Not sure where that previous comment was on nutrition..the only thing i would add is for carbs skip the grains(in the case of rice opt white rice since the bran in removed meaning lectins and phytic acids are not present) and go to starchy low fiber vegetables like potatoes, yuca, yada yada. Also tapioca flour has all the hyper-palatability of wheat flour but non of the damaging toxins of wheat and it tastes damn good.
Edit: I see it. I'd skip legumes so peanut butter as well(some of the same downsides of wheat pretty much) and if you get beans they need to be properly prepared via fermentation or sprouting. With nuts all you need to do is sprout them so some phytic acids are removed..
On olive oil make sure you are getting what you pay for: http://olivecenter.ucdavis.edu/news-events/news/files/olive%20oil%20final%20071410%20.pdf
Even some of the brands caught in fraud make usda certified organic evoo but I don't trust them since they are already selling a product that is not what it claims to be. They could be a mixture of vegetable oils like soybean or canola, which are unhealthy, which is why some people opt for evoo in the first place. A lot of people judge by the California Olive Oil council seal, in addition to the USDA one since many people find the regulations of the latter to be to relaxed. A rule of thumb would also be to look for glass bottles that are dark since light exposure oxidizes the oil and degrades the polyphenol content. So most things in clear plastic are wack.
Coconut oil, red palm oil, and pastured butter(butter from a pastured cow/read cow that eats grass and not grains and other ish), or butter in general but if you don't care to consume pasteurized factory farm milk like myself, you can make ghee from the regular butter and separate the milk solids from the actual fat..
Meats: pastured and grassfed are optimal, then organic would be next, a step down would be hormone free yada yada, last would be the regular stuff.
Fish is more tricky since their can be incorrect labelling throughout the process of handling and shipping, leading the consumer to purchase a product that is something other than what they believe themselves to be buying. Avoid farmed salmon like heck and try to get wild caught as often as possible. It can be expensive, though John West makes good canned wild salmon as some other brands do.
