In practical terms, brewed roasted coffee generally provides more caffeine per serving than brewed green coffee.

Yes, caffeine can cause your heart to flutter, a sensation often referred to as palpitations. This is due to caffeine's stimulating effects on the central nervous system, which can increase heart rate and lead to irregular heartbeats in some individuals. People who are sensitive to caffeine or consume it in large amounts may be more likely to experience these effects. If palpitations are frequent or concerning, it's advisable to consult a healthcare professional.

Caffeine can stimulate gastric secretions rather than decrease them. It increases the production of gastric acid, which may lead to enhanced digestive processes. However, excessive caffeine intake could potentially lead to digestive issues, such as acid reflux or gastrointestinal discomfort, due to the increased acidity. Overall, caffeine tends to promote rather than inhibit gastric secretions.

To calm down after consuming too much caffeine, try to hydrate by drinking water, as it can help flush out excess caffeine. Engage in deep breathing exercises or mindfulness techniques to reduce anxiety and promote relaxation. Additionally, consider going for a light walk or practicing gentle stretching to release pent-up energy. Lastly, avoid consuming more caffeine and opt for calming herbal teas like chamomile or peppermint.

Caffeinated drinks can sometimes appear to fizz more than non-caffeinated ones due to the presence of carbon dioxide and the way carbonation interacts with caffeine. However, the fizzing primarily depends on the level of carbonation and the drink's composition rather than caffeine content itself. Generally, drinks with higher carbonation levels will fizz more, regardless of whether they contain caffeine.

No, spironolactone does not contain caffeine. It is a medication primarily used as a diuretic and for conditions like heart failure, high blood pressure, and hormonal imbalances. Caffeine is a stimulant found in various beverages and foods, but it is not an ingredient in spironolactone. Always consult a healthcare professional for specific medication inquiries.

Caffeine can have both positive and negative effects, depending on individual tolerance and consumption levels. Moderate intake is associated with benefits like improved alertness, enhanced cognitive performance, and even a lower risk of certain diseases. However, excessive consumption can lead to negative outcomes such as anxiety, insomnia, and increased heart rate. Ultimately, it's important to consume caffeine in moderation and be mindful of one's own health conditions.

Caffeine-free sodas can contain aspartame, but it varies by brand and specific product. Aspartame is an artificial sweetener used in many diet sodas, including some caffeine-free varieties, to provide sweetness without added calories.
