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.

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.

Minerals Made Simple: The Body’s Spark Plugs
As a functional medicine nutritionist helping women with chronic illness and thyroid issues, I’m excited to share why minerals are essential for your health. These tiny nutrients act like spark plugs, powering everything from strong bones to steady energy. Let’s break down the 16 essential minerals in an easy-to-understand way and explore how to get them through food.
What Are Minerals?
Unlike vitamins, minerals are inorganic elements from the earth, found in soil and water. Plants absorb them, animals eat the plants, and we get minerals from both. Unlike fragile vitamins, minerals are tough—they don’t break down. Your body needs them in small amounts to keep nerves firing, muscles moving, and bones strong. A varied, nutrient-dense diet is the best way to get them, especially since soil quality can affect mineral levels in food.
Minerals are split into two groups:
Major minerals: Needed in larger amounts (over 100 mg/day), like calcium or sodium.
Trace minerals: Needed in tiny amounts (100 mg or less), like iron or zinc.
Major Minerals: The Big Players
Calcium: The most abundant mineral, 99% is in your bones and teeth for strength. The rest helps muscles (including your heart) contract, nerves communicate, blood clot, and blood pressure stay healthy. Found in dairy, sardines (with bones), tofu, broccoli, and leafy greens. Plant sources like spinach are less absorbable due to compounds like oxalates. Vitamin D and good digestion boost absorption. Low calcium can weaken bones, especially for women with thyroid issues.
Sodium: Found in salt, sodium balances fluids outside cells, supports nerve signals, and regulates blood pressure with potassium. Too much from processed foods can raise blood pressure, but in a whole-food diet, it’s usually fine. Found in sea salt, shrimp, and soy sauce. Low sodium (rare) can cause headaches or nausea.
Potassium: Balances fluids inside cells and works with sodium for nerve signals and muscle movement. Found in fruits (bananas, dried apricots), vegetables, beans, and nuts. Low levels (rare) can raise blood pressure or cause muscle cramps.
Chloride: Pairs with sodium to balance fluids and is part of stomach acid for digestion. Found in salt, seaweed, and shrimp. Deficiency is rare.
Phosphorus: Second most abundant, mostly in bones and teeth. It’s also in DNA, cell membranes, and energy processes. Found in dairy, meat, fish, and nuts. Plant sources (grains, seeds) are less absorbable. Deficiency is rare.
Magnesium: Powers hundreds of reactions, including energy, blood sugar control, and muscle relaxation. Found in leafy greens, nuts, seeds, and whole grains. Low levels can cause cramps or poor sleep, common in chronic illness.
Sulfur: Part of amino acids, insulin, and B vitamins. Found in eggs, meat, broccoli, and onions. Deficiency is rare due to its wide availability.
Trace Minerals: Small but Mighty
Iron: Key for hemoglobin (carries oxygen in blood) and myoglobin (stores oxygen in muscles). Supports DNA, hormones, and immunity. Found as heme iron (highly absorbable) in meat, oysters, and liver, or non-heme iron(less absorbable) in beans and spinach. Vitamin C boosts non-heme iron absorption; calcium or phytates (in grains) can block it. Iron deficiency (common) causes fatigue and anemia, especially in women.
Zinc: Needed for cell growth, immunity, and wound healing. Found in oysters, red meat, and shellfish; plant sources like oats are less absorbable. Low zinc (rare) can weaken immunity or slow healing, a concern for vegetarians or those with digestive issues.
Copper: Supports energy, iron use, collagen, and immunity. Found in liver, oysters, nuts, and chocolate. Deficiency is rare but can affect blood cells.
Manganese: Helps metabolize nutrients and form bones. Found in grains, nuts, and tea. Deficiency is rare.
Iodine: Crucial for thyroid hormones that control metabolism, growth, and temperature. Found in seaweed, shrimp, eggs, and iodized salt. Low iodine can cause fatigue, weight gain, or goiter (enlarged thyroid), critical for thyroid health.
Selenium: An antioxidant protecting cells and supporting thyroid function. Found in Brazil nuts, meat, eggs, and grains. Deficiency is rare in the U.S.
Fluoride: Strengthens teeth to prevent cavities. Found in tea, coffee, and fluoridated water. Excess in kids can harm teeth, so monitor intake.
Chromium: Boosts insulin to regulate blood sugar. Found in liver, eggs, and broccoli. Deficiency (rare) may mimic diabetes symptoms.
Molybdenum: Helps detox toxins and break down sulfites. Found in legumes, nuts, and liver. Deficiency is very rare.
Why Minerals Matter
Minerals keep your body running smoothly:
Build strong bones and teeth (calcium, phosphorus).
Power nerves and muscles (sodium, potassium, magnesium).
Carry oxygen and fight infections (iron, zinc).
Support thyroid and metabolism (iodine, selenium).
Balance fluids and digestion (sodium, chloride).
For women with chronic illness or thyroid issues, minerals like iodine and selenium are vital for hormone balance and energy, while magnesium and zinc reduce inflammation and stress.
Nutrition Tip
Eat a variety of whole foods to get your minerals. Try salmon with leafy greens for calcium and magnesium, or oysters for zinc and iron. Pair plant-based iron sources (like lentils) with vitamin C-rich foods (like bell peppers) to boost absorption. Use unrefined sea salt sparingly for iodine and sodium. If digestion is impaired, a nutritionist can help assess mineral needs.
A Holistic Approach
Minerals work with vitamins and macronutrients to fuel your health. For women managing chronic conditions, a mineral-rich diet can boost energy, strengthen immunity, and support thyroid function. Stay tuned for tips on personalizing your nutrition!

Micronutrients Made Simple: Tiny Nutrients, Big Impact
As a functional medicine nutritionist supporting women with chronic illness and thyroid issues, I’m excited to share the power of micronutrients—vitamins and minerals that your body needs in small amounts but with a huge impact on health. Let’s break down the science in an easy-to-understand way and explore how these tiny nutrients keep you thriving.
What Are Micronutrients?
Unlike macronutrients (carbs, proteins, fats) needed in large amounts, micronutrients are required in tiny doses—think milligrams or micrograms. They include vitamins (organic compounds from food) and minerals (inorganic compounds from soil or water). Despite their small size, they’re essential for energy, immunity, strong bones, and more, especially for women managing chronic conditions.
Vitamins: Your Body’s Helpers
Vitamins are like little assistants for your body’s processes. There are 13 vitamins, split into two groups:
Water-soluble vitamins: Dissolve in water, so excess is peed out. You need them regularly since they aren’t stored much. These include B vitamins and vitamin C.
Fat-soluble vitamins: Need dietary fat to be absorbed and can be stored in your body’s fat and liver. These are vitamins A, D, E, and K.
Vitamins are fragile—heat, light, or cooking can damage them—so fresh, minimally processed foods are best.
Water-Soluble Vitamins
B1 (Thiamine): Helps turn food into energy, especially for your brain, heart, and liver. Found in pork, fish, whole grains, and beans. Low levels (rare) can cause fatigue or muscle weakness.
B2 (Riboflavin): Boosts energy and helps break down nutrients. Found in milk, eggs, leafy greens, and beef. Deficiency (rare) may cause tiredness or cracked lips.
B3 (Niacin): Supports energy, cell communication, and antioxidants. Found in poultry, fish, rice, and peanuts. Severe lack (very rare) causes pellagra (skin issues, diarrhea).
B5 (Pantothenic Acid): Helps make energy and fats. Found in eggs, broccoli, nuts, and fish. Deficiency is uncommon due to its wide availability.
B6 (Pyridoxine): Key for protein use and over 100 body reactions. Found in bananas, chickpeas, and poultry. Low levels can occur with inflammation or heavy alcohol use.
B7 (Biotin): Supports metabolism and cell signaling. Found in egg yolks, salmon, and nuts. Deficiency is rare but can affect hair or skin.
B9 (Folate): Vital for making DNA and red blood cells, especially during pregnancy to prevent birth defects. Found in leafy greens, legumes, and citrus. Low folate can cause anemia.
B12 (Cobalamin): Needed for nerves, blood cells, and DNA. Found only in animal foods like fish, eggs, and dairy. Vegans or those with poor digestion may lack it, causing fatigue or anemia.
Vitamin C: A powerful antioxidant that boosts immunity, builds collagen, and helps absorb iron. Found in oranges, bell peppers, and kiwi. Lack of it (scurvy, rare today) causes weak tissues and slow healing.
Fat-Soluble Vitamins
These need fat to be absorbed and are stored in your body, so deficiencies are rare but can happen if fat digestion is impaired (common in some chronic conditions).
Vitamin A: Supports vision, skin, and immunity. Found as retinol in liver and eggs, or as beta-carotene (a precursor) in carrots and squash. Beta-carotene also fights cell damage.
Vitamin D: Acts like a hormone, aiding bone health by helping absorb calcium and reducing inflammation. Found in fatty fish, egg yolks, or made by your skin in sunlight. Low levels can weaken bones.
Vitamin E: An antioxidant protecting cells, especially fats, from damage. Found in almonds, sunflower seeds, and spinach. Deficiency is rare but can affect nerves.
Vitamin K: Helps blood clot and strengthens bones. Found as K1 in leafy greens and K2 in fermented foods. Low levels (rare) can cause bleeding issues.
Why Micronutrients Matter
Micronutrients are like the spark plugs in your body’s engine. They:
Turn food into energy (B vitamins).
Protect cells from damage (vitamins C, E).
Build strong bones and tissues (vitamins D, K, folate).
Support immunity (vitamins A, C, D).
Keep nerves and muscles working (B vitamins, minerals).
For women with thyroid issues or chronic illness, micronutrients are crucial to reduce inflammation, boost energy, and support hormone balance. A diet low in micronutrients can lead to fatigue, weak immunity, or worse—especially if digestion is compromised.
Nutrition Tip
Eat a rainbow of whole foods daily to get your micronutrients. Try a spinach salad with salmon and avocado for vitamins A, D, and E, or snack on oranges and bell peppers for vitamin C. Cooking gently (steaming, not overboiling) preserves vitamins. If you avoid animal foods or have digestive issues, talk to a nutritionist about your B12 or vitamin D needs.
A Holistic Approach
Micronutrients work with macronutrients to keep your body in balance. For women with chronic conditions, a nutrient-dense diet can transform energy and health. Stay tuned for more on tailoring nutrition to your unique needs!

Fats Made Simple: Why They’re Essential for Your Health
As a functional medicine nutritionist helping women with chronic illness and thyroid issues, I’m here to break down the science of fats in a way that’s easy to understand. Fats aren’t just about flavor—they’re vital for energy, hormone balance, and overall wellness. Let’s explore what fats are, how they work in your body, and how to choose the best ones for your health.
What Are Fats?
Fats, also called lipids, are waxy or oily substances in food and your body. The most common type is triglycerides, which are made of a glycerol (a small molecule) and three fatty acids (long chains). Think of triglycerides like a bundle of energy stored in foods like butter or olive oil and in your body.
Fats can be solid (like butter) or liquid (like olive oil) at room temperature. This depends on the type of fatty acids they contain.
Understanding Fatty Acids: The Building Blocks of Fats
Fatty acids are chains of carbon atoms with a special group at one end (called a carboxyl group) and a different group at the other (called the omega end). They differ in two ways:
Length:
Short-chain (2-4 carbons): Found in some dairy.
Medium-chain (6-12 carbons): Like in coconut oil.
Long-chain (14-26 carbons): Common in most fats, like olive oil or fish.
Saturation: This is about how many hydrogen atoms the chain holds.
Saturated fats: Full of hydrogen, no gaps (double bonds). They’re straight, pack tightly, and are solid at room temperature (e.g., butter).
Monounsaturated fats: One gap (double bond), creating a bend. They’re liquid or soft (e.g., olive oil).
Polyunsaturated fats: Two or more gaps, more bends, very liquid (e.g., fish oil).
The shape matters! Saturated fats are sturdy and stable, great for cooking. Monounsaturated and polyunsaturated fats are less stable, better for low-heat or no-cook uses.
Types of Fats in Food
No food is purely one type of fat—it’s always a mix. For example:
Lard: Often called a saturated fat, but it’s actually 47% monounsaturated and 41% saturated.
Butter: Mostly saturated, but softens at room temperature because of some unsaturated fats.
Good sources include:
Saturated fats: Butter, ghee, coconut oil, or fats from grass-fed animals (great for high-heat cooking).
Monounsaturated fats: Olive oil, avocados, almonds (use for low-heat cooking or dressings).
Polyunsaturated fats: Fatty fish (salmon, sardines), walnuts, chia seeds (don’t cook; store in the fridge).
Avoid industrial oils like canola, soybean, or margarine. These are heavily processed, often oxidized, and linked to health issues like heart disease or diabetes.
Why Your Body Needs Fats
Fats do so much more than provide energy. Here’s why they’re essential, especially for women with chronic illness or thyroid issues:
Energy: Fats are like slow-burning logs in a fire, providing steady energy for long activities or between meals, unlike quick-burning carbs.
Vitamin Absorption: Fats help your body absorb vitamins A, D, E, and K, found in foods like butter or nuts.
Cell Health: Fats, especially phospholipids, form the flexible walls of your cells. Too many polyunsaturated fats make cells too loose; too many saturated fats make them too stiff. A balance keeps cells healthy.
Hormones: Fats are needed to make hormones like estrogen and progesterone, crucial for thyroid health and overall balance.
Satiety: Fats make you feel full longer by slowing digestion and signaling your brain to stop eating.
Organ Protection: Fats cushion and protect your organs.
Flavor: Fats make food taste amazing, from a drizzle of olive oil to a creamy avocado.
Omega-3s and Omega-6s: The Essential Fats
Two polyunsaturated fats are essential because your body can’t make them:
Omega-3s (e.g., ALA, EPA, DHA): Found in salmon, chia seeds, or grass-fed beef. They reduce inflammation and support brain and heart health.
Omega-6s (e.g., LA): Found in nuts, seeds, or organic peanut butter. They’re needed but can promote inflammation if overconsumed.
The ideal omega-6 to omega-3 ratio is 1:1 to 4:1, but many Western diets hit 15:1 or higher due to processed oils. This imbalance fuels inflammation, linked to chronic diseases. To balance:
Eat more omega-3s: Try salmon, walnuts, or flaxseeds.
Cut omega-6s from processed oils: Swap canola oil for olive oil and check labels on snacks.
Omega-3s (like EPA/DHA from fish) are more effective than plant-based ALA, which converts poorly to EPA/DHA. For thyroid health, omega-3s reduce inflammation and support hormone function.
Fats and Inflammation
Omega-3s and omega-6s turn into prostaglandins, hormone-like molecules that control inflammation:
Omega-6s can make pro-inflammatory prostaglandins (PGE2), which help fight injury but cause issues if overproduced.
Omega-3s make anti-inflammatory prostaglandins (PGE3), calming inflammation.
A balanced diet with more omega-3s shifts your body toward less inflammation, vital for managing chronic illness.
Cholesterol: Not the Villain
Cholesterol, a waxy lipid, has a bad rap but is crucial:
Your body makes 70-80% of it (mostly in the liver).
It’s used to make vitamin D, hormones (like estrogen), and bile (to digest fats).
It strengthens cell membranes and supports brain health (25% of your cholesterol is in your brain!).
Eating cholesterol-rich foods (like eggs) doesn’t always raise blood cholesterol—your body adjusts production. For thyroid health, cholesterol supports hormone production, boosting energy and balance.
Nutrition Tip
Incorporate a variety of fats daily. Drizzle olive oil on salads, cook eggs in ghee, or snack on walnuts. Avoid processed oils and prioritize whole foods like avocados or salmon. For thyroid support, focus on omega-3s to reduce inflammation.
A Balanced Approach
Fats are a powerhouse nutrient, working with proteins and carbs to fuel your body. For women with chronic illness or thyroid issues, a diet rich in high-quality fats can improve energy, hormone balance, and overall health. Next, we’ll explore micronutrients and personalized nutrition!

The Basics of Nutrition: Unlocking the Power of Carbohydrates
As a functional medicine-based nutritionist working with women managing chronic illness and thyroid conditions, I’m excited to dive into the Basics of Nutrition, focusing today on the vital role of carbohydrates. Nutrition and the body’s anatomy and physiology are deeply intertwined, and understanding how nutrients like carbohydrates fuel and support your body is key to optimal health.
Why Nutrition Matters
Nutrition is the science of how food interacts with our bodies, providing essential nutrients to sustain life. These nutrients supply energy, build cells and tissues, and regulate critical processes like hormone and enzyme production. A well-balanced diet supports every system—digestive, respiratory, urinary, and reproductive—while deficiencies can impair function and exacerbate chronic conditions. For women with thyroid issues, proper nutrition is especially crucial for energy, hormone balance, and overall wellness.
Nutrients: The Building Blocks of Health
Nutrients fall into two categories:
Macronutrients: Needed in large amounts, including carbohydrates, proteins, fats, and water. Carbohydrates, proteins, and fats provide energy, while water supports countless functions.
Micronutrients: Vitamins and minerals, required in smaller amounts, act as coenzymes and cofactors for biological processes.
Today, we’ll focus on carbohydrates, exploring their types, roles, and how they support your body.
Carbohydrates: Your Body’s Preferred Fuel
Carbohydrates, composed of carbon, hydrogen, and oxygen, are found in starchy vegetables, fruits, tubers, legumes, grains, and sweeteners. They’re the body’s primary energy source, especially for the brain and muscles, and play a critical role in digestion and overall health.
Types of Carbohydrates
Simple Carbohydrates (Sugars):
Monosaccharides: Single sugars like glucose (blood sugar, vital for energy), fructose (found in fruits, the sweetest sugar), and galactose (converted to glucose by the liver).
Disaccharides: Paired sugars, including maltose (two glucose molecules, from starches), sucrose (glucose + fructose, in granulated sugar), and lactose (glucose + galactose, in dairy).
These are digested quickly, providing immediate energy.
Complex Carbohydrates (Polysaccharides):
Starches: Chains of glucose molecules in foods like potatoes, rice, and grains. They digest more slowly, offering sustained energy.
Resistant Starches: Found in oats, beans, and cooled rice or potatoes, these resist digestion until the colon, where they feed the microbiome.
Fibers: Found in plant foods, fibers are indigestible but essential. Soluble fibers (e.g., in apples, oats) slow digestion, stabilize blood sugar, and feed gut bacteria. Insoluble fibers (e.g., in whole grains, leafy greens) speed digestion and promote regular bowel movements.
Functions of Carbohydrates
Energy: Carbohydrates provide quick energy, with glucose fueling the brain and muscles. Excess glucose is stored as glycogen in the liver and muscles or converted to fat for long-term storage.
Protein-Sparing: Adequate carbohydrate intake prevents the body from breaking down muscle protein for energy.
Digestive Health: Fibers promote regular bowel movements, stabilize blood sugar, and nourish the microbiome, supporting immunity and gut health.
Micronutrient Delivery: Whole-food carbohydrates like fruits and vegetables provide essential vitamins and minerals.
Carbohydrates and Blood Sugar
The Glycemic Index (GI) measures how quickly a carbohydrate raises blood sugar, with pure glucose at 100. However, GI doesn’t account for serving size. Glycemic Load (GL) is more practical, reflecting the impact of a standard serving. For example, watermelon has a high GI (72) but a low GL (4) due to its low carbohydrate content per serving.
Choosing Healthy Carbohydrates
Opt for whole-food carbohydrates like starchy vegetables, fruits, legumes, and whole grains. Refined grains (e.g., white flour) lack fiber and nutrients, spiking blood sugar like sugar. Resistant starches (e.g., cooled rice, green bananas) and fibers (e.g., oats, leafy greens) support digestion and microbiome health. For women with thyroid conditions, stable blood sugar from low-GL foods can reduce inflammation and fatigue.
Low-Carb Diets: A Balanced Perspective
Low-carb diets may aid short-term weight loss or specific conditions, but long-term restriction can lead to constipation, fatigue, nutrient deficiencies, and risks like osteoporosis or heart disease. As a nutritionist, I believe a bio-individualamount of high-quality carbohydrates is essential for a balanced diet, especially for women with chronic illnesses.
Nutrition Tip
Incorporate a variety of whole-food carbohydrates daily. Try a breakfast of overnight oats with berries for soluble fiber, or a lunch of cooled quinoa salad with roasted vegetables for resistant starch. Stay hydrated to support digestion and pair carbs with protein and fats to stabilize blood sugar.
Looking Ahead
Carbohydrates are just one piece of the nutrition puzzle. In future posts, we’ll explore proteins, fats, and micronutrients, plus strategies to tailor nutrition to your unique needs. For women with chronic illness or thyroid challenges, a nutrient-dense diet can transform energy and vitality.
