Obese individuals typically present raised levels of the blood vessel-constricting protein endothelin ET 1, which has a range of serious negative effects on their cardiovascular health. A new study has found that normal ET 1 levels can be restored with a three-month daily dose of 500 mg vitamin C.
Elevated levels of the blood vessel-constricting protein endothelin ET 1 are found in the blood vessels of obese people. This restriction of blood flow increases the individual’s risk of vascular disease. ET 1 increases pulmonary hypertension and has many other negative effects on cardiovascular health, such as platelet activation, stimulated production of free radicals, pro-inflammatory actions, and mitogenesis (1).
ET 1 activity can usually be reduced by taking regular exercise. However, this can be difficult or impractical for some severely obese people and indeed it is reported that more than half of obese individuals in the USA do not take regular exercise.
A new study by Dr Dow of the University of Colorado Boulder, CO, involving a cohort of 35 sedentary, obese adults has found that supplementation with a daily intervention of 500 mg vitamin C (in controlled release form) over three months helps to restore normal ET 1 levels. It is therefore suggested that daily supplementation with a high dose of vitamin C would be of benefit to obese individuals who are unable to undertake regular exercise.

Nutritional genomics is a science that studies the relationship between the human genome, nutrition and health. It can be divided into ‘nutrigenomics’, which investigates the effect of nutrients on health through altering gene expression, and ‘nutrigenetics’, analyzing genetic variations (polymor-phisms) among individuals with respect to the interaction between nutrients and disease. It is becoming increasingly evident that the risk for developing degenerative diseases increases with more DNA damage, which in turn is dependent on micronutrient status.
