Why Does Michael Crawford Say DHA Is More Important Than DNA?

TL;DR

DHA may be more important than DNA because, according to Michael Crawford’s 2012 paper, its exceptional conservation in electrical signaling membranes suggests that DHA influenced DNA rather than the reverse. DHA forms a key part of photoreceptor, synaptic, and neuronal membranes, while supporting brain development and neurogenesis. Read on to see how Crawford connects this fatty acid to vision, pregnancy, circadian rhythms, and neural signaling.

Questions & Answers

Q: Why does Michael Crawford suggest DHA is more important than DNA?

Crawford argues that DHA remained extremely conserved in electrical signaling membranes despite major genomic change. His 2012 paper says this pattern suggests DHA was dictating to DNA rather than DNA dictating to DHA.

Q: What role does DHA play in the brain and nervous system?

DHA is a principal component of synaptic and neuronal signaling membranes. According to the transcript, it helps generate electrostatic potential across neuronal lipid bilayers and supports fast communication between neurons.

Q: How does DHA contribute to vision?

DHA provides the core of photoreceptor membranes that convert photons into electrical signals. The transcript says the eye contains 91 million rods and 4.5 million cones with DHA-loaded membranes, and that 93% of the fatty acids in the retina are DHA.

Q: Why is DHA especially important during pregnancy and infancy?

A developing baby depends on DHA because it is a component of neurons, eyes, the nervous system, and cellular membranes. DHA needs rise during the last trimester of pregnancy as the baby’s uptake reaches peak levels, while the baby’s brain can produce up to one million synapses each second.

Q: How does DHA support neurogenesis?

DHA can upregulate nerve growth factor, brain-derived neurotrophic factor, and synaptomide, which participate in neurogenesis. This process helps neurons repair themselves, strengthen connections with other neurons, and stimulate the production of new neurons.

Q: What cognitive benefits are associated with adequate DHA?

The transcript says studies have shown that adequate DHA can improve IQ scores. It connects this effect with DHA’s support for neurogenesis, neuronal connections, and communication within the brain and nervous system.

Q: How does DHA relate to circadian rhythm and melatonin production?

DHA supports the healthy expression of genes related to the hypothalamus and suprachiasmatic nucleus, which regulates hormones alongside cycles of light and darkness. Healthy DHA levels are also correlated with proper pineal gland function and healthy melatonin production.

Q: What quantum properties did Crawford propose for DHA?

Crawford proposed that pi electrons might move through DHA by quantum tunneling and that DHA could have properties resembling semiconductors. His paper suggests that precisely quantized signaling could contribute to clear vision, reading acuity, fine motor skills, three-dimensional vision, and smooth mental processes.

Summary & Key Takeaways

• DHA, an omega-3 fatty acid, plays a crucial role in brain and nervous system development, influencing electrical signaling in various cells throughout the human body.

• Research by Dr. Michael Crawford emphasizes that DHA has remained practically unchanged over millions of years, highlighting its energy efficiency and essential contribution to photoreception and neuron dynamics.

• Adequate DHA intake is vital during pregnancy and infancy for optimal brain growth, neurogenesis, and cognitive abilities, yet many people are deficient in this essential fatty acid.
