Eating by the Traffic Lights

What the heck is Traffic Light Eating? I asked the same question a few months ago when I came across the concept. It's really quite simple... Green Light foods can be eaten with wild abandon, Amber/Yellow Light foods should be minimized and Red Light foods... well, they should be avoided.

I kind of liked the little comment in the diagram at right: "Just like running red lights in the real world, you may be able to get away with it once in a while, but you wouldn't want to make a habit out of it." So true!

If we break it down a bit more...

Green Light Foods

These are unprocessed plant foods, as close to how nature made them as possible. Whole grains, beans, legumes, nuts, seeds, fruits, veggies, herbs and spices. Some green light diagrams also include eggs and lean meats in here, which is a bit confusing. Given how damaging animal protein can be to our bodies, I can see why they should be included in the yellow category.

Amber/Yellow Light Foods

These include a lot of processed foods, things like refined grains, burgers, fries, pancakes, hot dogs, pizza, sugary cereals, etc as well as unprocessed meats. This would also include dairy, eggs and meat and fish.

Red Light Foods

Here, we are into a lot of the oh-so-yummy things - soda, chocolate, chips, cookies, etc. and ultra-processed foods.

The thing that I noticed, as I reviewed different images of Traffic Light Foods is... things move around. As noted above... some plans have lean meat as a Green Light food while in others its an Amber Light food. Or burgers can be Amber or Red... Dairy moves around... Oil moves around... which really makes me wonder what Big Industry lobbies are behind these different schemes.

I found an article on The Washington Post that explains why Traffic Light Eating is not so black and white... or red and green. Which just makes me wonder if its a useful concept at all?

The image I've used above is from NutritionFacts.org, operated by Dr. Michael Greger (author of How not to Die and How not to Diet). He advocates eating whole food plant-based as much of the time as possible and dipping into the amber and red foods on occasion, but only if it helps to encourage eating the green light foods.

If sprinkling bacon bits on a salad helps you to eat the salad... then sprinkle away.

On the other hand... we made a choco-zucchini loaf the other day since we are starting to get buried under our super-productive zucchini plants. Flour, sugar, oil, cocoa powder and more than a cup of chocolate chips helped us to eat one cup of shredded zucchini. In this case... I'm not sure that eating all that red light stuff is helpful in promoting the consumption of one cup of zucchini... Greger has also published a short (7 minute) video about how he sees traffic light eating, which makes a lot of sense...

Traffic Light Food Labels

But there is another form of traffic light food... looking at the actual sugar, fat, salt, calorie content of the food. I've seen this more in the UK... not so much in Canada yet... although it is coming! The idea is that current nutrition labels on food are confusing to the general public. Who really has time to figure out what is healthy and not so healthy on a nutrition label... but... add in colours and put a summary on the front of the package and... it becomes much easier to figure out what is healthy and what is not.

So in the label at right... half a package of the product has really high saturated fat, low sugar and is moderate for salt, fat and calories. I would say... not a great food.

But then... who determines what is low, medium or high? I came across this chart from the UK which outlines how much fat, saturated fat, sugar and salt qualifies as low, medium or high.

But... me thinks that this is really only going to be applicable to processed foods... which, in general... are either Amber or Red Light foods to begin with. Sooo... is this helpful or not?

I mean... if I want a Kit-Kat... is a label like the one below really going to stop me? I guess.... maybe... If I have one once a week... That little two-finger Kit-Kat has that much saturated fat? What does a regular Kit-Kat have!!?

And then... we have something like this oh-so-yummy Starbucks Double Chocolate Chunk Brownie - pure decadent deliciousness... Starbucks has nutrition information on their site... but just a bunch of numbers... I know that 9 grams of saturated fat is probably in the red category (judging by the Kit-Kat numbers above)... But what about the rest? How does it fall in the grand traffic-light food labeling scheme? Sigh... As I feared... red light for Fat, Saturated Fat, Sugar and... yellow light for Salt (200mg Sodium = 0.55 grams of Salt). Luckily, I only have one of these a week but still... If I had to barrel past all those red lights every time I ordered one... I might reconsider it.

I decided to play around in Publisher and...created my own Traffic Light food label for a Starbucks brownie... if I saw this every time I ordered one... would I still order one every week?

It's a good question... In the UK, they seem to believe that front of label packaging helps people make healthier food choices... and... this might be the case here too... I'm going to guess that all whole food, plant-based items will get green lights across the board... the question will be... what will meat, dairy, egg and processed food packaging look like? Can't wait to see!
