For coffee drinkers, nothing beats the aroma and taste of a freshly brewed cuppa. Considering so many of us start the day with a cup or two, here are a few things to know about whether to imbibe or abstain?
It’s full of antioxidants and nutrients.
Coffee is a pretty complex drink, as it’s made up of hundred of compounds, from caffeine to vitamins and minerals. A single cup of coffee contains 11 percent of your daily recommended riboflavin (vitamin B2), and also has small amounts of pantothenic acid (vitamin B5), magnesium, potassium and niacin.
Coffee also contains powerful antioxidants called quinines that become more potent after the beans are roasted. And the antibacterial compound trigonelline in coffee has been shown to prevent cavities in black coffee drinkers.
Coffee’s caffeine may delay the onset of Alzheimer’s and Parkinson’s disease.
Alzheimer's research studies have shown that drinking 3-5 cups of coffee a day in midlife can slow down the start of the illness by up to 65 percent later in life. This is perhaps because caffeine blocks inflammation in the brain and suppresses the rise of amyloid plaques that are strongly linked to Alzheimer’s disease. Caffeine also slows the progression of Parkinson’s disease, and eases tremors by blocking certain receptors in the brain that cause symptoms.
Coffee protects us against type 2 diabetes.
Drinking more than four cups of coffee each day can help keep type 2 diabetes at bay, according to scientists at Harvard. Seems the antioxidants and minerals in coffee, including magnesium and chromium, help your body use insulin which controls blood sugar levels.
Skip it if: You’re pregnant.
Caffeine is the culprit here—it can go through the placenta and reach the fetus, and can keep you and your baby awake (it has also been linked to higher incidences of miscarriage). For pregnant women it may be better to reduce coffee consumption to one or two cups a day.
Skip it if: You have trouble controlling high blood pressure.
If you’re not a coffee drinker and you start, the first week or so of drinking it can raise your blood pressure significantly, though after a few weeks those readings usually go down. If you have a hard time controlling your hypertension, limit coffee intake or switch to decaf coffee.
Skip it if: Your decaffeinated coffee is processed with solvents.
There are a few ways to remove caffeine from coffee beans, and a common process uses the chemical solvent methylene chloride. Although the FDA has approved its use in decaffeinating coffee, this solvent’s side effects in higher exposures include headaches, dizziness and other central nervous system troubles. Instead, be sure your decaf coffee is processed by the Swiss water process, a chemical-free method that uses green coffee bean water and filters to remove nearly 100 percent of the caffeine.
