Studija naučnika s University of California iz San Diega pokazala je da kod žena sa potvrđenom visokom razinom vitamina D u organizmu, postoji i do 50% manji rizik obolijevanja od raka dojke. Čak je i blago povišena razina vitamina D bila povezana s 10%-tnim smanjenjem rizika za pojavu bolesti, utvrđeno je u istraživanju u kojem je sudjelovalo više od 120000 ispitanica. Vitamin D se u organizmu proizvodi nakon izloženosti sunčevoj svjetlosti, a prisutan je i u ribi, posebno onim vrstama koje obiluju uljem. Viši unos vitamina D se posebno preporučuje starijim osobama. Naučnici upozoravaju kako pretjerana izloženost suncu može imati negativan utjecaj na zdravlje te dodaju kako previsoka razina vitamina D u organizmu može dovesti do opasnog povećanja količine kalcija. Dakle pazite da ne pretjerujete, te održavajte optimalnu razinu vitamina D u organizmu.
