The Healthiest Foods and Supplements for Optimal Health and Pregnancy

Last updated:

Introduction: Building Blocks of Health

Your body relies on essential nutrients, macronutrients, vitamins, minerals, and water as the foundation for optimal function, especially during pregnancy.

These building blocks fuel cellular repair, energy production, immune defense, and hormone synthesis while supporting fetal development and maternal health.

A nutrient-dense diet prevents malnourishment, reduces toxin exposure, and mitigates chronic diseases like heart disease, diabetes, and cancer, as well as pregnancy complications such as gestational diabetes and preeclampsia.

Poor nutrition accelerates aging via oxidative stress and inflammation, harming both mother and baby.

Choosing high-quality foods and supplements ensures peak performance, slows age-related decline, and promotes a healthy pregnancy.

Cooking Methods to Preserve Nutrients

Cooking methods significantly impact nutrient retention, especially for nutrient-dense foods critical in pregnancy.

Raw consumption preserves 95 to 100% of nutrients, ideal for foods like avocados, strawberries, and carrots (if tolerated).

For example, raw carrots retain all beta-carotene, while raw strawberries keep 100% of vitamin C.

However, raw organ meats and seafood carry risks of pathogens like listeria, so cooking is recommended, especially in pregnancy.

Steaming, using minimal water and low heat (100°C), retains 80 to 90% of water-soluble vitamins (e.g., vitamin C, B vitamins) and minerals.

For instance, steaming carrots enhances beta-carotene bioavailability by 20 to 30% compared to raw, while preserving 85% of vitamin C.

Sun-drying or low-temperature oven-baking (below 150°C) retains 75 to 85% of nutrients, ideal for organ meats or fish.

For example, baking salmon at 120°C preserves 90% of omega-3s and vitamin D.

Boiling causes significant nutrient loss, leaching 30 to 50% of water-soluble vitamins (e.g., folate in liver, vitamin C in strawberries) into the cooking water.

Boiling carrots reduces vitamin C by 40%.

Frying in oil or butter (above 180°C) destroys 20 to 40% of heat-sensitive nutrients and introduces oxidized lipids and advanced glycation end-products (AGEs), which increase inflammation and may harm placental health.

For example, frying eggs reduces lutein by 20% and introduces pro-inflammatory compounds.

To maximize nutrient retention, steam vegetables and seafood for 5 to 10 minutes until just tender, bake organ meats at 120 to 150°C for 15 to 20 minutes, and consume fruits like strawberries raw when possible.

Avoid boiling unless using the cooking liquid in soups, and minimize frying to preserve nutrient density and avoid harmful compounds.

Pregnancy Benefit: Nutrient-preserving methods like steaming and low-temperature baking ensure maximum folate, omega-3s, and vitamins for fetal development, reducing deficiency risks and supporting maternal health.
