Mc Donalds is a restaurant where a lot of choices are available but some of it is junk food. It's quick though.
I'm not a huge fan of McDonalds. I prefer something like Chick-Fil-A
I do too actually.  Junk food is considered having high levels of calories with low levels of nutritional value.  
It's frustrating that it is more affordable to buy food that isn't really good for you.
I agree, we spend quite a bit on real food and I look at the cost of over processed junk and sigh.
Same. Our grocery bill went up significantly when trying to cut out filler foods and replace them with only healthy options.
And there are so many junk food options that are quick but I still prefer real food, even if it takes longer to fix.
Sometimes it's just easier to hit up a drive though. I agree, though. Making something from scratch always ends up being way more satisfying and healthier.
Have you heard of the fat tax which is supposed to help to decrease the number of purchases of junk food?
I haven't but that sounds like it could potentially be a good thing.
