YSK there is a website where you can search on foods based on calories per gram and you can even narrow it down to specific nutrients. It’s incredibly useful if you are trying to fill out your micronutrients and don’t know what to eat. Instructions in comments.

edit – if you can’t reach the website right now try back later, I’ve found in the past that it can’t handle much traffic.

For example, if you want to find high volume foods based on calorie density per gram of food:

Select “lowest in…calories” from second drop down and then “based on levels per 100 gram” on other drop down and also narrow your food categories on the last drop down.

And you could narrow that down even further to foods with a specific nutrient, say for example, foods high in selenium. Use the top drop down for “highest in” and pick selenium or some other essential mineral or vitamin. You could even select based on carbs, protein,fats. It’s kind of fun and really informative.

Wow! Thanks for posting!

Cronometer is also great for this, I used it for a while

Thank you so much!! 🙂
