According to number of observational studies and clinical trials carried out over approximately forty years, higher intake of fiber and whole grains (25–29g or more daily) is associated with lower risk of developing non-communicable diseases.
Non-communicable (or chronic) diseases are the conditions of long duration and normally slow progression. They include four types of diseases: cardiovascular (heart attacks and stroke), cancer, chronic respiratory diseases (chronic obstructed pulmonary disease and asthma), and diabetes.
Corresponding author Professor Jim Mann from the University of Otago, New Zealand, say: “Previous reviews and meta-analyses have usually examined a single indicator of carbohydrate quality and a limited number of diseases so it has not been possible to establish which foods to recommend for protecting against a range of conditions. Our findings provide convincing evidence for nutrition guidelines to focus on increasing dietary fibre and on replacing refined grains with whole grains. This reduces incidence risk and mortality from a broad range of important diseases.”
Anyone who ever tried to lose weight knows pretty well that it is impossible to lose fat only in one specific area. But there are certain methods that can help you to focus on a certain part of your body, belly fat in this case. Here are the six ways to lose belly fat proved by scientific studies:
Move as much as you can: run, bike, or swim.
Integrate more protein into your diet.
Eat more healthy fats such as olive oil.
Pay close attention to the quality of your sleep.
Increase the fiber intake.
6. Don’t forget about the balance of dieting and fitness.
Recent research, performed by Sara Seidelman, a cardiologist and nutrition researcher from Brigham and Women’s Hospital in Boston, USA, finds that diets which ban entire food groups from the eating plan, for example, ketogenic diet, may actually harm your health.
The research included eating patterns of more than 447,000 people from many countries around the globe. The analysis showed that popular keto diet that strictly limits intake of carbohydrates is one of the diets that may bring long-term harmful consequences. Other diets that should be included in this category are paleo diet, Atkins, Dukan, and whole 30.
Maciej Banach, a professor at the Medical University of Lodz in Poland who helped write the study, says: “Our study suggests that in the long-term, [low-carb diets] are linked with an increased risk of death from any cause, and deaths due to cardiovascular disease, cerebrovascular disease, and cancer.”
A new research, published in the Journal of Internal Medicine, finds that consuming more fish and long-chain omega-3s reduces total mortality. However, scientists insist that not all cooking methods are good for that matter.
For the study, a team of researchers performed an analysis of data from NIH-AARP Diet and Health study, which included information on the dietary habits and health of 240,729 men and 180,580 women followed for 16 years.
The authors conclude: “Consumption of fish and [omega-3s] was robustly associated with lower mortality from major causes. Our findings support current guidelines for fish consumption while advice on non-frying preparation methods is needed.”
A new study from Brazil suggests that trendy intermittent fasting may be the reason for increasing insulin levels and the amount of abdominal fat. It also may lead to the damage of pancreatic cells.
Intermittent fasting diet is a diet when a dieting person has “fast” days with a drastic restriction on calorie intake and “feast” days when one is allowed to eat anything.
For the study, a team of researchers placed healthy, adult rats on the diet for 3 months. During this period, scientists measured and monitored their insulin levels, function, body weight, and free radical levels.
At the end of the research, the rodents had lost weight according to expectations, but the distribution of their body fat changed unexpectedly — the amount of abdominal fat increased which is deeply associated with type 2 diabetes.
