I think meal preparation and recipe swapping steps just outside the nutrition scope of this site. But let's not get too crazy. You don't want to create moratorium against discussions about proper food selections on a nutrition site.
Obviously any discussion about nutrition will involve food choices but I would keep those discussions more about actual food choices (nutrition, on topic) and less about preparation and presentation (culinary talk, off topic).
For example:
- My stomach cannot handle citrus fruits but where else can I get my Vitamin C? — On topic
- Doctor said eat more bananas. How can I make them more palatable? — Right on that edge, off topic
- What is your favorite tofu recipe? — Definitely off topic
A big part of nutrition and fitness is menu choices for for whatever issue is being discussed. That's okay for this site. For example, one might answer:
As a weightlifter, you have to get more protein in your diet. Here is a sample menu:
Meal 1: 6:45 am
1 cup oatmeal
12 egg whites
1 whole egg
1/2 large grapefruit
Meal 2: 9:30 am 1 cup oatmeal 2 scoops vanilla protein powder (or 12 egg whites) 1/2 large grapefruit (etc.)
This isn't a cooking site (our Cooking site doesn't allow recipe-swapping either <grin>). But let's not jump on every user who asks about "what are good foods for [X] situation?"
