Why won't it remember my food?!

I am new to this, found the app on my phone and now am loving the website even more!! I am trying to figure out on my down time, how to add a bunch of food that I will usually eat and get it to save into "my food" memory. One place informed me to hit the "remember this" however I can't even find that button!!!?

Any input would be very much appreciate! Please and thank you! jo
