BACKGROUND: Aberrations in the activities of key enzymes of carbohydrate metabolism is well documented in diabetes mellitus. Previous studies have shown that active ingredients in the extracts of Berberis aristata exhibits diverse pharmacological activities in animal models. OBJECTIVE: The present study was undertaken to investigate whether berbamine (BBM), an alkaloid from the roots of Berberis aristata can ameliorate the altered activities of carbohydrate metabolic enzymes in high fat diet (HFD)/streptozotocin (STZ) induced diabetic rats...

PURPOSE OF REVIEW: Summarize the physiological effects of low-carbohydrate diets as they relate to weight loss, glycemic control, and metabolic health. RECENT FINDINGS: Low-carbohydrate diets are at least as effective for weight loss as other diets, but claims about increased energy expenditure and preferential loss of body fat are unsubstantiated. Glycemic control and hyperinsulinemia are improved by low-carbohydrate diets, but insulin sensitivity and glucose-stimulated insulin secretion may be impaired, especially in the absence of weight loss...

To evaluate the long-term impacts of early life nutritional manipulations on glucagon secretion and hepatic signalling, thirty-six twin pregnant ewes during their last trimester were exposed to NORM (fulfilling 100% of daily energy/protein requirements), HIGH (fulfilling 150/110% of daily energy/protein requirements) or LOW (50% of NORM) diets. Twin lambs were assigned after birth to a moderate (CONV) or high-carbohydrate-high-fat (HCHF) diet until six months. Then responses in plasma glucagon concentrations and glucagon ratios relative to previously reported values for insulin, glucose and lactate were determined after intravenous bolus injections of glucose or propionate (fed and 2-days fasting state)...

BACKGROUND: Gut microbes influence their hosts in many ways, in particular by modulating the impact of diet. These effects have been studied most extensively in humans and mice. In this work, we used whole genome metagenomics to investigate the relationship between the gut metagenomes of dogs, humans, mice, and pigs. RESULTS: We present a dog gut microbiome gene catalog containing 1,247,405 genes (based on 129 metagenomes and a total of 1.9 terabasepairs of sequencing data)...

Rather than maximizing intake of available macronutrients, insects increase intake of some nutrients and restrict intake of others. This selective consumption influences, and potentially optimizes developmental time, reproduction and lifespan of the organism. Studies so far have focused on discriminating between protein and carbohydrate and the consequences on fitness components at different life stages. However, it is largely unknown if and how the developmental diets, which may entail habitat specific nutrient restrictions, affect the selective consumption of adults...

A dietary regimen of caloric restriction delays aging in evolutionarily distant eukaryotes, including the budding yeast Saccharomyces cerevisiae . Here, we assessed how caloric restriction influences morphological, biochemical and cell biological properties of chronologically aging yeast advancing through different stages of the aging process. Our findings revealed that this low-calorie diet slows yeast chronological aging by mechanisms that coordinate the spatiotemporal dynamics of various cellular processes before entry into a non-proliferative state and after such entry...

The study aimed to evaluate the consequences of the consumption of a high-fructose diet (HFR; fructose was responsible for 45% of the energy from carbohydrates) by the mother, the father, or both on C57BL/6 adult male offspring. Non-consanguineous parents received the diet (HFR or control, C) from 8 weeks before mating until weaning (n=10 fathers and n=10 mothers on each diet). After weaning, only the C diet was offered to offspring. The groups were formed by one male randomly taken from each litter. The offspring groups were identified according to the mother's diet (the first letter), then the father's diet (the second letter), that is, C/C, C/HFR, HFR/C, HFR/HFR (n=10 per group)...

Cowpea (Vigna unguiculata) is a legume consumed as a high-quality plant protein source in many parts of the world. High protein and carbohydrate contents with relatively low fat content and complementary amino acid pattern to that of cereal grains make cowpea an important nutritional food in the human diet. Cowpea has gained more attention recently from consumers and researchers worldwide due to its exerted health beneficial properties including anti-diabetic, anti-cancer, anti-hyperlipidemic, anti-inflammatory and anti-hypertensive properties...

A 20-year-old female was diagnosed with ulcerative colitis (UC) at age 14 and primary sclerosing cholangitis (PSC) at age 16. The PSC was successfully treated with high doses of oral vancomycin; however, the UC was more difficult to manage. After many drug treatments failed to treat the UC, the patient began following the specific carbohydrate diet (SCD). This report documents fecal microbiome changes resulting from following the SCD for two weeks. The DNA extracted from fecal samples was subjected to 16S rRNA gene sequencing to quantify bacterial species abundance...

The ketogenic diet (KD) is a high-fat, adequate-protein, and low-carbohydrate diet that has been used successfully in the treatment of refractory epilepsies for almost 100 years. There has been accumulating evidence to show that the KD may provide a therapeutic benefit in autism spectrum disorders, albeit by a yet-unknown mechanism. We report a case of a 6-year-old patient with high-functioning autism and subclinical epileptic discharges who responded poorly to several behavioural and psychopharmacological treatments...

BACKGROUND AND PURPOSE: Elevated postprandial blood glucose is a critical risk factor for stroke. The dietary glycemic load (GL) and glycemic index (GI) are frequently used as markers of the postprandial blood glucose response to estimate the overall glycemic effect of diets. We hypothesized that high dietary GL, GI, or total carbohydrate intake is associated with a poor functional outcome in patients with acute ischemic stroke. METHODS: We prospectively included 263 first-ever ischemic stroke patients who completed a semiquantitative food-frequency questionnaire...

Nitric oxide (NO) is synthesized not only from L-arginine by NO synthases (NOSs), but also from its inert metabolites, nitrite and nitrate. Green leafy vegetables are abundant in nitrate, however whether or not a deficiency in dietary nitrite/nitrate spontaneously causes disease remains to be clarified. In this study, we tested our hypothesis that long-term dietary nitrite/nitrate deficiency induces metabolic syndrome (MetS) in mice. To this end, we prepared a low nitrite/nitrate diet (LND) consisting of an amino acid-based low nitrite/nitrate chow in which the contents of L-arginine, fat, carbohydrates, protein, and energy were identical with a regular chow, and potable ultrapure water...

Many early studies laid the foundation for our understanding of the mechanics of chewing, the physiological role of chewing for the cow, and how chewing behavior is affected by dietary characteristics. However, the dairy cow has changed significantly over the past decades, as have the types of diets fed and the production systems used. The plethora of literature published in recent years provides new insights on eating and ruminating activity of dairy cows. Lactating dairy cows spend about 4.5 h/d eating (range: 2...

BACKGROUND: Low-carbohydrate, ketogenic diets cause mild, sub-clinical systemic acidosis. Anaerobic exercise performance is limited by acidosis. Therefore, we evaluated the hypothesis that a low-carbohydrate, ketogenic diet impairs anaerobic exercise performance, as compared to a high-carbohydrate diet. METHODS: Sixteen men and women (BMI, 23±1 kg/m2, age 23±1 yr) participated in a randomized-sequence, counterbalanced crossover study in which they underwent exercise testing after four days of either a low-carbohydrate, ketogenic diet (LC; <50 g/day and <10% of energy from carbohydrates) or a high-carbohydrate diet (HC; 6-10 g/kg/day carbohydrate)...

Bos indicus typically perform better than Bos taurus when consuming a low-quality diet; however, the response to supplementation is generally greater in B. taurus. The underlying mechanisms supporting these responses have not been fully elucidated. Characterization of differences in rumen prokaryotic populations and their functional role in the two subspecies may provide additional insight. Ten cannulated steers (5 Angus and 5 Brahman) were used in concurrent 5 × 5 Latin squares. Animals were offered ad libitum access to rice straw (4...

Tree nuts, complete functional foods, contain macro- and micronutrients of high biological value. These bioactive compounds have a synergistic effect in preventing and delaying many age-related pathologies (e.g. cardiovascular diseases, stroke, type 2 diabetes mellitus, certain types of cancer, and several neurodegenerative diseases). Tree nuts are low in carbohydrates, but they abound in healthy fatty acids, in optimal proportion for a good plasma lipid profile, and are a good source of proteins, rich in proteinogenic amino acids...

Impaired mitochondrial function often results in excessive production of reactive oxygen species (ROS) and is involved in the etiology of many chronic diseases, including cardiovascular disease, diabetes, neurodegenerative disorders, and cancer. Moderate levels of mitochondrial ROS, however, can protect against chronic disease by inducing upregulation of mitochondrial capacity and endogenous antioxidant defense. This phenomenon, referred to as mitohormesis, is induced through increased reliance on mitochondrial respiration, which can occur through diet or exercise...
