Dietary Fiber 4g 14%
Total Sugars 12g (Includes 8g Added Sugars)
Protein 4g 8%
Vitamin D 0mcg (0%) Calcium 130mg (10%)
Iron 1.8mg (10%) Potassium 94mg (2%)
INGREDIENTS: Rolled oats, whole wheat flour, cane sugar, canola oil, chocolate chips, glycerin, salt, partially hydrogenated soybean oil, natural flavors.
If you eat the entire package (which has 2 servings), how many total calories and how much fat did you consume?
Total Calories: _________ kcal
Total Fat: _________ g
Net carbs are the ones that absorb quickly into energy. Find them by subtracting dietary fiber from total carbohydrates:
Total Carbs (____g) - Fiber (____g) = Net Carbs: ____g
The label lists "Trans Fat 0g". But look at the ingredient list at the bottom of the label. What ingredient shows us that unhealthy trans fats are actually hiding in this food?
Find either Calcium or Iron on the label. Which one did you pick, and why does your body need it?

LAB SHEET 1.3
Meet Marcus:
Marcus is a high-school track runner who trains hard for 2 hours every afternoon. He wants plenty of stamina and fast muscle recovery. He is choosing between two breakfasts:
| Nutritional Element | Option A: Whole Foods | Option B: Processed Foods |
|---|---|---|
| Carbohydrate Type | Complex carbs (rich in fiber) | Simple sugars (no fiber) |
| Energy Release | Slow, steady energy (no crash) | Quick sugar rush, then sudden crash |
| Protein Quality | High-quality complete protein (eggs) | Almost zero protein |
| Fats Quality | Healthy fats (chia seeds, egg yolks) | Unhealthy saturated or trans fats |
1. Why will Option A (Oatmeal & Eggs) keep Marcus energized for his long workout without a sugar "crash" compared to Option B? (Hint: Mention fiber!)
2. Identify three things Marcus needs for athletic performance: one mineral for muscles/bones, one mineral for healthy blood, and water. Name an Option A food that provides them.
3. Why is drinking plain water much better for Marcus's hydration and cell performance than a sugary commercial energy drink?
Unit 1: Human Metabolism - Nutrient Essentials Page 3 of 3
Key Mineral Resolution: Students can choose Calcium (130mg, 10% DV) for strong bone structures and muscle contractions, or Iron (1.8mg, 10% DV) to form hemoglobin and transport oxygen to high-exertion muscles.
1. Avoiding the Sugar Crash (Option A vs. B):
"Option A provides slow-digesting complex carbs with plenty of dietary fiber. Fiber slows down how fast sugars are absorbed, providing steady energy. Option B contains simple sugars with no fiber, which spikes blood sugar and insulin quickly, causing a crash."
2. Three Performance Essentials:
"• Calcium (scrambled eggs/chia) for bone strength and muscle movement; • Iron (scrambled eggs/chia) for carrying oxygen in blood; • Water (fresh water) to transport nutrients and maintain proper hydration."
3. Plain Water vs. Sugary Energy Drinks:
"Plain water hydrates cells directly without extra sugars. Sugary energy drinks can slow digestion, cause stomach cramps, spike blood glucose, and dehydrate cells over time."
Exceeds (4) All calculations are correct; answers demonstrate clear understanding of fiber, healthy fats, and hydration.
Meets (3) Calculations are correct with minor errors; explains core differences between whole and processed foods.
Developing (2) Calculations or terms are incomplete; struggles to explain why fiber or water is beneficial.
Insufficient (1) Leaves label analysis or comparative questions blank; matching section is mostly incorrect.

Macronutrients: Protein Slide 6 of 15
Myth: "Fats are entirely bad." Fact: Fats are vital for high-level survival.
Fats form phospholipids that construct outer protective membranes around all cells.
Fats provide physical layers of shock absorption to protect vital internal organs.
Fats construct myelin sheaths that insulate nerve fibers to speed up brain signals.
Macronutrients: Fats Slide 7 of 15
Not all fats are built the same way physically:
Unsaturated
Liquid at room temp. Beneficial lipids that protect heart pathways (e.g., olive oil, avocados, nuts).
Saturated
Solid at room temp. Usually animal-based (butter, beef fat). Fine in moderation, but limit intake.
Trans Fat
Industrially hardened oils. Extremely unhealthy, raising dangerous cholesterol and damaging blood vessels.
Fat Types Slide 8 of 15
Vitamins regulate chemical reactions. They fall into two categories:
• Vitamin C & B-Complex
• Wash out in urine daily
• Must be eaten every single day
• Vitamins A, D, E, and K
• Store inside body fat tissue
• Do not wash out; overeating them can cause toxicity
Micronutrients: Vitamins Slide 9 of 15
Minerals are inorganic elements required for structural integrity and nerve signaling:
Ca
Calcium: Builds bone mineralization and powers skeletal muscle contraction.
Fe
Iron: Creates hemoglobin to carry oxygen in blood to active muscles.
Na
Sodium & Potassium: Electrolytes that maintain water balance and neural communication lines.
Micronutrients: Minerals Slide 10 of 15
Your body is over 60% water. Why is hydration non-negotiable?
Metabolic Solvent: Water acts as the mandatory liquid playground where metabolic chemical reactions occur.
Temperature Regulation: Perspiration releases body heat, cooling down internal organs.
Dehydration: A mere 2% drop in hydration drops muscle output and severely reduces concentration.
Hydration Essentials Slide 11 of 15
Always investigate food labels in this precise order:
01 Servings
Everything listed is for ONE serving. If the container holds 2, double all values to see the true package total.
02 Net Carbs
Calculate impact carbs:
Total Carbohydrates - Dietary Fiber = Net Carbs. Look for high fiber ratios.
03 Added Sugars
Naturally occurring sugar is fine. Artificially added sugars spike glucose instantly. Keep added sugars low.
Label Reading Strategy Slide 12 of 15
How food manufacturers put unhealthy trans fats in food without listing them:
The Loophole: If a food contains less than 0.5g of trans fat per serving, federal regulations allow the label to print "0g Trans Fat".
The Solution: Read the ingredient list closely. Look for "partially hydrogenated oils".
The Cumulative Load: If you eat multiple servings of a "0g" item containing hydrogenated oil, you are consuming dangerous levels of trans fat.
Label Loopholes Slide 13 of 15
An athlete is training 2 hours. He's choosing between:
Option A: Whole Foods
• Oatmeal, chia seeds, banana, eggs, and water.
• High dietary fiber, high proteins, clean hydration.
Steady 2-hour fuel release.
Option B: Processed Foods
• Frosted toaster pastries, sweet energy drink, snack bar.
• Highly refined simple sugars, no fiber, no protein.
30-minute rush, followed by severe crash.
