The Art and Science of Filtered Coffee Brewing

Filtered coffee, a timeless classic in the world of coffee connoisseurs, encompasses a delicate balance of simplicity and sophistication. At its core, the process involves the gentle infusion of hot water through a bed of finely ground coffee beans, culminating in a liquid masterpiece that tantalizes the senses.

Unlike its espresso counterpart, which relies on pressurized extraction, filtered coffee harnesses the force of gravity to coax out the flavors locked within the grounds. This unhurried journey results in a brew that is not just a beverage but an experience—a symphony of flavors and aromas that dance on the palate.

Moreover, filtered coffee presents health-conscious consumers with a preferable alternative to other brewing methods. Unlike French press coffee or espresso, which retain oils containing cafestol—linked to increased LDL cholesterol—filtered coffee effectively removes these compounds, ensuring a guilt-free indulgence.

The advantages of filtered coffee extend beyond health considerations. Its meticulously crafted powder yields a brew imbued with a depth of flavor and aroma that instant coffee powders can only aspire to emulate. Furthermore, the use of fresh ingredients in filtered coffee underscores its commitment to quality and authenticity, contrasting sharply with the mass-produced nature of instant coffee.

In essence, filtered coffee transcends mere caffeination—it embodies a ritual, a craft, and a sensory journey. From its humble origins to its enduring appeal, filtered coffee remains a testament to the marriage of tradition and innovation in the pursuit of the perfect cup.

Caffeine Protects Against Parkinson's

Parkinson's disease is a prolonged and advancing movement disorder that is commonly acknowledged as the second most prevalent neurodegenerative condition, following only Alzheimer's disease.

Evidently, caffeine may have a shielding impact against Parkinson's disease. A research study encompassing 8004 Japanese American men aged between 45 and 68 was carried out as part of the Longitudinal Honolulu Heart Program spanning from 1965 to 1968. The individuals were divided into groups based on their consumption of coffee and their overall dietary intake of caffeine.

The findings indicated a significant reduction in the occurrence of Parkinson's disease among those individuals who had greater consumption of coffee and caffeine. The data implied that this result was mainly associated with the intake of caffeine itself, rather than other compounds found in coffee.

Several studies employing case-control and cohort designs have also documented an inverse relationship between the consumption of coffee and caffeine and the likelihood of developing Parkinson's disease.

In a forward-looking study conducted over 22 years and involving 6710 Finnish men and women aged between 50 and 79 at the study's commencement, it was observed that individuals who consumed 10 or more cups of coffee per day had a relative risk of 0.26 for developing Parkinson's disease in comparison to those who abstained from coffee (as reported in the European Journal of Clinical Nutrition, 2007).

The consistent interaction between caffeine and adenosine receptors appears to provide a safeguarding effect on brain cells against neurodegenerative illnesses, contributing to the enduring well-being of the central nervous system. This effect is particularly striking in the context of Parkinson's disease.

Coffee leaves

The shiny, waxed leaves on the side of the main stem of the coffee plant are typically green. For some species or varieties, the young leaves can be bronzed-tipped and are green or dark-green when aging but never brown, except when they are stressed or when they fall down. The leaves of C. arabica and C. canephora experience a life time of 8 months and 7–10 month, respectively, until they reach a length of up to 15 cm.

Coffee leaves contain many different phytochemicals, including alkaloid, flavonoids, terpenoids, amino acids, sucrose, tannins, xanthonoids (mangiferin and isomangiferin), phenolic acids, and catechins.

The range of concentrations of chlorogenic acids in young leaves (35.7–80.8 mg/g of dry matter) were found to be comparable to the one reported for green coffee beans.

Coffee leaves have been found to contain an amount of mangiferin comparable to Mangifera indica leaves. Recently, the accumulation of mangiferin has been demonstrated in the leaves of several coffee species, suggesting that this maybe an excellent natural source of this xanthone.

The leaves of the coffee plants have been used for a long time to prepare tea-like drinks. Especially in West Sumatra, Ethiopia, Jamaica, India, Java, and South Sudan, the infusion is consumed as a traditional food. it has been reported that under an optimum condition for brewing, the coffee leaves tea, particularly from old leaves produces a tea-like taste and color with a subtle coffee aroma with superiority in total phenolic content.

The beverage is believed to help on the treatment of several disorders, for instance anemia, intestinal pain, and fever.

Before preparing the drink, there are different production methods to obtain coffee leaf tea. Most of them include leaf steaming, rolling, and drying.

Chlorogenic acids

Coffee contains many polyphenols, especially CGAs, which have purported antioxidant abilities. Caffeoylquinic acid, as one of the major coffee polyphenols, is an ester of caffeic acid with quinic acid and is often referred to as chlorogenic acid.

Chlorogenic acids are phenolic acids with vicinal hydroxyl groups on aromatic residues that are derived from esterification of cinnamic acids, including caffeic, ferulic and p-coumaric acids with quinic acid.

Chlorogenic acids are naturally occurring phenolic compounds found in all higher plants. Due to their various biological properties, such as antispasmodic, antioxidant, inhibition of the HIV-1 integrase and inhibition of the mutagenicity of carcinogenic compounds, they are very important plant secondary metabolites. There is also evidence to show that chlorogenic acids exhibit anti-inflammatory activities by modulating a number of important metabolic pathways.

Chlorogenic acids exists in raw coffee and is also widespread in many kinds of seeds and fruits such as sunflower seeds and blueberries. It has also been found in the seeds and leaves of many dicotyledonous plants. It is thermally unstable and is readily decomposed to quinic acid and caffeic acid. Lower content of chlorogenic acids has also been detected in potatoes, tomatoes, apples, pears and eggplants, but consumption of these sources accounted for nearly 5–10% of that from coffee beverage source.

Chlorogenic acid strongly influences the taste of coffee, such as astringent, sweet, and sour tastes, which change with the concentration.
Chlorogenic acids

Caffeoylquinic acids in coffee beans

Caffeic, ferulic, and p-coumaric acids are the main phenolic compounds in coffee which derive from trans-cinnamic acid.

Naturally, they may present as mono- or diesters with quinic acid, forming chlorogenic acids, which are known to be the most active antioxidant compounds. Caffeoylquinic acids and particularly 5-CQA (5-O-caffeoylquinic acid) are found to be the most abundant compounds in coffee beans, where they can form vacuolar complexes with caffeine.

Caffeoylquinic acids are cinnamate conjugates derived from the phenylpropanoid pathway. They are generally involved in plant responses to biotic and abiotic stress.

Since caffeoylquinic acids contribute to acidity, astringency, and bitterness of the brewed coffee, they are relevant to sensorial properties of the beverage.

Caffeoylquinic acid compounds are widespread in plants. They protect plants against predation and infection and may have several beneficial functions in the human diet.

Esters formed between hydroxycinnamates and quinic acid represent a major family of plant phenolics. Chlorogenic acid (5-CQA) is the most widespread of all monoesters formed between caffeic and quinic acids.

Due to their antioxidant and antibiotic properties, hydroxycinnamoylquinic acids are involved in numerous biological plant functions such as pest and disease resistance. The caffeoylquinic acids are among numerous phenolic compounds found in plants that are thought to function in defense against predation and parasitism.

In coffee trees, hydroxycinnamoylquinic acids accumulate in beans. This is particularly marked in Coffea canephora where their content can exceed 10 % of dry bean weight.

On a molecular basis, oxidative activity increases in proportion to the number of caffeoyl residues in the molecule. Other potential beneficial effects of caffeoylquinic acid compounds on humans that have been demonstrated in laboratory studies include anti-inflammatory activity; reduced skin aging by inhibiting the enzyme, collagenase; anti-spasmodic activity; antihyperglycemic activity; suppression of melanogenesis.

Coffee can reduce the incidence of gout

Coffee is a sort of soft beverage widely consumed in the world. For example, nearly half of the Japanese adults drink coffee on a daily basis, and over 50% of Americans consume an average coffee intake of 1–2 cups per day.

Gout is the most common inflammatory arthritis in adult males. This disease starts with unexpected attacks, but can become chronic with flare ups that cause joints to suddenly become red, hot, swollen, and tender.

Coffee is one of the most widely consumed beverages in the world and may affect the risk of gout via various mechanisms, including reducing serum uric acid levels and influencing insulin resistance.

Coffee is thought to reduce gout risk by lowering uric acid levels through several mechanisms. Coffee may lower uric acid levels by increasing the rate that human body excretes uric acid. Coffee is also thought to compete with the enzyme that breaks down purines in the body.

Components of coffee other than caffeine may affect the risk of gout by influencing insulin resistance and circulating insulin levels. Higher long-term coffee intake is associated with lower insulin levels and increased insulin sensitivity. Furthermore, several studies and a recent meta-analysis consistently found that coffee consumption was inversely associated with the risk of type 2 diabetes.

Chlorogenic acid and other antioxidants help reduce blood levels of the hormone, insulin. Levels of insulin and uric acid (the chemical that triggers gout) are closely related, and insulin concentrations from coffee consumption may lead to a lower risk of hyperuricemia and gout. When insulin levels are low, uric acid tends to be lower, too.

Hyperuricaemia is commonly recognised as a risk factor for many chronic diseases such as hypertension, diabetes, cardiovascular disease, metabolic syndrome, chronic kidney disease11 and insulin resistance.

Health benefit of coffee: antidiabetes

A significant reduced risk of diabetes among coffee drinkers is consistent with many studies. It was concluded that habitual coffee consumption is associated with a substantially lower risk of Type 2 diabetes (Van Dam, and Hu, 2005).

Harvard investigators followed more than 126, 000 subjects for up to 18 years and found that men who drank more than six cups (48 ounces) of coffee daily reduce they diabetes risk by more than 50% (30% for women). The effect faded with fewer than three cups per day.

Salazar-Martinez and colleagues’ study suggests that long-term coffee consumption is associated with a significantly lower risk for type 2 diabetes mellitus. Salazar-Martinez E, Willett WC, Ascherio A, Manson JE, Leitzmann MF, Stampfer MJ, et al. Coffee consumption and risk for type 2 diabetes mellitus. Ann Intern Med. 2004;140:1-8. [PMID: 14706966] 

In the Pizarra study, a crosssectional study of 1226 randomly selected adults from a small town in Spain, persons who drank coffee at least once per day had a lower risk for diabetes mellitus and impaired glucose tolerance (odds ratio, 0.66 [95% CI, 0.48 to 0.92]; P 0.02) than persons who drank coffee only occasionally, after adjustment for age, sex, obesity, and smoking.

Is coffee an aphrodisiac?

Named for Aphrodite, the ancient Greek goddess of love, an aphrodisiac is a substance or object believed to boost irresistibility or to increase sexual desire, arousal, performance and response.

Chocolate, coffee, and honey are also believed to have aphrodisiac potential.

In a University of Michigan study on the sex- stimulating effects of coffee, findings revealed that people who drank coffee daily were more likely than those who did not to describe themselves as sexually active.

Drinking two to three cups of coffee a day reduces the odds of erectile dysfunction in men, according to a new study from researchers at The University of Texas Health Science Centre at Houston.

Published in the journal PLOS ONE, the study found that men who consumed between 85 and 170 milligrams of caffeine a day were 42 per cent less likely to report erectile dysfunction.

Study found that a reduced likelihood to report erectile dysfunction among men with caffeine intake, especially with 2–3 daily cups of coffee, which is approximately 170–375 mg/day.

Arabica coffee used in traditional medicine

Arabica coffee prepare font the coffee bean, is the most frequently consumed drink around the world; coffee has medicinal properties.

Reported to be analgesic, anaphrodisiac, anorexic, antidotal, CNS-stimulant, counterirritant, diuretic, hypnotic, lactagogue, nervine, stimulant, coffee is a folk remedy for atropine-poisoning, fever, headache, jaundice, malaria, migraine, narcosis, nephrosis, opium-poisoning, sores, and vertigo.

In traditional medicine, different parts of coffee plants are used for influenza, anemia, edema, rage, hepatitis and externally for nervous shock and as stimulant for sleepiness, an antitussive in flu and lung ailments, a cardiotonic and neurotonic, for asthma and many more.

In Yemen coffea arabica is traditionally use as a stimulant, against headaches and kidney stones. The properties of coffee is stimulant of the central nervous system, has a slightly diuretic effect and lipolytic action when use externally as a cream.

Drinking coffee can reduce risk of high blood pressure

Coffee as a health food means the classic beverage brewed from ground coffee beans. It is the coffee, not the milk and sugar that provides health benefits.

Research shows that coffee may actually decrease the chances of getting type-2 diabetes. In addition, coffee is no longer felt to be a risk factor for high blood pressure.

A 12 years study of 155,000 women found that drinking caffeinated cola may be associated with an increased risk of high blood pressure. However, the same causal relationship was not found with caffeinated coffee.

In fact, the study suggested that women who drink caffeinated coffee may actually have a reduced risk of high blood pressure.

A 1989 Norwegian study of 30,000 middle-aged men and women demonstrated that drinking more than one cup of coffee a day is positively correlated with a reduction on both systolic and diastolic blood pressure.

In other words, people in a high-risk group of hypertension who drink more than one cup of coffee a day tend to have lower blood pressure than people who do not.

Research on coffee and heart disease

Coffee is among the most commonly consumed beverages in the United States and is the main source of caffeine intake among adults.

Regular coffee consumption has been associated with a lower risk of Type 2 diabetes mellitus and other cardiovascular risk factors such as obesity and depression.

A Harvard University study published in Circulation in 2015 found that people who drank three to five cups of coffee daily were less likely to die prematurely from any cause.

The study also found that they were specifically less likely to die from heart disease and stroke compared to people who drank little or no coffee. And drinking more than five cups of coffee per day didn’t favourably affect risk of death.

An analysis published in 2013 in Circulation compiled the results of 36 studies on coffee that included more than one million patients. Researchers concluded that people who drank coffee in moderation were significantly less likely to develop cardiovascular disease than those who didn’t drink coffee.

A newly published study (2015) of South Korean coffee consumers found moderate drinkers are less likely to have signs of blocked arteries than people who drank no coffee — or those who drank five or more cups a day.

The study’s participants who consumed between 3 and 4 cups of coffee per day had the lowest risk of clogged arteries developing, Dr. Yoosoo Chang of Kangbuk Samsung Hospital in Seoul and colleagues found.

Coffee reduce risk of cancer

Coffee is widely consumed worldwide, and is substantial evidence from both laboratory and animal studies suggest its ability to reduce the risk of cancer.

Cancer is one of the most feared diseases. The carcinogenic potential of coffee has been investigated in several long term animal bioassays.

Studies suggest those who enjoy a cup of coffee every day or nearly daily have a lower risk for liver cancer than those who rarely sip a cup.

Feeding high levels of coffee as part of the diet did not produce tumors in either rats or mice (Nehling & Debry 1996).

On the contrary, some studies reported that instant coffee resulted in a decreased incidence of spontaneous tumors (Stadler 1990). The presence of antioxidants in coffee can explain the anticancer property of the beverage, but there are other compounds which might be involved.

According to the scientists, caffeine and caffeic acid, major coffee constituents have been shown to suppress mammary tumor formation in animal models and to inhibit DNA methylation in human breast cancer cells, respectively.

Coffee may also reduce risk through decreasing inflammation and influencing estrogen metabolism.

Research by National Institute of Environmental Health Sciences, North Carolina reported that cafestol and kahweol, which are naturally occurring diterpenes in coffee, have proved to have anti-carcinogenic properties.

Alzheimer’s disease and coffee

Over the past few years there has been increasing interest in the health benefits of coffee, as coffee consumption has been linked with better cognitive functioning and a lower risk of Alzheimer’s disease.

There are several studies showing that people who drink two or four cups of coffee each day are less likely to develop Alzheimer’s dementia that are people who do not drink coffee.

Scientific studies have shown that caffeine and other substances in coffee have a number of different effects on the brain that would be expected to improve one’s chances of avoiding dementia.

In one findings, shows that caffeinated coffee induces an increase in blood levels of growth factors GCSF (granulocyte colony stimulating factor). Researchers note that moderate coffee drinking (4 to 5 cups per day) starting in middle age may provide protection for Alzheimer’s symptoms and disease.

Based on animal study data, caffeine may prevent Alzheimer’s disease by protecting against beta-amyloid toxicity through adenosine A1 receptor inhibition.

Coffee also reduces inflammation and improves the health of the endothelial lining of arteries. Some substances in coffee also have significant antioxidant effects.

Together these beneficial effects of coffee offer the brain protection from some of the primary pathological processes that cause Alzheimer’s and other neurodegenerative disease to progress.

In Canadian Study of Health and Aging, daily coffee drinking lowered Alzheimer’s risk by 31 percent during five years follow-up.

In addition to direct preventive effects against Alzheimer’s disease, caffeine consumption may also indirectly inhibit cognitive decline via prevention of type II diabetes, a disease associated with accelerated rates of cognitive decline.

Coffee reduces risk of dementia

Dementia is a group of conditions that gradually destroy brain cells and lead to progressive decline in mental function which is usually progressive and eventually severe.

The epidemiological evidence suggests that coffee consumption reduces the risk of cognitive decline, dementia and AD.

The caffeine in coffee is implicated as the active component associated with risk reduction of cognitive decline and dementia among coffee drinkers.

When people with mild cognitive impairment (a condition of loss of memory and other mental functions less severe than outright dementia) drank three to five cups a day, they cut their risk of progressing to dementia.

Scientific studies have shown that caffeine and other substances in coffee have a number of different effects on the brain that would be expected to improve one’s chances of avoiding dementia.

Caffeine grows brain cells in the areas of the brain responsible for long-term memory. Caffeine increase short-term memory, concentration, and the ability to think clearly.

Coffee reduces inflammation and improves the health of the endothelial lining of arteries. Some substances in coffee also have significant antioxidant effects.

These all effects would also tend to help prevent metabolic syndrome, heart disease, diabetes and other conditions that increase the risk of dementia.

Some 1409 participants of the Cardiovascular Risks Factors, Aging and Dementia (CAIDE) were followed for an average of 21 years. By 1998, a total of 61 cases were identified as demented (48 with AD).

Coffee drinkers at midlife has a lower risk of dementia and AD later in life compared with those drinking no or only little coffee.

The lowest risk (65% decrease) was found in people who drank 3-5 cups per day.

Drinking coffee reduce risk memory loss

Most people known that a cup of coffee can increase mental alertness and concentration and counter the effects of tiredness and fatigue.  In actual facts coffee is a psychoactive drug that acts on human mood, behavior, and intellect.

Drinking coffee may help when people feel retired, lacking in energy, and in during depression.
The coffee in coffee appears to reduce the risk of memory loss and Alzheimer’s by blocking the effects of adenosine. Caffeine also increases arousal and speeds communication among nerve cells in the brain.

This increase in alertness, a sense of being sharper, is what leads to better performance to cognitive tests, including test of memory.

In a study published recently, scientists at the University of California found that people over sixty-five drinking coffee at least five times a week, reduced their memory loss up to 20 percent compared with those who did not drink coffee at all.

Short - Term Effect Of Coffee On Health

Coffee beverage
Stuffs that during brewing dissolve in water to create the drink which are classified as nonvolatile taste components (comprises of caffeine, trigonelline, phenolic acids, chlorogenic acid, carbohydrates, amino acids and other minerals) and volatile aroma components comprise of organic acids, aldehydes, ketones, esters, amines and mercaptans.

A cup of coffee, depending on its strength might contain some 10-100mg of caffeine. Some types of coffee might as well contain important amounts of the B-vitamin niacin, even though this nutrient is of course with pleasure accessible from other foods as well.

Caffeine-containing tablets or medications need not be taken as well as cups of coffee or tea, as this would again increase the true value of dosage. The effects of caffeine differ from person to person; some individuals may drink several cups of coffee in an hour and may also have zero effects, while other person may feel a strong effect after just one serving.

Caffeine is actually a drug, which has been widely used for centuries. Its main effect is that it is a soft stimulant of central nervous system (CNS), assisting to decrease feelings of tiredness and fatigue. However, usual use might lead to “habituation”; that is, no net advantage from use but, rather, a negative effect if the drug is not actually taken.

Besides the above mentioned CNS stimulant outcome, caffeine as well temporarily increases heartbeat, increases the blood pressure, and further stimulates the action of the lungs; increases basal metabolic rate (BMR), and help to promotes urine production; and it also relaxes smooth muscles, particularly the bronchial muscle.

Caffeine is well used in treating migraine disease, either alone or in combination. It enhances the action of the ergot alkaloids, which is used for the treatment of this problem, and further increase the potency of analgesics such as aspirin. It could to some extent relieve asthma attacks by dilating the bronchial airways.

Caution and Warning
Too much of caffeine could also produce restlessness, nausea, headache, tense muscles, cardiac arrhythmias (irregular heartbeats) and sleep disturbances. Because caffeine increases the production of stomach acid it might even worsen ulcer symptoms or cause acid reflux (heartburn). Consuming coffee in evening might disrupt sleep and may cause insomnia.

Caffeine needs to be used with caution by people with heart disease and people with high blood pressure (hypertension), and also by those people who are suffering from eye disease glaucoma.

Caffeine medications must not be generally taken by children. Many children are already drinking huge amounts of caffeine in drinks and food. In this connection, a nutritional concern is that children might select fizzy drinks in preference to milk, thus getting zero calories at the expense of valuable nutrients.

Cafestol and kahweol in coffee

Cafestol and kahweol are fat soluble compounds knows as diterpenes, which have been found to raise serum lipid levels (causing a rise in total cholesterol, low-density-lipoprotein (LDL) cholesterol, and triglycerides) and affect liver.

The structure of cafestol and kahweol is nearly identical, differing in only in the degree of saturation of one conjugated bond to the furan ring.

The diterpenes occur largely as fatty acids esters, esterified at the primary hydroxyl group.  Some cafestol and kahweol are extracted from ground coffee during brewing, but are largely removed from coffee by paper filters.

Diterpenes exhibit good stability at high temperatures, but they can form dehydro-derivative (dehydro-cafestol and dehydro-kahweol) in small amounts when roasting temperatures are raised.

Because coffee beans are high in cafestol and kahweol, ingestion of coffee beans or grounds on regular basis may also raise serum and LDL cholesterol.

Scandinavian-style boiled coffee and Turkish-style coffee contained the highest amounts, equivalent to 7.2 and 5.3 mg cafestol per cup and 7.2 and 5.4 mg kahweol per cup, respectively.
Cafestol and kahweol in coffee

Flavored coffee beans

Flavored coffees are generally made with beans that are roasted to a medium brown, and then mixed with liquid flavoring agents.

The flavors used in such products are extracts of flavor source that are absorbed into the coffee bean.

The Arabs were the first coffee connoisseurs to add such spices as cinnamon to the beloved brew.

Other Middle Easterners followed, with the addition of cardamom, cloves, nutmeg, allspice, and even ground nuts.

Flavored while-bean coffees – hazelnut and Irish creams as well as chocolate raspberry, cinnamon and countless other are readily available nowadays.

Once coffee was introduced to the western world, the now- auditioned cream and sugar added to brewed coffee.

Some flavored-coffee fans enjoy adding the flavorings themselves, in the way of syrups, to the beverage after it has been brewed.

Flavored coffees are greater for special occasion or a little personal indulgence. Health conscious people who want to reduce their dietary fat are substituting flavored coffee for fat and cholesterol-laden desserts. 

Flavored coffee contain only 5 calories per serving to weight watches can get rich taste without feeling guilty.

Beneficial Drinks of Coffee

Coffee is one of the most widely consumed beverages in the world. Over 500 billion cups are consumed annually. Coffee is currently grown in over fifty countries and is second only to petroleum in global trade activity and value.

Coffee is not usually thought of as health food, but a number of recent studies suggest that it can be a highly beneficial drink.

Researchers have found strong evidence that coffee reduces the risk of several serious ailments, including diabetes, coronary heart disease and cirrhosis of the liver.

It also reducing the risk of several cancers, rheumatoid arthritis and possibly Alzheimer’s disease.

Habitual coffee consumption appears to be associated with a lower risk of type 2 diabetes.

Coffee contains antioxidants that help control the cell damage that can contribute to the development of the disease.

Larger quantities of coffee seem to be especially helpful in diabetes prevention. Researchers found that people who drank four to six cups of coffee a day had a 28 percent reduced risk compared with people who drank two or fewer. Those who drank more than six had a 35 percent risk reduction.

There was study in Amsterdam that components in coffee seem to help the body metabolize sugar, thereby reducing the risk of diabetes, which affects 130 million people worldwide.

Some studies show that cardiovascular risk also decreases with coffee consumption. Using data on more than 27,000 women ages 55 to 69 in the Iowa Women’s Health Study who were followed for 15 years, Norwegian researchers found that women who drank one to three cups a day reduced their risk of cardiovascular disease by 24 percent compared with those drinking no coffee at all.

The antioxidants found in coffee have been found to inhibit inflammation and thereby reduce risk of cardiovascular and other inflammatory disease in post menopausal women.

The most protective effect was found at a dose of 1 to 3 cup of coffee per day.

In males, consumption of 8 or more cups of coffee a day reduce d the risk of cerebral infraction (stoke) when compared to non coffee drinkers.

In another analysis, published in July in the same journal, researchers found that a typical serving of coffee contains more antioxidants than typical servings of grape juice, blueberries, raspberries and oranges.

Researches caution that coffee is not for everyone and that people with hypertension, children, elders and pregnant women are most susceptible to adverse affects.

Caffeine in Coffee

Caffeine in Coffee
The caffeine in coffee that wakes you up in the morning also makes you more responsive to stress. Caffeine raises levels of the stress hormone epinephrine and also makes us more responsive to the epinephrine circulating in the blood stream. As a result, your heart beats faster, your blood pressure increases, blood sugar rises – and you feel an initial jolt of energy. However, this jolt puts your body into fight or flight mode. According to research, drinking 1 cup of coffee in the morning can keep you in fight or flight mode until well into the evening. This shows that four cups of coffee raises the hormones epinephrine by 32 percent all day long. Also, people who drink coffee report feeling more stressed throughout the day. Any outside stress, such as a frenzied day at work, will bump your epinephrine level even higher.

In short, caffeine makes you particularly sensitive to stress. Your morning coffee may determine whether you suffer an anxiety attack as a deadline approaches or whether you can successfully talk your self through the moment and stay on task.

This all spells trouble for blood sugar control. We’ve known for some years that caffeine can make cells resistant to insulin even in people who don’t have diabetes. For example, in one study, researchers monitored the blood pressure, heart rate, and blood sugar for 2 hours after seven men took either a placebo or a caffeine pill. Caffeine increased insulin levels by 42 percent and decreased insulin sensitivity by 25 percent. Though blood sugar was roughly the same in all group, none of the study subjects had diabetes.
