Nutrient profiling of foods, described as the science of ranking foods based on their nutrient content, is fast becoming the basis for regulating nutrition labels, health claims, and marketing and advertising to children. A number of nutrient profile models have now been developed by research scientists, regulatory agencies, and by the food industry. Whereas some of these models have focused on nutrients to limit, others have emphasized nutrients known to be beneficial to health, or some combination of both. Although nutrient profile models are often tailored to specific goals, the development process ought to follow the same science-driven rules. These include the selection of index nutrients and reference amounts, the development of an appropriate algorithm for calculating nutrient density, and the validation of the chosen nutrient profile model against healthy diets. It is extremely important that nutrient profiles be validated rather than merely compared to prevailing public opinion. Regulatory agencies should act only when they are satisfied that the scientific process has been followed, that the algorithms are transparent, and that the profile model has been validated with respect to objective measures of a healthy diet.

    • "Undoubtedly, telomere maintenance and telomerase activation are highly regulated and largely genetically determined. Of several factors that modulate telomere length and telomerase activity, ROS, hormones, growth factors , smoking status, diet, socioeconomic status, stress level, and lifestyle influence telomere dynamics [4] [5] [6]. The sex hormones directly increase telomerase reverse transcriptase (TERT) transcription and telomerase activity in human cells [7] [8]. "

    • "In this respect, the contribution to energy and nutrient intakes of major food groups can be established. This assessment allows for identifying the relative nutrient-percalorie cost so that foods that are affordable, appealing, as well as nutrient rich are in dietary guidelines [8]. A nutrient profiling analysis of the U.S. diet shows that milk and milk products are foods of low energy with substantial micronutrient density and appreciable affordability [7]. "

    ABSTRACT: The risk of fragility fractures exponentially increases with aging. Reduced mass and strength of both bone in osteoporosis and skeletal muscle in sarcopenia play a key role in the age-related incidence of fragility fractures. Undernutrition is often observed in the elderly, particularly in those subjects experiencing osteoporotic fractures, more likely as a cause than a consequence. Calcium (Ca), inorganic phosphate (Pi), vitamin D, and protein are nutrients that impact bone and skeletal muscle integrity. Deficiency in the supply of these nutrients increases with aging. Dairy foods are rich in Ca, Pi, and proteins and in many countries are fortified with vitamin D. Dairy foods are important souces of these nutrients and go a long way to meeting the recommendations, which increase with aging. This review emphaszes the interactions between these 4 nutrients, which, along with physical activity, act through cellular and physiological pathways favoring the maintenance of both bone and skeletal muscle structure and function.

    • "Milk plays a fundamental role in modern western diets. It is an easily accessible matrix rich in a wide variety of essential nutrients such as minerals, vitamins and easily digestible proteins with balanced amino acid profiles, which are important in supporting most body functions (Drewnowski and Fulgoni, 2008; Silanikove et al., 2010). High-quality raw milk constituents are required to obtain high yields and good-quality dairy products such as yogurt and cheese (Oliveira et al., 2002; Leitner et al., 2008). "

    ABSTRACT: The aim of this work was to study the effects of mastitis induced by intramammary lipopolysaccharide (LPS) challenge on milk oxidative stability, as well as to understand the underlying biochemical processes that cause such changes. LPS challenge was associated with nitric oxide burst from the surrounding mammary epithelial cells and consequently induced nitrosative stress that was induced by the formation of NO2• from nitrite by lactoperoxidase. This response was associated with an ∼3-fold increased formation of hazardous compounds: nitrotyrosines, carbonyls and lipid peroxides. We sustained the involvement of xanthine oxidase as a major source of hydrogen peroxide. In consistent with previous findings, catalase has been shown to play a major role in modulating the nitrosative stress by oxidizing nitrite to nitrate. The current hygienic quality criteria cannot detect mixing of low-quality milk, such as milk with high somatic cells, and nitrite with high-quality milk. Thus, development of an improved quality control methodology may be important for the production of high-quality milk.
