Det farlige fettet!

En statistisk forelesning av den svenske legen Andreas Eenfeldt, som skriver bloggen Kostdoktorn.



I 1984 startet en skremselkampanje i USA om at mettet fett øker kolesterolet, og at forhøyet kolesterol leder til hjertekarsykdommer. Kampanjen spredde seg til resten av den vestlige verden, med det resultatet at folk flest ble redd for fett. Eenfeldt viser overvektsstatistikken for USA fra 1984 og frem til idag. Man kan tydelig se at fedmen i befolkningen økte betraktelig. I dag er tallene for fedme mer enn tredoblet, og forekomst av hjertekarsykdommer har hatt en skremmende økning.

Hva skjedde på disse årene?
Jo, fettinntaket gikk ned, karbohydratinntaket (sukker og stivelse) økte, og folk ble fetere og sykere. Er det en "missing link" her et sted, eller kan forklaringen være så enkel? Jeg tror det siste!
En interessant forelesning som kan være verdt en time av din tid.

  1. Den gode doktoren har ikke gjort historieleksene sine, da denne kampanjen har pågått siden 1920-åra. Og den fikk ny giv og større mediadekning da Ancel Keys kom med sin fetthypotese i midten av 50-åra, som imidlertid var helt feil, da han baserte seg på studier på transfett og helse, og ikke mettet fett og helse. Rundt 1985 fikk denne hypotesen en ny propagandarunde, som svar på stadig nyere forskning som viste det motsatte av Key's hypotese, utover å vise at de data han hadde basert hypotesen på var feil.

    På følgende nettsider finner man info som motbeviser alle påstander om mettet fett eller kolesterol som sykdomsårsak -

    1. Hei igjen! Du skal bare fylle kommentarfeltene mine:) Som du ser, så er jeg nystartet i bloggverdenen, og har ikke fått all verdens med kommentarer til nå. Jeg studerer ernæring, og synes det du kommer med er veldig interessant og lærerikt.

      Visjonen for bloggen er ikke helt ferdig-pønsket. Men til nå har jeg landet på at jeg ønsker å skrive korte, informative innlegg til "hvermansen", som ønsker og kanskje behøver å lære mer om riktig ernæring. Det vil nok derfor være mye som er veldig forenklet, kanskje så forenklet at det nesten blir feil, og som enkelte ganger kanskje også kommer til å bli helt feil:) Vi får se.. Så det vil være mye rom for pirk:)

      Forøvrig så har Kostdoktorn skrevet om Ancel Keys og 7-landsstudien i bloggen sin, og jeg mener det står i boken hans også. Mulig fedmestatistikken viser et bedre poeng i fra 1985 og frem til idag, og at det var derfor tidligere historikk ble litt knapp i forelesningen. http://www.kostdoktorn.se/fettskrackens-sista-dodsryckning-innan-renassansen/

    Superiority of Butter (oleo=margarin)
    Children of adolescent age, fed oleo and butter, side by side, over a few years demonstrated that oleo feeding caused castration of both sexes in a considerable degree, as indicated by excessive height of both boys and girls, greater weight increase in girls than boys, and neutral physiques in both - girls had broader shoulders and narrower hips than normal, boys vise versa. Sex development demands vitamin E, and butter is our main source in the American diet. And we do NOT mean synthetic substitutes for the natural vitamin E complex. Take vitamin E out of its environment by “purifying” it and it loses up to a 99% of its potency, say authorities –

    Saturated Fat Miracle
    I saw your website and I want to briefly tell you about my wife. She has had autistic symptoms all her life, and for the last two years, Addison symptoms so serious she was a semi-invalid and very depressed. She is now cured (since last August). She is happy, works hard, no symptoms, no medication; all her lifelong autism symptoms are gone as well! It was truly a miracle. By accident and out of desperation she tried a diet extremely high in saturated fat. That was all. In three days she was a new person! I think someone should get the word out about this –

    1. Pass the Saturated Fat
      The Aetna InteliHealth website (featuring Harvard Medical School's Consumer Health Information and ads for Revival soy products) continues to lambast "cholesterol-rich foods" such as fatty meats, butter and full-fat cheeses. "All vegetable oils are a healthier alternative to butter and lard," they say, "because they can be rich in polyunsaturated or monounsaturated fats—both of which can modestly lower cholesterol." We'd like to remind the folks at Harvard and Aetna about a study published in the British Medical Journal almost 40 years ago. Patients who had already had one heart attack were assigned to one of three groups and given polyunsaturated corn oil, monounsaturated olive oil and saturated animal fats respectively. The endpoints were further heart attack or death. Blood cholesterol levels were lowered by an average of 30 percent in the corn oil group while there was no change in the other two groups. However, at the end of the two-year trial only 52 percent of the corn oil group were still alive and free of a fresh heart attack. Those on the monounsaturated olive oil fared little better: 57 percent survived and had no further heart attack. But those eating saturated animal fats fared the best with 75 percent surviving and without further attack (BMJ 1965;1:1531-33). The recent crescendo of anti-saturated-fat/pro-statin polemic does not come from convincing new evidence, we think, but from a sense of desperation. The public just isn't buying the propaganda anymore. Even a small percentage of American consumers returning to real foods like butter and cheese is enough to send the whole agricultural/pharmaceutical/food processing complex, built on the vegetable oil/lowfat dairy paradigm, into a tailspin - http://www.westonaprice.org/caustic_comments/fall2003.html
