DO generally refers to the action itself, and MAKE usually implies that there is a result. For example, if you "make breakfast," the result is an omelet! If you "make a suggestion," you have created a recommendation.
Use DO for actions, obligations, and repetitive tasks:
do the laundry
do the shopping
do well / do badly (in general)
do the right thing
Use MAKE for creating or producing something, and for actions you choose to do:
make your own peanut butter
make money (= earn money)
make friends (= meet people and start friendships)
make a suggestion/comment/complaint/confession/excuse/promise
the last great food to eat for healthy eyes is sweet potatoes. Its the beta carotene you have to thank for helping to keep your eyes healthy when you eat sweet potatoes. I like sweet potatoes since they are very versatile. You can mash them, roast them, or even make them into chips and fries.
