Eat Protein & Veggies First for Healthy Blood Sugar

kabobNearly 30 million Americans are living with diabetes, putting them at a greater risk of heart disease, kidney disease, blindness, and even premature death. From previous studies we know that a healthy diet is critical to diabetes control and prevention, and now a new report published in the journal Diabetes Care takes that advice one step further.

In addition to eating the right foods, researchers at Weill Cornell Medical College have determined that the order in which we eat certain foods may impact blood sugar levels after eating—and that eating protein and veggies first (before carbohydrates) may help regulate insulin levels and in turn help keep blood sugar in check.

The small study looked at nearly a dozen morbidly obese adults with type 2 diabetes. After monitoring their food intake, it was discovered that post-meal blood glucose levels were significantly lower (by as much as 29%) up to two hours after eating when protein and vegetables were consumed before carbs.

Because starchy carbohydrates break down into sugar in the body and can cause sharp spikes in blood sugar, study author Louis Aronne believes this simple step may be a helpful way for diabetics to manage their blood sugar levels throughout the day. Ideally, health experts agree that a diet low in carbs, sugar, and grains and high in non-starchy vegetables, low-sugar fruits, protein, fermented foods, and healthy fats is the most beneficial.

Study Uncovers Link between Parkinson’s and Gut Bacteria

hands_on_caneEvery day scientists find new reasons for us to be good to our gut bacteria. There are more than 100 trillion bacterial cells living and working in the human body (vastly outnumbering our human cells) and if those microbes are unhealthy or out of balance it can impact our well-being. Just recently, researchers in Finland discovered that people with Parkinson’s disease have distinctly different gut bacteria*—and finding out more may one day help with treatment.

Parkinson’s disease affects nearly 1 million people in the United States and close to 4 million people across the globe. The progressive disorder affects the central nervous system and typically comes on later in life, but as of now there is no cure. Parkinson’s causes problems with motor function, and symptoms included trembling, loss of balance, changes in speech, and muscle stiffness.

For this study, scientists looked at nearly 150 men and women, half of whom have Parkinson’s while the others were considered “healthy controls”. When they analyzed the gut bacteria of both groups, they found fewer bacteria from the Prevotellaceae family in the Parkinson’s group as well as large numbers of Enterobacteriaceae bacteria, which appeared to be associated with more severe symptoms. For example, walking and maintaining balance were notably more difficult in patients with higher levels of these bacteria.

These clear differences in gut bacteria intrigued researchers, especially since gastrointestinal problems—mainly constipation—are often seen in the early stages of Parkinson’s disease, before the more pronounced motor symptoms begin to manifest. And, because gut bacteria interact so closely with the nervous system, scientists wonder if altering the bacterial environment in the gut may one day help protect against the disease.

Lead author Dr. Filip Scheperjans and his team plan to continue studying the same group of patients to further examine the link between gut health and Parkinson’s disease. They hope to determine whether or not the differences in gut bacteria are there even before the onset of the disease—like a marker—and if they change as the disease advances. The answers may one day help doctors improve the diagnosis and treatment of Parkinson’s disease.
