Fresh produce and nuts and seeds pack a lot of zinc, beta-carotene, vitamins A, C, and E, and other nutrients you need for a healthy body. Plant-based foods also fill you up with fiber, which helps lower your body fat percentage, which can strengthen your immune response. Once in the system, alcohol is broken down into a harmful chemical that damages the DNA. Continual drinking makes it difficult for the body to repair or counter this damage.
- Alcohol-induced changes in tight junctions cause increased intestinal leaks that lead to translocation of bacteria-derived products such as lipopolysaccharide (LPS).
- This defect was rescued when cultures were treated with the Rho kinase inhibitor, Y27632 indicative that ethanol reduced efferocytosis through the induction of Rho kinase activity in a dose-dependent manner (Boe, Richens et al. 2010).
- The antibodies can recognize and interact with antigens, and each B-cell produces antibodies that recognize only one specific antigen.
- Nicotine from cigarettes, chewing tobacco, or any other source can weaken your body’s ability to fight germs.
- However, alcohol can also weaken the immune system, cause serious health conditions and make the body more vulnerable to infections and viruses.
Alcohol can hinder the body’s ability to recover from tissue injury and heal infections. If a person regularly drinks alcohol, their injuries, cuts, and surgical site wounds may heal slower than someone who avoids alcohol. They are also more vulnerable to developing cellulitis and surgical site infections. The respiratory tract contains cilia, which are microscopic projections that move the mucus toward the throat. This movement prevents bacteria, particles, and fluid from entering the lungs.
Who might have alcohol intolerance?
Other chemicals in e-liquids seem to suppress your immune response, especially when you inhale them through vaping. In the summer, just 5-15 minutes of rays on your hands, face, and arms 2-3 times a week usually is enough. That may be a problem, say Kathy Jung and Joe Wang, experts at the National Institute on Alcohol Abuse and Alcoholism (NIAAA). In addition to the well-known risks of drinking too much, they noted that chronic drinking can do serious damage to your immune system over time. Not only that, but their review of literature suggests drinking too much during a pandemic may put you at greater risk of infection. When the body detects a threat—such as pathogens (e.g., bacteria, viruses), chemical irritants, or damaged tissues from injury—it initiates an inflammatory response to eliminate the threat and promote healing.
The adaptive immune response can be distinguished from innate immunity by the capability of generating immunological memory, or protective immunity against recurring disease caused by the same pathogen (Janeway 2008). Clinicians have long observed an association between excessive alcohol consumption and adverse immune-related health effects such as susceptibility to pneumonia. Acute and chronic alcohol exposure can interfere with various aspects of the adaptive immune response, including the antigen presentation required to activate T- and B-cells, the activity of CD4+ and CD8+ T-cells, and the activity of B-cells. This alcohol-mediated dendritic cell dysfunction prevents the organism from generating virus-specific adaptive immune responses involving CD4+ and CD8+ lymphocytes, which may contribute to the acquisition and persistence of hepatitis C infection (Siu et al. 2009).

The dendritic cell (DC), which plays a critical role in T cell activation and initiation of adaptive immune responses, is another innate immune cell affected by ethanol. DCs uptake antigens in peripheral tissues which leads to their maturation, and then travel to draining lymph nodes where they present them does alcohol suppress immune system to T cells (Janeway 2008). Similarly, consumption of 10% (w/v) ethanol in tap water ad libitum for 2 days in mice resulted in decreased bone marrow DC generation, decreased expression of CD80 and CD86, impaired induction of T cell proliferation, and a decrease in IL-12 production (Lau, Abe et al. 2006).
