Abstract [en]

A series of food surveys suggest that the dietary intake among the Swedish population has changed substantially in recent years. Fat intake has increased whereas carbohydrate intake has decreased. The reason for this change is not clear but it has been suggested to be an effect of the public breakthrough of high-fat diets such as LCHF (Low Carbohydrate High Fat).

In this study we attempt to shed light on the associations between food intake, attitudes to different diets and the information sources with regard to food, nutrition and health.

The study is based on data collected from 311 students at the Linnaeus University, from 2015 through 2017. Food intake was identified through three-day food records using Dietist Net software. Opinions about diets, and the degree to which different sources of information were used to obtain diet-related information, were evaluated through questionnaires. Where applicable, Pearson’s correlation tests were performed in SPSS.

In general, the students reported a low intake of iron, carbohydrates and alcohol as well as a high intake of dietary fiber, folate and selenium, relative to Nordic Nutrition Recommendations and national food surveys. Out of ten selected diets, the students ranked Nordic Nutrition Recommendations and the Mediterranean diet as the healthiest diets and the LCHF and Atkins diets as the least healthy diets. The correlation tests identified a number of associations between dietary intake and opinions about diets. Similar diets were associated to each other, such as Paleo, LCHF and Atkins diet on one hand, and Nordic Nutrition Recommendations, Vegan, Low-fat and Weight Watchers diet on the other hand. However, the Mediterranean diet, Gluten-free and 5:2 diets were associated with both low-carbohydrate diets and high-carbohydrate diets. As previous research has suggested, an association between media use and attitudes to diets which is reflected in dietary intake, can be observed. The main conclusion is that there are associations between and within reported dietary intake, information sources regarding cooking, diets and health and reported opinions regarding different diets. However, causality cannot be elucidated by this analysis.

Abstract [sv]

Ett flertal kostvaneundersökningar tyder på att kostintaget bland den svenska befolkningen har förändrats väsentligt de senaste åren. Fettintaget har ökat medan kolhydratintaget har minskat. Anledningen till denna förändring är oklar men det har föreslagits att media kan vara en orsak, där framför allt låg-kolhydrat-hög-fettsdieter har fått mycket utrymme.

I den här studien försöker vi lyfta fram samband mellan kostintag, attityder till olika dieter och informationskällorna när det gäller matlagning, kost och hälsa.

Studien är baserad på data som samlats in från 311 studenter vid Linnéuniversitetet, från 2015 till 2017. Kostintaget identifierades genom tre dagars kostregistrering med hjälp av Dietist Net. Åsikter om dieter och hur ofta informationskällor används utvärderades genom en enkät. Statistisk analys gjordes med Pearsons korrelationstest i SPSS.

Studenterna rapporterade ett lågt intag av järn, kolhydrater och alkohol samt ett högt intag av kostfiber, folat och selen i förhållande till nordiska näringsrekommendationer och nationella kostvaneundersökningar. Av tio utvalda dieter rankade studenterna Nordiska Näringsrekommendationer (NNR) och medelhavskost som de hälsosammaste dieterna och LCHF- och Atkinsdieten som de minst hälsosamma dieterna. Korrelationstesterna identifierade ett antal samband mellan kostintag och åsikter om dieter. Liknande dieter var förknippade med varandra, såsom Paleo, LCHF och Atkins samt NNR, vegan, fettsnål kost och Viktväktarkost. Tre dieter; Medelhavskost, glutenfritt och 5:2 dieten visade samband med både lågkolhydratsdieter och högkolhydratsdieter. Som tidigare forskning har föreslagit visas samband mellan medieanvändning och attityder till dieter vilket även återspeglas i kostintaget. Den huvudsakliga slutsatsen är att det finns samband mellan och inom rapporterat kostintag, informationskällor om matlagning, kost och hälsa samt rapporterade åsikter om olika dieter. Kausalitet kan dock inte belysas genom denna analys.
