I feel/felt like I was obsessing about what I ate but I didn't begin that way and certainly wasn't that way previously but after a long while reading info such as the following statements from this post for example, perhaps it is easier to see how a person can start to feel insecure about their food intake, wondering if they are getting it right and if it is a reasonable "diet" when there is so much to consider:
I kinda hesitate to recommend this book for anyone who may obsess about things, but Dr Gregers "How Not to Diet" is just stuffed with documented research on everything having to do with the diets of human beings. Our evolution, history, culture, genetics, environment, and the foods themselves. It also talks a lot about our psychological relationship with food
"...we have to make the conversion to DHA from proper ratios of omega 3 & 6 and I believe some 9"
"..Amino acids are not stored in the body. The individual amino acids are broken down into pyruvate, acetyl CoA, or intermediates of the Krebs cycle, and used for energy or for lipogenesis reactions to be stored as fats."
..."If you delve into the detail, protein when digested is broken down into amino acids. These amino acids are reconstituted again to create proteins when needed - for repairing or building muscle, for instance - but what isn't needed immediately to do this is denatured (i.e. the nitrogen removed and excreted as you mention) and then converted into carbohydrates and stored as glycogen."
.."In CronOmeter, I almost. always came out low on Magnesium and Potassium. So now I make a bigger effort to include potatoes I my diet"
Obviously, these are just a few examples of the info about vegan eating. I am playing devil's advocate here to some extent as I suspect deep down that there are really perhaps a handful or so of things to learn about a new way of eating and the rest is available for those that are looking for more detailed info or those interested in the science.
Something I am trying to get my head around is this: Can we just learn about vegan eating and then move on, never looking again at number crunching, or having to be concerned that we are getting enough of everything? That is what I want. I want it to be as easy as it was to eat (minus restaurant offerings of course ) before going vegan. If we are eating a varied vegan diet can we just leave it at that or do we, as vegans, need to be more aware of each of our nutritional requirements than a non-vegan would be?
