Objective To determine the quantitative importance of dietary fatty acids and dietary cholesterol to blood concentrations of total, low density lipoprotein and high density lipoprotein cholesterol. Design Meta-analysis of metabolic ward studies of solid food diets in healthy volunteers...

Background: Dietary protein intake may help to manage blood pressure (BP) and prevent complications associated with elevated BP. Objective: The objective of this study was to determine whether 4 wk of increased protein intake (∼25% compared with ∼15% of energy intake that isoenergetically...

Purpose Advice about the role of eggs in the diet has changed several times over the decades. The aim of the current paper is to evaluate published evidence reporting associations between egg consumption, egg nutrients and health. Design/methodology/approach The scientific literature was...

Objective To estimate choline intakes of US subpopulations including children, men, women and pregnant women. Background Choline is an essential nutrient which plays critical roles in brain development and homocysteine metabolism. Choline is widely distributed in foods; good sources...

Quantitative relations between dietary fat and cholesterol and plasma lipid concentrations have been the subject of much study and controversy during the past 40 years. Previous meta-analyses have focused on the most tightly controlled, highest-quality experiments. To test whether the...

Highlights Brain orexin/hypocretin cells are stimulated by dietary amino acids (AAs) AA sensing involves K-ATP channels and system-A transporters Nonessential AAs stimulate orexin/hypocretin cells more than essential AAs AA presence prevents glucose from blocking orexin/hypocretin cells...

Objective Dietary guidelines for the prevention of coronary heart disease (CHD) have restricted the intake of foods rich in dietary cholesterol, on the grounds that the dietary cholesterol will increase blood cholesterol. In the case of shellfish, this recommendation may limit the intake...

Lutein and zeaxanthin accumulate in the macular pigment of the retina, and are associated with a reduced incidence of macular degeneration. The objective of the study was to investigate the effect of consuming 1 egg/d for 5-wk on the serum concentrations of lutein, zeaxanthin, lipids and...

One hundred and sixty eight subjects participated in a randomised crossover study to determine whether halving or doubling the present dietary cholesterol intake from eggs had any influence on blood cholesterol concentration in people following current dietary recommendations. During the...

Abstract Bed rest studies revealing a “horrifying” loss of muscle mass in older people after just a few days of inactivity should serve as a wake-up call for industry to put tackling sarcopenia higher up the priority list, scientists have argued. Speaking at the IFT show earlier this month...
