Caryocar brasiliense Cambess (pequi) is the fruit of the pequizeiro tree found in the Brazilian Cerrado (savanna). Supercritical fluids have been used to effectively extract bioactive chemicals. In light of the paucity of research on the supercritical extraction of pequi, in this study, experimental tests were conducted on the extraction of pequi almond oil using supercritical CO_2; the optimal extraction conditions were determined, and the fatty acids and active compounds in the oil were characterized. The experiments were conducted using the Box–Behnken experimental design of a three-variable system: pressure (15, 20, and 25 MPa), temperature (303.15, 318.15, and 333.15 K), and flow rate (2, 3, and 5 g.min⁻¹). The optimal extraction conditions were 318.15 K, 25 MPa, and 5.0 g.min⁻¹, which yielded 27.6 wt% of oil. The experimental kinetic curves were described using a second-order quadratic model (based on the Sovová model), which demonstrated a satisfactory correspondence with the kinetic curves. Significant amounts of squalene, stigmasterol, oleic fatty acids, and palmitic fatty acids were detected in pequi almond oil.

Coconut oil is obtained from the pulp of fresh ripe coconut and can be extracted in different ways; either by artisanal, solvent or mechanical extraction. Unlike other vegetable oils, this one has a high content of medium chain fatty acids, which represent around 60% of its composition. This high content of medium chain fatty acids results in several benefits for the human organism. The present study aimed to evaluate the impacts caused by the daily consumption of coconut oil on the reduction of the abdominal circumference of men and women and on weight loss, its antibacterial activity against Staphylococcus aureus and, finally, its influence on the prevention and development of Alzheimer's. Most of the fatty acids present in coconut oil are rapidly absorbed in the intestine, generating energy quickly, even without suffering the action of pancreatic lipase enzymes. From the bibliographic review carried out, the effectiveness of coconut oil in reducing the abdominal circumference of men and women and weight loss was considered, in addition to its antibacterial activity against Staphylococcus aureus and its influence of coconut oil on prevention and development Alzheimer's disease. However, it was considered viable to consume up to 12 grams of coconut oil daily, and can be used as a substitute for other oils of vegetable origin.

A vitamina D é um suplemento vitamínico mineral, sua função está relacionada à saúde dos ossos, responsável também por outras atividades. Ela regula o crescimento, sistema imunológico, cardiovascular, músculos, metabolismo e insulina, mantendo as concentrações adequadas de cálcio e fósforo no organismo. Objetivou-se fazer um levantamento bibliográfico sobre a necessidade do consumo da vitamina D para manutenção da saúde, apresentando a importância da suplementação a pessoas acima de 65 anos, mulheres gestantes e as doenças desencadeadas pela carência dela. A vitamina D é lipossolúvel e adquirida por meio de alimentos e pelos raios solares. Neste trabalho foram avaliadas principais doenças causadas pela falta da vitamina D, observando que o consumo exagerado pode causar sérios problemas como a obesidade, em contrapartida, a falta causa desnutrição. Através de estudos analisados conclui-se que a biodisponibilidade da vitamina D está associada a regulação e manutenção para uma vida saudável.
