Both have had bad raps...both have had good raps. Which ever one you prefer ...do you know what benefits it does provide? Caffeine is what gives coffee it's 'kick'. Caffeine stimulates the nervous system, increasing the production of noradrenaline in the brain, creating a performance-enhancing ,stimulating effect. Just what you need to beat that afternoon slump.
Coffee is high in antioxidants, thus it boosts your immune system. Caffeine promotes thermogenesis, which increases your calorie burning. It can raise your blood pressure..not so good for those with high blood pressure, but if your pressure is normal it can have a positive effect on your heart.Caffeine dilates the bronchioles of the lungs, making it easier to breathe. It also stimulates kidney function which produces more urine as well as stimulating peristalsis , getting sluggish bowels moving again. Caffeine also has a pain killing effect so is used in some medications as an analgesic. Black coffee has been shown to have a positive effect on endurance training but hasn't been proven to have the same effect on muscle strength. On the down side , it is a stimulant so shouldn't count towards your daily liquid requirement and large amounts can have a negative effect on the body. No more than 3 espressos a day and you can enjoy the health befits...guilt free!
But if your preference is tea...don't worry....you can indulge guilt free as well.Green tea is used to help resist depression. It is also said to boost your metabolism thereby aiding in weight loss. It can also help to lower your cholesterol levels. Green tea aids kidney function as well as aiding with high blood pressure and supports the intestines with probiotic effects. Green tea can also reduce by half the blood sugar spike that often accompanies meals that are rich in carbohydrates.
So, all in all, both tea and coffee have a lot of health benefits going for them...so enjoy whichever one you prefer...just remember...everything in moderation.
