Due to the sudden deterioration in my mum's physical & mental health and also due to struggling to come to terms with her having to spend the rest of her life in a nursing home (not the happiest of places), my diet went completely to pot.
I "went off" salmon, sardines & powdered linseeds and started to eat carbohydrate/fat-based comfort foods. A black cloud slowly descended over me. I lost the motivation to do anything, including updating this blog. I also slept a lot. This continued for several months.
Then, for no apparent reason, a few weeks ago I got an urge to eat smoked salmon. I added 200g of smoked salmon twice a week back into my diet and after a few weeks, the black cloud started to lift.
Before I started supplementing with Vitamin D3, I used to eat lots of oily fish but did not function correctly mentally. This time, my Vitamin D3 status was good (I never stopped taking supplements even when I had the black cloud over me) but my EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) intakes were near zero.
In conclusion, it would appear that my brain needs adequate Vitamin D3 and EPA and DHA (and magnesium) to function correctly.
I won't be blogging as much as I have been previously, as I've now dumped the vast majority of the nutritional knowledge within my brain into this blog. If I come across anything new, I'll post it here.
Finally, I've found the cheapest source yet of 5,000iu Vitamin D3 gelcaps.
