BlogOur Scientists post interesting observations and research here. Mycotoxins and Endotoxin Content Vary Between Different Batches of Grain-Based Diets
By Sridhar Radhakrishnan, Ph.D..
by Sridhar Radhakrishnan, Ph.D. and Michael Pellizzon, Ph.D. - Research Diets, Inc. We measured endotoxins in at least 3 separate lots of 5 different GB diets as well as the purified diets D11112201 (15 kcal% fat), D12492 (60 kcal% fat) and... Diet is important in changing the microbiome

Our invited paper entitled “Effects of Rodent Diet Choice and Fiber Type on Data Interpretation of Gut Microbiome and Metabolic Disease Research” is available online as an epub and was made open access by Current Protocols in Toxicology. Research Diets scientist quoted in Nature article
By Mark D'Antonio.
In last month’s Nature Medicine, Dan Engber wrote a nice article about the efforts to standardize high-fat diets to make rodents obese, and the pitfalls of a ‘one diet fits all’ approach. He also points out the lack of attention that is generally... Fiber Is Good for You. Now Scientists May Know Why.

By Mark D'Antonio.
Diets used to induce metabolic disease are generally high in fat and refined carbohydrates and importantly, are usually made with refined, purified ingredients. However, researchers will often use a low fat grain-based (GB) diet containing... Are you choosing the right diets to make your mice fat?
By Sridhar Radhakrishnan, Ph.D..
A recently published review article summarizes multiple studies in this area and has revealed some startling observations. Read moreIntestinal Health: Are you choosing the right type of diet for your lab animals?
By Steven Yeung, M.S..
Are you familiar with the difference between a grain based chow and a purified ingredient diet? RDI's Senior Scientist Dr.Michael Pellizzon talks about differences between these two types of diets and how they can influence the intestinal health... Does Diet matter when performing animal imaging studies?
By Matthew Ricci, Ph.D..
If your study involves in vivo imaging using fluorescence technologies, it's very important that the 'background' or 'noise' signal be as low as possible. Unfortunately, many commonly used grain-based chow diets contain chlorophyll, which fluoresces at 680 nm and can therefore interfere with the detection of fluorophores. The result is that the GI tract of the animal will fluoresce and your signal of interest may be hard or impossible to quantify. Read moreCategoriesTagsLatest Posts
