Simply Salt and Soul

As we gear up for baseball season, my kitchen has become a bit of a fueling station for my two boys. In my studies in holistic nutrition, we spend a lot of time looking at the biochemical demands of the body, and there is no clearer example of high demand than a growing athlete on the diamond.

When we talk about protein, it’s easy to get lost in “grams per day” or social media trends. But from a holistic perspective, we look at how protein functions as a structural necessity and a metabolic messenger.

1. The Science: Growth vs. Maintenance

In nutrition science, we look at a concept called positive nitrogen balance. This is a key marker of growth and development for young athletes.

Building vs. Maintaining: While we adults mainly use protein to repair our existing cells (maintenance); our teenagers are using it to build brand-new ones. Since they are in a constant growth spurt (with bones lengthening and muscle mass increasing) their baseline protein needs are actually higher than ours. They aren’t just maintaining what they have; they are literally building a bigger version of themselves every single day.

The Repair Cycle: Think of every game or heavy practice as creating tiny “micro-tears” in their muscle fibres—almost like small frays in a rope. To fix them, the body uses amino acids (those building blocks of protein) to patch and strengthen those fibres. This repair process is exactly what helps their muscles adapt, grow, and become more resilient for the next time they take the field.

2. The Holistic Pillar: Absorption is Everything

One of the most important things I’m learning is that the body relies not just on what we eat, but how well we break down and utilize those nutrients. You can consume a high-protein meal, but if digestion feels off, it may influence how comfortably that meal is processed.

Chewing (The first step): Digestion actually begins in the mouth. Athletes are notorious for “inhaling” post-game meals, but thorough chewing mechanically breaks down food, providing more surface area for stomach acid to do its job.

The Role of HCL: To turn complex proteins into the amino acids the body can actually use, the stomach needs a highly acidic environment and specific digestive enzymes. When we are stressed or eating on the run, our body stays in “fight or flight” mode, which can slow down this acid production and make digestion uncomfortable. Creating a relaxed environment at the dinner table helps the body stay in “rest and digest” mode so it can actually utilize the nutrients you’re eating.

Bioavailability: We focus on whole-food sources like eggs, lean meats, beans, and seeds. These foods don’t just provide protein—they also deliver key vitamins and minerals, such as B6, B12, zinc, and magnesium, which help the body break down and use protein effectively. By choosing whole foods, your athlete gets a complete nutrient package, rather than just a single macro, supporting both growth and recovery.

3. The Math: How Much Do They Actually Need?

To find your athlete’s optimal protein target, calculate grams per kilogram of body weight. The RDA (0.8g/kg) is a minimum to prevent deficiency, but growing and active teen athletes may benefit from a higher intake—typically around 1.2–2.0 g/kg, depending on their sport, training intensity, and stage of growth.

To calculate this for your athlete:

Divide their weight in lbs by 2.2 to get their weight in kg
Multiply that kg weight by your target (e.g., 1.5g)

Example: A 150 lb teen athlete (68 kg) would aim for roughly 102g of protein per day during periods of higher training demand.

Protein Pacing: Once you have that target number, how they eat it matters. Spreading this protein out across 4-5 meals and snacks throughout the day is far more effective for muscle repair than eating a massive 60g steak at dinner.

Hydration and Protein: A quick reminder for sports parents—if you are increasing your athlete’s protein intake, their water intake must increase as well. This helps the kidneys process the extra nitrogen waste and keeps their system running efficiently. When there’s an increase in protein, the body produces more urea (a nitrogen byproduct) that the kidneys must filter out. Without extra water, the kidneys have to pull fluid from elsewhere, leading to systemic dehydration and extra organ stress.

Note: These calculations are intended for healthy, active individuals. If you or your athlete have specific health concerns—such as kidney or metabolic conditions—it is always best to consult with your healthcare practitioner to determine the range that is right for your unique needs.

4. Bio-Individuality: Finding the Balance

The right amount of protein is different for everyone. In our house, my boys’ needs change day-to-day based on:

Training Load: A heavy pitching day needs way more recovery support than a simple rest day.

Growth Spurts: During a “stretch,” the body’s demand for calories and building materials shoots up significantly.

The Energy Bridge: We make sure protein doesn’t crowd out the complex carbs (like sweet potatoes, oats, or fruit) that provide the actual energy needed to play the game.

The Recovery Ratio: After a game, I aim for a 3:1 or 4:1 ratio of carbs to protein. Pairing a protein source with three times as many carbs—like a turkey sandwich and a piece of fruit—is the best way to refill their energy tank while letting those proteins get straight to work repairing muscle.

The Bottom Line

Protein is more than a macro—it is the structural foundation for the young athletes in our lives. By prioritizing bioavailable sources and supporting the digestive process, we provide the building blocks they need to thrive on the field and maintain long-term metabolic health.

I’d love to hear from other sports parents: How do you navigate the “post-game hunger” while keeping meals balanced and nutrient-dense? Let’s share some strategies in the comments!

The Salt (The Science): Protein requires a specific environment to be broken down effectively. In the stomach, hydrochloric acid (HCL) denatures the protein and activates the enzymes that turn it into usable amino acids. For a busy athlete, eating too quickly or under stress can hinder this process. A simple ritual, like a squeeze of lemon in water before a meal, helps signal the digestive system to prepare for food and encourages a more mindful pace for better absorption.

The Soul (The Wellness): There is a direct connection between how we fuel and how we show up for our lives. For a teenager, protein is the physical foundation for their growth. Choosing whole-food sources is a practical way to respect that process. It changes a post-game meal from a chore into a moment of recovery. When we provide the right building blocks, we are supporting the body’s natural ability to build, adapt, and stay resilient.
