When evaluating clinical studies to establish a `single truth' about saturated, monounsaturated, or polyunsaturated fat on the one hand, or dietary cholesterol on the other, how does one account for the relative importance of individual fatty acids or dietary cholesterol (Hayes, 1995; Khosla & Sundram, 1996). The statement that: `saturated fatty acids (SFA)(More)
Waste from agricultural products represents a disposal liability, which needs to be addressed. Palm oil is the most widely traded edible oil globally, and its production generates 85 million tons of aqueous by-products annually. This aqueous stream is rich in phenolic antioxidants, which were investigated for their composition and potential in vitro(More)
Polydextrose is a randomly bonded polysaccharide produced by the bulk melt polycondensation of glucose and sorbitol in vacuo. It has been used as a bulking and texturizing agent and soluble fiber ingredient in many food products worldwide for over two decades. Because of its atypical linkages between glucose moieties, polydextrose resists digestion by(More)
Tidal flow causes high temporal variability in environmental properties that impact ecosystem dynamics. Microbes such as phytoplankton are especially susceptible to tidal advection and mixing, and understanding their role in estuarine food webs and biogeochemical cycles requires information on their biomass and taxonomic composition over short time scales(More)
Two nutritional problems of the cat are reviewed. One represents a deficiency of taurine, the other vitamin A toxicity. Taurine deficiency in cats is insidious because the progressive retinal degeneration induced may go unnoticed until the damage is advanced and irreversible. Both rods and cones undergo degeneration along with the underlying tapetum(More)
Results are presented from a study of water quality dynamics in a shallow subtropical estuary, Oso Bay, Texas, which has a watershed that has undergone extensive urbanization in recent decades. High inorganic nutrient, dissolved organic matter and chlorophyll concentrations, as well as low pH (<8), were observed in a region of Oso Bay that receives(More)
It is well established that plant phenolics elicit various biological activities, with positive effects on health. Palm oil production results in large volumes of aqueous by-products containing phenolics. In the present study, we describe the effects of oil palm phenolics (OPP) on several degenerative conditions using various animal models. OPP reduced(More)
