Final answer:
Moderate drinking is associated with a reduction in coronary heart disease, providing some protective benefits against heart disease. Excessive drinking, on the other hand, carries significant risks such as increased risk of breast cancer, liver disease, high blood pressure, and other health issues.
Step-by-step explanation:
One of the effects of moderate drinking is a reduction in coronary heart disease. This effect is considered a positive aspect of alcohol consumption, and many studies suggest that individuals who consume alcohol in moderation may experience some protective benefits against heart disease compared to those who abstain. Moderate consumption of alcohol can lead to pleasurable social interaction and a pleasant state of mind, and statistically, those who drink a moderate amount of alcohol regularly may have a longer lifespan than those who do not drink at all.
However, it is essential to consider that the benefits of moderate alcohol consumption must be weighed against the potential risks, such as an increased risk of breast cancer, liver disease, and the impact on the excretory system with heavy and excessive drinking. In fact, drinking more than two alcoholic beverages a day is associated with an increased risk of high blood pressure, which can lead to serious kidney disorders.
