Summary
Chris Masterjohn shares evidence-based strategies for enhancing cognitive performance through nutrition and lifestyle rather than pharmaceuticals. He covers key nutrients, dietary patterns, and habits that support optimal brain function.
Key Points
- Nutritional strategies can significantly enhance cognitive performance
- Key brain nutrients include choline, DHA, and B vitamins
- Blood sugar stability is critical for sustained mental performance
- Sleep quality directly impacts cognitive function and memory consolidation
- Specific dietary patterns support long-term brain health
Key Moments
If you have too much methylation, what happens is you break down the tonic dopamine, but not the phasic dopamine
tonic dopamine is your noise and when you are looking at the signal-to-noise ratio, you are looking at the degree to which the phasic pulse rises above the background noise of the tonic dopamine...
"But the low methylation people, the low CMT people, they had a massive increase in their amygdala lighting up. Why? Because they saw the unpleasant picture and they couldn't look at it and say, I don't want to think about that. They looked at it and they said, I cannot get that picture out of my head. This is distressing me. This is annoying me. This is hurting my feelings. And so the problem is not that they're more sensitive than the others. The problem is that they're not mentally flexible enough to let something go when they don't want to look at it. They see it once and it's stuck in their head."
These both show the importance of dietary glycine impacting the brain
Glycine has been used as an antipsychotic in schizophrenics at 60 grams a day and three grams of glycine before bed promotes sleep.
"Alright, now to demonstrate the population level importance of these things, MTHFR is an enzyme that uses B vitamins to support the methylation process. Low MTHFR activity will lead to low synthesis of creatine, low synthesis of acetylcholine, high tonic dopamine, high histamine, and loss of glycine in the urine. You know, if you don't have glycine, you're not going to sleep well. If you have high histamine, you're going to have high anxiety. If you have high tonic dopamine, thoughts are going to get stuck in your head. If you have low acetylcholine, you're not going to be able to focus and get sustained attention or form memories."
many other nutrients are important in methylation and the dopamine norepinephrine system
many other nutrients are important in methylation and the dopamine norepinephrine system. So dopamine is synthesized from the amino acid tyrosine which is obtained from protein foods using zinc,...
"Ultimately, improving energy metabolism to the fullest requires nutritional optimization around rare genetic bottlenecks. There's approximately 750 nutritionally actionable genetic disorders in energy metabolism that hurt the availability of ATP, which is needed to fuel methylation and is needed to regulate neurotransmitters with a distribution of about one to six per person. I said before 1,451, that's the total. Roughly 750 is the number that are highly nutritionally actionable, meaning you can do something about it with nutrition."
