Vitamin D is a mineral vitamin supplement, whose function is related to bone health, also responsible for other activities, regulates growth, immune system, cardiovascular, muscles, metabolism and insulin, maintaining the proper concentrations of calcium and phosphorus in the body. When combined with other micronutrients, vitamin D becomes fat-soluble, acquired through food and sunlight. The main diseases caused by lack of vitamin D were evaluated, noting that excessive consumption can cause serious problems, such as obesity, already lacking malnutrition. From the studies analyzed, it can be concluded that vitamin D bioavailability is associated with regulation and maintenance for a healthy life. This study exposes the need for maintenance of vitamins for maintenance, presenting the importance of supplementation for people over 65 years and pregnant women.

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 CO2; 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.

Food deficiency and physical inactivity are factors that influence the quality and life expectancy of human beings, impairing their immunity to possible health problems, giving rise to contamination by SARS-CoV-2 viruses that mainly affect people with malabsorption of nutrients. The Covid-19 disease virus in contact with the mouth, eyes and nose where it binds like cells of the mucosa that creates new cells that multiply contaminating cells that cause symptoms that cause mild symptoms such as sore throat, cough and fever, reaching symptoms more serious that can be fatal due to the difficulty in breathing, affecting the health of the elderly and vulnerable people with respiratory problems. Why care methods should be avoided, starting with food as a form of care and avoiding vitamin D supplementation.
