The average daily calorie intake in the US has increased by almost a third in 30 years, reaching 2,374 kilocalories.
The influence of bigger portion sizes and excessive snacking outweighs the shift towards high-calorie foods, say experts.
You heard it here first !!

| Ahhh ......... the good ol' days |
A team from the University of North Carolina analysed data from food surveys carried out in the seventies, eighties, nineties and the last decade. The surveys record all food and drink a person consumes over a 24-hour period. The average daily energy intake of a US citizen increased from 1,803 kcal in 1977-78 to 2,374 kcal in 2003-06. In the last decade of the study alone, the average daily calorie intake went up by 229 kcal.
This study also looked at portion size and studies have shown that having larger portions of food leads to an increased intake.
Who'd have thought ?
