What is Omega-6 fatty acid?
[[Image:LAnumbering.png|375px|thumb|The [[chemical structure]] of [[linoleic acid]], a common omega-6 fatty acid found in many [[Nut (fruit)|nuts]], [[seeds]], and [[vegetable oil]]s.]] '''Omega-6 fatty acids''' are a family of [[Polyunsaturated fat|polyunsaturated fatty acids]]. Some medical research notes that high levels of omega-6 fatty acids from seed oils may increase the chance for a number of [[disease]]s.<ref>{{cite journal |title=Healthy Intakes of n-3 and n-6 fatty acids|issue=6 |pages=1483S–1493S |journal=American Journal of Clinical Nutrition|date=June 2006 |volume=83 |doi=10.1093/ajcn/83.6.1483S |url=https://academic.oup.com/ajcn/article/83/6/1483S/4633242|accessdate=May 14, 2021|last1=Hibbeln |first1=Joseph R. |last2=Nieminen |first2=Levi RG |last3=Blasbalg |first3=Tanya L. |last4=Riggs |first4=Jessica A. |last5=Lands |first5=William EM |pmid=16841858 }}</ref> However, having non-rancid [[Nut (fruit)|nuts]], which are high in omega-6, is associated with lower risk for some diseases, including [[cardiovascular disease]]s, [[stroke]], [[myocardial infarction|heart attacks]] and certain [[cancer]]s.<ref>{{cite journal|title=Nut Consumption and Risk of Cardiovascular Disease|year=2016|journal=BMC Medicine|pmc=5137221|last1=Aune|first1=D.|last2=Keum|first2=N.|last3=Giovannucci|first3=E.|last4=Fadnes|first4=L.
