Recent studies show that grapefruit and diabetes may share a close link. Researchers concluded that naringenin found in grapefruit may increase the body's sensitivity to insulin. This research was conducted only in the laboratory, and further studies are still needed. Grapefruit and diabetes may share a close link given some recent studies suggesting that eating of the fruit can help in controlling the disease. One recent report suggests that grapefruit may become an effective part of the treatment for type 2 diabetes as it contains the antioxidant Naringenin that can break down fats and increase a person's sensitivity to insulin.
The study also concluded that grapefruit is also capable of treating abnormal levels of cholesterol, warding off metabolic syndrome and improving a person's tolerance to glucose, factors that are all associated with diabetes. The study was conducted by scientists from the Massachusetts General Hospital Center for Engineering in Medicine and Hebrew University of Jerusalem. Although more research needs to be completed, grapefruit is a safe source of vitamins for diabetics. One-half of a grapefruit contains 52 calories and 13g of carbohydrates, and the fruit has a low rating on the glycemic index, indicating a lower propensity to drive up blood sugar levels.
The antioxidant Naringenin is found in grapefruit and has been largely credited for its ability in heping to treat type 2 diabetes. Naringenin is specifically noted for being able to break down fatty acids in the liver, similar to what happens when a person undergoes fasting. Yaakov Nahmias, PhD of the Hebrew University of Jerusalem reports that the results of their study indicate that Naringenin antioxidant was found to be capable of breaking down fatty acids similar to those induced by significant amounts of fasting. It does so by activating nuclear receptors, a family of proteins that can cause the liver to break down fatty acids instead of storing them.
Another study conducted by researchers at the University of Western Ontario showed that Naringenin can correct increases in triglyceride and cholesterol levels, while resisting insulin resistance and normalizing glucose metabolism. The said study showed that Naringenin genetically reprograms the liver to burn up more excess fat, instead of storing it. The said study also showed that Naringenin is able to suppress appetite and decrease food intake, which are common strategies in controlling diabetes.
The study of MGH and Hebrew University scientists also noted that Naringenin can lower bad cholesterol called vLDL while able to cure several symptoms of type 2 diabetes.
Research on grapefruit and diabetes, however, has not yet been conducted on humans, and were only done in the laboratory on the liver cells of humans and rats. Until further studies are done to confirm the effects of grapefruit in the treatment of diabetes type 2 in humans, it is still not safe to conclude that the naringenin in grapefruits can indeed cure diabetes. Further studies are still needed to establish its efficacy as well as its overall effects in the body, including the negative effects it might have.
Thus, many health experts do not encourage patients with diabetes to increase their consumption of grapefruits or increase grape juice intake, especially if they are also taking medications. There are patients prescribed with some type of drugs to lower their cholesterol level who are advised not to drink grapefruit juice as it can increase risk of side effects.
Eating almonds could help prevent diabetes and heart disease, according to a study.
The research found incorporating the nuts into our diets may help treat type 2 diabetes, which accounts for 90 to 95 per cent of all cases.
As well as combating the condition, linked to obesity and physical inactivity, it could tackle cardiovascular disease, the report published in the Journal of the American College of Nutrition said.
Diabetes is one of the fastest growing diseases in the world, and sufferers have a shortage of insulin or a decreased ability to use the hormone that allows glucose (sugar) to enter cells and be converted to energy.
When diabetes is not controlled, glucose and fats remain in the blood and over time, damage vital organs.
The study found consuming a diet rich in almonds may help improve insulin sensitivity and decrease LDL-cholesterol levels in those with pre-diabetes, a condition in which people have blood glucose levels higher than normal but not high enough to be classified as diabetes.
Researchers looked at the effects of consuming an almond-enriched diet on 65 adults with pre-diabetes (48 women and 17 men) with an average age in the mid-50s.
The participants were split up, and the group on the almond-enriched diet showed greater improvements in insulin sensitivity and clinically significant reductions in LDL-cholesterol compared with the nut-free group.
Dr Michelle Wien, assistant research professor in nutrition at Loma Linda University's School of Public Health, said, “We have made great strides in chronic disease research from evidence of effective treatment to evidence of effective prevention.”
The principal researcher for the study, conducted at the University of Medicine and Dentistry of New Jersey, added, “It is promising for those with risk factors for chronic diseases, such as type 2 diabetes and cardiovascular disease, that dietary changes may help to improve factors that play a potential role in the disease development.”
An estimated 55 million people in Europe have been diagnosed with diabetes, and the figure is expected to rise to 66 million by 2030.
There is no known way to prevent type 1 diabetes, which may be autoimmune, genetic, or environmental. It accounts for five per cent of all cases. Type 2 diabetes most often occurs in people older than 40.
Around 60 million people in Europe have pre-diabetes. People with the condition have an increased risk of developing type 2 diabetes, heart disease and strokes.
Almonds are cholesterol-free and compared with other nuts, they are the highest in six essential nutrients – fibre, magnesium, protein, potassium, copper and vitamin E.
A GOURMET meal may be as bad for you as a Big Mac, according to diabetes researchers who are alarmed at the rise in young men diagnosed with the disease.Corporate lunches and dinners at restaurants dishing up rich, fatty foods, coupled with sedentary working lives are being blamed for the trend. Dr Neale Cohen, of the Baker IDI Heart and Diabetes Institute, said many patients were unaware meals at upmarket restaurants were often as high in fat, salt and sugar as fast food.
''Eating out is really code for eating badly,'' Dr Cohen said. ''Whether it's a fine French restaurant or McDonald's, it's the type of food that causes the problem.'' He said doctors at the institute are seeing men as young as 40 affected by type 2 diabetes, which is often triggered by obesity and linked to poor diet. ''Many of my patients will eat out three or four times a week for work and we are seeing 40-year-old businessmen who are in real trouble. To have diabetes at that age and otherwise be perfectly well with very little family history, is a really worrying thing.''
Dr Cohen recommends his patients only eat out once a week but said the ''MasterChef effect'' was encouraging people to re-create the elaborate dishes at home.
A new study has claimed that an ingredient of dark chocolate could assist in the control of severely high cholesterol levels, a major problem for those suffering from diabetes. Previous research has highlighted that chocolate which contains a high level of cocoa solids rich in polyphenols may be able to reduce the risk of heart disease, and this study, published in the journal Diabetic Medicine, saw a reduction in cholesterol for a small number of diabetics given chocolate that contained a lot of the chemical.
The researchers, from Hull University, examined 12 patients with type 2 diabetes who were given identical chocolate bars, some of which were enriched with polyphenols. The patients that consumed the enriched bars experienced a small improvement in their overall cholesterol rating, with a drop in total cholesterol while the level of good cholesterol increased.
Steve Atkin, who led the study, said “Chocolate with a high cocoa content should be included in the diet of individuals with type 2 diabetes as part of a sensible, balanced approach to diet and lifestyle.” However, the charity Diabetes UK warned that these findings may mislead people into eating too much chocolate, arguing that the high fat and sugar content probably outweighed any benefits.
Dr Iain Frame, director of research at Diabetes UK, commented “On no account should people take away the message from this study, conducted in only 12 people, that eating even a small amount of dark chocolate is going to help reduce their cholesterol levels.” He added “It would, however, be interesting to see if further research could find a way of testing whether polyphenols could be added to foods which weren’t high in sugar and saturated fat such as chocolate”.
Here is another reason to make the tasty almonds a part of your daily diet. The humble tidbit nuts that combine tons of essential nutrients in one delicious package are an effective weapon in fighting type 2 diabetes and cardiovascular diseases, claims a new study. According to researchers, almonds added to the diet have a favorable effect on blood cholesterol levels and insulin sensitivity, two vital risk factors that can trigger diabetes and heart problems.
Lead author of the study, Dr. Michelle Wien, Assistant Research Professor in Nutrition at Loma Linda University’s School of Public Health stated, “We have made great strides in chronic disease research from evidence of effective treatment to evidence of effective prevention. “It is promising for those with risk factors for chronic diseases, such as type 2 diabetes and cardiovascular disease, that dietary changes may help to improve factors that play a potential role in the disease development.”
In a bid to assess the impact of almond enriched diet as a prescription for physical wellness, the researchers conducted a study. The focus of the study was to analyze the effect of the humble nut on the progression of type 2 diabetes and cardiovascular disease. The investigators enrolled a group of 65 adults comprising 48 women and 17 men with pre-diabetes in their mid-50s. The study subjects were split into two groups. As a part of the study, one group was assigned to almonds while the second formed the control group. The control group followed a diet recommended by the American Diabetes Association (ADA).The group assigned to almonds conformed to a similar diet but also added 20 percent calories from almonds. All the participants were asked to consume the same amount of calories from carbohydrate-containing foods, such as pasta, bread, and rice. However, those consuming the almond-enriched diet reported a lower intake of carbohydrate-containing food items.
After a period of 16 weeks, the investigators compared the insulin and cholesterol levels of both the groups. It was noticed that people consuming almond-enriched diet exhibited marked improvement in their insulin sensitivity and a dramatic reduction in LDL cholesterol as opposed to those eating the nut-free regular diet.
The study was conducted at the University of Medicine and Dentistry of New Jersey. The findings of the research are published in the ‘Journal of the American College of Nutrition
The content of cholesterol and calories are pretty high in fast food is a cause of obesity and various metabolic disorders and heart. These impacts can be slightly reduced if balanced by drinking tea regularly.Obesity and metabolic disorders in people who are too frequently eat fast food due to the number of fat content and the use of oil in the food. While the threat to the heart is generally triggered by the use of salt, but also greatly affect cholesterol.
In a study conducted by experts from Kobe University, revealed that regular tea consumption may prevent damage to blood cells due to elevated levels of bad cholesterol. Consequently the risk for type 2 diabetes can be reduced.
A study published in the Journal of Agricultural and Food Chemistry that use 2 types of tea which is green tea and black tea. Both can memberikankan benefits, but black tea is said to be heart-protective effect. Benefits of tea that can be obtained according to these studies, among others, to prevent elevated levels of bad cholesterol, blood sugar and insulin resistance. The third condition is the main factor triggering type 2 diabetes caused by unhealthy eating patterns. “Drinking tea may help prevent obesity and blood fat levels settings. The problems are a result of high-fat diet,” says Dr. Carrie Ruxton of the Tea Advisory Panel as quoted from Dailymail, Sunday (19/12/2010).
Researchers from the University of Hull and the Hull York Medical School have found dark chocolate has a significant effect on reducing the symptoms of Chronic Fatigue Syndrome (CFS). The research, published in Nutrition Journal, found that polyphenol rich chocolate eases the condition, with subjects noting significant improvements to their well-being. Chocolate is known to increase neurotransmitters like phenyl ethylamine, serotonin, and anandamide in the brain, but this is the first time that polyphenol rich chocolate in people with CFS has been studied.
Above: Professor Steve Atkin.
Subjects with CFS having severe fatigue of at least 10 out of 11 on Chalder Fatigue Scale were enrolled on the pilot study. Participants were given one of two types of chocolate, one with a high cocoa content and the other without.
Over an eight week period the volunteers consumed one type of chocolate followed by a two week wash out period and then another eight weeks of eating the other variety. The dark chocolate contained 85% cocoa solids with the alternative containing none. Each individual bar weighed 15g with each volunteer expected to eat three per day, and also told not to consume more or make changes to their diet.
Researchers also noted the weight of subject did not significantly alter despite consuming an extra 245 calories per day for two months.
Professor Steve Atkin who led the study says: “The significance of the results is particularly surprising because of the small number of subjects in the study. A further study is needed to see what the effects would be on a larger group of people, but this is potentially very encouraging news for those who suffer from Chronic Fatigue Syndrome.”
This latest finding follows recent research also carried out at the University of Hull and the Hull York Medical School where dark chocolate was found to help reduce the risk of heart attacks in people with Type 2 diabetes by increasing the amount of good cholesterol in the blood stream.
Could the Mediterranean diet actually help prevent diabetes? The Mediterranean Diet, which is rich in vegetables, fruits, whole grains, healthy fats from nuts and olive oil, with moderate amounts of fish, low-fat dairy, and wine, and minimal red meat and processed meats, is considered to be an especially healthy eating plan.
Previous research conducted on newly diagnosed diabetic participants showed the diet did indeed help control the sugar spikes. The previous study found the mediterranean diet eating diabetics had better glycemic control. Furthermore, they had less needs for diabetes medications when adhering to the Mediterranean diet as opposed to a simple low-fat diet.
Recently, a team of researchers in Spain conducted a study using data from a large clinical trial to determine the effects of the Mediterranean Diet on preventing the onset of Type-2 diabetes. Participants were followed for an average of 4 years. Upon completion of the study, 54 participants had developed diabetes–but the split varied significantly among groups. The researchers found that the risk of developing diabetes was reduced by 52% among both groups of people who followed the Mediterranean Diet plans compared to the low-fat control group. In analyzing diet adherence, the researchers further noted that the closer an individual followed the Med-Diet plan, the lower their risk of developing diabetes. Interestingly, the weight of all participants did not change significantly throughout the study, nor did it vary significantly among the three groups.
The participants were divided in one of three groups: adherence to the Med-Diet with 1 liter per week of extra virgin olive oil, adherence to the Med-Diet with 1 oz per day of mixed nuts, or a standard low-fat diet as a control. No calorie restrictions were imposed on any of the groups. The two Med-Diet groups were instructed to increase fruit and vegetable intake, decrease meat intake, stay away from refined sweets and unhealthy fats such as butter, and consume red wine in moderation, if desired. The control group was given general instructions to lower overall fat intake. Baseline measurements and annual follow-up involved an oral glucose tolerance test and interviews to assess diet adherence.
Interestingly, the weight of all participants did not change significantly throughout the study, nor did it vary significantly among the three groups.
This study reinforces prior study results suggesting that the Mediterranean Diet – even without weight loss – may be protective against Type-2 diabetes. The researchers suggest that future studies should focus on the Med-Diet’s effects on younger people, and point out the possible benefits of the Mediterranean Diet as an effective intervention against complications of Type-2 diabetes.
A dietary supplement of the synthetic derivative of vitamin B1 has the potential to prevent heart disease caused by diabetes, according to new research from the University of Bristol, funded by Diabetes UK. Vitamin B1 may help the body to dispose of toxins and therefore protect cells of the heart from becoming damaged.
Diabetes leaves the heart more vulnerable to stress as less oxygen and nutrients are delivered to the heart and other organs. Heart damage can be caused by high levels of glucose entering cardiovascular cells, which forms toxins that accelerate the ageing of the cell. Around 50 per cent of people with diabetes die from cardiovascular disease, and this complication is the leading cause of death among people with diabetes. Researchers warn that with increasing prevalence of diabetes ( around one in twenty people in the UK are now diagnosed with the condition ), diabetes will result in a new epidemic of heart failure unless new treatments are developed.
A team of researchers at the University of Bristol gave a synthetic derivative of vitamin B1 called benfotiamine to mice with and without diabetes. They found that treating mice with Type 1 or Type 2 diabetes with benfotiamine from the early stages of diabetes can delay progression to heart failure. They also found that the vitamin B1 derivative improved survival and healing after heart attacks in Type 1 mice ( and even in the mice without diabetes too ). Foods rich in vitamin B1 include Marmite, yeast and quorn, but it is not yet known whether changes to diet alone would provide enough of the vitamin to see the same effects as supplements achieved in mice.
Previous Diabetes UK-funded research at the University of Warwick was the first to show that people with Type 1 and Type 2 diabetes have around 75 per cent lower levels of vitamin B1 than people without diabetes. It is thought that this may not be due to diet, but due to the rate at which the vitamin is cleared from the body. Small scale clinical trials of people with Type 2 diabetes have also discovered a link between taking vitamin B1 supplements and a reduction in the signs of kidney disease.
The latest research has been published in the Journal of Molecular and Cellular Cardiology. Professor Paolo Madeddu who led this research at the University of Bristol said “Supplementation with benfotiamine from early stages of diabetes improved the survival and healing of the hearts of diabetic mice that have had heart attacks, and helped prevent cardiovascular disease in mice with both Type 1 and Type 2 diabetes. We conclude that benfotiamine could be a novel treatment for people with diabetes, and the next step in this research will be testing whether similar effects are seen in humans.”
Dr Victoria King, Head of Research at Diabetes UK said “Diabetes UK is pleased to have supported this research and is encouraged by these promising results which now need to be tested and confirmed in human trials. We would like to note that it’s still too early to draw any firm conclusions about the role of vitamin B1 in the prevention of complications and we would not advise that people look to vitamin supplements to reduce their risk of cardiovascular complications at this stage. Taking your prescribed medication, eating a healthy balanced diet and taking regular physical activity are key to good diabetes management and therefore reducing your risk of diabetes associated complications.”
