Hunger and food insecurity are important factors that may affect an individual's nutritional state and should therefore be assessed in nutrition surveillance activities. The objective of this study was to determine the level of food insecurity and hunger among HIV-positive persons accessing antiretroviral therapy in British Columbia. A cross-sectional study(More)
Plant sterols are known to have serum cholesterol lowering effects. A high dietary intake might therefore have a positive impact on health. All food items of vegetable origin contain some amount of plant sterols. The aim of this study was to analyse the plant sterol content of vegetables and fruits commonly consumed in Sweden, and to compare fresh and(More)
Demographic data, exercise habits, weight control behavior, attitudes towards body shape, eating disorder (ED) experience, and menstrual regularity among female fitness instructors were descriptively assessed. A 60-item questionnaire was sent to 295 female fitness instructors at eight fitness centers. Responders (57%) reported a mean weekly exercise load of(More)
Cardiovascular disease (CVD) is currently one of the major contributors to the global burden of disease. Combination treatments to promote a maximal reduction of the ratio between total cholesterol and high-density lipoprotein are currently the most effective way of preventing CVD. In this review, we assess the role of plant sterols and statins in CVD(More)
BACKGROUND Plant sterols are natural dietary components with serum cholesterol-lowering properties. The lowering of serum cholesterol by plant sterols is believed to be the result of an inhibition of cholesterol absorption in the small bowel, although increased bile acid excretion has also been suggested. The difference in effect of saturated and(More)
Phytosterols and omega-3 fatty acids (n-3) are natural food ingredients with potential cardiovascular benefits. Phytosterols inhibit cholesterol absorption, thereby reducing total cholesterol (TC) and LDL-cholesterol levels. Numerous clinical studies have shown that a daily intake of 1.5-2.0 g of phytosterols can result in a 10-15 % reduction in LDL levels,(More)
BACKGROUND Hydrolysis of phytosterol ester (PSTE) and phytostanol ester (PSTA) during fat digestion is not well characterised under controlled dietary conditions. AIMS The main aims of this study were therefore to quantify the PSTE and PSTA hydrolysis after gut passage and to assess whether or not PSTE and PSTA induce fat malabsorption by measuring the(More)
BACKGROUND The ketohexose D-tagatose is a new sweetener with a low energy content. This low energy content may be due to either low absorption of the D-tagatose or decreased absorption of other nutrients. OBJECTIVE The aims of this study were to measure the excretion of D-tagatose from the human small bowel, to calculate the apparent absorption of(More)
Background: There are indications that a diet rich in vegetables and/or fruit has a protective effect against se types of diseases, including cancer. Data from experimental and epidemiological studies suggest that antioxidant constituents may provide protection against environmental carcinogens. Aims: This study investigated the effect of additional(More)
Thiazolidinediones (TZDs) are insulin sensitizers widely used in the treatment of type 2 diabetes (1). Fibrates are lipid-lowering drugs that lower triglycerides (TGs) and increase HDL cholesterol (2). Individually, fibrates and TZDs generally raise HDL cholesterol. In this study, we report that certain patients treated with a combination of fibrates(More)
