Effects of Camelina Sativa Oil in Free-living Older Adults

Evaluation of the Anti-inflammatory Effects of a Snack Enriched With Camelina Sativa Oil in Free-living Older Adults: a Randomized, Double-blind, Placebo-controlled Study

The present study aims at evaluating the anti-inflammatory effects of a novel food in older adult volunteers. Briefly, this randomized, double-blind and placebo-controlled study is performed on 91 apparently healthy older adults (age≥65 years) before and after 12 weeks' consumption of a snack enriched with camelina Sativa oil. Subjects were randomized into two groups (active group vs placebo group).

Ninety-one volunteers (26M/65F) are enrolled according to the following inclusion criteria i) free-living older adults ≥ 65 years; ii) apparently healthy subjects; iii) subjects who do not take vitamin supplements/integration and/or omega 3 polyunsaturated fatty acids; iv) subjects without food allergies. All volunteers are informed about the purpose of the study and the potential risk and provide their informed consent. Subjects are randomized into two groups: active group (13M/36F) vs placebo group (13M/29F). The main objective of this project is to test the efficacy of the 12-weeks consumption of a novel food (snack enriched with camelina Sativa oil) on the inflammatory status in older adults. The primary and secondary endpoints are: i) Investigation of changes in serum CRP levels and serum levels of pro- and anti-inflammatory cytokines, in the active group (volunteers consumed enriched snack with camelina Sativa oil) and placebo group, after 12 weeks of snacking (T1), compared to baseline (T0) (primary endpoint). ii) Evaluation of changes in serum lipid panel parameters after the consumption of the novel food in both the active and placebo groups (secondary endpoint). iii) Evaluation of changes in glucidic status after the consumption of the novel food in both the active and placebo groups (secondary endpoint). iv) Evaluation of changes in the levels of omega 3 polyunsaturated fatty acids in both the active and placebo groups (secondary endpoint). v) Evaluation of the nutritional status at T0 and at T1 in both the active and placebo groups (secondary endpoint).

Investigation of changes in serum CRP levels (pg/mL) and serum levels of pro- and anti- inflammatory cytokines (TNF-α, pg/mL; TGF-beta1, pg/mL and TGF-beta2, pg/mL; IL-18 pg/mL).

Evaluation of changes in serum lipid panel parameters (total cholesterol, mg/dL; triglycerides, mg/dL; HDL cholesterol, mg/dL; LDL cholesterol, mg/dL).

Evaluation of nutritional status by assessing the serum levels of vitamin B9 (ng/mL) and vitamin D (ng/mL).

Evaluation at baseline of Body Mass Index (Kg/m2) to investigate the prevalence of overweight or obesity.

Evaluation at baseline of Waist to height ratio (WHtR) as a proxy of fat distribution and metabolic diseases risk.

Evaluation at baseline of reactance (Ohm) and resistance (Ohm) by using vectorial bioimpedance analysis.
