For the sake of something real journalists call “integrity” I should point out that coffee has also been shown to have a small, yet positive (which isn’t a good thing in this case) relationship with bladder (25) cancer. However, the same study that reported these finding, also reported that this relationship could also be linked to smoking or other dietary habits.
The best water to drink is water that has been passed through a filtering process. Common and inexpensive filters are available, such as carbon filters like the ones Brita makes. The best filter is a reverse osmosis filter that puts the water through a multi-step process to remove microbes, pesticides, metals, and other toxins. This can be installed under the sink. It's a great filtering system and cheaper over the long run. Avoid water in plastic bottles, which contains phthalates, a toxic petrochemical. Mineral water or still water in glass bottles is also acceptable.
If you're getting your coffee at a coffee shop, make sure to avoid all of those fancy specialty coffees (sweetened flavored lattes, frappuccinos, etc) as they are almost ALWAYS loaded with extra sugars or artificial sweeteners. Some of those fancy coffee drinks at Starbucks or other coffee shops can have 300-400 calories in just one coffee! Definitely not good for your body or your blood sugar or insulin levels.
If you lust after those frothy frozen coffee drinks at your local coffee shop, then this mochaccino recipe is for you. This easy homemade version uses low-fat milk, cocoa powder, coffee and just a little bit of maple syrup, so it has a fraction of the calories of a traditional version. (A small mocha frappuccino at Starbucks is 270 calories!) Coffee ice cubes, made by freezing coffee in an ice cube tray, make this drink frosty and give it a big, strong coffee flavor. Recipe by Joyce Hendley for EatingWell.
When you’ve ordered a latte or a cappuccino at Starbucks, you’ve probably watched as the barista wipes down the steamer before whipping up a new cup. This is meant to fight bacteria, but you may be getting something extra in your drink that you probably don’t want. “What you don’t realize is that sanitizing solution ends up in your frothed milk! It’s not a ton, but it is there—a small amount on that wand for every frothed carafe! So avoiding lattes is a good choice if that concerns you,” Immer says. Or just prepare yours at home to make sure you’re not getting more than you bargained for. This is the healthiest coffee you can drink.
Long term consumption of coffee has also been shown to reduce, although moderately, the risk of stroke (38). Another study pointed out that drinking about five or six cups of coffee a day is associated with the greatest reduction (39) (36%) in stroke risk, and that coffee also contributes to overall reduction of cardiovascular mortality (a less scary way of saying “heart death”).
Remember, coffee from popular chains can be loaded with hidden sugars and many other artificial ingredients. Going with black coffee, or making your own, is a much healthier choice. Be sure to use filtered water and organic beans for homemade coffee. If you need a little more spice, try adding grass-fed butter, coconut oil, cinnamon, cocoa or collagen. Remember, healthier coffee doesn’t have to be boring. You can still get your morning caffeine fix – just do it in a more Paleo-friendly way!
In fact, coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars. Scientists have identified approximately 1,000 antioxidants in unprocessed coffee beans, and hundreds more develop during the roasting process. Numerous studies have cited coffee as a major — and in some cases, the primary — dietary source of antioxidants for its subjects.
Coffee is one of the most chemically treated foods in the world (global demand is high, so methods of growing it often are chemical fertilizer-pesticide-herbicide intensive). This is bad for you (since pesticide residues can end up in your cup) and really bad for the planet. High demand and the fact that it’s generally grown in poorer countries also means labor practices are a major issue. Buy organic and fair-trade if and when you can.
Other studies have tried to pinpoint exactly what in caffeine is helping to halt the onset of these diseases. A 2014 study (14) found that caffeine blocks various tau receptors (a protein that contributes to brain cell degeneration). Another study found that caffeinated coffee increased GCSF (15) - a substance greatly decreased in Alzheimer’s patients - levels in the bloodstream.
