When it comes to food, healthy recipe and healthy cooking go hand in hand. Unfortunately, this is one area where there is a lot of misinformation and, due to the vast amount of it, we'll only be able to talk about a few of the challenges or myths. There's two issues to take care of and you can handle them both by looking for foods, recipes and information in different sources.
Thanks to busy lifestyles, food, healthy recipe and eating on the go seem to clash. This is an easy fix however, all you have to do is use fruit and vegetables on the go as a healthy snack. If you need a meal you turn it into a salad, grab something with protein and you're all set. This uses the principles of the raw food diet, while not to an extraordinary extent though, and you can learn about those benefits by researching raw food diets and recipes.
You can also begin to remove gluten and other allergens from food. You can find out tons in regards to being gluten free from experts like Antonio Valladares, organizations catering to those with Celiac disease (can't ingest gluten if you have this, so you'll find loads of information there), even resources focused on the correlation between diets and moods will provide information on food, healthy recipe ideas to get you started and a lot more.
Don't make the mistake and think you don't have food allergies. Don't make a mistake and look for low fat and low calorie this and that. Instead, find the healthy recipes from sources I mentioned and you'll then have the healthy cooking part taken care of. Tip: cooking in butter is okay; certain oils are okay, etc. so don't assume you know healthy cooking.
