High cholesterol intake not tied to memory disorders

High cholesterol intake not tied to memory disorders

Researchers at the University of Eastern Finland have found no link between high cholesterol intake and an increased risk of dementia or Alzheimer's disease.

The study also found there was no association in people who carry the APOE4 gene variant that affects cholesterol metabolism and increases the risk of memory disorders, UPI reported.

A relatively high intake of dietary cholesterol is the equivalent of eating one egg per day. Dietary cholesterol affects serum cholesterol levels only slightly in the majority of the population and there are no longer set limitations on the intake of dietary cholesterol.

Serum cholesterol consists of high-density lipoprotein, or HDL, low-density lipoprotein, or LDL, and triglycerides.

High serum cholesterol levels have been associated with an increased risk of cardiovascular diseases along with memory disorders.

In carriers of APOE4, dietary cholesterol has a visible effect on serum cholesterol levels. Finland has a high prevalence of APOE4 with roughly one-third of the population being carriers.

The research found that a high intake of dietary cholesterol was not linked with a risk of dementia or Alzheimer's disease for the entire study population or the carriers of APOE4.
