Cholesterol / CVD

Egg intake and cardiovascular risk factors in adolescents: role of physical activity. The Helena study

Introduction
Cardiovascular diseases (CVDs) represent the main cause of morbi-mortality in western countries. Serum cholesterol levels have been related to cardiovascular disease (CVD). Egg intake has been indirectly related to the risk of developing CVD because of its high cholesterol content.
 
Objective
The aim of the present study was to examine the association between egg intake and CVD risk factors in adolescents, assessing the possible influence of physical activity.
 
Methods

Effect of dietary cholesterol on plasma cholesterol concentration in subjects following reduced fat, high fibre diet

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.

Dietary lipids and blood cholesterol: quantitative meta-analysis of metabolic ward studies

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.

Subjects
395 dietary experiments (median duration 1 month) among 129 groups of individuals.

A prospective study of egg consumption and risk of cardiovascular disease in men and women

Context 
Reduction in egg consumption has been widely recommended to lower blood cholesterol levels and prevent coronary heart disease (CHD). Epidemiology studies on egg consumption and risk of CHD are sparse.

Objective
To examine the association between egg consumption and risk of CHD and stroke in men and women.

Design and Setting
Two prospective cohort studies, the Health Professionals Follow-up Study (1986-1994) and the Nurses’ Health Study (1980 — 1994).

Nutritional effect of including egg yolk in the weaning diet of breast-fed and formula-fed infants: a randomized controlled trial

Background
Egg yolks can be a source of docosahexaenoic acid (DHA) and iron but are often associated with adverse consequences on plasma cholesterol.

Objective
Our goal was to investigate the effect of consumption of 4 egg yolks/wk on infant DHA status and hemoglobin, ferritin, and plasma cholesterol concentrations. Secondary outcomes included plasma iron, transferrin, and transferrin saturation.

Dietary cholesterol, eggs and coronary heart disease risk in perspective

The idea that dietary cholesterol increases risk of coronary heart disease (CHD) by turning into blood cholesterol is compelling in much the same way that fish oil improves arthritis by lubricating our joints! Dietary cholesterol, chiefly in the form of eggs, has long been outlawed as a causative agent in CHD through its association with serum cholesterol.

Consumption of one egg per day increases serum lutein and zeaxanthin concentrations in older adults without altering serum lipid and lipoprotein cholesterol concentrations

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 lipoprotein cholesterol in individuals greater than 60 y of age.

Eggs enhance the anti-inflammatory component of carbohydrate restricted diets

Carbohydrate restricted diets (CRD) have been shown to significantly decrease body fat and trunk fat and to decrease inflammatory cytokines. The purpose of this study was to evaluate the inclusion of eggs in a CRD on plasma anthropometrics, blood pressure, body composition and selected inflammatory markers in overweight/obese men (BMI = 25-37 kg/m2) aged 40-70 y undergoing a weight loss intervention.
