Besides coffee and tea leaves, kola nuts and cocoa beans are also included among the most common source of caffeine. Caffeine content varies from food to food depending on the type and serving size of food or beverage and how it’s prepared. Even decaffeinated coffee isn’t completely free of caffeine. Here are most of the common myths about caffeine.
Myth 1. Caffeine is likely to cause Insomnia
Caffeine has a relatively short half-life, of about five to seven hours, on average, to eliminate half of it from the body. Our body not only absorbs caffeine quickly but also gets rid of it quickly too. For most people, a cup of coffee in the morning won’t interfere with their sleep at night.
Consuming caffeine later in the day can interfere with sleep, if taken 2-3 hours before going to sleep, but not to that extent, that it results in insomnia. Sensitivity may depend on your rate of metabolism and the amount of caffeine you consume regularly. People who are more sensitive may experience caffeine side effects of gastrointestinal upset and even insomnia.
Myth 2. Caffeine Increases the Risk of Osteoporosis and Heart Disease
Having about 300 milligrams of caffeine or 3 cups of coffee daily, cause no harm in healthy adults but people with high blood pressure or older people, need to keep a check on their caffeine intake. Excess intake of coffee can increase calcium and magnesium loss in urine, but it won’t increase the risk of bone loss if you are taking adequate calcium.
Slight rise in heart rate and blood pressure is common in people who are sensitive to caffeine and it doesn’t increase the risk of any cardiovascular disease.
Myth 3. Caffeine has a dehydrating effect
Caffeine is a mild diuretic and drinking caffeine drinks in moderation doesn’t cause dehydration. The fluid in caffeinated drinks tends to offset the effects of fluid loss when you urinate.
Myth 4. Caffeine helps you Sober Up
Studies have shown that people usually think that caffeine helps them sober up but it isn’t so. People who drink caffeine along with alcohol still have impaired reaction time and judgement. Drinking coffee doesn’t help sober up.
Myth 5. Caffeine has no Health Benefits
Caffeine is known for various potential health benefits. It reduces the risk of liver disease, Type 2 diabetes and dementia. Despite its benefits, caffeine should always be taken in moderate amount to avoid its potential risks.
