Lately, I've been reading several articles about the national restaurant menu labeling legislation passed in March and the abundance of professional opportunities expected to arise in the upcoming months. Specifically, I'm referring to Section 4205 of H.R. 3590, the Patient Protection and Affordable Health Care Act, which mandates that restaurants and food vendors with more than 20 locations make calorie and nutrient information readily available to consumers. (What, you haven't read the whole bill?)
It's abundantly clear to me that menu calculations must be conducted by someone with both nutrition and culinary expertise. Let me provide an example:
Last week, I received nutrition information from a vendor to use in my calculations of a patient's food record (this vendor supplies certain types of meals to the hospital). Here's the info I was sent for one meal (fish and mixed vegetables):
350 calories
3.5g total fat
116.20 calories from fat
5.90g total carbohydrate
31.40g total protein
What's wrong with this picture? Well, let's start with the basics: fat has 9 calories per gram, protein and carbohydrate each have 4 calories per gram. Clearly, the item above must have more than 3.5g of fat if the fat is contributing 116.2 calories (116.2/9 = 12.9 g of total fat is more likely to be the case). However, if you multiply all the macronutrients (fat, carb, protein) by their calories, I still don't end up with 350 total calories:
