TOP 10 QUIRKS AND PERKS OF CAFFEINE

Caffeine – Top 10 Quirks

1. Cardiovascular problems

Caffeine increases heart rate, elevates blood pressure and can contribute to the development of heart disease. Drinking both decaf and regular coffee may increase cholesterol and homocysteine, the biochemical that science has linked to increased risk for heart attack. Caffeine is also linked to coronary vasospasms. Coronary vasospasms cause 20% of all fatal heart attacks that kill otherwise perfectly healthy people.

 2. Stress

Caffeine stimulates the excretion of stress hormones, which can produce increased levels of anxiety, irritability, muscular tension and pain, indigestion, insomnia and decreased immunity. Increased levels of stress can keep you from making healthy responses to normal daily stress.

3. Emotional Disturbances

Anxiety and irritability are hallmark mood disturbances associated with caffeine consumption, but equally important are depression and attention disorders. Depression may occur as part of the letdown after the stimulant effects of caffeine wear off. It may also appear during the recovery period after quitting caffeine while the brain’s chemistry is readjusted. Rather than increasing mental activity, caffeine actually decreases blood flow to the brain by as much as 30% and negatively affects memory and mental performance.

4. Blood Sugar Swings

Diabetics and hypoglycemics should avoid caffeine. Caffeine stimulates a temporary surge in blood sugar followed by an overproduction of insulin, which causes a blood sugar crash within hours. This rollercoaster causes weight gain since insulin’s message to the body is to store excess sugar as fat.

5. Gastrointestinal Problems

Many people experience a burning sensation in their stomach after drinking coffee because coffee increases the secretion of hydrochloric acid, which leads to an increased risk for ulcers. Coffee, including decaf, reduces pressure on the valve between the esophagus and the stomach so that the highly acidic contents of the stomach pass up to the esophagus, which can lead to heartburn and gastro-esophageal reflux disease.

6. Nutritional Deficiencies

Caffeine inhibits the absorption of some nutrients in addition to causing the urinary excretion of calcium, magnesium, potassium, iron, trace minerals and all essential elements necessary for good health.

7. Male Health Problems

Milton Krisiloff, MD, has found that in the majority of cases, men can significantly reduce their risk for urinary and prostate problems by making dietary changes, which include eliminating coffee and caffeine.

8. Female Health Problems

Fibrocystic breast disease, PMS, osteoporosis, infertility problems, miscarriage, low birth weight and menopausal problems such as hot flashes are all exacerbated by caffeine consumption. Women on birth control pills are particularly at risk since they tend to have a decreased ability to detoxify caffeine.

9. Aging

Many people find that in their 40s, they can no longer tolerate the same level of caffeine consumption they could in their 20s and 30s. Production of DHEA, melatonin and other vital hormones decline with age, but caffeine speeds up that process. Caffeine dehydrates the body and contributes to aging of the skin and kidneys. It has been shown to inhibit DNA repair and slow the ability of the liver to detoxify foreign toxins.

 10. Adrenal Exhaustion

Caffeine consumption leads to eventual adrenal exhaustion, which can leave you vulnerable to a variety of health disorders related to inflammation and fatigue.

Caffeine – Top 10 Perks

1. Alertness

Even in relatively low doses of 100 milligrams (the amount in about 8 ounces of ordinary brewed coffee), caffeine makes people more alert.

2. Mood

At 200 milligrams people report an improved sense of well-being, happiness, energy, alertness and sociability.

3. Concentration

Studies suggest that caffeine can help you perform a variety of cognitive tasks, such as recognizing visual patterns, more quickly.

4. Performance

Research shows if 3-9 milligrams of caffeine per kilogram of body weight is consumed one hour prior to exercise it increases endurance.

5. Reduce muscle pain

Stanley Segall, Ph.D., has found that caffeine might stimulate the release of B-endorphins and hormones that depress the sensation of pain or discomfort.

6. Treat headaches and increases effects of medications

Caffeine constricts blood vessels and helps the body absorb medications more quickly, which is why it is added to some pain medications.

7. Prevent diabetes

Coffee contains minerals and antioxidants which help prevent diabetes. Frank Hu, M.D., one of the authors of The Harvard Study, theorizes it may be because caffeine stimulates muscles to burn fat and sugar more efficiently.

8. Increase your antioxidants intake

Antioxidants in caffeine help to stabilize free radicals and stop them from doing damage. If a free radical is formed in a cell and nothing is done, it can damage the DNA of the cell.

9. Dodge diseases

Caffeine keeps the dopamine molecules active, preventing diseases like Parkinson’s and Alzheimer’s disease. Harvard researchers have found that men who drink four cups of caffeinated coffee a day are half as likely to develop Parkinson’s disease as those who refrain from consuming caffeinated beverages.

10. Bring relief to asthma

Drinking a moderate amount of caffeine can be therapeutic for people with asthma. Caffeine in the form of coffee may be used to prevent an asthma attack in emergency cases, but is not intended to replace medication.
