There are a lot of recommendations for a ketogenic diet now, as a way of promoting health.
Eating a ketogenic diet means that you eat a very high-fat diet.
You can also find recommendations for consuming a lot of saturated fat.
We have known about the effect of fat for quite some time.
Let’s see what the research says. This is both interesting and important.
This study investigated the association between fat intake and incident of dementia among participants who were 55 years old or older (Kalmijn S, et al.,1997).
The researchers assessed the food intake of 5,386 participants without dementia at the start of
After an average of 2.1 years of follow-up, they screened for dementia with a three-step protocol
that included a clinical examination. This is what the researchers found.
Dementia with a vascular component was most strongly related to total fat and saturated fat
Fish consumption, an important source of omega 3 fatty acids, was related to a reduced
risk of dementia, especially Alzheimer's disease.
High saturated fat and cholesterol intake increased the risk of dementia.
Consuming a lot of fish with all the contamination of fish we have now is not the healthiest way
to increase the intake of omega 3 fatty acids. There is even more pollution now compared to
when the research was published which was in 1997.
If you instead take omega 3 fish oil capsules, you can avoid a lot of these toxins and still get the
benefits of omega 3 fat.
The fish oil needs to be a high-quality product, that’s important, and it should contain high amounts of EPA and DHA which are the active ingredients of Omega 3 fat.
