If you're asking this question than I suspect you already know the answer. I personally wouldn't recommend anyone eat honeycomb cereal. It will increase your blood sugar and cause you to eat more unhealthy foods. I also don't recommend anything processed, because frankly we're not designed to eat it.
Peanut putter I have a totally different answer for. Organic pb if you don't have an allergy to peanuts can be a heart healthy snack because in fat nut fats are good for you. That being said I am not suggesting you eat a jar of pb instead try a table spoon spread on a celery stick or just eat it right off the spoon.
