Start nutrition decisions by asking what the body needs to function, rather than beginning with a blacklist. Patrick describes amino acids, fatty acids, vitamins, and minerals as inputs for processes including energy production, neurotransmitter synthesis, and DNA repair. The method is to identify those inputs, choose complementary whole-food sources, and check measurable markers where useful. Leafy greens supply nutrients such as magnesium, vitamin K, and folate; meat and poultry add protein, iron, zinc, and B vitamins; seafood supplies omega-3 fatty acids. Only after this base is covered should someone optimize contaminants or exclusions. The mechanism is cumulative: adequate inputs support repair each day, whereas invisible shortfalls can allow damage and muscle loss to compound over decades.
Origin
Patrick connects this approach to her postdoctoral work with Dr Bruce Ames on micronutrients and the metabolic processes they enable.
Core principles
- 01Nutrition must supply the inputs required for metabolism and repair
- 02Avoidance alone cannot prevent nutrient shortfalls
- 03Micronutrient damage can accumulate without obvious daily symptoms
- 04A diverse whole-food diet covers complementary nutrient needs
How to run it
- 1
List essential inputs
Identify the nutrients your diet must supply, including protein, essential fatty acids, vitamins, and minerals. Treat them as operating inputs rather than optional enhancements.
Pro tip Start with common shortfalls Patrick discusses, such as magnesium and omega-3 fatty acids.
Watch out Do not treat a lack of visible symptoms as proof that intake is adequate.
- 2
Choose complementary foods
Select whole foods from different groups so their nutrient profiles complement one another. Combine leafy greens, protein sources, and seafood rather than relying on one narrow food category.
Pro tip Favor foods you can afford and eat consistently over an idealized diet you cannot sustain.
- 3
Measure useful markers
Use an appropriate long-term test when a nutrient has a practical biomarker. Patrick uses the red-blood-cell omega-3 index as an example because it reflects a longer period than plasma levels.
Pro tip Match the test to the biological time window it actually measures.
Watch out Do not overinterpret a short-term plasma result as a long-term status marker.
- 4
Close the gaps
Adjust food choices or use a suitable supplement when food alone does not reliably cover a requirement. Reassess after enough time has passed for the marker to change.
Watch out Clinical conditions and high supplement doses require individualized medical advice.
- 5
Optimize avoidance second
Once essential inputs are covered, choose which contaminants, refined foods, or lower-quality sources are worth avoiding. Keep the optimization proportional to its likely benefit and cost.
Pro tip Choose your battles so dietary perfectionism does not displace the basics.
Watch out A long avoidance list can still produce a nutrient-poor diet.
In the wild
A person who has focused mainly on avoiding seed oils audits what the diet actually supplies. They add leafy greens for magnesium and folate, eggs and meat for protein and choline or iron, and salmon plus a tested supplement to improve omega-3 intake. The exclusions remain secondary to covering those repeatable inputs.
→ The diet becomes organized around nutrient coverage rather than fear of individual foods.
Common mistakes
Starting with a blacklist
Avoiding many foods does not establish that the remaining diet supplies essential nutrients.
Optimizing unaffordable details
Obsessing over ideal sourcing can make a workable whole-food diet feel inaccessible.
Is it for you?
Best for
People who are overwhelmed by conflicting lists of foods and ingredients to avoid.
Not ideal for
People who need a clinician-directed therapeutic diet for a diagnosed condition.

“it goes back to this idea this framework that I like to think about nutrition which is what do we need right instead of like…”
“the way I like to think about nutrition is what do I need to get for my diet that is essential for for me to…”
“if you focus on what you actually need guess what you avoid a ton of stuff”
