A study published in Molecular Nutrition & Food Research, was performed in order to show whether a dark roast coffee beverage had stronger antioxidant effects on humans than a light roast.

“Intake of the dark roast CB most effectively improved the antioxidant status of erythrocytes: superoxide dismutase and glutathione peroxidase activity decreased by 5.8 and 15%, respectively, whereas tocopherol and total glutathione concentrations increased by 41 and 14%, respectively. Furthermore, administration of the NMP-rich CB led to a significant body weight reduction in pre-obese subjects, whereas the CGA-rich CB did not.”

In other words, dark roast coffee is more effective than light roast coffee in reducing body weight, and in restoring red blood cell vitamin E and glutathione concentrations in healthy volunteers.

Many researchers say glutathione is probably the most important substance we require to stay healthy. Many go as far to say it’s the secret to prevent aging. Present in every cell of our body, glutathione levels just might be one of the best biochemical markers there is; the higher your glutathione levels are the healthier you will be. Glutathione deficiency is found in almost all patients with extreme illnesses, e.g., cancer, heart disease, Parkinson’s disease, Alzheimer’s, arthritis, liver disease, diabetes and more. The anti-aging secret

In his book, “The Most Effective Ways to Live Longer”, Johnny Bowden identifies what he calls “the four horsemen of aging,” which are thought to be dangerous processes that age our bodies and are triggered by the foods we eat and the lifestyles we lead. Conquer these four horsemen, Bowden contends, and you can slow down the aging process.

1. Free radicals: Free radicals are chemically unstable molecules that attack your cells and damage your DNA. You can limit your exposure to them by avoiding cigarettes, trans fats, charred meats, and other sources.

Organic fruits and vegetables will also limit your exposure to pesticides and herbicides, which contain the harmful molecules.

2. Inflammation: Inflammation is a major player in many diseases of aging, including cancer, diabetes, heart disease, and Alzheimer’s. One way to avoid it is to follow a Mediterranean-style diet.

Other great anti-inflammatory foods include turmeric, dark chocolate, and the anti-aging chemical resveratrol. Exercise is another great way to lower inflammation.

3. Glycation: Glycation is what happens when sugar mixes with proteins and fats to form molecules that promote aging. Advanced glycation end products, or AGEs (Isn’t that an appropriate acronym?), are thought to accelerate your aging process by churning out free radicals and promoting inflammation. One way to avoid ingesting AGEs is to turn down the heat when you cook. The browning effect of high-heat cooking causes these molecules to form. Limiting your intake of sugar-filled foods in general will also help.

4. Stress: Stress initiates the release of a variety of hormones that make your pulse race and cause your blood pressure to rise. The hormone cortisol, released to lessen these effects, also creates problems when it remains chronically elevated. Try practicing relaxation techniques to help manage stress, and get enough sleep every night.

Your genetics may not be the best predictor of how you’ll age. A study involving identical twins suggests that despite genetic make-up, certain environmental factors can add years to a person’s perceived age. Factors such as divorce or the use of antidepressants are the real culprits that cause facial aging.

Researchers obtained comprehensive questionnaires and digital images from nearly 200 pairs of identical twins. The images were reviewed by an independent panel, which recorded the perceived age difference between the siblings.

Study subjects who had been divorced appeared nearly two years older than their siblings who were married, single or even widowed. Antidepressant use was associated with a significantly older appearance..

The presence of stress could be one of the common denominators that caused facial aging. The researchers also suspected that continued relaxation of the facial muscles due to antidepressant use could account for sagging.
