Low carbohydrate high fat-diet in real life assessed by diet history interviews.

BACKGROUND: Low carbohydrate high fat (LCHF) diet has been a popular low carbohydrate diet in Sweden for 15 years. Many people choose LCHF to lose weight or control diabetes, but there are concerns about the effect on long-term cardiovascular risks. There is little data on how a LCHF diet is composed in real-life. The aim of this study was to evaluate the dietary intake in a population with self-reported adherence to a LCHF diet. METHODS: A cross-sectional study of 100 volunteers that considered themselves eating LCHF was conducted. Diet history interviews (DHIs) and physical activity monitoring for validation of the DHIs were performed. RESULTS: The validation shows acceptable agreement of measured energy expenditure and reported energy intake. Median carbohydrate intake was 8.7 E% and 63% reported carbohydrate intake at potentially ketogenic levels. Median protein intake was 16.9 E%. The main source of energy was dietary fats (72.0 E%). Intake of saturated fat was 32 E% and cholesterol was 700 mg per day, both of which exceeded the recommended upper limits according to nutritional guidelines. Intake of dietary fiber was very low in our population. The use of dietary supplements was high, and it was more common to exceed the recommended upper limits of micronutrients than to have an intake below the lower limits. CONCLUSIONS: Our study indicates that in a well-motivated population, a diet with very low carbohydrate intake can be sustained over time and without apparent risk of deficiencies. High intake of saturated fats and cholesterol as well as low intake of dietary fiber remains a concern.

[Sweden introduces a new specific ICD-10 code for the disease familial hypercholesterolemia]. / E78.0A ­ en unik, ny ICD-10-kod för familjär hyperkolesterolemi - Rätt använd kan koden bli ett effektivt verktyg.

At the turn of the year 2018/19, a new ICD-10 code (E78.0A) will be introduced in Sweden for the hereditary blood lipid disorder familial hypercholesterolemia (FH). Patients with FH have a significantly increased risk of developing atherosclerotic disease, such as myocardial infarction before the age of 50. However, early diagnosis and start of treatment of FH can ameliorate the disease's negative long term effects. The Swedish National Board of Health and Welfare gave in its guidelines from 2015 a high priority to the work of identifying and diagnosing individuals with FH in the general population. The introduction of the ICD-10 code E78.0A for FH may, when properly used, be an effective tool in this work.
