How fortunate they have such a good friend as you are. My son had good friends, too who brought groceries and cards, and visits. From some recovering from illness, I think it may be difficult to actually ask for specific help even when it is offered as you so graciously have. My son told me once that even though he had hesitated to ask for specific things beore, that the next time someone offered to help, he would tell them specifically what he needed and people were grateful they could do something. Perhaps it might be easier for your friends to accept help if you stated specifically what you might be available for such as asking if they needed errands run, picking up a prescription at drugstore, ordering and picking up a pizza, chinese food, babysitting (if they have children) loading dishwasher, renting a funny movie, cleaning the cat litter box (if they have a cat) doing some laundry, or anything else you might notice that needs doing. Or you might offer to make a list of things they need, cut strips with one job on each and place the "jobs" in a box that your friend or her husband could point to next time somebody says "Is there anything I can do?" That way if they don't like the one they pick, (like the kitty litter) they can pick a different one. You can start it by picking one of the items yourself. How about that?
