NCT ID: NCT04279418 Completed - Alzheimer Disease Clinical Trials

Non-pharmacological Intervention for Preclinical Alzheimer's Disease

Start date: April 1, 2019
Phase: N/A
Study type: Interventional

Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective drugs targeting this disease. Functional food is considered as a potentially non-pharmacologic treatment. In this project, the investigators aim to investigate the effectiveness of a mixed functional food with main compositions of ginsenoside, green tea polyphenols and marine collagen peptide on cognition for individuals with subjective cognitive decline (SCD). Taking the randomized, double-blind, placebo-controlled method, participants in the functional food group will take mixed functional foods for three months and those in the placebo group will take placebo. After that, the investigators will investigate the changes of cognitive function. Furthermore, based on the neuroimaging technique, the regulatory mechanism of functional food in intervening SCD will be revealed from the perspective of altered brain functional activity. In conclusion, these results are beneficial for understanding the therapeutic effect of mixed functional foods as a non-drug treatment for early AD and further elucidating the potential brain mechanism, which are of great values in solving scientific and clinical practice issues.

NCT ID: NCT03886597 Completed - Healthy Clinical Trials

Nutritional Intervention With Table Olives in Healthy Volunteers

BIOLIVA
Start date: March 25, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Olives and olive oil are typical components of the Mediterranean diet being part of its cultural and gastronomic heritage. Since ancient times, olives have been used either for both, oil extraction or whole fruit consumption as table olives. Olive oil stands out from both the nutritional and the health point of view. However, the effect of table olives consumption remains almost unknown. The beneficial properties of olive oil have been initially ascribed to the high concentration of oleic acid. Nowadays, these positive effects have been attributed also to minor compounds such as polyphenols or pentacyclic triterpenes. Table olives contain a higher amount of both polyphenols and pentacyclic triterpenes than their oil, with the same healthy fatty acid profile. Therefore, the present intervention aims at investigating the pharmacokinetic of polyphenols and pentacyclic triterpenes after a single olive intake as well as the assessment of the effect of the consumption of olives during 30 days on the overall health status playing particular attention to the anti-inflammatory, antioxidant and cardiovascular biomarkers.
