Vita Hjertego og de nye reklamene deres

[Anisa]

...som Jåbekk skriver helt avslutningsvis:

"Alle premissene for Mills' markedsføring er feil. Mettet fett er ikke skadelig,
men flerumettet plantefett i høye doser kan sannsynligvis være det.

At Mills bruker denne feilinformasjonen for å reklamere for sine produkter og dermed samtidig sprer ukunnskap,
som med stor sannsynlighet vil kunne være til skade for folks helse..."

At flerumættet plantefedt også er goitrogen (thyreoideahormon UNDERtrykkende) bekymrer øjensynligt hverken margarineproducenter eller Mattilsynet, eller Fødevarestyrrelsen i Danmark. I 1970-erne har man endda overvejet at visse fedtsyrer i flerumættet plantefedt kunne anvendes direkte i behandling af hyperthyreose:

Abstract
ATP citrate lyase, acetyl-CoA synthetase, malic enzyme and hexose monophosphate dehydrogenase activities and rates of View the MathML source synthesis of long chain fatty acids from labeled acetate and citrate were measured in cell-free fractions of liver from rats fed various diets, with and without D- or L- thyroxine. Diets containign sucrose (vs. isocaloric glucose) or lard (vs. isocaloric corn oil) stimulated hepatic lipogenesis both in control and in thyroxine-treated rats. The lipogenic response to thyroxine was greatly modified by diet, except for an invariable rise in malic enzyme activity. With diets providing less than 6% of calories as linoleic acid, thyroxine increased fatty acid synthesis, depleted liver glycogen and retarded growth; when linoleic acid was increased to 16% of calories, thyroxine had no effect on fatty acid synthesis or growth and liver glycogen depletion was significantly attenuated. This response to dietary linoleic acid suggests that these phenomena may be largely secondary to the increased requirement for essential fatty acid in thyrotoxicosis. Further study should reveal the extent to which observed effects of excess thyroid hormone are amenable to control by dietary polyunsaturated fat.
