Nutrients for Your Body Systems: Simple Tips for Better Health

As a functional medicine nutritionist helping women with chronic illness and thyroid issues, I’m excited to share how nutrients support your body’s systems—like your skin, muscles, brain, and heart. Eating a variety of whole foods can keep these systems strong, especially when you have specific health concerns. Let’s break it down in a way that’s easy to understand, with tips to fuel your body for optimal wellness.

Skin and Hair (Integumentary System)

Your skin and hair need nutrients to stay healthy and glowing:

• Fats: Keep skin soft and strong by building its protective barrier. Sebum, an oily substance, moisturizes skin and fights bacteria. Eat avocados, nuts, or olive oil.

• Protein: Collagen, a protein, makes skin firm and elastic. Found in meat, fish, or bone broth.

• Water: Keeps skin hydrated. Dehydration can make skin dry or flaky.

• Micronutrients:

  • Vitamin B12: Balances skin tone and prevents issues like acne or rosacea. Found in eggs or salmon.

  • Vitamin A: Fights aging and acne. Eat carrots, sweet potatoes, or liver.

  • Zinc, Copper, Iron: Help skin heal and stay elastic. Found in shellfish, nuts, and red meat.

Tip: Try a smoothie with spinach, berries, and chia seeds for skin-loving nutrients.

Muscles and Bones (Musculoskeletal System)

Strong muscles and bones need:

• Protein: Builds muscles, tendons, and bones. Collagen (in meat or broth) and other proteins make up 30% of bone mass. Eat chicken, eggs, or lentils.

• Creatine: An amino acid in red meat or poultry that powers muscles for energy.

• Micronutrients:

  • Calcium, Magnesium, Phosphorus: Strengthen bones. Found in dairy, greens, or nuts.

  • Vitamin D: Helps absorb calcium for bone health. Get it from sunlight, fish, or egg yolks.

  • Vitamin K: Locks calcium into bones. Found in leafy greens.

  • Vitamin C: Builds collagen for muscles and bones. Eat oranges or bell peppers.

  • Iron: Delivers oxygen to muscles for energy. Found in beef or beans (pair with vitamin C).

Tip: Enjoy grilled salmon with broccoli for protein, calcium, and vitamin D.

Brain and Nerves (Nervous System)

Your brain and nerves need steady energy and building blocks:

• Carbs: Provide glucose, the brain’s main fuel. Choose complex carbs like oats or sweet potatoes for steady energy, not sugary snacks that harm focus.

• Protein: Makes neurotransmitters for clear thinking and memory. Eat eggs, fish, or tofu.

• Fats: Your brain is 60% fat! Omega-3s (like DHA in salmon) boost memory and healing. Cholesterol (in eggs) supports nerve cells.

• Micronutrients: B vitamins (in whole grains, meat) and magnesium (in nuts) keep nerves firing smoothly.

Tip: Start your day with oatmeal topped with walnuts and berries for brain power.

Hormones (Endocrine System)

Your hormones, including thyroid and reproductive glands, rely on:

• Iodine, Selenium: Make thyroid hormones for energy and metabolism. Found in seaweed, Brazil nuts, or eggs.

• Tyrosine: An amino acid in chicken or soy for thyroid function.

• Zinc: Boosts testosterone and prostate health. Found in oysters or pumpkin seeds.

• Magnesium, Vitamin B6: Ease menstrual cramps and inflammation. Found in spinach or bananas.

• Iron: Replaces what’s lost during periods to prevent heavy bleeding. Eat liver or lentils.

• Cholesterol: Builds hormones like estrogen. Found in eggs or butter.

• Vitamins B2, B9, B12, D: Support thyroid health. Found in dairy, greens, or fish.

Tip: Try a stir-fry with shrimp, quinoa, and greens for thyroid-friendly nutrients.

Heart and Blood Vessels (Cardiovascular System)

Heart health is about reducing inflammation and supporting your heart muscle:

• Fats: Omega-3s (in salmon, chia seeds) lower blood pressure and protect arteries. Saturated fats (in butter) aren’t the villain—recent research shows they don’t cause heart disease. Avoid processed oils like canola.

• Carbs: Soluble fiber (in oats, apples) lowers heart disease risk.

• Micronutrients:

  • Vitamin C, A, E, CoQ10: Antioxidants in fruits, veggies, or organ meats fight inflammation.

  • Potassium, Magnesium, Calcium: Relax blood vessels for healthy blood pressure. Found in bananas, nuts, or dairy.

Tip: Have a bowl of oatmeal with apple slices and flaxseeds for heart health.

Immunity and Lymph (Immune System)

Your immune system needs nutrients to fight infections:

• Carbs: Bright veggies and fruits (like broccoli or berries) provide immune-boosting compounds.

• Protein: Builds antibodies and immune cells. Eat eggs, fish, or beans.

• Fats: Omega-3s (in fatty fish) support immune cells.

• Micronutrients:

  • Vitamin C: Strengthens barriers and white blood cells. Found in citrus or peppers.

  • Vitamin D, A: Regulate immunity. Found in fish, carrots, or sunlight.

  • Zinc: Fights viruses and inflammation. Found in oysters or nuts.

• Water: Keeps lymph fluid moving to clear toxins. Stay hydrated!

Tip: Sip water and snack on oranges with almonds for immune support.

Lungs and Breathing (Respiratory System)

Healthy lungs need:

• Micronutrients:

  • Vitamin C, E, Beta-carotene: Protect lungs from damage. Found in bell peppers, spinach, or carrots.

  • Vitamin D: Strengthens airway barriers. Found in salmon or sunlight.

  • Magnesium: Relaxes lung muscles, easing asthma. Found in nuts or greens.

• Fats: Balance omega-3s (fish) and omega-6s (nuts) to reduce asthma risk.

• Avoid: Inflammatory foods (processed snacks) or allergens (track with a food journal).

Tip: Try steamed carrots with olive oil for lung-friendly antioxidants.

Kidneys and Bladder (Excretory System)

Your kidneys need:

• Water: Flushes waste through urine. Aim for half your body weight in ounces daily (e.g., 75 oz for 150 lbs).

• Micronutrients: Antioxidants (in berries, greens) lower kidney stone risk. Magnesium (in nuts) prevents stones.

• Carbs: Fruits and veggies reduce kidney disease risk.

• Sodium: Keep it low by avoiding processed foods.

Tip: Drink water with lemon and eat a salad with berries for kidney health.

Nutrition Tip

Eat a rainbow of whole foods daily to support all your body systems. Try a plate with grilled chicken, sweet potatoes, and leafy greens for protein, carbs, and micronutrients. Stay hydrated and limit processed foods to reduce inflammation.
