The purpose of this study is to determine whether a 30 day beef intervention can improve peak cognitive performance in young, normally menstruating adult women. The control group will consume a daily portion of macronutrient equivalent vegetable source of protein.
The purpose of the Nutrition, Vision, and Cognition in Health Sport: Beef (IONSport-Beef) study is to conduct a randomized controlled trial to evaluate beef as a nutritional intervention to optimize visual cognitive training performance in generally healthy, normally menstruating women. Female subjects of reproductive age (18-40) will be randomly placed in one of two dietary treatment groups: one serving of beef per day for 30 days or a non-meat protein replacement control. Cognitive performance will be measured in 15 training sessions over 10 days using the sophisticated NeuroTracker™ CORE (NT) 3-Dimensional (3D) software program. It is hypothesized that women consuming 1 serving of beef per day for 30 days will have the highest plasma levels of the beef rich nutrients and demonstrate the highest visual cognitive performance and improvement as compared to the no beef control.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 30 day Beef consumption | Experimental | One serving of beef is consumed each day for 30 days. |
|
| 30 day Veggie Patty consumption | Placebo Comparator | One serving (1 patty) of a vegetable based protein source is consumed each day for 30 days. The weight of the food, total calories, grams of protein, and total fat are the same as the beef serving. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| 30 day Daily consumption of 1 serving of beef | Dietary Supplement | Beef patty will replace one of the participants protein servings each day for 30 days. Each serving is 114 grams of 90% lean ground sirloin given to participants as an uncooked frozen patty. |
| Measure | Description | Time Frame |
|---|---|---|
| Mean NeuroTracker Speed Threshold over 300 trials | Cognitive Performance on the Neurotracker 3D software program that includes 20 trials in each session. Particpants will track 4 of 8 balls with increasing speed if successful and slower if unsuccessful.The speed threshold is optimized performance for that session. Across the 15 sessions, mean speed threshold is defined as the average speed threshold for the 15 sessions. | 15 sessions (300 trials) over 10 days at the end of the nutritional intervention |
| Maximal NeuroTracker Speed Threshold over 300 trials | Cognitive Performance on the Neurotracker 3D software program that includes 20 trials in each session. Particpants will track 4 of 8 balls with increasing speed if successful and slower if unsuccessful. The speed threshold is optimized performance for that session. Across the 15 sessions, maximal speed threshold is defined as the highest speed threshold. | 15 sessions (300 trials) over 10 days at the end of the nutritional intervention |
| Change in NeuroTracker Speed Threshold over 300 trials | Cognitive Performance on the Neurotracker 3D software program that includes 20 trials in each session. Particpants will track 4 of 8 balls with increasing speed if successful and slower if unsuccessful. The speed threshold is optimized performance for that session. Across the 15 sessions, change in speed threshold is defined as the difference between the mean of the first three sessions and the mean of the last three sessions. | 15 sessions (300 trials) over 10 days at the end of the nutritional intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Blood Markers of anemia | blood levels of B12, iron, CBCs, ferritin, hepcidin | Day 1 and Day 30 of the intervention |

Study participants will be randomized to either one serving of beef or a macronutrient equivalent "veggie patty" per day for 30 days.

note on masking: The title of the study presented to participants is "IONsport: Women and Protein" and the funding source is withheld to mask from participants our underlying hypothesis. It is open label in the sense that they know what they are eating.

| 30 day Daily consumption of 1 serving of the vegatable protein source | Dietary Supplement | Veggie patty will replace one of the participants protein servings each day for 30 days. No beef will be consumed during this period. The veggie patty is commercially available Morningstar veggie burger and is given to participants in commercial packaging as a frozen precooked patty. |
