Abstract: Oilseed by-products ( Cynara cardunculus and Camelina sativa ) (CCCS) are rich in bioactive compounds. This study aimed to evaluate the health effects of consuming yogurt made from goat milk fed with CCCS industrial residues in adults. In this randomized, crossover clinical trial, 20 healthy adults (14F; 37.7 ± 14.2 years) consumed either yogurt made from goat milk fed with CCCS or regular goat yogurt (C) daily for 1 month in each phase. Anthropometric parameters and blood samples were collected at the beginning and end of each phase. CCCS yogurt consumption resulted in a significant fat mass reduction (−1.8% and −1.1 kg) and fat-free mass increase (+1.5% and +0.9 kg). Regarding blood parameters, a non-significant decrease in triglycerides, total cholesterol, and LDL cholesterol was observed, particularly after the CCCS intervention. Moreover, creatinine levels exhibited an opposite trend ( p = 0.023) after CCCS, decreasing in subjects aged ≤30 years (−0.03 mg/dL) and increasing in older subjects (+0.05 mg/dL). Regarding inflammatory parameters, a non-significant trend in increased IL-1ra levels was observed especially after CCCS yogurt consumption compared to the C yogurt (+56.9 vs. +19.1 pg/mL, respectively). The use of unconventional feed derived from oilseed by-products for dairy goat feeding may have potential possible beneficial effects on human health.
