May 2012 - Observational studies and randomized controlled trials have examined the cardiovascular effects of fatty fish consumption and long-chain omega-3 polyunsaturated fatty acids (PUFAs) from dietary supplements. Several clinical trials have documented significant benefits of omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for cardiovascular health. Although much has been learned, some questions remain unanswered, including: what are the precise physiological effects and molecular mechanisms that account for the observed benefits for cardiovascular health; and what are the magnitudes and dose-responses of effects on specific diseases and the potential differences in various populations? National and international guidelines now give consistent recommendations for the general population: to consume at least 250 mg/day of long-chain n-3 PUFA or at least two servings of oily fish per week (1, 2).

April 2012 - Chronic, low-grade, tissue inflammation is a significant risk factor in the development of a variety of chronic diseases, such as cardiovascular disease, cancer, diabetes, osteoporosis, arthritis, Alzheimer’s disease, and auto-immune diseases. Moreover, many discomforts, such as chronic pain, memory problems, mood swings, and general muscle fatigue, can be connected in some way to an underlying inflammatory condition. An important development in nutritional science in recent years has been the discovery of anti-inflammatory properties of certain micronutrients and their potential to prevent or treat certain diseases or conditions.

March 2012 - The use of medication worldwide is growing continually, not least because of the rising age of the population. Today there are many people who take more than three different kinds of medication daily (1,2). In highly developed countries, it is particularly common for patients to be prescribed medication long-term, most frequently for the treatment of widespread chronic diseases, such as hypertension, diabetes and hypercholesterolemia. It is also a common practice in those regions to take over-the-counter medicines, including painkillers and medication for stomach ulcers (3,4). When several kinds of medication are taken concomitantly, the risks and side effects increase. In contrast to other adverse drug reactions, the inter-action between medications and micronutrients is only gradually gaining the attention of experts and the wider public. A number of medicines influence the metabolism of vitamins, minerals and trace elements in such a way that they could lead to insufficiencies or even deficiency symptoms in patients (5,6).
