Food & Diet Guides

Welcome to Iowa Sports Prep's food and diet deep dives. These pages explore specific food categories—what they do for your body, how to choose the best options, and how to prepare them for maximum benefit.


Why Learn About Food Categories?

At ISP, we don't believe in one-size-fits-all diets. Different athletes need different approaches. But everyone benefits from understanding:

  • What each food type does for performance, recovery, and long-term health
  • How to choose quality within each category
  • How preparation affects nutrition (cooking can help or hurt)
  • What the science actually says vs. what marketing claims

The Guides

Macronutrient Categories

GuideWhat You'll Learn
Carbohydrates, Starches & LegumesCarb periodization for athletes, resistant starch, beans as the longevity food
Healthy FatsOmega-3 vs. omega-6, brain health, which oils to use (and avoid)
Meat & Animal ProteinQuality matters, protein timing, grass-fed vs. grain-fed, how much is enough

Plant Foods

GuideWhat You'll Learn
VegetablesEat the rainbow, phytonutrients by color, cooking methods that preserve nutrients
FruitsNatural sugars vs. added, best fruits for athletes, timing for recovery
Whole GrainsWhole vs. refined, ancient grains, gluten myths and facts

Specialty Topics

GuideWhat You'll Learn
Fermented FoodsGut microbiome, probiotics, yogurt/kefir/kimchi/sauerkraut
The Danish DietNordic diet principles, sustainability meets health, rye bread culture
Nutrition OverviewWhat's settled in nutrition science vs. what's still debated

Cross-Cutting Themes

1. Quality Over Quantity

A grass-fed steak is nutritionally different from a fast-food burger. An organic apple is different from apple juice. The source and processing matter as much as the category.

2. Whole Foods Win

Across every category, less processed versions outperform refined versions. Whole grains > refined grains. Whole fruits > juice. Nuts > nut oils.

3. Diversity Matters

Eating the same "healthy" foods every day limits your nutrient exposure. Variety—especially in vegetables—provides the full spectrum of micronutrients.

4. Context Is Everything

Carbs aren't "bad"—they're essential for high-intensity training. Red meat isn't "bad"—it's one of the best sources of iron and B12. Dose, frequency, and quality determine the outcome.

5. Cooking Changes Nutrition

Some nutrients are destroyed by heat (vitamin C). Others become more available (lycopene in tomatoes). Smart preparation maximizes what you get from food.


How This Connects to ISP

These food guides inform the Bio Skill Tree in MyPath:

  • Fueling Consistency — Understanding what different foods do
  • Gut Health — Fiber, fermented foods, and the microbiome
  • Recovery Protocol — Post-workout nutrition choices
  • Body Composition — How food quality affects performance weight

When ISP students make food choices, they're not guessing—they understand the science behind each category.
