Maintaining an adult human body requires a steady stream of structural components and catalyst elements. Tracking individual molecules can feel overwhelming, but looking at exact food yields and understanding how nutrients interact clarifies exactly what is required to maintain homeostatic balance.

1. Macronutrients & Essential Fatty Acids

Macros provide bulk caloric energy and structural rebuilding material. Yields are calculated for a standard 2,000-calorie physiological baseline.

Nutrient Daily Target Exact Food Quantity Bioavailability Hack
Protein ~56g - 70g 200g Chicken Breast OR 350g Tempeh Animal proteins are complete. Pair plant proteins (e.g., rice + beans) to yield all essential amino acids.
Omega-3 (DHA/EPA) 500mg 100g Salmon OR 2g Algal Oil Marine sources are directly usable; plant-based ALA (flax) features a drastically low conversion rate (~5-10%).
Fiber 30g 150g Avocado + 100g Rolled Oats Hydration is required; fiber demands high fluid intake to transit the intestinal system effectively.


2. Fat-Soluble Vitamins

These vitamins build up in fatty tissues and the liver. They absolutely require dietary fats to cross the intestinal threshold.

Target: 900mcg RAE

Vitamin A (Retinol & Beta-Carotene)

Food Equivalents: 100g Cooked Carrots OR 50g Beef Liver.

Bioavailability Note: Raw carrots yield a measly ~3% absorption rate. Cooking them gently and introducing lipid fats (like olive oil) jumps absorption up to ~30-40%.

Target: 20mcg (800 IU)

Vitamin D (Calciferol)

Food Equivalents: 150g Mackerel OR 3 Large Fortified Eggs.

Bioavailability Note: Best absorbed when consumed alongside the heaviest fat-containing meal of your day.

Target: 15mg

Vitamin E (Alpha-tocopherol)

Food Equivalents: 30g Sunflower Seeds OR 50g Almonds.

Bioavailability Note: Highly sensitive to extreme heat. Consume nuts raw or minimally toasted to keep structures fully intact.

Target: 120mcg

Vitamin K (K1 & K2)

Food Equivalents: 50g Kale (K1) OR 15g Natto/Aged Hard Cheese (K2).

Bioavailability Note: K2 sourced from fermented products offers higher tissue accumulation and utilization metrics for bone matrix maintenance than raw green leaf K1.



3. Water-Soluble Vitamins (The B-Complex & C)

Delicate and quickly flushed through the body. Heat and light break down these compounds easily.

Nutrient Quantity Food Equivalent Absorption Detail
B1 (Thiamine) 1.2mg 100g Sunflower Seeds Ethanol blocks transport mechanisms; alcohol consumption severely depletes B1.
B2 (Riboflavin) 1.3mg 250ml Plain Yogurt Highly light-sensitive. Keep dairy products in opaque, UV-shielded containers.
B3 (Niacin) 16mg 150g Turkey Breast Can be synthesized endogenously from the essential amino acid Tryptophan.
B5 (Pantothenic) 5mg 1 Large Avocado Ubiquitous across whole food groups (hence named after pantos, meaning everywhere).
B6 (Pyridoxine) 1.7mg 1 Large Banana Leaches out rapidly into boiling water. Steam, bake, or consume raw where applicable.
B7 (Biotin) 30mcg 2 Cooked Eggs Raw egg whites contain avidin, a protein that tightly binds and completely blocks Biotin. Cook your eggs.
B9 (Folate) 400mcg 150g Boiled Spinach Thermal cooking destroys up to 90% of folate. Mix in raw greens to ensure target capture.
B12 (Cobalamin) 2.4mcg 100g Beef OR 2 Clams Requires gastric Intrinsic Factor to absorb. Absorption rates tend to decline significantly with age.
Vitamin C 90mg 1 Medium Kiwi Fruit Instantly acts as a chemical reducer in the gut, boosting non-heme plant iron absorption by 2-3x.


4. Major Minerals & Elements

Minerals often share metabolic pathways. Taking too much of one mineral can block your body from absorbing another.

Target: 1,000mg

Calcium

Food Equivalents: 100g Parmesan Cheese OR 200g Canned Sardines (including soft bones).

Bioavailability Note: Plant oxalates block calcium. Your gut captures roughly 30% of calcium from dairy, but only 5% from standard raw spinach.

Target: 8mg (M) / 18mg (W)

Iron

Food Equivalents: 150g Sirloin Steak OR 200g Cooked Lentils.

Bioavailability Note: Heme iron from animal flesh enjoys a high 25% absorption matrix. Plant non-heme sits low at 2-10%. Always pair plant-derived iron with citric or ascorbic acid (Vitamin C).

Target: 420mg

Magnesium

Food Equivalents: 50g Pumpkin Seeds + 40g Dark Chocolate (70%+).

Bioavailability Note: Massive isolated inputs of Zinc can directly outcompete and lock out magnesium pathways.

Target: 11mg

Zinc

Food Equivalents: 3 Medium Oysters OR 150g Ground Beef.

Bioavailability Note: Phytic acids found in unrefined cereal hulls bind tightly to zinc. Soaking grains and legumes overnight deactivates phytic constraints.

Target: 3,400mg

Potassium

Food Equivalents: 1 Large Russet Potato (with skin) + 1 Cup Beet Greens.

Bioavailability Note: Highly water-soluble. Boiling vegetables and dumping the water down the drain discards the majority of the mineral content.



5. Trace Elements & Electrolytes

Needed in miniscule amounts, but critical as biochemical keys.

  • Iodine (150mcg): 1/4 tsp Iodized Salt OR 5g Dried Seaweed.
  • Selenium (55mcg): Exactly 1 single Brazil Nut (do not over-consume to prevent selenium toxicity).
  • Copper (900mcg): 10g Beef Liver OR 30g Cashew Nuts.
  • Manganese (2.3mg): 1/2 Cup Mussels OR 1 Cup cooked Brown Rice.


The Core Bioavailability Principles

  • LIPIDS + VEGETABLES: Always accompany fat-soluble profiles (Vitamins A, D, E, K) with a high-quality oil or fat medium.
  • ASCORBIC ACID + BEANS: Introduce citrus drops or fresh pepper slices alongside iron-heavy plant groups.
  • TEMPERED HEATING: Steam gently rather than aggressively boiling to prevent water-soluble vitamins from bleeding out.
  • MANAGE ANTINUTRIENTS: Soak raw seeds, legumes, and grain groupings to mitigate phytic acid blockages.
