Full spud ahead

Potassium is often overlooked in diets even though its intake is linked with lower blood pressure in adults. A new study by the US non-profit Alliance for Potato Research and Education has found that eating white potatoes adds potassium. For each additional calorie of white potatoes consumed, there was a 1.6 milligram increase in potassium intake among adult participants (aged 19 and above). The US recommended daily potassium intake is 3,500mg. A small (138 grams) plain, unpeeled baked potato provides 738mg of potassium
and 128 calories.
 

Go the extra mile

If you knew a double quarter-pound cheeseburger required about a two-hour brisk walk to burn off, would you order it? Texas Christian University researchers found that a menu displaying the minutes of brisk walking needed to burn food calories led to lower-calorie choices, compared with a menu displaying only calories. The study involved 300 men and women aged 18 to 30, with the menus including burgers, salad, fries, desserts, soda and water.
 

 

 

Get a grip on memory

Clenching your right fist may help form a stronger memory of an event or action, and clenching your left may help you recollect the memory later, finds research by Montclair State University in New Jersey published in the journal PLoS ONE. In the study, the group that clenched their right fist for 90 seconds when memorising a list of 72 words recalled them better than other non-clenching groups. The authors suggest that this effect may be because clenching a fist activates specific brain regions that are also associated with memory formation.
