Even though I have been vegetarian for 12 years, I ate heavy, rich meats for 28 years. I think seasons of change best fits my psychological profile. It is interesting how many of us look for that "thing" that works, in fact always works, and we find our justifications for believing it, whether it be scientific, yogic or biblical, holistic or moral. Nothing processes the same way all the time in the body throughout one's life, but I feel that some of our scientific methodologies or otherwise can give a roundabout, general explanation.
For example, Lactose free milk
is working quite well for me right now, and I decided to become gluten-free and stop eating wheat and soy
products (soy meats and soymilk were a huge staple). In two weeks, it's quite possible
that my body says "okay you are done for the moment with that." At
which point, I will probably switch to an almond milk or none at all, as
I may not be able to justify drinking the sugar content.
From a yogic
and ayurvedic perspective, it is on point for me to consume these
products to balance and soothe my pitta influence, and is also very
grounding to me at a time when I'm dealing with many ungrounding, strong
forces. I blather on. I feel that our bodies can
basically consume anything it adapts to, and there are studies that
support it. There are also studies that support the noncomsumption for
reasons above that yoga eloquently mentions. This is why sometimes I
wished I could go back to not knowing, because I made all of my best
food choices when I could just go on intuitive feel, and decided when
something was right or not for me to consume. My two cents. Namaste.
