Sadly this is the case, I love the food giving stat concept, but content is so easy now a days, at best beginners benefit the most from it.
Clearly people (such as yourself that are 10k levels higher than me) won't benefit much. I don't have nearly all the life skills ranked for stats that I will someday, but if my guild asks me to contribute to harder content I can easily eat a sandwich and get the same dex as r5 weaving. Granted, I'll probably have to eat one every 10-15 minutes (but it doesn't add to weight, which is why that specific dish is perfect for me.)
