Can Coffee Reduce The Risk Of Diabetes?

Diabetes is a disease in which the body does not produce or properly use insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles.

Coffee reduces risk of diabetes
Research suggests that people who drink coffee are less likely to get type 2 diabetes. It isn't known whether the caffeine or some other ingredient in coffee is responsible for its protective effects.

The researchers wanted to see whether there is a link between diabetes and drinking coffee and green, black, and oolong tea. Participants completed a detailed questionnaire about their health, lifestyle habits, and how much coffee and tea they drank. The questionnaire was repeated at the end of the 5-year follow-up period.

When other factors were accounted for, researchers found that the more green tea and coffee participants drank, the less likely they were to get diabetes. People who drank six cups or more of green tea or three or more cups of coffee each day were about one-third less likely to get diabetes. The link was stronger in women than in men. No pattern was seen with black or oolong tea. (see Diabetes Symptoms)

Vitamin D and Calcium May Lower the Risk for Type 2 Diabetes in Women
A lack of vitamin D and calcium may be linked to getting type 2 diabetes. More than 80,000 women who took part in the Nurses' Health Study. Over the course of 20 years, over 4,800 women developed type 2 diabetes. The researchers found that a combined intake of over 1,200 milligrams of calcium and over 800 units of vitamin D was linked with a 33% lower risk for type 2 diabetes (as compared to women who took much smaller amounts of calcium and vitamin D). The results show that consuming higher amounts of vitamin D and calcium help lower the risk for type 2 diabetes in women.

Diabetes is a disorder characterized by hyperglycemia or elevated blood glucose (blood sugar). Our bodies function best at a certain level of sugar in the bloodstream. If the amount of sugar in our blood runs too high or too low, then we typically feel bad. Diabetes is the name of the condition where the blood sugar level consistently runs too high. Diabetes is the most common endocrine disorder.

Coffee Health - New Antioxidant On The Block

Green coffee beans have supplied a new player in the antioxidant arena. An extract of green coffee beans has been found to have a stronger antioxidant effect than established antioxidants like green tea and grape seed extract.

The active constituent in coffee that is responsible for its many health benefits is a compound called chlorogenic acid. It neutralizes free radicals, and addresses the problem of hydroxyl radicals, both of which can lead to cellular degeneration if left unchecked. Chlorogenic acid also helps regulate metabolism. Compared to green tea and grape seed extract, green coffee bean extract is twice as effective in absorbing oxygen free radicals.

One of the advantages of using the green coffee bean extract is that the negative effects of coffee are avoided. The chlorogenic acid is thought to boost metabolism by changing the way glucose is taken up by the body. And it does contain caffeic acids, which give a boost to energy levels like regular coffee does. But unlike boiled coffee, green coffee bean extract contains no cafestol, which is a diterpene. Along with its diterpene relative kahweol, cafestol increases concentrations of the 'bad' cholesterol, LDL, to levels that over a lifetime might increase the risk of coronary heart disease by as much as 20% These diterpenes also had an effect on the levels of liver enzymes measured. When these are elevated it is an indicator of stress on the liver. However the study that measured this found this was a transient effect, and also that the levels of liver enzymes were much lower than those with liver disease.

As a side note on the health effect of the diterpenes found in regular coffee, it was found that by simply drinking filter coffee, none of these effects on cholesterol levels or the liver took place. The coffee filter removed the offending diterpenes. And levels of these diterpenes in instant coffee are low.

Other benefits of green coffee bean extract include an increase in the effectiveness of pain killers, especially for migraine medications; a reduction in the risk of diabetes; and assisting the body burn a higher proportion of lipids (fats) compared to carbohydrates, which could help with muscle fatigue for athletes and bodybuilders.

Interestingly, on the subject of caffeine and liver disease, further studies have indicated it may in fact support liver health for some people. Those who were at high risk of developing liver disease due to drinking too much alcohol were found less likely to suffer liver damage if they drank more than two cups of coffee or tea a day. This was a population based study, not a clinical trial, and so is not conclusive on the subject. But it does offer some promising information. Those drinking in excess of two cups or more a day were half as likely to develop liver disease compared to those drinking less than one cup a day. Researchers do not know what caused this protective effect.

One of the criticisms of coffee in regards to health is that it leaches calcium from the bones. But this effect has been found to be overemphasized, at least in children. And adults who consume a diet with sufficient levels of calcium will be protected from the small amount of calcium that is lost due to coffee consumption.

So the old axiom that caffeine can stunt a child's growth is a myth. It was based on the fact that in older studies, caffeine was associated with low bone mass  because those studies were done on elderly people who both drank a lot of coffee and had diets that were low in calcium. Recent studies in the US followed 80 teenagers over 6 years, and found no difference in the bone density of those with a high level of caffeine in their diet, compared to those teenagers who had little caffeine. Other studies determined that the amount of calcium lost from bones is small and can be balanced by having sufficient calcium in your diet.

Coffee Health Benefit: Slower Liver Damage Progression

According to Reuters, drinking coffee on a daily basis may slow liver damage from a hepatitis C infection. Patients who are diagnosed with hepatitis eventually have to deal with liver problems, chronic inflammation and scarring of liver tissue known as cirrhosis of the liver. Without a proper functioning liver, the body has trouble breaking down fatty acids and removing toxins from the body. Liver cancer is a possibility for people with hepatitis C. Cirrhosis of the liver is also caused by excessive, long-term alcohol consumption, although this study only dealt with hepatitis C cases.

In the study, 766 people were monitored. Patients who drank three or more cups of coffee reduced the rate of liver damage by 53% over a four-year period. Why does coffee have such a positive effect on this particular disease? With myriad antioxidant compounds, the key to slowing liver damage through coffee is unknown at this point, although curiously enough, drinking tea does not have the same health benefits as drinking coffee in this particular case. It is something specific to the coffee bean that is slowing the disease. Aside from being high in antioxidants, coffee also has an effect on insulin levels, which could be related to the benefits for hepatitis patients.

In addition to drinking copious amounts of coffee, eating plenty of fresh fruits and vegetables, and drinking herbal teas, such as red clover and dandelion, which act as blood cleansers, can support liver functioning and slow cirrhosis of the liver.
