4 truths about caffeine, share after reading

1. Women metabolize caffeine more slowly than men (that is, caffeine stays in the body longer in women)

Under normal circumstances, the half-life (metabolic cycle) of caffeine is about 6 hours on average. What does this mean? For example, if you drink a cup of coffee containing 100 mg of caffeine at 12 noon, by 6 pm, your body will have excreted half of the caffeine concentration, which is 50 mg. By midnight, the caffeine content in your body will drop to 25 mg, then 12.5 mg, and so on, until you completely eliminate the caffeine in your body. So, do different genders have different metabolic cycles? Studies have shown that after drinking the same caffeine concentration, women retain an average of 3-4 times the caffeine concentration in their bodies after 24 hours than men. Why is this? There are many factors that affect the metabolic rate of caffeine. Factors such as age, weight, and whether or not you smoke can have an impact. So it is likely that caffeine has a greater (longer) stimulating effect on women than men.

2. Caffeine only accounts for about 10% of the total bitterness of coffee

When we think of coffee, most people immediately think of caffeine, and since caffeine is an alkaloid with a strong bitter taste , it's common to think that caffeine is responsible for coffee's bitterness. But the truth is, according to statistics, caffeine only accounts for 10-15% of coffee's total bitterness. It turns out that most of coffee's bitterness comes from the formation of secondary compounds produced during the roasting process, not from caffeine itself.

3. Caffeine Increases Fat Burning During Exercise (Fitness)

Go to the corner cafe for a cup before working out? Researchers say that drinking a cup of coffee before exercising may stimulate cells to release free fatty acids into the blood, thereby helping you "burn fat." Once released, these fatty acids can be used as abundant "fuel." In addition, caffeine can increase your physical activity, making you more energetic and efficient during exercise.

4. Caffeine causes the brain to release dopamine (making your mind more active)

For millions of people, the day starts with a hot cup of coffee. Some would even say that without it, their ability to interact with others would be limited. David Letterman even once said, "Without coffee, I have no personality at all." Does this make sense? According to researchers, drinking coffee may promote the release of dopamine in the brain, which can have a positive impact on human cognitive abilities. Unlike cocaine or amphetamines, the caffeine in coffee acts on the prefrontal cortex, which is involved in cognitive behavior, complex planning, decision-making, and overall personality expression. So drinking coffee can actually help people think better .
