Intag av stekt mat och övervikt

[King Grub]

BACKGROUND AND AIMS:

The consumption of fried foods is believed to be linked with obesity and higher weight gain, however, the evidence from long-term randomized trials or prospective epidemiological studies is scarce. Therefore, the aim of our study was to prospectively evaluate the association between the consumption of fried foods and weight change and the incidence of overweight/obesity in a Mediterranean cohort.

METHODS AND RESULTS:

Prospective cohort study of 9850 men and women with a mean age of 38.1 years (SD 11.4) were followed-up for a median of 6.1 years to assess average yearly change in body weight, and incidence of overweight/obesity. The consumption of fried foods was associated with higher weight gain, but the differences were of small magnitude and statistically non-significant. The incidence of overweight/obesity during follow-up was also assessed in the subset of 6821 participants with initial body mass index <25 kg/m(2) (initially free of overweight/obesity), after adjusting for potential confounders, the odds ratio for developing overweight/obesity among participants who consumed fried foods >4 times/week was 1.37 (95% confidence interval: 1.08 to 1.73) in comparison with those who consumed fried foods <2 times/week (p for trend = 0.02).

CONCLUSION:

In this Mediterranean prospective cohort, a more frequent consumption of fried foods at baseline was associated with a higher risk of subsequently developing overweight/obesity during follow-up.

Är "fried food" samma sak som "stekt mat"? Är inte "fried" "friterad" eller blandar jag ihop det? Det kanske inte gör någon skillnad?

[Trashcan]

Jag tänker också friterad mat. Fast det heter ju "frying pan" så jag vet inte. Hur som helst innehåller ju både friterad och stekt mat i regel mer kalorier, så det var väl kanske ingen shocker.

Friterat blir "Deep Fried" på engelska.

Abstract

Objective The traditional Mediterranean food pattern is more easily preserved when meals are eaten at home; however, as a result of recent socio-economic changes, away-from-home meal consumption has increased rapidly in Mediterranean countries. Little research has been conducted so far to investigate the long-term health effects of these changes in the Mediterranean area.

Design In a prospective Spanish dynamic cohort of 9182 university graduates (the SUN Study; Seguimiento Universidad de Navarra, University of Navarra Follow-up) with a mean age of 37 years, followed up for an average of 4·4 years, we assessed the association between the frequency of eating out of home and weight gain or incident overweight/obesity. Dietary habits were assessed with an FFQ previously validated in Spain.

Results During follow-up, eating-out consumers (two times or more per week) had higher average adjusted weight gain (+129 g/year, P < 0·001) and higher adjusted risk of gaining 2 kg or more per year (OR = 1·36; 95 % CI 1·13, 1·63) than non-eating-out consumers. Among participants with baseline BMI < 25 kg/m2, we observed 855 new cases of overweight/obesity. Eating away-from-home meals was significantly associated with a higher risk of becoming overweight/obese (hazard ratio = 1·33; 95 % CI 1·13, 1·57).

Conclusions A higher frequency of meals eaten out of home may play a role in the current obesity epidemic observed in some Mediterranean countries.

Abstract
BACKGROUND:

High consumption of sugar-sweetened drinks has been associated with weight gain and obesity in the United States. This trend may also be affecting populations with different eating patterns who increasingly are adopting typical US dietary patterns.
OBJECTIVE:

We assessed whether the consumption of sweetened drinks and other food items increased the likelihood of weight gain in a Mediterranean population.
DESIGN:

This was a prospective cohort analysis of 7194 men and women with a mean age of 41 y who were followed-up for a median of 28.5 mo with mailed questionnaires. Dietary exposure was assessed with a previously validated semiquantitative food-frequency questionnaire.
RESULTS:

During follow-up, we observed that 49.5% of the participants increased their weight (x weight gain: 0.64 kg; 95% CI: 0.55, 0.73 kg). In the participants who had gained > or =3 kg in the 5 y before baseline, the adjusted odds ratio of subsequent weight gain for the fifth quintile compared with the first quintile of sugar-sweetened soft drink consumption was 1.6 (95% CI: 1.2, 2.1; P for trend = 0.02). This association was absent in the participants who had not gained weight in the 5-y period before baseline. The consumption of hamburgers, pizza, and sausages (as a proxy for fast-food consumption) was also independently associated with weight gain (adjusted odds ratio for the fifth compared with the first quintile = 1.2; 95% CI: 1.0, 1.4; P for trend = 0.05). We also found a significant, but weaker, association between weight gain and both red meat and sweetened fruit juice consumption.
CONCLUSION:

In a Mediterranean cohort, particularly in the participants who had already gained weight, an increased consumption of sugar-sweetened soft drinks and of hamburgers, pizza, and sausages was associated with a higher risk of additional subsequent weight gain.

Sammantaget verkar det som att de som äter mest skit blir fetast. :)

Det är nog framförallt på grund av mängden.

Fast vid uppföljningen såg man ju skillnader i subgruppen.

Och det ansåg man bero på stekt mat? Inget annat? Hur drar man ens bort andra faktorer?

Man kan exempelvis kontrollera för totalt kaloriintag och fettsammansättning. Ingen säger ju att det beror på det, det är ju en observationsstudie. Men det var samband och de kvarstod även efter att man kontrollerat för vissa confounders. Exakt vilka vet jag inte.

Men naturligtvis kan man aldrig kontrollera för allt i en livsstil. Så är det ju jämt.

[Ronn]

Tycker det låter som väldigt modiga slutsatser att dra med alla faktorer inblandade.
