Good Morning Ladies & Gentleman! Are you drinking tea or coffee right now? Popular belief labels tea as a health drinks and coffee as bad :-) How much credibility can we give to this general statement and popular belief? :-)
In an attempt to survive the rigors of our stressful lives, many people turn to fuel their bodies by consuming coffee. Caffeine is the principal element in coffee that is responsible for improving concentration and extending the time before the onset of fatigue. After as little as one cup, caffeine absorbs to almost every cell in the body, where it stimulates the central nervous system by elevating blood glucose levels giving an allusion of an energy surge. There, caffeine blocks a chemical called adenosine that signals to the brain it is tired; turning it into that invigorating buzz coffee drinkers crave. Caffeine is a psychoactive drug that can lead to dependency. Researchers suggest that caffeine is helpful in combating fatigue, increasing alertness and efficiency, but should be limited to two cups a day for optimal results. When using coffee as an antioxidant source, experts recommend that it is best to spread your coffee intake throughout the day stressing that fruits and veggies are still the ideal choice.
The impact of coffee on the overall health of mankind has been an extensive subject of survey over decades altogether. The resulting research has always reported a series of varied results, ranging from ill effects to moderate effects and even instances of a beneficial role of the drink. Let's analyze the pros and cons of coffee and tea in this article from various aspects with indications from different research reports.
Some research suggests that coffee effectively reduces the risk of being effected by colon cancer, though that is only likely to happen if the consumption is more than four cups a day. May I ask you, are u going to drink more than four cups a day of coffee? If the answer is no, then you won't be able to benefit from it.
There is no doubt that coffee also has an amazing effect on mental alertness.
A set of Chinese studies also report that coffee can reduce the effects of Parkinson’s disease.
In addition, various American and Scandinavian studies show that the decaf as well as regular coffee can help in the reduction of the risk of being effected by type-2 diabetes.
There is also a possibility of coffee being effective in reducing the constriction of airways in asthma sufferers, when consumed in moderation.
Well, that's all the benefits of coffee according to some studies and research conducted. Now, let's analyze the detrimental effects of coffee to our health.
Coffee Increase the Risk of America’s Main Cause for DeathCoffee consumption significantly increase risk of developing heart disease and succumbing to a heart attack. Heart disease is not only the foremost killer of adult Americans; associated cardiovascular problems can create substantial debility in older adults. Some of the factors that contribute to developing cardiovascular disease include: high cholesterol, diabetes, high levels of homocysteine, elevated blood pressure, abdominal obesity, stress, arrhythmias, low daily fruit and vegetable consumption. Coffee consumption negatively impact many of these risk factors. Coffee raises serum cholesterol. Coffee drinking causes increases in serum homocysteine levels. Coffee raises blood pressure and increases the incidence of arrhythmias. Coffee drinking significantly increases levels of stress hormones. Chronic stress and constant release of excess cortisol (which is affected by coffee) produces a more frequent incidence of abdominal obesity, further increasing heart disease risk!
Coffee Increase Chronic Stress
Coffee consumption increase our experience of stress by stimulating the release of the stress hormones cortisol, epinephrine, norepinephrine and the glucocorticoids. The continuous presence of these hormones not only has a damaging effect on a number of different physiological systems, but can also accelerate the aging process. Although short-term stress can be psychologically motivating and can mobilize physiological processes, the extended presence of stress-related hormones is detrimental and damaging. When stress hormones are chronically elevated, which occur as a result of our intense lifestyle as well as a consequence of ingesting coffee, mental concentration is short-lived as anxiety and feelings of tension increase, while fine motor coordination is impaired; the immune system is suppressed, digestion and elimination are impaired and the body’s normal repair mechanisms are inhibited, thereby accelerating the aging process!
Coffee Lowers Production of DHEACoffee decrease levels of the steroid hormone, dehydroepiandrosterone, commonly known as DHEA. DHEA seems to have a protective effect on the body and appears to be involved in defending against the negative effects of aging. Some of the physical and physiological changes of aging are related to the decline of many hormones including DHEA that assist in repair of cells and tissues, enhance cognition and memory, and help maintain the body’s physiological processes. Coffee negatively impact these complex hormonal systems!
Coffee aggravates Dementia and Alzheimer's diseaseAlzheimer’s disease and associated dementia are not a normal part of aging; BUT current statistics reveal that approximately 7% of the population age 65 and over suffers from Alzheimer’s disease. Although coffee consumption are not directly related to Alzheimer’s disease risk, hypertension and other vascular abnormalities appear to be linked to a predisposition to developing the disease. Coffee and caffeine adversely affect blood pressure and the vascular system.
Coffee Reduce Minerals Absorption and Bone Density
Although caloric requirements often decrease with age, nutritional requirements increase and thus, it can be difficult to maintain adequate vitamin and mineral status. For instance, deficiency of vitamin B-12 occurs as frequently as in 20% of the elderly, but can be difficult to detect. Coffee interfere with absorption and increase excretion of several vital minerals necessary for maintaining cardiovascular health, preserving bone density and preventing chronic diseases, including calcium, potassium, magnesium and iron.
Today, 10 million of U.S citizens are diagnosed with osteoporosis and 33 million more suffer from low bone mass, which subsequently increases their risk of developing osteoporosis or associated fractures. One out of every two women and one in four men over 50 will have an osteoporosis-related fracture in their lifetime. Osteoporosis is responsible for more than 1.5 million fractures annually. Usually thought of as a disease of post-menopausal women, osteoporosis is increasingly a problem in elderly men: more than 2 million American men have osteoporosis and each year, 70,000 men fracture a hip.
With increasing age, the probability of developing osteoporosis also increases. Osteoporosis has no single cause. It is related to a complex series of hormonal interactions that regulate bone formation and reabsorption. Hormone levels, including estrogen and testosterone, are both important in mineral deposition and activity of osteoblasts, the cells which create new bone.
Bone density is not only influenced by mineral intake, absorption and excretion but also by maintenance of the bone’s mineral composition. Adequate calcium and vitamin D is critical for mineralization of bone, and coffee intake not only interferes with calcium absorption but also increases urinary calcium excretion. Consumption of acidic foods including coffee increases the leaching of minerals from the bone due to overall increased metabolic acidity. Minerals appear to have a buffering effect on the bloodstream and are subsequently leached from bone to realkinalize the blood when pH levels have shifted too far into acidity. Excess acidity has been associated with negative calcium balance and increased excretion of calcium.
Caffeine’s Interaction with Pharmaceutical DrugsThe body perceives caffeine as a drug that needs to be detoxified by the liver through the cytochrome P450 (CYP) 1A2 pathway. A number of other substances are also metabolized via this pathway, including a number of pharmaceutical medications. These include anti-arrhythmic drugs, the selective serotonin reuptake inhibitor antidepressants, brochodilators and the quinolones, a group of broad-spectrum antibiotics that includes Ciproflaxacin, among others. The interference among these chemicals may cause toxic effects from the increased levels of either caffeine or medications, or both, in the bloodstream. As people tend to take increasing numbers of pharmaceutical drugs with age, these interactions can become significant. The presence of caffeine increases the workload for the detoxification processes of the liver.
Women who take estrogen replacement therapy should be concerned about caffeine intake. Estrogen inhibits caffeine metabolism, therefore simultaneous use of caffeine and estrogen can increase serum concentration of both chemicals, increasing the risk of toxicity or adverse effects.
We are constantly being subjected to chemicals, environmental toxins and free radicals that directly damage both cellular DNA and their biochemical structure as well as interfere with the ability to repair the effects of constant injurious onslaughts. Caffeine and coffee impede the processes of constant repair, which are necessary to keep functioning in optimal condition. Eliminating caffeine and coffee from the diet can support the process of aging with grace and improved health.
Aside from that, the following characteristics of coffee have an adverse effect on the aging process:
Coffee Affects the Endocrine SystemCoffee Elevates Stress Hormones. Caffeine in coffee elevates the stress hormones cortisol, epinephrine (also known as adrenaline) and norepinephrine. This elevation is present even hours after consumption. Chronic metabolic acidity associated with coffee consumption stimulates cortisol secretion, further activating the stress response, leading to a more rapid aging process. Decaffeinated coffee also stimulates the autonomic nervous system. The purpose of this “fight or flight” response is to provide the body with a temporary energy boost for intense physical activity by increasing heart rate and blood pressure to create a sense of “emergency alert.” Circulation of oxygen to the brain and extremities is decreased, the immune system is suppressed, and normal circadian rhythms are disrupted. With today’s sedentary lifestyle, the continual state of increased stress resulting from coffee and caffeine consumption dramatically accelerates the aging process and compromises the nervous system.
Detrimental Effects of Coffee and Caffeine on Aging
• Coffee Increases Gastroesophogeal pressure exacerbating heartburn and acid reflux. Consumption of both decaffeinated and regular coffee increase gastroesophogeal pressure increasing incidence of heartburn, acid reflux and chronic gastrointestinal reflux disease.
Coffee Increases Intraocular PressurePeople over the age of 60 have a greater risk of developing damage to the optic nerve caused by glaucoma, which is most often due to increased intraocular pressure. In healthy adults, consumption of caffeine in regular coffee increases intraocular pressure as well as systolic and diastolic blood pressure, and increases intraocular pressure to a greater extent than drinking herbal tea. Consumption of both caffeinated and decaffeinated coffee demonstrably increases intraocular pressure. Magnesium deficiency is also linked to glaucoma, and coffee interferes with magnesium absorption.
Coffee Increases Risk of Developing Rheumatoid Arthritis Rheumatoid arthritis has a common onset of middle-age, between 30 and 50, but it is a chronic degenerative disease that often worsens with age. Preliminary studies indicate that regular coffee consumption can increase the risk of rheumatoid arthritis through the higher levels of rheumatoid factor. Decaffeinated coffee consumption is linked to increased incidence rheumatoid arthritis onset. Other studies found inconclusive results. Significantly, low levels of the hormone DHEA are observed in women who subsequently develop rheumatoid arthritis.
Coffee Affects Erectile DysfunctionCaffeine consumption is associated with increased incidence of erectile dysfunction in adult men.
Coffee Interferes With Ability to Fall Asleep in Older Adults A study examining the ability of older adults (age 67 or older) found the use of caffeine interfered with their ability to fall asleep. Reduced quality sleep has been found to increase insulin resistance which can lead to type 2 diabetes and heart disease.
Ooops... it seems that based on the scientific evidence & general common sense, the detrimental effects of drinking coffee far outweighs it's benefits :-) As people age, their ability to break down caffeine decreases and interactions between caffeine and prescription medications can become more problematic. Caffeine and coffee also increase susceptibility to many of the chronic diseases associated with the aging process. As people get older, they would do well to avoid coffee.
And now, let's find out the effects of drinking tea and it's effects on our health
Tea helps prevent diseases such as Alzheimer's. Tea may also help keep bones strong to help fight against Osteoporosis. Osteoporosis affects peoples posture which affects the way they walk. Drinking tea may help you ward off Osteoporosis which is very important. Unlike coffee, tea helps your teeth. Coffee makes your teeth discolored and brittle. However tea has antioxidants that prevent cavities and unlike coffee, tea doesn't stain your teeth. Coffee drinkers are advised to visit the dentist a minimum of 2 times per year unlike non-coffee drinkers who may got once a year. That impliedly means non-coffee drinkers would be able to save more money from flowing to dentist..ha ha.. Tea may be more vital to your health than you think. Coffee just suppresses your appetite making you not want to eat. However, tea helps speed up your metabolism which causes you to burn fat faster and helps you to lose weight alot quicker. To those who wants to keep fit & slim, you know what to do :-)
Well, well, well, so if you guys and gals would like to avoid accelarating your aging process, to lead a less stressful life, to fall asleep easily and indulge in your world of fantasy, to avoid those chronic disease, to have a longer life, and not forgetting to keep fit and slim, you know what is best for your health :-) The choice is yours!
