An interventional study of dark chocolate and non dark chocolate in Healthy, sponsored by Loma Linda University. Completed at 1 site in United States. Open to participants aged 21 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2018-06-25.
Sponsored by Loma Linda University · Not applicable, Interventional, and Other
The purpose of this graduate student study is to determine if ingestion of dark chocolate (70% cacao) will change brain frequencies between visualization at a state of rest and a state of exercise performance via electroencephalography (EEG) in vigorously active individuals.
The procedures include: On day one, participants will fill out a dark chocolate Likert scale, physical activity assessment, and demographic questionnaire. Day two and three, on consecutive days will include, three EEG measurements will be recorded: 1) at baseline, 2) during visualization of rest for one minute, and 3) during visualization of usual vigorous exercise for one minute. The second day all three measurements will be recorded without dark chocolate (70% cacao). The third day all three measurements will be recorded again. Measurements 2 and 3 will be recorded savoring dark chocolate and after fully ingesting the dark chocolate respectively.
Loma Linda University is the lead sponsor of 297 studies on the registry; 48 are open to participants now.
Of its 28 completed or terminated interventional studies of FDA-regulated products, 23 (82%) have results posted.

Exclusion Criteria:
Three EEG measurements will be recorded: 1) at baseline, 2) during visualization of rest for one minute, and 3) during visualization of usual vigorous exercise for one minute. Measurements 2 and 3 will be recorded savoring dark chocolate and after fully ingesting the dark chocolate respectively.
Dietary Supplement: dark chocolate
three EEG measurements will be recorded: 1) at baseline, 2) during visualization of rest for one minute, and 3) during visualization of usual vigorous exercise for one minute.
Other: non dark chocolate
Participants will be provided Parliament dark chocolate (70% cocoa) from Redlands, CA. The Parliament chocolate is made with cacao and cane sugar. Each participant will be given half a piece (1.4 g) of dark chocolate to consume for this experiment over three minutes.
No dark chocolate will be given to this group during the procedures.
EEG Wave Band Activity without dark chocolate ingestion
The EEG, electroencephalogram, is a test that detects abnormalities in the brain waves or the electrical activity of the brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto the scalp. The electrodes detect tiny electrical charges that result from the activity in the brain cells. EEG wave band activity will be recorded from 9 cerebral cortical scalp locations: F3, Fz, F4, C3, Cz, C4, P3, Pz, and P4 using the EEG B-Alert 10X System, Carlsbad CA. Each of the brain frequencies will be measured in 5 second increments. Data collection will last no longer than 2 hours for each session.
Time frame: change from baseline to during visualization of rest for one minute
