This week’s blog has links to some interesting studies that could impact your health or the health of someone you know.

 

Certain gut bacteria may induce adverse changes to one’s metabolism following the consumption of artificial sweeteners

Artificial sweeteners are promoted as aids to weight loss and diabetes prevention. Research shows these could actually hasten the development of glucose intolerance and metabolic disease, by changing the composition and function of the gut microbiota

Wine only protects against cardiovascular disease in people who exercise

Moderate consumption of wine, defined as 0.2 L for women and 0.3 L for men, a maximum of five times a week, when combined with regular exercise,  improves markers of atherosclerosis, suggesting that this combination is protective against cardiovascular disease.

Fruit and vegetable consumption could be as good for your mental as your physical health

New research focused on mental wellbeing found that high and low mental wellbeing were consistently associated with an individual’s fruit and vegetable consumption. 33.5% of respondents with high mental wellbeing ate five or more portions of fruit and vegetables a day, compared with only 6.8% who ate less than one portion.

Comment: Many people turn to pharmacological aids to treat insomnia There are a number of effective alternative therapies, including botanical medicine, acupuncture and lifestyle modification, that can help with insomnia, most of which focus on the underlying cause.


Saccharin And Sugar May Be More Addictive Than Cocaine

The intense sweetness of saccharin and sugar can surpass cocaine reward, even in drug sensitized and addicted individuals.

The addictive potential of intense sweetness results from an inborn hypersensitivity to the taste of sweet.

The supranormal stimulation of these receptors by sugar-rich diets, such as those now widely available in modern societies, would generate a supranormal reward signal in the brain, with the potential to override self-control mechanisms and thus to lead to addiction.

Our ancestral environments were low in sugars and are thus not adapted to high concentrations of sugars and artificial sweetness prevalent in many of today’s processed foods.

HIIT- High Intensity Interval Training and Fat Loss. A better option

Aerobic exercise has some benefits, however. research examining High-Intensity Interval Training (HIIT) indicates that it may be more effective at reducing subcutaneous and abdominal body fat than other types of exercise.

Regular HIIT has been shown to significantly increase both aerobic and anaerobic fitness. It also significantly lowers insulin resistance and results in a number of skeletal muscle adaptations that result in enhanced skeletal muscle fat oxidation and improved glucose tolerance.

Comment: Steady state aerobic exercise is ineffective for weight loss and counterproductive as it breaks down metabolically active muscle. This seems to be a hard concept for most people to understand. The above study is one of many showing the effects of HIIT for weight loss. Other benefits include improved blood lipids and cholesterol as well as enhanced cardiovascular benefits.

 

Government agencies  need to assume greater role in regulating dietary supplements for weight loss, muscle building, experts say.

Dietary supplements, which are marketed to adults and adolescents for weight loss and muscle building, usually do not deliver promised results and can actually cause severe health issues, including death.

Because of lax federal oversight of these supplements, state governments need to increase their regulation of these products to protect consumers.

Comment: There are a number of supplements purported to aid in Weight loss and muscle building. I have had an interest in these topics for over 20 years, along with experience in the bodybuilding arena. This has led me down the path of numerous credential in exercise and nutrition.

In my experience, while there are a select few supplements that are evidence based, many are not.

The most effective way to achieve weight loss or build muscles, is through appropriate diet and exercise programming.
