Effects of tea on myocardial infarction

In addition to the cardiac activities discussed, tea polyphenols are believed to have antiplatelet, antithrombotic and anti-inflammatory properties, and animal studies suggest that they may also improve vascular function. This suggests that ingestion of tea could minimise the risk of developing CHD and of having an MI.26 The association between tea consumption and MI has been the subject of a number of epidemiological studies. Both inverse and converse relationships have been found in studies...

Figure 2.10 The structures of (a) docosahexaenoic acid (DHA) and (b) eicosapen-taenoic acid (EPA). Figure 2.10 The structures of (a) docosahexaenoic acid (DHA) and (b) eicosapen-taenoic acid (EPA). Docosahexaenoic acid (DHA) (Figure 2.10) is one of the major components of grey matter in the brain, and is important in the retina, testes, and present at high levels in fish oil. The major source is marine algae, consequently the largest commercial source is fish feeding off the algae. Many of the...

N3 and n6 Essential fatty acids

A large amount of research has been carried out into the effects of the so-called 'Mediterranian diet', centred mainly around the fatty acid composition of the diet. The concomitant consumption of a wide range of other constituents may, however, be part of the overall benefits. A high dietary intake of saturated fat is thought to increase cholesterol levels and increase the risk of atherosclerosis. n-3 and n-6 PUFAs are believed to be beneficial in preventing or reversing high cholesterol...

Octacosanolpolicosanol

Policosanol has been claimed to be as effective as the currently available lipid-lowering drugs, such as the statins, in lowering lower plasma cholesterol.98 Policosanol was first developed in Cuba and used as a major cardiac medicine in the Caribbean region.99 It has been postulated that cholesterol levels in people consuming mainly vegetarian diets is lower than in those eating commercially prepared foods, possibly due to the presence of natural alkanols such as octacosanol. To date,...

Cetylated fatty acids

Another group of fatty acids currently undergoing evaluation of their beneficial effects in joint disease are the cetylated, monounsaturated fatty acids (CFA) such as cetyl myristoleate (CMO), which, although their mechanism of action is uncertain, may act to reduce inflammation, possibly due to the inhibition of 5-lipooxygenase.52 One study evaluated the benefits of the administration of an oral preparation of a blend of CFA in 64 patients with chronic knee OA.52 Patients were evaluated after...

Pycnogenol

Pine bark has been used traditionally to treat inflammatory diseases, which gives some credence to the use of the pine bark extract Pycnogenol. A range of cardiovascular effects have also been reported, including vasorelaxant effects, inhibition of angiotensin-converting enzyme (ACE) and increase in the microcirculation by increasing capillary resistance.107 One clinical trial using Pycnogenol (150 mg day for six weeks) increased the plasma polyphenol levels and antioxidant activity in subjects...
