To reverse prediabetes, you don't need to lose fat, just shift it

Individuals with prediabetes, which involves elevated blood glucose (sugar) levels that do not meet the criteria for a diabetes diagnosis, are at a very high risk of progressing to diabetes. Clinical guidelines for delaying and preventing type 2 diabetes in individuals with prediabetes emphasize the importance of weight loss using lifestyle interventions or medications. A recent study showed that lifestyle interventions could lead to the normalization of glucose regulation in the absence of weight loss, and such a reversal of prediabetes was sufficient to reduce future risk of type 2 diabetes. These results suggest that clinical guidelines for type 2 diabetes prevention should also focus on normalizing blood glucose control in addition to achieving weight loss targets.

The key to mangoes’ better results likely lies in their being a whole food with natural fiber, vitamins, and nutrients. However, experts agree that the best way to avoid type 2 diabetes is to eat a balanced, healthy diet and be physically active, rather than to depend on a single ‘superfood’ to prevent the condition.

Drinking coffee in moderation linked to lower diabetes, heart disease risk

A new study suggests that moderate consumption of coffee and caffeine on a regular basis could be beneficial to prevent diseases like type 2 diabetes, coronary heart disease, and stroke. Compared with people who did not consume caffeine at all or very little per day, people who drank 3 coffee drinks per day or 200 to 300 milligrams (mg) of caffeine a day had a 48.1% or 40.7% reduced risk for new-onset cardiometabolic multimorbidity. Experts tout many of the other beneficial properties in tea and coffee but warn that other caffeinated beverages may not have the same benefits — and that there is no causal relationship between prevention of cardiometabolic multimorbidity and caffeine.

How might fat distribution in the body influence cancer risk?

Overweight and obesity are known risk factors for several types of cancer, including those affecting the breast, bowel and liver. But new research suggests that, for some obesity-related cancers, where fat is carried on the body may be as important as how much of it there is. The researchers propose that a better understanding of how fat distribution across the body affects cancer risk could help identify those most at risk of developing many cancers.

Rheumatoid arthritis silently starts years before pain, study finds

Rheumatoid arthritis is a chronic autoimmune condition that cannot be cured but can be treated to prevent its progression. Individuals at risk of developing rheumatoid arthritis can be identified 3-5 years prior to symptom onset based on autoantibody levels, but only 30-60% of individuals expressing these autoantibodies develop this condition. A recent study has identified changes in the immune profile or signature of individuals at risk for developing rheumatoid arthritis as they progress in the disease. These findings could help with detecting rheumatoid arthritis early and developing more effective preemptive therapies.

Keto may aid weight loss but lead to high cholesterol, mouse study suggests

Ketogenic diets that provide most of the daily calorie intake from fats have gained considerable attention as a lifestyle intervention for managing obesity and diabetes. Despite its popularity and effectiveness in promoting short-term weight loss, some human and animal studies suggest an adverse impact of a keto diet on metabolic health. A new long-term study conducted in mice now shows that a keto diet causes an increase in blood lipid (fat) levels, excessive fat storage in the liver, and impaired glucose regulation. These results raise concerns about the use of a keto diet for the management of obesity and diabetes and underscore the need for a cautionary approach.

As the popularity of GLP-1 medications used for weight loss continues to increase, more research is being done to further examine potential side effects of these medications. One such side effect is possible eye issues and vision loss, for which there is currently a great deal of conflicting information. Some studies link GLP-1 use to an increased risk for ocular diseases such as nonarteritic anterior ischemic optic neuropathy (NAION), diabetic retinopathy, papillitis, and optic nerve disorders. A new study reports that using semaglutide is not associated with an increased risk for eye disorders or diabetic retinopathy. While this new study found a connection between semaglutide use and NAION, researchers say that the current evidence is insufficient to establish a definitive connection between the two.

Inflammatory diets, ultra-processed foods may increase Crohn's disease risk

Inflammatory bowel disease (IBD) is a group of chronic conditions that damage the intestines and can cause uncomfortable symptoms. Preventing IBD remains a challenge, and research is underway to minimize this risk. A recent systematic review and meta-analyses identified dietary choices that may affect risk for Crohn’s disease, a major type of IBD. The study saw benefits from a Mediterranean-style diet and increased risk from diets containing inflammatory and ultraprocessed foods.

High amounts of ultra-processed foods may increase lung cancer risk by 41%

As the proportion of ultra-processed foods (UPFs) in the Western diet increases, concerns are growing about their health effects. Studies have linked UPFs with many health conditions, including obesity, type 2 diabetes, cardiovascular disease, and several types of cancer. Now, a study suggests that high consumption of UPFs could increase a person’s chance of developing lung cancer. While observing a link, the study cannot prove that UPFs cause lung cancer, but highlights a need for further studies.

Why are colorectal, other GI cancers on the rise in younger people?

Why are colorectal, other GI cancers on the rise in younger people?

Increasing age is the greatest risk factor for all types of cancer, with most cases being diagnosed in people over the age of 60. However, in people under 50, there has been a rapid, worldwide increase in cancers of the digestive system, or gastrointestinal cancers. Although still far less common than in older people, early-onset colorectal cancer is now the leading cause of cancer-related deaths in men, and the second in women, in the United States. The exact cause is unknown, but the authors of a new review published in the British Journal of Surgery suggest that obesity, a Western-style diet, nonalcoholic fatty liver disease, smoking, excessive alcohol use, and even exposure to microplastics, may all be contributing to the rise. Another study, published in Nature Medicine, has further estimated that, without early intervention, as many as 15.6 million gastric cancer cases may occur in the next few decades, most of which, are attributable to infection with a common bacterium, Helicobacter pylori.
