Damn that croc would of got me good . <| sep |> Dr . Greger ' s advice is wellresearched but not perfect . Like most advice on the Internet , you have to take it with a grain of salt . Like in other areas , there is no onesize fits them all . We have different genes , different environment . What is good for someone might make you sick and vice versa . So even if a study proves that certain foods is good for a population , you have to try it yourself and conclude from that . Or if a food increases risk of cancer in a few people , it might actually be good for you . We also forget that it ' s not just nutrition . There are different sources of food , different ways to cook it , if you exercise , if you smoke , if you have a desk sitting job or if there is manual labor . He can conclude that fish is bad for you . But if fish is the only source of protein where you live , it ' s a very bad idea to cut fish since you would then cut a whole food group . Another example is sugar . If you are a sprinter and train heavily , you could ingest simple sugars and have your body use those sugars without negative effects , even if Dr . Greger tells you something else . So you need to assess if changing your current diet makes sense , if you can integrate it in your lifestyle and keep the habit for life . So I would just use his recommendations as cues and not solid advice . It can show a direction but you need to investigate yourself and make your own conclusions , and possibly look at other cues .
