60 Arbequina Table Olives
Pharmacokinetics Study
Table Olives
At early morning (08:00 h e.g.) and after 10 hours of fasting conditions, the olives of the Arbequina variety will be administered to each subject. The 60 olives will be weighted before the ingestion and the remaining stones will be subsequently weighted to keep a record of the amount of olive pulp that has been consumed. The subjects will have a period of 5 minutes to ingest 60 olives with 240 mL of water. Blood samples will be collected from 1 hour prior to administration until 24 hours after dosing. Urine samples will also be collected and blood pressure will be measured.
120 Arbequina Table Olives
Pharmacokinetics Study

The 120 olives will be weighted before the ingestion and the remaining stones will be subsequently weighted to keep a record of the amount of olive pulp that has been consumed. The subjects will have a period of 10 minutes to ingest 120 olives with 240 mL of water. Blood samples will be collected from 1 hour prior to administration until 24 hours after dosing. Urine samples will also be collected and blood pressure will be measured.
60 Table Olives
Table Olives Nutritional Intervention
Table Olives
All the subjects will perform two experimental sessions of 30 days with 15 days of washout periods within experimental periods. In one experimental session subjects will ingest table olives and in the other session they will act as their own controls following their normal dietary habits. During all the experiment participants will avoid the consumption of products rich in phenolic and triterpenic compounds. Subjects will include the dose of 60 table olives within their normal dietary habits. Consequently, the olives will be consumed two times daily within each main meal; 30 olives before lunch and 30 olives before dinner. Blood samples will be collected at baseline and 15 and 30 days of each experimental session. Tolerability variables and blood pressure will also be measured.
