Vitamin A, which is an essential nutrient for humans, may be provided in the diet either as preformed vitamin A or as provitamin A carotenoids. The bioavailability of carotenoids in foods varies greatly, depending on many factors. Carotenoids are emulsified and then are solubilized in micellar form within the intestine with an absolute requirement for conjugated bile salts. Dietary carotenoids ...

Background Protein supplementation in addition to resistance training has been shown to increase muscle hypertrophy and lean mass. Supplemental protein sources differ in amino acid composition, size, structure, and functionality. Animal derived proteins sources such as Beef Protein Isolate (BeefISO), Serum Albumin Concentrate (SuperSerum), Serum Protein Concentrate (SerumPro), whey protein isol...

I . INTRODUCTION It is well known that L-ascorbic acid (AsA) has multifarious functions in our body. Humans who are unable to synthesize AsA in vivo have to absorb it as an essential nutrient from foods and some supplements. However, AsA is easily oxidized by oxygen in aqueous solutions, followed by oxidative degradation. To improve such instability, some derivatives including monoor di-substit...

Research on nutrient controls of planktonic productivity tends to focus on a few standard fractions of inorganic or total nitrogen (N) and phosphorus (P). However, there is a wide range in the degree to which land-derived dissolved organic nutrients can be assimilated by biota. Thus, in systems where such fractions form a majority of the macronutrient resource pool, including many boreal inland...

Increases in the growth rate of plants and microbes in the Mojave Desert in response to predicted increases in precipitation and CO2 due to global climate change may induce nutrient limitations. This study was designed to measure the pool of potentially bioavailable nutrients in soils of the Mojave Desert. Soils were collected from shrub and interspace microsites and then subjected to amendment...

ince the early 1970s, scientific evidence has shown that silicon is an essential nutrient for higher animals, including humans. Its role in human physiology is not fully defined, but it appears to be required for optimal growth and development of bone, cartilage, and connective tissues. Both metabolic and structural roles have been proposed. In bone, silicon is localized in active growth areas ...

In a world flooded with misinformation, the future of health and nutrition will be built on meaningful, tangible results. The most impactful “NEWS” that needs to shared is protein supplements are not all what they cracked up be. Let’s first agree best source should come from whole foods!

Vet Med Today: Timely Topics in Nutrition 593 R (Oryza sativa) is one of the most important cereal crops in the world. It is a dietary staple that provides the bulk of daily calories for many companion animals and humans. The bran fraction of rice is a nutrient-rich by-product that has been primarily used as a low-cost feed for livestock and a fiber source in pet food. This review highlights ar...

Accumulation of phosphate and ammonia in estuarine systems and subsequent dinoflagellate and algal blooms has been implicated in fish kills and in health risks for fishermen. Analytic chemistry kits are used to measure phosphate and ammonia levels in water samples, but their sensitivity is limited due to specificity for inorganic forms of these moieties. An Escherichia coli bioluminescent repor...

Flavonoids are a group of phytochemicals that have shown numerous health effects and have therefore been studied extensively. Of the six common food flavonoid classes, flavonols are distributed ubiquitously among different plant foods whereas appreciable amounts of isoflavones are found in leguminous plant-based foods. Flavonoids have shown promising health promoting effects in human cell cultu...
