If we find out through experimentation that we don't feel bad effects from eating gluten or dairy, why would they continue on our list of "evil" foods? Not everyone is sensitive to these food categories.
Technically, this is from a different diet plan, and my first thoughts when hearing about it were "ewww, yuck!" But it turned out to actually be pretty good: 1 part orange juice to 7 parts water. Not high calorie, not enough to spike your insulin even if you're sipping all day. It can be done with other juices as well, but the suggested ratios were different, depending on the amount of natural sugar in the juice. Oh, and it called for "not from concentrate" orange juice.
I am a nurse, answering this off the cuff, so I don't have a list of references for you. I'm new to daily burn, so I'm not writing this for them, just general fyi.
I don't believe Aspartame/Nutrasweet/Equal has been associated with cancer, but there are studies that show it may be related to neurological problems. It is associated as a migraine trigger for some people; I can attest to that one personally.
The main issue with artificial sweeteners is that they can trigger the craving for sweets just like sugar/carbs can. That makes it more difficult for someone who's trying to stay away from sugar to actually do so.
There is also a study out there that lists the effects of all sweeteners, including natural sweeteners, on the body. Honey was the best sweetener in terms of possible effects on the body, that blue agave stuff (natural?) was the worst. Sucralose and aspartame were not in the top half of the list.
I thought soy is off limits?
I thought milk is off limits?
