Every time we eat, we are performing a chemical experiment inside our bodies.
Our food contains molecules that react, combine, and release energy through metabolism — a series of chemical reactions that keep us alive.
Let’s analyze one real meal: liverwurst, fried potatoes, and a bread bun (fried in canola oil).
Each part provides different chemical compounds your body uses to build, repair, or energize itself.
🍗 2. Proteins — The Builders
Main Source: Liverwurst Chemical Class: Organic compounds made of amino acids (C, H, O, N)
Proteins are the building blocks of muscles, skin, and enzymes.
In your body, proteins are broken down into amino acids, which are reused to create new tissues.
Equation (simplified):
Protein → Amino Acids → New Proteins + Energy (if needed)
Too little protein: slow healing, fatigue, weak muscles. Too much: strain on kidneys and dehydration.
🧩 Check Your Understanding:
Why do you think your body reuses amino acids instead of creating them from scratch?
🥔 3. Carbohydrates — The Fuel
Main Source: Potatoes and the bread bun Chemical Class: Carbon-based molecules (C₆H₁₂O₆ type structure)
Carbohydrates are made of sugars and starches.
They are broken down into glucose, the body’s main fuel.
Your cells “burn” glucose with oxygen in a reaction called cellular respiration.
Chemical Equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
Too little carbs: tiredness and brain fog. Too many: stored as fat, leading to weight gain.
💭 Science Note:
This process is similar to how fuel burns in a car engine — except your “engine” is a living cell!
🧈 4. Fats — The Long-Term Energy Source
Main Source: Canola oil and liverwurst Chemical Class: Lipids (chains of carbon and hydrogen)
Fats are energy-rich molecules (about 9 kcal per gram) and help absorb vitamins like A, D, E, and K.
Canola oil contains unsaturated fats — a healthier type with flexible chemical bonds.
If oil is heated too high, it oxidizes, producing unwanted compounds called free radicals.
Too little fat: dry skin, low hormones. Too much: clogged arteries, obesity.
⚗️ Chemistry Focus:
Unsaturated fats contain double bonds (C=C) — these are what make the fat liquid at room temperature.
🧬 5. Vitamins and Minerals — The Micronutrient Chemistry
Nutrient
Chemical Role
Too Little
Too Much
Iron (Fe)
Forms part of hemoglobin for oxygen transport
Anemia, fatigue
Liver damage if excessive
Vitamin A (C₂₀H₃₀O)
Needed for vision and cell growth
Night blindness
Headaches, bone pain
Vitamin B12
Helps DNA and nerve function
Numbness, brain fog
Very rare toxicity
Sodium (Na⁺)
Maintains nerve impulses
Muscle cramps
High blood pressure
Potassium (K⁺)
Balances sodium and fluids
Weak muscles
Irregular heartbeat
💡 Key Concept:
Micronutrients don’t provide energy, but they control reactions that do.
They act like “chemical assistants” (called cofactors) that enzymes need to work.
⚖️ 6. Chemical Balance in the Body
Healthy eating is about maintaining chemical equilibrium — just like balancing a chemical equation.
When you eat too much of one nutrient (like sodium or vitamin A), it shifts the balance and causes side effects.
For example:
Too much vitamin A → liver overload, nausea
Too little iron → not enough red blood cell formation
Think of your body as a living chemistry lab constantly trying to stay balanced.

Iodine Deficiency Risk & Best Food Sources
Current Intake & Risk
You eat shrimp once a week, which provides iodine but may not be enough for optimal thyroid health.
The RDA (Recommended Daily Allowance) for iodine is 150 mcg per day (higher for pregnant/breastfeeding individuals).
If shrimp is your only iodine source, you may be falling short, depending on other dietary factors.
Effects of Chronic Iodine Deficiency
❌ Thyroid Dysfunction (Hypothyroidism)
Fatigue, weight gain, sluggish metabolism, cold intolerance
Swollen thyroid (goiter)—the body enlarges the thyroid to absorb more iodine
Brain fog, difficulty concentrating
❌ Hormonal Imbalance
Low iodine can disrupt estrogen/testosterone balance, impacting mood and energy
❌ Skin & Hair Problems
Dry, flaky skin and hair thinning
❌ Impaired Cognitive Function
In severe cases, low iodine in pregnancy can cause developmental issues in infants
How Often Should You Eat Iodine-Rich Foods?
If eating shrimp only once a week, you need other sources daily or at least every 2-3 days.

Include seaweed snacks (1-2 sheets of nori a few times per week).
Eat potatoes with the skin (simple and effective).
Final Verdict: Is Once-a-Week Shrimp Enough?
❌ No—shrimp alone isn’t enough to prevent long-term iodine deficiency.
✅ Solution: Add iodized salt, dairy, eggs, or seaweed to hit the daily requirement.
Would you like simple meal ideas that naturally boost iodine without drastic changes?
Is Eating Potatoes with Skin Every Other Day Enough for Iodine?
Short Answer: ❌ Not quite. While potatoes help, they don’t provide enough iodine alone to meet your body's needs.
Let’s Calculate Your Iodine Intake
Current Iodine Sources in Your Diet
1️⃣ Shrimp (once a week) → ~35 mcg per serving
2️⃣ Potatoes (every other day, with skin) → ~60 mcg per medium potato
➡️ Weekly iodine intake from these sources:
Shrimp (1x per week) → 35 mcg
Potatoes (3-4x per week) → ~180–240 mcg
Total per week:215–275 mcg
➡️ Daily average (divided by 7 days):~31–39 mcg per day
➡️ RDA for iodine:150 mcg per day
⚠️ Deficit: You’re ~110–120 mcg short every day, meaning you’re only getting about 20-25% of what you need.
How to Fix the Gap Without Major Changes
🔹 Best Options to Cover the Missing 110–120 mcg/day:
✅ Use iodized salt in cooking (¼ tsp = ~77 mcg)
✅ Eat 1 egg per day (~24 mcg)
✅ Add dairy (milk/yogurt/cheese) (50–100 mcg per cup)
✅ Eat seaweed once or twice a week (1-2 sheets can provide 40–1000+ mcg)
Easiest Fix: Just add iodized salt while cooking, and you’re almost covered!
Would you like a simple meal plan tweak to ensure you hit 150 mcg daily?
Since you don’t use salt in cooking, you need to rely on natural iodine sources to close the gap.
Revised Iodine Intake Calculation
Shrimp (1x per week) → 35 mcg
Potatoes w/ skin (3-4x per week) → 180–240 mcg total (avg. ~31–39 mcg per day)
Total daily intake:~31–39 mcg per day
RDA for iodine:150 mcg per day
Deficit:~110–120 mcg per day
How to Fix the Deficit Without Salt
Since you don’t use iodized salt, you’ll need to add:
✅ 1 egg per day (~24 mcg)
✅ 1 cup dairy (milk/yogurt/cheese) (~50–100 mcg)
✅ 1-2 sheets of seaweed (nori) per week (~40–1000+ mcg)
✅ Fish (cod/tuna) 1–2x per week (100–150 mcg per serving)
Simplest Fix Without Major Diet Changes
Add 1 egg per day + dairy (milk, cheese, or yogurt) daily → Covers ~75–125 mcg
Eat fish (cod/tuna) once a week → Easily covers the rest

Sophie Carter Clinteastwood years After there meeting
From Her facebook:
"Today marks my 19-year cancerversary—19 years of living with stage IV cancer. It’s a day of both/and for me: a mix of bittersweet gratitude.
Every year on this day, my dad used to call me and say, 'Hey love, how’s my Valentine today?' I miss those words more than I can express. This year, though, I felt his presence in a different way—through spirit.
Yesterday, my mom and I were walking along the beach, sharing our grief over his loss and reflecting on the magnitude of my 19 years. We felt both incredibly blessed that I’m still here and deeply heartbroken that he’s not. As we walked, I silently asked him for a sign: 'Are you still here, Dad?'
This weekend marked the one-year anniversary of his passing, and sometimes it feels like he’s truly gone. But that’s when I saw it: a single red rose lying there on the beach.
It wasn’t the first time he’d sent us flowers. Just two days after he passed, we also found red roses on the shore.
Energy never dies, and neither does love."
This story reminds us that even in the face of loss and pain, love is eternal. Thank you to Kris Carr for sharing this touching moment.
For the highest omega-3 content per 100 grams, chia seeds and the flax, chia, and hemp seeds blend are the most cost-effective options. Hemp seeds also offer a good source of omega-3s at a reasonable price. Coriander, cumin, and caraway seeds provide smaller amounts of omega-3s and are typically used for their culinary flavors and other health benefits.
