per day was associated with an 8 - 9% decreased risk of ischemic stroke. Eight or nine percent may not sound like much, but according to the ... Nutritionist or Dietitian? - A reader wants to know if there's a difference between nutritionists and dietitians?

Paula Deen's Diabetes - I don't usually do much celebrity blogging, but the news about Paula Deen's being diagnosed with type II diabetes is interesting. I wish her the best in coping with diabetes and all the potential health issues that come with it.
I can't say I watch her show very often (I prefer Anthony Bourdain). For me, too much of what she creates in her kitchen could qualify as "Food Porn" because of it's high-calorie decadence. And yep, eating too much high-calorie food leads to weight gain that increases your risk for diabetes and other health problems like cardiovascular disease a...

Post Holiday Sweet Tooth - The first week in January is a big week for dietary clean-ups, including cutting back on added sugars. Although I don't indulge in too many sweet holiday treats beyond my usual chocolate fix, by January I'm ready for more green and colorful vegetables, fresh fruits and simpler meals. But if (like me) you're cursed with a raging sweet tooth, how do you tame your craving for sweets?
... Periodic 48h feed withdrawal improves glucose tolerance in growing pigs by enhancing adipogenesis and lipogenesis - Background:
Adipocyte numbers and peroxisome proliferators activated receptorgamma (PPARgamma) expression of retroperitoneal tissue increased while area under the curve (AUC) during the glucose tolerance test (GTT) was reduced in rats subjected to certain feed withdrawal (FW) regimens. Thus, using pigs as the experimental model, the hypothesis that FW regimens influence glucose tolerance by influencing fat cell function was evaluated with the objective of determining the effect of a single (FWx1; at age of 19 wk for 48 h) or periodic, multiple (FWx4; 24 h FW at 7 and 11 wk of age and 48 h FW at 15 and 19 wk of age) FW on AUC of glucose and insulin during the GTT relative to pigs that did not experience FW (Control).
Methods:
Growth, body composition, adipocyte numbers, PPARgamma expression, lipogenic potential as glucose uptake into fat of adipocytes of varying diameter in omental (OM) and subcutaneous (SQ) fat as affected by FW regimens were determined in pigs initiated into the stud... The chronic effects of fish oil with exercise on postprandial lipaemia and chylomicron homeostasis in insulin resistant viscerally obese men - Background:
Visceral obesity and insulin resistance are associated with a postprandial accumulation of atherogenic chylomicron remnants that is difficult to modulate with lipid-lowering therapies. Dietary fish oil and exercise are cardioprotective interventions that can significantly modify the metabolism of TAG-rich lipoproteins. In this study, we investigated whether chronic exercise and fish oil act in combination to affect chylomicron metabolism in obese men with moderate insulin resistance.
Methods:
The single blind study tested the effect of fish oil, exercise and the combined treatments on fasting and postprandial chylomicron metabolism. Twenty nine men with metabolic syndrome were randomly assigned to take fish oil or placebo for four weeks, before undertaking an additional 12 week walking program. At baseline and at the end of each treatment, subjects were tested for concentrations of fasting apo B48, plasma lipids and insulin. Postprandial apo B48 and TAG kinetics were a... Flaxseed dietary fibers lower cholesterol and increase fecal fat excretion, but magnitude of effect depend on food type - Background:
Dietary fibers have been proposed to play a role in cardiovascular risk as well as body weight management. Flaxseeds are a good source of dietary fibers, and a large proportion of these are water-soluble viscous fibers.MethodHere, we examine the effect of flaxseed dietary fibers in different food matrices on blood lipids and fecal excretion of fat and energy in a double-blind randomized crossover study with 17 subjects. Three different 7-d diets were tested: a low-fiber control diet (Control), a diet with flaxseed fiber drink (3/day) (Flax drink), and a diet with flaxseed fiber bread (3/day) (Flax bread). Total fat and energy excretion was measured in feces, blood samples were collected before and after each period, and appetite sensation registered 3 times daily before main meals.
Results:
Compared to control, Flax drink lowered fasting total-cholesterol and LDL-cholesterol by 12 and 15%, respectively, (p... Phenylketonuria: nutritional advances and challenges - Despite the appearance of new treatment, dietary approach remains the mainstay of PKU therapy. The nutritional management has become complex to optimize PKU patients' growth, development and diet compliance. This paper review critically new advances and challenges that have recently focused attention on potential relevant of LCPUFA supplementation, progress in protein substitutes and new protein sources, large neutral amino acids and sapropterin. Given the functional effects, DHA is conditionally essential substrates that should be supplied with PKU diet in infancy but even beyond. An European Commission Programme is going on to establish quantitative DHA requirements in this population. Improvements in the palatability, presentation, convenience and nutritional composition of protein substitutes have helped to improve long-term compliance with PKU diet, although it can be expected for further improvement in this area. Glycomacropeptide, a new protein source, may help to support... D-Lactate Altered Mitochondrial Energy Production in Rat Brain and Heart but not Liver - Background:
Substantially elevated blood D-lactate (DLA) concentrations are associated with neurocardiac toxicity in humans and animals. The neurological symptoms are similar to inherited or acquired abnormalities of pyruvate metabolism. We hypothesized that DLA interferes with mitochondrial utilization of L-lactate and pyruvate in brain and heart.
Methods:
Respiration rates in rat brain, heart and liver mitochondria were measured using DLA, LLA and pyruvate independently and in combination.
Results:
In brain mitochondria, state 3 respiration was 53% and 75% lower with DLA as substrate when compared with LLA and pyruvate, respectively (p... Quality protein intake is inversely associated with abdominal fat - Dietary protein intake and specifically the quality of the protein in the diet has become an area of recent interest. This study determined the relationship between the amount of quality protein, carbohydrate, and dietary fat consumed and the amount of times the ~10g essential amino acid (EAA) threshold was reached at a meal, with percent central abdominal fat (CAF). Quality protein was defined as the ratio of EAA to total dietary protein. Quality protein consumed in a 24-hour period and the amount of times reaching the EAA threshold per day was inversely related to percent CAF, but not for carbohydrate or dietary fat. In conclusion, moderate to strong correlations between variables indicate that quality and distribution of protein may play an important role in regulating CAF, which is a strong independent marker for disease and mortality.... High prevalence of gastroesophageal reflux symptoms in type 2 diabetics with hypoadiponectinemia and metabolic syndrome - Background:
The prevalence of gastroesophageal reflux disease (GERD) has been increasing worldwide. Abdominal obesity or visceral fat accumulation rather than simple obesity is associated with GERD. Previous reports demonstrated the association between GERD and type 2 diabetes mellitus (T2DM). Signification of visceral fat accumulation and adiponectin in T2DM patients with GERD remains unclear. The present study investigated the relationships between GERD symptoms, visceral fat accumulation and adiponectin in subjects with T2DM.FindingsThe study (ADMIT study) subjects were 66 Japanese T2DM outpatients, who answered the questionnaire regarding GERD symptoms in Frequency Scale for the Symptoms of GERD (FSSG), and were measured visceral fat area by bioelectrical impedance analysis. Patients with FSSG scores of more than 8 were considered as positive. The prevalence of FSSG score >8 and average FSSG score in T2DM subjects with the metabolic syndrome (Mets) were significantly higher compare... A high calcium diet containing nonfat dry milk reduces weight gain and associated adipose tissue inflammation in diet-induced obese mice when compared to high calcium alone - Background:
High dietary calcium (Ca) is reported to have anti-obesity and anti-inflammatory properties. Evidence for these properties of dietary Ca in animal models of polygenic obesity have been confounded by the inclusion of dairy food components in experimental diets; thus, effect of Ca per se could not be deciphered. Furthermore, potential anti-inflammatory actions of Ca in vivo could not be dissociated from reduced adiposity. Methods: We characterized adiposity along with metabolic and inflammatory phenotypes in diet-induced obese (DIO) mice fed 1 of 3 high fat diets (45% energy) for 12 wk: control (n = 29), high-Ca (n = 30), or high-Ca + nonfat dry milk (NFDM) (n = 30). Results: Mice fed high-Ca + NFDM had reduced body weight and adiposity compared to high-Ca mice (P < 0.001). Surprisingly, the high-Ca mice had increased adiposity compared to lower-Ca controls (P < 0.001). Hyperphagia and increased feed efficiency contributed to obesity development in high-Ca mice, in cont... Population prevalence, attributable risk, and attributable risk percentage for high methylmalonic acid concentrations in the post-folic acid fortification period in the US - Background:
Serum methylmalonic acid (MMA) is regarded as a sensitive marker of vitamin B-12 status. Elevated circulating MMA is linked to neurological abnormalities. Contribution of age, supplement use, kidney dysfunction, and vitamin B-12 deficiency to high serum MMA in post-folic acid fortification period is unknown.
Methods:
We investigated prevalence, population attributable risk (PAR), and PAR% for high MMA concentrations in the US. Data from 3 cross-sectional National Health and Nutrition Examination Surveys conducted in post-folic acid fortification period were used (n=18569). Results: Likelihood of having high serum MMA for white relative to black was 2.5 (P... Gamma-tocotrienol does not substantially protect DS neurons from hydrogen peroxide-induced oxidative injury - Background:
Down syndrome (DS) neurons are more susceptible to oxidative stress and previous studies have shown that vitamin E was able to reduce oxidative stress and improve DS neurons' viability. Therefore, this study was done to investigate the protective role of gamma-tocotrienol (gT3) in DS neurons from hydrogen peroxide (H2O2) -induced oxidative stress. The pro-apoptosis tendency of gT3 was compared to alpha-tocopherol (aT) in non-stress condition as well.
Methods:
Primary culture of DS and euploid neurons were divided into six groups of treatment: control, H2O2, gT3 pre-treatment with H2O2, gT3 only, aT pre-treatment with H2O2 and aT only. The treatments were assessed by MTS assay and apoptosis assay by single-stranded DNA (ssDNA) apoptosis ELISA assay, Hoechst and NeuN immunofluorescence staining. The cellular uptake of gT3 and aT were determined by HPLC while protein expressions were determined by Western blot. Comparison between groups was made by the Student's t test, one...
