    Alcohol misuse in patients attending a defence force general medical clinic
    (Medpharm Publications, 2003) Bekker, D.; Van Velden, D. P.
    Alcohol misuse may come to be recognized as one of the most significant public health concerns facing South Africa over the next few years. This is a direct result of alcohol's impact on the health services, the economy, and the South African society as a whole. Alcohol misuse is common world-wide and in South Africa there is an estimated prevalence of 10% of alcohol dependence in the adult population. However, relatively few studies have been published on drinking patterns in South Africa. With regards to adults, epidemiological studies in recent years have also focussed almost entirely on the black and coloured population while they are not the only groups who have high levels of risky drinking.

    Die rol van matige wynverbruik tydens maaltye in die voorkoming van hartsiektes
    (Medpharm Publications, 2000) Van Velden, D. P.; Mansvelt, E. P. G.
    pidemiological evidence consistently link moderate red wine consumption with reduced incidence of cardiovascular disease. lt has been found that there is a much lower mortality from cardiovascular disease, mainly coronary artery disease (CAD),in the countries borderingthe Mediterranean compared with that in Northern Europe. This was coined "The French Paradox", describing the phenomenon that the French have a low incidence of CAD despite the hct that they follow a diet rich in saturated fat. lt is well known that the French regularly consume red wine with their meals. Platelet aggregability plays an important role in the pathogenesis of CAD.Various phytochemicals in red wine may reduce platelet rggregation, serum lipid peroxidation and hence thrombosis. We investigated the effects of regular moderate red wine consumption on platelet aggregability ex vivo and on the serum lipid profile and antioxidant status.We conclude

    Sylicylic acid in wine as a therapeutic agent in cardiovascular disease
    (Medpharm Publications, 2000) Van Velden, D. P.; Hundt, H. K. L.
    Epidemiological evidence consistently links moderate wine consumption with reduced mortality, mostly due to reduced incidence of cardiovascular disease. Recent scientific reports indicating that a diet rich in fruit and vegetables, together with moderate amounts of alcohol, but more specific red wine in moderation, is protective against various degenerative diseases, created a renewed interest in the consumption of grapes and wine as part of a healthy diet and lifestyle.

    Wine and health : research in action
    (Academy of Science of South Africa, 2001) Armstrong, G. O.; Lambrechts, M. G.; Mansvelt, E. P. G.; Van Velden, D. P.; Pretorius, I. S.
    Is it possible that wine may indeed be the world's oldest medicine? Until the 18th century, wine played an integral role in medical practice. Not only was it safer to drink than most available water but its alcohol, antioxidant and acid content inhibited the growth of many spoilage and pathogenic organisms. The paradigm shifted in the second half of the 20th century, when alcohol consumption, including wine drinking, had become the target of health campaigners who, with some success, demanded warning labels on wine bottles. Substantial medical evidence, summarized in this article, was accumulated during the 1990s and indicated that the moderate consumption of especially red wine can reduce the incidence of coronary heart disease. Today it is perceived, and generally accepted, that moderate wine drinking can be socially beneficial, and can also be effective in the management of stress and reducing coronary heart disease. The prudent wine drinkers, however, continue to monitor their drinking habits so as to ensure that the benefits exceed the risks.
