I've found some info on the net and I feel quite uncertain about it. It seems to me that these "don'ts" were created to scare people and take them away from coffee lovers. But would that be a problem for a true coffee-man?
1. In the wedding night. Couples, who are expecting to have babies, don’t drink coffee during the night. From the research, caffeine found in the coffee kills sperm from 58 to 100%. It really depends on the concentration of caffeine in your coffee. Anyway, if you are expecting to have next generations, keep away from coffee.
2. Don’t drink coffee while you are smoking. A research report reviews that caffeine reacts with nicotine in cigarettes to release a toxic substance. This substance might degenerate cell metabolism or might induce cell degeneration.
3. No coffee during work. Caffeine can speed up the excretion of adrenaline. Adrenaline as a hormone will, in certain extent, elevate your blood pressure and alleviate your emotion. Therefore, drink less coffee in your work shift.
4. No coffee while you drink. The interaction of caffeine and alcohol is said to damage your body cells three times than you drink alcohol alone. Both caffeine and alcohol will stimulate your brain and increase your heart beat. It will damage your body more if you drink them together.
5. No coffee if you are calcium deficient. A medical finding reviews that you find more calcium in your urine after drinking coffee. If you take two cups of coffee, you find approximately 15 mg of calcium in your urine. Therefore, you have to be cautious if you are lack of calcium in your body. If you are committed to coffee, eat a little bit more meat and drink more milk during the day to replace your calcium content.
6. No Coffee if you have high blood pressure. A study of 1007 males and 598 females in drinking 5 cups of caffeinated coffee a day reviews that the chances of the total cholesterol has been elevated. This tends to be more chances to elevate blood pressure because of hypercholesterolemia (high cholesterol in blood). A group of 500 individuals, drinking no coffee at all, have their total cholesterol remained normal. Hypercholesterolemia will in long run bump up your blood pressure. Therefore, keep away from coffee if your blood pressure is high.
7. No coffee for the elderly. Caffeine may cause depletion of calcium out of the body; the elderly has to take less coffee to avoid early osteoporosis. Caffeine is said to be diuretic. This will make your heart work harder. That’s why the elderly has to take less coffee.
8. No coffee for kids. Caffeine activates cell metabolism. Therefore, coffee is no good for the development of kids. Research reviews that caffeine has certain relation autism. Therefore, do not let your kids drink anything with caffeine, for example, coffee.
9. Don’t drink too much coffee. Let’s take a look at the constituents of coffee beans. The beans consist of 1-3% caffeine, 10-14% fats, 5-8% protein, and some carbohydrates, inorganic salts and vitamins. Instant coffee even consists of 3-4% caffeine. There is 100-150 mg of caffeine in a cup of coffee. Ten grams of caffeine can kill an average adult. Caffeine can also get you addicted. Caffeine can increase your LDL cholesterol (Bad cholesterol) and hence your blood pressure. Therefore, a cup of coffee a day is good enough.
10. Don’t add too much sugar to your coffee. If you add more sugar to your coffee, it will drive you tired. Sugar itself will stimulate your pancreas to produce more insulin. This, in return, will lower your sugar level. That’s why you feel tired in a lowered sugar level in the body.
I'm waiting for your thoughts and opinions about these points.
