However, moderate coffee consumption does not harm them either
According to the research, it doesn’t matter whether the coffee is caffeinated, decaffeinated, sweetened or unsweetened. Only the time of drinking is decisive for the diabetes-inhibiting effect.

Only the midday coffee shows a positive effect
"Our findings strongly suggest that only the coffee that is drunk with lunch can reduce the risk of diabetes, ”write Dr. Daniela S. Sartorelli and her colleagues from the University of Sao Paulo in Ribeirao Preto, Brazil, im "American Journal of Clinical Nutrition". The researchers have not yet been able to clarify why the timing of coffee consumption is so crucial. However, they suspect that the timing of the meal affects the sugar metabolism.
Fewer cardiovascular deaths
There is no question that coffee has a health-promoting effect in many areas. Another study: women who drink up to six cups of coffee a day not only have healthier hearts, they even live longer than coffee grouches. This effect was not observed in men. However, moderate coffee consumption does not harm them either. This is what the research team around Esther Lopez-Garcia reports in the journal "Annals of Internal Medicine" citing two long-term studies with a total of over 100,000 participants. The research team evaluated the "Nurses Health Study", attended by around 85,000 women, as well as the "Health Professionals Follow-up Study" with 42,000 male participants. The result: women who drank two to three cups of coffee a day benefited the most. In this group there were a quarter fewer deaths from cardiovascular disease during the entire study period (1984 to 2004). For other types of death, the risk of death fell by 18 percent. However, the researchers warn against jumping to conclusions: Whether the lower mortality is actually due to coffee consumption has not yet been proven.
Drink coffee with a clear conscience
Experts confirm: moderate coffee consumption does not harm your health. "With three to four cups of filter coffee a day, nobody needs to worry about their health"says the Viennese nutritionist Gernot Faustmann. Caffeine has a stimulating effect and temporarily increases blood pressure. That is why it has been warned for years that coffee increases the risk of heart attacks. But that has now been refuted. "An effect on the cardiovascular system is only conceivable at very high doses of seven to ten cups", explains Faustmann. In addition, constant consumption of caffeine leads to habituation, and the body no longer reacts as strongly to it. The thesis that coffee dehydrates the body is also long out of date.
Protection against cancer?
Instead, the positive effects of coffee are moving more and more into the focus of science. For example, it has been shown that coffee has protective effects in the development of cancer, especially liver cancer. This is proven by a study from Italy. The researchers had evaluated ten studies and discovered that coffee drinkers were less likely to develop liver cancer. "Nevertheless, one should not now believe that coffee can be drunk to prevent cancer. After all, it doesn’t depend on a particular food whether you get cancer or not", explains Faustmann.
Three cups of coffee curb liver disease
Coffee is also good for people with liver problems. This was the result of a study by the American National Cancer Institute (NCI) on patients for whom conventional therapy did not work. For example, the consumption of coffee in people with chronic hepatitis C and advanced liver damage is said to stop the disease from getting worse. Participants who drank at least three cups of coffee a day were more than half less at risk of disease progression than non-coffee drinkers. The researchers did not observe any protective effects in tea drinkers, as they are in the specialist journal "Hepatology" write. "While we cannot rule out a number of other factors associated with coffee drinking, the results of our study suggest that coffee-consuming patients are at lower risk of the disease getting worse"says study leader Neal Freedman.

Plasticizers and flame retardants can lead to obesity and diabetes in humans, according to a study. This is based on a study by the British environmental organization ChemTrust on human exposure to synthetically produced chemicals, announced the Federation for the Environment and Nature Conservation (BUND).https://123helpme.me/argumentative-essay/ Plasticizers and flame retardants are found in plastic toys, electrical appliances, PVC floors and in the coating of food cans. Humans can absorb these chemicals through the air, skin or food.

Obesity due to hormonal pollutants
The literature study presented by ChemTrust, which summarizes almost 240 investigations, clearly shows that hormonal pollutants are also among the causes of obesity and diabetes, explained Sarah Hauser, chemistry expert at BUND. In test animals, exposure to chemicals such as bisphenol A in the womb led to later weight gain and increased insulin resistance.
Plasticizers are particularly harmful to children and pregnant women
Houses warned that there was a risk that people could have diabetes. The federal government must therefore ensure that the exposure to chemicals is reduced, especially by sensitive people such as children and pregnant women. "Plasticizers and bisphenol A must be replaced with safe alternatives"called houses.
Danger underestimated so far
Gilbert Schönfelder, a toxicologist at the Charité Berlin, said that diabetes and obesity rates had reached epidemic proportions worldwide. So far, the main causes are incorrect diet and lack of exercise. "However, new studies show that exposure to hormonal pollutants could have an important and previously underestimated part of this", explained Schönfelder. Therefore the precautionary measures would have to be expanded. Hormonally active chemicals should especially not get into the bodies of children, but neither should they get into those of adults.
Reproduction and brain development are also affected
So far, the hormonally acting bisphenol A has been primarily held responsible for infertility, damage to sexual development, and prostate and breast cancer. The controversial chemical works similarly to the female sex hormone estrogen and influences reproduction and brain development.
Around seven to eight million people in Germany suffer from diabetes – and the number is rising. The sequelae of the disease are particularly tricky. Around every third diabetic has problems with poor blood circulation in the legs. The consequences are infections and poorly healing wounds on the feet – in extreme cases, there is even the risk of amputation. The Association of German Internists (BDI) points this out. Here are eight things that diabetes should read about the "Diabetic foot" should know.

60,000 amputations a year
The diabetic foot – too "Diabetic foot syndrome" called – occurs especially with longstanding, poorly controlled diabetes. Nerves and blood vessels in the feet are damaged over the years. Circulatory problems occur, the feet tingle or feel numb. In addition, the immune system is weakened, so that even the smallest injuries or pressure points can lead to infections. The BDI estimates that around one million diabetics have an increased risk of open wounds on their feet, around a quarter of whom already have an open foot injury. If the injuries are treated too late, the inflammation spreads and there is a risk of amputation. According to the BDI, around 60,000 diabetics have to have a foot amputated each year.
Tingling and poorly healing wounds as warning signs
Type 2 diabetes in particular – so-called adult diabetes – is often discovered late. Many diabetics suffer from the first symptoms of a diabetic foot at the time of diagnosis. The first warning signs are noticeably dry skin on the feet, a tingling sensation or a numb feeling in the legs and feet as well as poorly healing wounds. Pain when walking – so-called intermittent claudication – are typical signs of circulatory disorders in the legs. Anyone who notices such symptoms should speak to their doctor about them and check their feet regularly for sores and pressure points.
Comfortable shoes and good foot care
In order to avoid serious foot damage, diabetics should pay special attention to their feet. Those affected should not only examine the toes, but also the spaces between the toes and the soles of the feet for pressure points, redness, cracks and wounds. Daily foot washing with lukewarm water and subsequent creaming with a fatty cream are just as much a part of foot care as careful removal of calluses. Nails should only be cut straight to prevent them from growing in. Comfortable, wide shoes that do not cause pressure points are also recommended. Without exception, every injury to the feet should be examined by a doctor.
People with diabetes may be able to monitor their blood sugar levels in the future with the help of fluorescent beads in their ears instead of a painful prick in their finger. Japanese researchers created the basis for this.

Blood sugar is measured by light
The researchers developed a dye that emits light when it comes into contact with sugar molecules. They built the dye into tiny plastic beads, which they injected under the skin of the auricles of mice. There the spheres emitted more or less light depending on the animals’ blood sugar level. This reaction can be easily detected with measuring devices through the skin on the ear, so that the method could in future make daily measurements of blood sugar much easier for diabetics. This is what the researchers around Hideaki Shibata from the University of Tokyo report in the journal "PNAS".
Advantage: blood sugar is measured continuously
So far, most diabetics measure their blood sugar by pricking a finger and putting a drop of blood on a test strip. This strip is then evaluated with a measuring device that shows the current blood sugar level. This measurement has to be repeated several times a day and can only show the sugar level at a specific point in time. With the newly developed beads, on the other hand, blood sugar could be measured continuously throughout the day without having to take blood.
Probes in the ear are harmless
In the experiment, the beads remained in the ears of the mice for 30 days. The researchers compared the intensity of the light emitted with the blood glucose values obtained using the conventional method from a drop of blood from the animals’ tails. The results showed that the light intensity allows a reliable statement to be made about blood sugar. The mini-probes did not affect the health of the mice.
Warning sign of hypoglycaemia
The researchers’ next goal is now to use the new technology to develop tiny measuring devices that can continuously monitor blood sugar levels. These could also give a warning signal if the blood sugar level is too high or too low, for example to prevent hypoglycaemia at night, according to the scientists.
Those who eat a lot of dairy products are less likely to get diabetes. Various studies have already shown this. Now US researchers have found out why: A certain fatty acid in milk lowers the risk of developing type 2 diabetes by 60 percent. The Boston scientists present their study in the journal “Annals of Internal Medicine”.

Fatty acid is only found in dairy products
The results of the research team led by Dariush Mozaffarian are based on the data of 3736 participants in a long-term study, the main aim of which was to research risk factors for cardiovascular diseases. As part of this study, however, the scientists also checked the subjects’ blood sugar and insulin levels in order to clarify signs of diabetes. In addition, the levels of various fatty acids in the blood were documented – including that of trans-palmitoleic acid. This fatty acid is not produced by the body itself, but only occurs in dairy products.
Also has a positive effect on cholesterol levels
When analyzing the data, the connection between the content of the milk component in the blood of the test subjects and other health factors was shown: the higher the fatty acid values, the more favorable the values for cholesterol, inflammation markers and insulin. What impressed the researchers most, however, was the lower rate of diabetes patients in the group with the highest level of trans-palmitoleic acid in the blood: “The difference was immense – almost three times as much,” says Mozaffarian.
Means in the fight against type 2 diabetes?
Further studies should now follow in order to substantiate the result, to examine the mechanism of action of the fatty acid and to sound out its potential for possible therapies against diabetes, say the scientists. They want to investigate whether the fatty acids in milk can also be used specifically as a means of combating type 2 diabetes.
