Bad coffee can be toxic

Bad quality coffee can have a lot of impurities in it, which can cause sickness, headache or a general bad feeling. This can happen if your coffee is made from beans that have been over ripped or otherwise ruined. Even one ruined bean can make your cup toxic. If you invest and buy high quality, specialty coffee you don’t have to worry about this.


Coffee can kill you

Yes, if you drink 80-100 cups (23 liters) in a short session. This dose is lethal and will amount in 10-13 grams of caffeine within your body. Before you reach this point, however, you’ll be vomiting most of it out since 23 liters of any liquid is a lot. Even drinking 23 liters of water can kill you.

Coffee can cause insomnia and restlessness

Again, it’s the caffeine working here. Your recommended maximum amount of caffeine is 400 milligrams, roughly the amount that you’ll get from 4 cups of coffee. If you’re caffeine-sensitive, be careful with coffee. You are probably already aware what amount and what kind of coffee suits, or doesn’t suit you. The amount of caffeine that is safe for human consumption is actually written in our DNA.

Don’t drink more than one cup a day if you’re pregnant

Studies on coffee’s effect on a fetus have been controversial, but one thing is sure: if you drink coffee when pregnant, caffeine will also reach the fetus, and your baby is highly sensitive to caffeine. So, if you’re a heavyweight coffee drinker and can’t stop drinking it while pregnant, at least reduce your coffee intake to one cup a day.


If you have high cholesterol please choose filtered coffee

Coffee beans contain cafestol and kahweol, two ingredients that appear to raise LDL cholesterol levels. Filtering the coffee traps most of the LDL, but cafestol and kahweol are found in espresso, turkish coffee, french press and scandinavian style “cooked coffee”.

(The intake of LDL from a cup of espresso is still so small, that for people with normal cholesterol levels, won’t be at risk. There are also some studies at preliminary stages of diagnosis that have found marks that cafestol and kahweol may have some beneficial anti-cancer effects, and be good for your liver.)


If you have high cholesterol or you are caffeine sensitive, pregnant or a child (or a parent of one), you should pay attention to coffee drinking.


For others, reasonable amounts (1-6 cups a day) coffee can be good for you. It can prevent serious diseases, boost your mind and muscles, and even help you with weight loss. Remember, as long as you drink toxin free, specialty coffee and brew it with care, you can and should be enjoying it knowing it’s good for you.
