Low Carbohydrate Diets Reduce Inflammation
A state of chronic s
ystemic inflammation is one of the calling cards of disease. Having chronically high levels of inflammation can wreak havoc on the body, eventually leading to a whole host of ailments such as the destruction of joints and connective tissue and even heart disease. A new study conducted by Linkoping University has found that low carbohydrate, not low fat, diets reduce inflammation in people diagnosed with type-2 diabetes. For the study researchers took 61 individuals previously diagnosed with diabetes and randomly assigned them to either a low-fat or low-carbohydrate diet. Blood was drawn from each participant to assess blood glucose, and various inflammatory markers prior to beginning and at regular intervals during the study. Researchers found that after six months although weight loss was relatively the same, the low-carbohydrate group had significantly lower blood glucose levels in addition to a significant decrease in levels of inflammatory markers in the blood. Although it has been proven that wheat gluten causes increases in systemic inflammation, this study shows that general consumption of carbohydrates may be enough to cause inflammation.
High Intensity Exercise Controls Blood Sugar Better than Moderate Exercise
When it comes to cardi
o, most people seem to fall into one of two camps; those who believe either in high intensity, or those or believe in low-intensity steady state for fat loss. A new study published in the journal Diabetologia gives HIIT advocates a reason to rejoice, and may cause those who engage in traditional cardio to reconsider their approach. A study conducted by researchers at Otego, Dundin University in New Zealand has found that high intensity exercise thirty minutes before meals helps to better control blood glucose for up to 24 hours. Researchers had 7 healthy participants between the ages of 18-55 engage either a 30 minute session of moderate intensity exercise (walking on a treadmill), or a high intensity exercise session that consisted on 6 intense 1 minute bursts immediately followed by 1 minute of walking. Researchers found that the high intensity group had a 17% reduction in blood glucose after breakfast, and a 12% reduction in blood glucose levels over the course of the day. By reducing blood glucose levels, and keep insulin levels low, it allows the body to more effectively mobilize fatty acids and could result in accelerated fat loss.

Omega-3 M
olecule Mimics the Effects of Exercise
It’s no secret that exercise and omega-3 fatty acids are an effective method for helping to regulate blood sugar and increase glucose uptake. The ability of omega-3 fatty acids to help reduce insulin sensitivity has made it a popular supplement among diabetics looking for more natural ways to help manage the disease. According to a new study published in the journal Nature Medicine, Canadian scientists from The University of Laval in Quebec has isolated a compound in omega-3 fatty acids that has the ability to mimic the effect of exercise on the body. Researcher discovered the compound identified as protectin DX (PDX). When researcher issued PDX to two groups of mice, one of which served as the control while the other was engineered to develop type-2 diabetes, they found that the PDX stimulated an inflammatory marker known as IL-6 in diabetic mice. IL-6 is also found in the blood after exercise, and sends signals to the muscles to bring the glucose transport protein known as GLUT4 to the surface of cell. GLUT4 has the ability to clear glucose from the blood without the presence of insulin, and researchers believe that they may be able to develop a compound that will be able to exert the powerful effects of PDX on humans as a new alternative to diabetes treatment.
Resveratrol Does Not Reduce Cancer or Heart Disease
Resveratrol h
as made its way into a number homes due to its reported ability to be an exceptionally potent antioxidant. Resveratrol is a naturally occurring polyphenol that can be found in a number of healthful foods such as dark chocolate and in particular red wine. Although it’s been hailed as a wonder supplement, and a key to life extension, new research conducted by John’s Hopkins School of Medicine has found that it may not be as beneficial as once perceived. Researcher studied local residents in an Italian province that took little to no supplements, but consumed a liberal amount of red wine on a regular basis. They collected samples from adults over the age of 65 and analyzed them to determine the amount of resveratrol metabolites that were presents. After compiling the data, and cross referencing that with health records, researchers found that the amount of resveratrol present in the body had little to no impact on extending life, preventing cancer, or impeding the development of heart disease. Researchers do believe that the antioxidant benefits of resveratrol are beneficial, but also warn that the wild health claims associated with its use are little more than hyperbole.
High Level Athletes May Need Pacemakers as They Age

lding, just like any other sport, is not without its health risks. However, certain aspects of the sport do lend themselves to the development of health issues without proper monitoring on a regular basis. However, new research from The University of Manchester has found that men and women who were high level athletes early in life are more likely to need a pacemaker later in life according to a new study published in the journal Nature Communications. Although the resting heart rate of a normal individual is typically close to 100 bpm, high level athletes have been known to have resting heart rates as low as 30 bpm. Researchers found that body’s own internal pacemaker actually has its structure altered, which leads to difficulties in generating normal heart rhythms as we age. Although the research shows that cardiac function can be altered, they note that this is not an indictment on exercise. The benefits of regular exercise far outweigh the potential risk of developing irregular heart rhythms, and most individuals never reach a fitness level similar to that of elite athletes that would give them reason for concern.
