A reappraisal of the impact of dairy foods and milk fat on cardiovascular disease risk
Background This review provides a reappraisal of the potential effects of dairy foods, including dairy fats, on cardiovascular disease (CVD)/coronary heart disease (CHD) risk. Commodities and foods containing saturated fats are of particular focus as current public dietary recommendations are directed toward reducing the intake of saturated fats as a means to improve the overall health of the population. A conference of scientists from different perspectives of dietary fat and health was convened in order to consider the scientific basis for these recommendations. Aims This review and summary of the conference focus on four key areas related to the biology of dairy foods and fats and their potential impact on human health: (a) the effect of dairy foods on CVD in prospective cohort studies; (b) the impact of dairy fat on plasma lipid risk factors for CVD; (c) the effects of dairy fat on non-lipid risk factors for CVD; and (d) the role of dairy products as essential contributors of micronutrients in reference food patterns for the elderly. Conclusions Despite the contribution of dairy products to the saturated fatty acid composition of the diet, and given the diversity of dairy foods of widely differing composition, there is no clear evidence that dairy food consumption is consistently associated with a higher risk of CVD. Thus, recommendations to reduce dairy food consumption irrespective of the nature of the dairy product should be made with cautionJ. Bruce German, Robert A. Gibson, Ronald M.

Trans fatty acids insulin resistance and diabetes
The possible relationship between consumption of trans fatty acids (TFAs) and risk of insulin resistance or development of diabetes mellitus type II has been considered by a number of human and animal studies over the past decade. This review evaluates the evidence, and concludes that there is limited evidence for a weak association at high TFA intakes, but very little convincing evidence that habitual exposure as part of a standard western diet has a significant contribution to risk of diabetes or insulin resistance. The possibility of increased risk for individuals with particular genotypes (such as the FABP2 Thr54 allele) is of interest, but further work would be required to provide sufficient evidence of any association

Trans fatty acids and weight gain
Increasing rates of obesity have stimulated research into possible contributing factors, including specific dietary components such as trans fatty acids (TFAs). This review considers the evidence for an association between TFA intake and weight gain. It concludes that there is limited but consistent evidence from epidemiological studies, and from a primate model, that increased TFA consumption may result in a small additional weight gain. Data from a long-term study in a primate model suggest that TFA may have a greater adipogenic effect than cis monounsaturated fatty acids; however, there are currently inadequate mechanistic data to provide a comprehensive and plausible explanation for any such metabolic differences between the types of fatty acids
Total Dietary Fiber Intake, Whole Grain Consumption, and Their Biological Effects
2-s2.0-85087971790Unlike refined grains, whole grains, which consist of entire grain, contain high micronutrients and dietary fiber in their bran and seed. In the literature many studies showed that high-fiber diets may reduce the incidence of chronic diseases such as diverticulitis, diabetes, obesity, heart diseases, and some cancer types. Once upon a time, whole grains were neglected by researchers. Following the determination that dietary fibers are present in the whole grains together with micronutrients and phytochemicals, the focus of the studies has shifted towards observational studies related to whole grains intake. Cereal fibers have proven to have stronger health effects as a result of synergistic effects with phytochemicals and micronutrients in whole grains. This chapter describes the dietary fiber-related health effects of whole grain consumption after mentioning characteristics of dietary fiber and whole grains. © 2019, Springer Nature Switzerland AG
