6 Reasons to drink...Coffee
Often people think of coffee just as a vehicle for caffeine," writes Dr. Rob van Dam of the Harvard School of Public Health. "But it's actually a very complex beverage," containing hundreds of different chemical compounds.
So why should we ALL drink coffee?
1. Coffee... Loaded With Nutrients and Antioxidants
Coffee isn't just black water. Many of the nutrients in the coffee beans do make it into the final drink, which actually contains a decent amount of vitamins and minerals.
A cup of coffee contains:6% of the RDA for Pantothenic Acid (Vitamin B5).11% of the RDA for Riboflavin (Vitamin B2).2% of the RDA for Niacin (B3) and Thiamine (B1).3% of the RDA for Potassium and Manganese.Collectively this may not seem like much, but if you drink several cups of coffee per day then this quickly adds up. But there is more... coffee also contains a massive amount of antioxidants. In fact, coffee is one of the biggest source of antioxidants in the western diet, outranking both fruits and vegetables combined.
2. Coffee... Can Make You Smarter
The active ingredient in coffee is caffeine, which is a stimulant and the most commonly consumed psychoactive substance in the world. Caffeine's primary mechanism in the brain is blocking the effects of an inhibitory neurotransmitter called adenosine. By blocking the inhibitory effects of adenosine, caffeine actually increases neuronal firing in the brain and the release of other neurotransmitters like dopamine and norepinephrine. It has a net stimulant effect. A study by Ruxton (2008), examined the effects of caffeine on the brain, demonstrating that caffeine can improve mood, reaction time, memory, vigilance and general cognitive function.Harris Lieberman, a research psychologist for the military, outlined; Reaction time, vigilance, attention, logical reasoning — most of the complex functions you associate with intelligence – are improved by caffeine.
3. Coffee... Can Help You Burn Fat and Improves Physical Performance
Caffeine, partly due to its stimulant effect on the central nervous system, both raises metabolism and increases the oxidation of fatty acids. Caffeine can also improve athletic performance by several mechanisms, including the mobilizing of fatty acids from the fat tissues. In two separate meta-analyses, caffeine was found to increase exercise performance by 11-12% on average. Researchers at Coventry University in England discovered that the magic performance-enhancing ratio appears to be 6 milligrams of caffeine for every 2.2 pounds (1kg) of body weight.
4. Coffee... May Lower Your Risk of Type II Diabetes
In observational studies, coffee has been repeatedly associated with a lower risk of Type II diabetes. The reduction in risk ranges from 23% to 67%. A massive review article looked at 18 studies with a total of 457,922 participants. Each additional cup of coffee per day lowered the risk of diabetes by 7%. The more coffee people drank, the lower their risk.
5. Coffee... May Lower Your Risk of Alzheimer's and Parkinson's
Not only can coffee make you smarter in the short term, it may also protect your brain in old age. Alzheimer's disease is the most common neurodegenerative disorder in the world and a leading cause of dementia. In prospective studies, coffee drinkers have up to a 60% lower risk of Alzheimer's and Dementia.
Parkinson's is the second most common neurodegenerative disorder, characterized by death of dopamine-generating neurons in the brain. Coffee may lower the risk of Parkinson's by 32-60%.Why? Chuanhai Cao, a neuroscientist at the University of South Flordia, has a theory: caffeine "inhibits production of beta-amyloid," a protein that has been shown to build up in the brain of people with Alzheimer's disease. The older you get, the harder it is to metabolize — or use up — all that excess protein, which causes a log jam in your brain. The stimulant boost from java ensures "your system only metabolizes all of the available protein," says Cao.
6. Coffee... May be Good For Your Liver
Numerous studies have suggested that caffeine helps the liver regulate itself .The liver is vulnerable to modern insults such as excess consumption of alcohol and fructose. Cirrhosis occurs when the liver tissue has been largely replaced by scar tissue. Multiple studies have shown that coffee can lower the risk of cirrhosis by as much as 80%, the strongest effect for those who drank 4 or more cups per day. Coffee may also lower the risk of liver cancer by around 40%
