1) Will a blood test tell me everything (all minerals, vitamins, iron, calcium, protein, etc) and is there a specific name for this type of test?
I would talk to your doctor if you want the specifics. Urine and blood test is what they use to asses the state your body is in. These tests are pricy and sometimes a waste of money unless you live somewhere with free healthcare.
uMMA(urine Methylmalonic Acid) is the most accurate for Vitamin B12.
There isn't many Vitamins and Minerals. There will be no need to worry about it as long as you have them covered daily.
2) I live a bachelor lifestyle so when you say a big portion of veggies daily, are you going to the market, cutting them up, preparing them yourself? Or do you buy pre-packaged bag? And how do you cook them - i.e. stir fry, with pasta/rice, sauce, etc
Thanks for your help
Bachelor lifestyle means single or partying type where you have no time for cooking?
Yes to your question. I don't eat anything premade. The body deserves the best.
You can either boil the vegetables or get an electric steamer, steam them, then mix them with steamed/boiled rice. Adding legumes is another great option. Sliced mushrooms, cauliflower, bell peppers, broccoli, etc.. are options for vegetables.
You can saute/stir fry the foods however I prefer eating clean foods that aren't loaded with oils.
I recommend investing in a quality potato peeler like the KitchenAid Stainless Steel Euro Peeler
if you don't have one. It makes peeling carrots a breeze.
Since most of us work and if you do work, I recommend getting quality pyrex glass meal containers instead of the cheap plastic ones that need to be replaced all the time. You can make as many daily meals as you'd like. 3 big or 6 medium meals. Its up to you.
I'm just listing options. Remember that its up to you to find out what works for you. Don't be afraid to experiment and being creative with food.
