Brain Scans Suggest ‘Food Addiction’ Might Be Real

A new study published in the American Journal of Clinical Nutrition studied the “truth” behind “food addiction”. Researches have enrolled 12 men, who were either overweight or obese. Participants were assigned to a two milkshake “meal” that had the same amount of calorie, taste and sweetness. However one had a high glycemic index carbohydrates (HGIC), and the other one had low glycemic index carbohydrates (LGIC). The study used MRI assessing a four hour postprandial brain activity, in addition to blood sugar and hunger levels. Results revealed that HGIC such as white bread, seem to activate neurological centers focused on cravings and reward, a center that is also known for addiction. How surprised are you by the results of this research?

How the Taste of Food Is Affected By the Weight, Size, Shape, And Colour of The Cutlery Used To Eat It

A recent study published in Flavour Journal, evaluated the influence of visual and proprioceptive effect on perception of food’s taste and flavor. More than a hundred students participated in this study. Plastic cutlery of varying shapes, colors, sizes and weights along with toothpicks were used in this study. The study compared the impact of this cutlery variation on participant’s ratings of sweetness, saltiness, overall tastiness and value. Results showed that light spoons, are preferred for a denser taste of yoghurt, darker colored spoons intensified the sweet taste of yoghurt and finally cheese was found to be saltier when tasted with a knife rather than a spoon, fork or toothpick.Would you consider using these findings to enhance the taste of your food?

The First Randomized Controlled Trial, Studying The Efficiency and Safety Of E-cigarettes.

Since they were first introduced in 2004, questions were raised about their safety and actual effectiveness in quitting the habit of smoking. A recent study, published in Plos One, assessed the use of electronic cigarettes instead of regular ones in Italian subjects who were not willing to quit. A total of 300 subjects were enrolled and were evaluated throughout a whole year. The study analyzed the use of E-cigarettes with three different strengths of nicotine (7.2mg, 5.4mg and placebo) in three different groups. Results concluded that there was a significant decrease in the number of cig/day used in all three groups and up to 13 percent of these subjects quit smoking a year later. What are your thoughts on this? Would this study encourage you to recommend your smoker patients to switch to E-cigarettes?For more detailed information on this study, please click here

Keep fruit and vegetables in daylight to boost nutrients

Current Biology published a study regarding the best way to store fruits and vegetables to obtain the most benefit. The study found fruits and vegetables follow a 24-hour plant clock. Food crops can alter the internal chemical level throughout the day in order to ward off pests. Storing fruits and vegetables under the light-dark cycles helps them to preserve more nutrients. Glucosinates, a chemical with anti-cancer property is produced by cabbage in the day; refrigerated cabbage on the opposite produced less glucosinates. Further tests revealed many other crops (e.g., lettuce, spinach, courgettes, sweet potatoes, carrots and blueberries) also follow the same light-dark cycle. Please share your thoughts on the result of this study. How do you typically store your fruits or vegetables?
