Erythrocyte membrane fatty acid composition of smokers and non-smokers: effects of vitamin E supplementation

Article Abstract:

The effect of vitamin E supplementation on vitamin E and polyunsaturated fatty acid (PUFA) concentrations in red blood cells (RBC) among smokers was investigated. Thirty male smokers and 30 male nonsmokers were recruited in a study to analyze the effects of vitamin E, RBC PUFA composition and smoking on the susceptibility of the cells to lipid peroxidation. Results showed that the levels of essential fatty acids (EFA) in RBC were higher in nonsmokers than in smokers. Vitamin E supplementation increased the RBC EFA concentrations in smokers.

The effect of whisky and wine consumption on total phenol content and antioxidant capacity of plasma from healthy volunteers

Article Abstract:

A new study investigates whether consumption of 100 ml of whisky or red wine by healthy male volunteers increases antioxidant capacity and plasma total phenol content. Results show that antioxidant capacity and plasma total phenol content both increased within 30 min of consumption of wine and whisky. The outcome is compatible with the proposal that the risk of coronary heart disease is decreased with moderate alcohol consumption.

Selenium status of a group of Scottish adults

Article Abstract:

Selenium plays a role in the body's anti-oxidant defense system and may aid in preventing cardiovascular disease. A study on the selenium status of Scottish adults suggested that as much as 90% of the subjects have selenium intake lower than the recommended values. A further study is warranted as the low levels of plasma selenium reported does not correspond to the normal RBC selenium levels obtained.
