Once considered to be harmful, coffee research has exploded in recent years. New studies show improvements in a number of different areas of health and even suggest how much to consume for maximum benefit.
COFFEE PROTECTS YOUR HEART
This is contrary to older thought, but Life Extension(1) discusses studies that show positive effects to your heart, blood vessels, and brain. To protect your heart, coffee works on the cells that form a lining in your heart and blood vessels–the endothelium. Coffee relaxes the vessels and has an anti-inflammatory effect. There is a 11% reduction of heart disease with 1.5 cups a day and a 15% reduction with 3.5 cups a day.
COFFEE REDUCES FAT AND DIABETES
I always question how adding to your consumption can reduce fat, but there are now many studies behind this. A compound in coffee, chlorogenic acid, has anti-oxidant and anti-inflammatory effects that lowers your blood sugar and abdominal fat. This activates the immune system helping to prevent cancer as well. Your diabetic risk is reduced by 8, 15, 21, 25, 29, and 33% for consumption of 1 to 6 cups a day.
COFFEE PREVENTS SOME CANCERS
Liver and kidney cancers are the most improved even if you already have hepatitis. Many Americans eat a fatty diet and like their alcohol which damages the liver. Coffee’s anti-oxidant enzymes deactivate cancer enzymes. It helps destroy renal cancer cells in your kidneys. Drinking 2-3, 4-5, 6-7, or 8 cups a day results in liver cancer reduction of 34, 56, 62, and 68%.
COFFEE PROTECTS YOUR BRAIN
Age related cognitive decline leading to dementia is a concern for all of us. Caffeinated coffee elevates plasma levels which improves memory and may promote new brain cells. Two of the most common disorders of aging, Alzheimer’s and Parkinson’s, can be reduced. Consuming 3 cups a day reduces your chance of Parkinson’s by 28%.
Life Extension(1) notes coffee drinkers are at a lower risk of dying from all causes with caffeinated coffee having a slightly stronger effect. I’ve been a fan of green tea health benefits, but with this new research, it looks like coffee in the morning and green tea the rest of the day.
