Forskning om overvekt, fedme og kosthold

Vegetarianere og veganere er i gjennomsnittet slankere enn befolkningen for øvrig
Vegetarianere og veganere er i gjennomsnittet slankere enn befolkningen for øvrig

Flere studier viser at et mer plantebasert kosthold kan beskytte mot overvekt og fedme. Mat fra planteriket har som hovedregel lavere energitetthet og lavere innhold av (spesielt mettet) fett. Fiber finnes kun i matvarer fra planteriket.

«Ett högt intag av animalieproteiner, framför allt från mjölkprodukter, under de första levnadsåren kan bidra till ökad tillväxt och högre BMI i barndomen samt är relaterat till tidigare pubertet och ökad risk för övervikt och fetma senare i livet [26, 27].»

«In conclusion, the intake of protein among children in the Nordic countries is high and may contribute to increased risk of later obesity. The upper level of a healthy intake is yet to be firmly established. In the meantime, we suggest a mean intake of 15 E% as an upper limit of recommended intake at 12 months, as a higher intake may contribute to increased risk for later obesity.»

«A higher animal, especially dairy, protein intake at 12 mo may be associated with an unfavorable body composition at 7 y. The age of 5-6 y might represent another critical period of protein intake for later obesity risk»

«Our results suggest that a decrease in meat consumption may improve weight management.»
«The 5-unit BMI difference between vegans and nonvegetarians indicates a substantial potential of vegetarianism to protect against obesity. Increased conformity to vegetarian diets protected against risk of type 2 diabetes after lifestyle characteristics and BMI were taken into account. Pesco- and semi-vegetarian diets afforded intermediate protection.»

«Fish-eaters, vegetarians and especially vegans had lower BMI than meat-eaters. Differences in macronutrient intakes accounted for about half the difference in mean BMI between vegans and meat-eaters. High protein and low fibre intakes were the factors most strongly associated with increasing BMI.»
