Fueling the Mind: How Nutrition Impacts Nerves, Focus, and Performance with RD Alyssum Reno-Smith (Part 1)

What if some of the nerves, brain fog, and missed decisions on the court aren’t about skill - but about fueling?

In part one of our conversation with registered dietitian Alyssum Reno-Smith, we dig into how nutrition directly impacts the nervous system, focus, confidence, and in-game decision making for volleyball athletes. From energy drinks and hydration to carbs as brain fuel, this episode connects the dots between what athletes eat and how they perform - mentally and physically.

This conversation is especially timely as club season kicks off and athletes prepare for long competition days, early mornings, and high-pressure moments.

What you’ll hear in Part 1:

• How under-fueling can increase anxiety, shakiness, and in-game mistakes
• The connection between nutrition, the nervous system, and mental toughness
• Why carbs are the brain’s primary fuel - and how that affects focus and reaction time
• How energy drinks can worsen nerves when they replace real food
• Smart snack strategies for between matches and sets
• Why “not eating at all” before competition can backfire
• How hydration impacts decision making, not just physical performance
• Common fueling misunderstandings parents have - especially for anxious athletes
• The importance of timing food to support both calm and sustained energy

This is just part one - be sure to come back next week as we continue the conversation!
