Whether or not to drink alcohol, especially for medicinal purposes, requires careful balancing of these benefits and risks. Mori and colleagues (2015) examined the dose-dependent effects of drinking on BP measured at regular intervals in healthy premenopausal women ages 2045. Accessed December 13, 2016. The authors, several of whom are affiliated with genetic biotechnology companies, deduced that certain gene variants predicting a persons likelihood to be a heavy drinker vs. abstainer were associated with developing CVD. Conigrave KM, Hu BF, Camargo CA, Stampfer MJ, Willett WC, Rimm EB. However, consistent heavy drinking strains those protective processes especially in your liver making them less effective. As with other alcohol-induced pathologies, mechanisms contributing to ACM include oxidative stress, apoptotic (programmed) cell death, impaired mitochondrial bioenergetics and stress, derangements in fatty acid metabolism and transport, and accelerated protein breakdown; these will be discussed in the following sections.
