I've eaten differently at different times in my life. My mother was a health-conscious stay-at-home mom when my siblings and I were young, and we ate mostly home-made food and healthy foods until we were adolescents, when my mother took a job outside of the home.
After that, our family ate a more "typical" American diet, but still probably more balanced and healthy than a lot of families'. We hardly ever ate out or ordered in and we had minimal junk food in the house. We packed our lunches for school rather than buying them in the cafeteria.
Even though my siblings and I deviated from the healthy, balanced way of eating we had been raised on as we got older and gained more freedom, eventually we all went back to being generally healthy eaters. Much of that can likely be attributed to the fact that our mother taught us all how to cook, and we all enjoy cooking, so we don't like or rely on prepared foods or restaurant fare.
From my teenage years until recently, my diet was vegetarian or mostly vegetarian, and for a while closer to vegan. But I found that that diet wasn't ideal for my body. I developed various health issues from the lack of animal nutrients in my diet and my hereditary anemia was worsened by vegetarianism, regardless of taking vitamins and supplements.
After quitting vegetarianism altogether, my overall health has greatly improved. I'm actually eating fewer vegetables than I have in my entire life, but my body is thriving on the animal nutrients it was deprived of for so many years. I still enjoy vegetables, as I always have, but they no longer form the base of my diet.
The lesson I've learned from experimenting with different diets for optimal health is that intuitive eating and moderation works best for me. I eat "real", whole foods that are minimally processed for the most part, organic (when I think it makes a difference), and I eat more fat and protein, vegetables and fruit than I do grain, which I find that my body has a harder time processing.
For the most part I eat whatever I want, and I enjoy what I eat. My body knows what it needs and when it's had enough or too much of something, and its intuition has proven to be a more reliable guide than the advice of nutrition experts.
I try to honor God by taking care of His temple with what I put into it, which I believe is important, but I don't obsess over what I eat. Moderation, and listening to one's own body, is key to good nutrition.
