How to prepare food at home that isn't toxic:
1. Eat whole foods - when you buy an apple, you generally know what's in it as opposed to apple sauce, not so sure there.
2. Purchase fresh fruits and veggies from a known source that isn't using pesticides - Organic in the grocery - Or even better, grow your own!
3. Purchase meats that do not have nitrites, hormones, antibiotics, flavor enhancers etc., also understand what the animal ate will pass through to you. If a farmer uses feed for the animal containing pesticides, think that doesn't get into what's on your plate? Think again. If at all possible find a local rancher/farmer for your meats.
4. Go for grass fed beef, I know lots of folks like the extra marbling from corn-fed or corn-finished beef, but it is far healthier to avoid the corn.
5. Water is probably the healthiest liquid you can consume, but make sure you're not drinking junk water, I don't know that I would trust any sort of city water anymore, if you can get a filter to get all the chlorine and other chemicals, that would help. Preferably a whole house filtration system, since you're showering in this too.
6. OK, I totally get it, sometimes you're going to indulge, so when you do, you can indulge in a healthier way when you cook at home by using all clean ingredients, at least you're not getting preservatives and food coloring garbage in your treats, then the next step is to indulge lightly, don't binge the junk and then feel like crap physically, mentally and in your soul for eating the ENTIRE pie, invite people over to share in the dessert, then it won't be sitting in the kitchen taunting you to take another bite. You know, the sealed left-over pie that has the fork in it and you just pop by for a bite . . . . . . or 12!
