- People with familial hypercholesterolemia (FH) are at greater rish of heart disease
- At least 1 in 500 people are believed to have FH but may be more as in other European countries
- Of the 120,000 people in the UK with FH only 15% – less than 1 in 5, know they have the condition
- At least 28,000 children in the UK have FH but only 600 of these are known
The myth of dietary cholesterol
Everyone knows that egg yolk is rich in cholesterol. It’s needed for the young chick to develop and grow. But one of the most common questions we get asked on the HEART UK Cholesterol Helpline is “If I have high cholesterol can I eat eggs?
HEART UK’s advice on this sticky question has always remained the same. For the majority of people with raised cholesterol there is no reason to limit cholesterol containing foods that are otherwise low in saturated fat. Why? Because the focus of our dietary advice is to lower saturated fat and replace it with healthy calories from unsaturated fats and wholegrain foods. This is because saturated fat has a greater influence on cholesterol levels than eating the foods that contain cholesterol.
So where has the advice to restrict eggs come from?
The myth that dietary cholesterol is to blame for raised blood cholesterol has been around for some time. It has even infiltrated dietary guidelines. In particular the USA have long advised the restriction of dietary cholesterol to below 300mg per day. However last year their advisory committee said that cholesterol restriction was not necessary and that instead saturated fats are to blame for high cholesterol. Their report provides the basis for the updated 2015 Dietary Guidelines from the U.S. Department of Agriculture.
So what of UK Dietary Guidelines? UK Dietary Guidelines don’t recommend a cholesterol restriction. However there is one exception: Clinical Guideline 71 (CG71) - Identification and management of familial hypercholesterolaemia (FH) recommends dietary cholesterol should be restricted to less than 300mg per day. This is in line with HEART UK advice for people with FH. Why? Well, even though dietary cholesterol has only a small effect on blood cholesterol, for people with FH a modest of dietary cholesterol seems sensible.
Where is dietary cholesterol found?
All animal foods contain some dietary cholesterol, but eggs, shellfish and organ meats are particularly rich sources of cholesterol.
|Foods that are rich in saturated fat and contain cholesterol||Foods low in saturated fat but rich in cholesterol|
Full cream dairy foods such as milk, cheese, yoghurt, cream
Animal fats - butter, ghee, margarines and spreads made from animal fats, lard, suet, dripping
Fatty meat and processed meat products
Lean meat especially offal: liver, kidney, sweetbreads, heart, tripe
Prawns, crab, lobster, squid, octopus, cuttlefish
|Following a cardio-protective diet (low in saturated fat) will naturally restrict cholesterol from these sources||Most people do not need to restrict these foods|
So the good news is that most of us don’t need to worry about having an egg for breakfast, or enjoying shellfish more often. In fact according to UK dietary surveys our average cholesterol intake is only around 300mg per day anyway. Of more concern is our saturated fat intake which continues to exceed UK Dietary Recommendations.
A word about Liver
Liver is a lean meat and a great source of vitamins and minerals such as iron, copper, zinc, and vitamins A, B and D. In fact the levels of vitamin A are so high that there are concerns that regular consumption could lead to a build-up of vitamin A in the body and cause problems in some groups of the population.
The Department of Health advice is to limit liver and liver pate to no more than one portion per week and (if you do eat liver) to avoid any supplements that also contain A in the form of retinol. Pregnant women or those planning to conceive should avoid liver, liver pate and retinol containing supplements completely. Visit the Department of Health guidance on liver.
