So, if you get more polyunsaturated fats, you need more A, right?
And if you get more A, you need more D? What's the right balance?
And you don't want any of them to be synthetic.
So, I feel like we're getting plenty of A. Pretty much all the fats that we eat are Omega 6:3 balanced, and most are low in polyunsaturated fats period. Besides fish and flax seed, we basically just have fat from pastured meat, olive oil, and coconut oil. Does that mean that our need for Vitamin A is lower than people eating more vegetable oils?
I'm not sure how much I need to have CLO or other fish oil in order to balance omega 3's. We eat a good amount of fish, especially salmon, and make sushi once a week. I'm mostly concerned about the vitamins. It seems like Vitamin A is represented very well in the TF diet. Vitamin D seems harder to come by, and I don't know of sources of Vitamin D that do not also have a whole lot more Vitamin A. I'm just trying to figure out if this is a problem, especially with all the research coming out on the importance of Vitamin D.
We're entering winter here, and I've heard conflicting reports about whether or not it's possible to get enough Vitamin D here year-round. I try to make sure we get outside around noon every day, but in the winter, it's so cold, that even if we do get outside then, we have to be so well covered that not much of our bodies can be exposed to the sun, so I am concerned about our ability to get enough Vitamin D. We just had our first cold of the season, and it lasted over a week.
I know we should really just go get our Vitamin D levels tested, but I'm also looking at how to get more D. Are there any foods that contain a lot of D but not a lot of A as well? I'm also looking at supplements. I talked to somebody from Carlson's on the phone, and she said that the D drops that they have are sourced from lanolin. The "precursors" to vitamin D are "extracted" from the lanolin, so it is "lanolin free." Then they "add a methyl group" and "expose it to energy" to convert it to vitamin D. She stressed that this is basically how our skin works to convert sunlight to Vitamin D in our bodies and stated that "it's completely safe, as long as you don't give your baby too much." I'm not sure how I feel about this. What do you think?
