We wanted to look at caffeine and its metabolites (the breakdown products of caffeine in the body) to see if these differed not only in people with non-genetic Parkinsonâs, but also in people who developed PD with a LRRK2 genetic mutation, which increases risk for the disease. According to the National Institute of Health in the US,…, If you have a strong family history of breast cancer but tested negative for BRCA1 and BRCA2, there’s another key gene you may want to have checked – PALB2. If you are a Slow Metabolizer then your genetic makeup indicates you process caffeine at a slower rate and, as a result, caffeine may have longer-lasting stimulant effects. Caffeine is widely consumed in foods and beverages and is also used for a variety of medical purposes. Some research indicates that genetic factors play a role in a person’s sensitivity to caffeine. “Or maybe you’re just one of those people who has a nuanced appreciation of foods that allows you to hold bitterness and pleasure in the same moment.”, Photographs by Mark Thiessen & Rebecca Hale, NGM Staff. Caffeine consumption was also significantly lesser in LRRK2 mutation carriers with Parkinsonâs (41% fewer daily milligrams of caffeine) than in mutation carriers without the disease. While genetic testing can categorize your level of caffeine sensitivity, having formal testing is generally not necessary for you to knowâat least generally speakingâwhether you're highly sensitive to caffeine. Coffee, dark chocolate and tea (especially green tea) all contain caffeine and are loaded with antioxidants and nutrients that can greatly benefit the body. Wadhawan, M. & Anand, A.C.

The link between higher caffeine levels and a reduced likelihood of having Parkinson's disease appeared stronger among those with a genetic mutation linked to the condition in a new study. Expression of adenosine receptors is regulated by a gene known as ADORA2A, and numerous studies point to variants in this gene influencing your reaction to caffeine. By knowing your genetic type, you can adjust your daily caffeine intake accordingly and better manage your overall well-being. If you are curious or concerned about how your own body reacts to caffeine, it may be beneficial to run a genetic test. Save my name, email, and website in this browser for the next time I comment. Your genes may be to blame. 4), logâphase cultures in YES were separated into the following four samples: an untreated growth control, a sample supplemented with 10 mM caffeine (Calvo et al., 2009), a sample treated with 100 ng mL â1 rapamycin, and a sample treated with both caffeine and rapamycin at the doses above. Genetics may also play a role in how your liver metabolizes caffeine. recommendations, and tools can help you build the perfect healthy lifestyle. Required fields are marked *. Although caffeine has been shown to be beneficial, not all people react to caffeine in the same way. Studies correlate its use to increased exercise performance in endurance activities, as well as its possible ergogenic effects for both intermittent and strength activities. The health benefits and risks of coffee have long been debated, with various outcomes reported (3). Learn about the chemistry of caffeine, how it causes increased alertness and focus, and how caffeine is capable of causing overdoses. Research suggests there are many potential benefits associated with caffeine. Because when it comes to caffeine, what works for one person doesn’t always work for another. In spite of the existence of a limited but expanding market for decaffeinated coffee, most people still seem to prefer the normal product with caffeine. It has also been found to play a role in anxiety—one 2008 study found that as little as 150 milligrams a day, or about as much caffeine as what’s in a Starbucks grande cappuccino—can cause disruptive anxiety in people with a certain variant of the gene. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). In other words, some people may still be adversely affected by caffeine regardless of genetics. Caffeine absorption from food and beverages does not seem to depend on age, gender, genetic background, and disease or drugs, alcohol and nicotine consumption. Moderate coffee consumption (3 to 5 cups per day) (2), for example, may help protect against several chronic diseases, including type 2 diabetes and liver disease(3,4,5).
