Life & Plate
Your body's nutritional playbook changes with every chapter of life — and with every dietary choice you make. Here's the science on what actually matters.
Life Stages with Special Considerations
Different stages demand different fuel. These are the nutrients you literally cannot afford to miss.
Infants & Young Children
6–23 months
The most nutrient-critical window in the entire human lifespan.
🔬 Key Nutrients
✅ What to Do
- ›Prioritize minimally processed, nutrient-dense animal-source foods: unprocessed red meat, organ meats, fish, shellfish, eggs, and unsweetened dairy
- ›Include dark green leafy vegetables, legumes, nuts, and seeds
- ›Limit sugar-sweetened beverages and unfortified refined grains — they displace nutrient-dense foods
Adolescents
10–19 years
The second-fastest growth period. Nutrient demand spikes hard.
🔬 Key Nutrients
✅ What to Do
- ›Load up on iron-rich foods: lean red meat, organ meats, bivalves (oysters, mussels)
- ›Hit calcium + Vitamin D targets through dairy, dark leafy greens, and fortified foods
- ›Minimize empty-calorie snacks and sugary drinks that crowd out real nutrition
Pregnant Women
All trimesters
You're building a human. Nutrient needs are non-negotiable.
🔬 Key Nutrients
✅ What to Do
- ›Focus on nutrient-dense animal sources: eggs (choline), bivalves (B12), low-mercury seafood (DHA)
- ›Folic acid supplementation is recommended before and during early pregnancy
- ›Ensure adequate iodine through iodized salt, dairy, or seafood
Lactating Women
Postpartum
Nutrient and energy needs exceed even pregnancy levels.
🔬 Key Nutrients
✅ What to Do
- ›Prioritize high-quality protein: dairy, eggs, meats, DHA-rich seafood
- ›Include folate-rich legumes and greens daily
- ›B12, iodine, Vitamin A, and DHA in breast milk are directly determined by what you eat
Women of Reproductive Age
Non-pregnant, non-lactating
Iron is the #1 priority. Deficiency is common and often silent.
🔬 Key Nutrients
✅ What to Do
- ›Pair plant-based (non-heme) iron with Vitamin C-rich foods to boost absorption
- ›Consider iron-rich foods at every meal: red meat, lentils, spinach, fortified cereals
- ›Begin folic acid supplementation before conception for neural tube defect prevention
Older Adults
65+ years
Energy needs drop. Nutrient needs don't. Precision matters.
🔬 Key Nutrients
✅ What to Do
- ›B12 supplementation or fortified foods may be necessary since food-source absorption declines with age
- ›Higher protein intake is non-optional — aim for 1.2 g/kg to preserve muscle mass
- ›Ensure 800 IU Vitamin D + 1,200 mg Calcium daily to reduce fracture risk
Special Considerations for Plant-Based Diets
Going vegan or vegetarian? Respect. But your body doesn't care about ideology — it needs specific nutrients. Here's how to not fall short.
Nutrients That Need Your Attention
Vitamin B12
Critical RiskVirtually 100% of vegans have intakes below the RDA without fortified foods or supplements.
Deficiency risks include megaloblastic anemia and permanent neurological damage.
Strategy: Mandatory: fortified foods (nutritional yeast, plant milks) or B12 supplements.
🍽️ In Practice
Iron
High RiskPlant-based (non-heme) iron is 2–3× less bioavailable than animal-source (heme) iron.
Absorption further inhibited by phytates (grains/legumes) and tannins (coffee/tea).
Strategy: Pair iron-rich plants with Vitamin C. Avoid coffee/tea with meals. Cook in cast iron.
🍽️ In Practice
Zinc
Moderate–High RiskFound in legumes and grains but 'locked' by phytic acid, reducing bioavailability.
Inadequate zinc impairs immune function, wound healing, and growth.
Strategy: Soak, sprout, or ferment grains and legumes to break down phytic acid and unlock zinc.
🍽️ In Practice
Omega-3s (EPA/DHA)
High RiskConversion of ALA (flax, walnuts) to active EPA/DHA is highly inefficient — less than 10%.
Low DHA may impair brain function, mood regulation, and cardiovascular health.
Strategy: Algae-based EPA/DHA supplements are the most reliable vegan source.
🍽️ In Practice
Choline
Moderate–High RiskPrimarily found in animal products (eggs, liver). Only 10% of Americans meet the Adequate Intake.
Vegans are at particularly high risk of inadequacy. Critical during pregnancy.
Strategy: Focus on soy, quinoa, broccoli, and cruciferous vegetables. Consider supplementation.
🍽️ In Practice
Protein on Plants: The Complete Picture
The Problem
Plant proteins can be lower in certain essential amino acids — lysine in grains, methionine in legumes.
The Fix
Combine complementary proteins: beans + rice, hummus + pita, lentils + quinoa.
Complete Sources
Soy (tofu, tempeh, edamame) and mycoprotein deliver all essential amino acids in one hit.
Plant-Based at Every Age: Know the Risks
👶Infants of Vegan Mothers
- ⚠Exclusively breastfed infants require Vitamin B12 supplements (0.4 mcg/day) from birth
- ⚠Iron supplements (1 mg/kg/day) recommended from 4 months of age
🧒Vegan Children
- ⚠High-fiber vegan diets can trigger 'early satiety' — children feel full before meeting caloric needs
- ⚠Include energy-dense foods: nut butters, avocados, oils, and dried fruits
🧓Older Vegan Adults
- ⚠Age-related B12 malabsorption + absence of B12 in vegan foods = 'double-risk' scenario
- ⚠Mandatory B12 supplementation or fortification is non-negotiable
