The food label series:

Food labels are intended to help us make better decisions at the grocery store. But do they? In this 5-part series, Ryan Andrews and I will explore how food labels work and how to use them to make better eating decisions.

Food labels part 1:

In theory, food labels help us make informed – and, ideally, healthier – decisions. But does that hold true in practice? This first article in the 5-part series looks at why we label food, what’s on those labels, and where label information comes from.

Food labels part 2:

Manufacturers depend on consumers being rushed, busy, inattentive, and impulsive. Part 2 of our food label series examines the truthfulness, accuracy, and usefulness of label claims, and shares the most important information for you to know about a given product.

Food labels part 3:

In Part 3 of this article series, we look at back-of-package labeling: nutritional information and ingredients. In particular, we look at how calorie counts don’t accurately reflect how our bodies process food; and we challenge the classic “calorie math” of “energy in versus energy out”.

Food labels part 4:

Often we look for particular information, such as calories or fat content, on food labels, but don’t always interpret this information correctly. Or know how to apply it. Part 4 of our series on food labels looks at what consumers want (or think they want) on food labels, and how this affects their actual buying and eating behavior.

Food labels part 5:

However you choose the “baseline” that suits you, your nutritional level, and your own needs, what’s most important is that you are in charge of your food choices. To conclude this series, Part 5 will give you some tips and action steps to ensure you’re getting the most from your food labels.
