Plenty of research supports the common-sense notion that a healthy lifestyle can prevent or treat many diseases. A diet high in fruits, veggies, whole grains, and plant protein and low in processed carbs, added sugars, saturated fats; regular physical activity; and emotional well-being are the potent treatments that can prevent the need for or even […]

A small study suggests that routine home testing of blood sugar may not improve control or quality of life. However, more and longer studies are needed to know whether the results apply to all individuals with type 2 diabetes.

While diet soda and other types of artificially sweetened drinks may not have calories, research is suggesting that those who drink them regularly may be at higher risk for stroke or dementia.

Considering the range and severity of health problems caused by diabetes, the focus on treating prediabetes in order to prevent it from becoming diabetes is sensible, and a large study found that it is possible. A healthy diet and adequate physical activity can help most people side step this condition. For some, medication is also necessary.

Data from surveys of 200,000 people spanning two decades add support to the belief that eating a diet made up largely of plant-based foods is likely to lower a person’s risk of developing diabetes.

There’s no sugar-coating it: All calories are not created equal

The view that calories are calories regardless of their source has been shown to be outdated. Foods with a low glycemic index are better because they tend to raise blood sugar more slowly, and they are also more likely to be healthier foods overall. By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.

The dangers of sepsis are more pronounced for certain parts of the population, and more likely to be caused by certain types of infections, like pneumonia. It’s vital that patients and those close to them be aware of the signs of sepsis and get immediate medical attention if it is suspected.

Excess sugar in the diet can cause a whole host of health problems, both physical and mental. If you’re concerned about cutting down on sugar, you might think you’re covered if you skip the soda and pastries. But there are plenty of hidden and added sugars lurking in all kinds of foods — even those traditionally considered “healthy.” Here, we’ve given you some tips on what to watch out for.

Diabetes drug pioglitazone could get personal: Neither panacea, nor peril

Doctors are often hesitant to prescribe newer drugs. We simply can’t know everything about them until the experiences of early adopters tell us what they’re really like. Such is the case with thiazolidinediones. Some of the more recent diabetes drugs fell out of favor, but a new study suggests that may be helpful for very specific types of patients.

Tight blood sugar control in type 2 diabetes linked to fewer heart attacks and strokes

Diabetes damages every part of the body, from the brain to the feet. High blood sugar, the hallmark of diabetes, wreaks havoc on blood vessels. It makes sense that keeping blood sugar under control should prevent diabetes-related damage — but how low to push blood sugar is an open question. A study published in The New England Journal of Medicine (NEJM) provides reassuring evidence that so-called tight blood sugar control is good for the heart and circulatory system. A 10-year follow-up of the Veterans Affairs Diabetes Trial showed that participants who aimed for tight blood sugar control had lower blood sugar and fewer heart attacks and strokes than participants whose blood sugar was allowed to float a bit higher. Although tight blood sugar control can help prevent diabetes-related damage, it can have drawbacks such as bouts of low blood sugar (hypoglycemia), which can be dangerous. Current guidelines from the American Diabetes Association recommend tight blood sugar control, but also recognize there’s no one-size-fits-all rule.
