Trans fats, also known as partially hydrogenated oils, have long been known to have negative effects on physical health, such as increasing the risk of heart disease and stroke.
However, recent research has shown that trans fats may also have an impact on cognitive health, specifically memory loss.
What Are Trans Fats?
Trans fats are created when liquid vegetable oils are processed into solid fats through a chemical hydrogenation process.
This process increases the shelf life of foods and makes them more stable at high temperatures, which is why trans fats are commonly found in many processed foods, such as baked goods, snack foods, and fried foods.
Effects of Trans Fats on Physical Health
Trans fats have been linked to numerous negative health effects, specifically on physical health. Eating trans fats can increase bad cholesterol (LDL) levels while decreasing good cholesterol (HDL) levels in the body.
This leads to a buildup of cholesterol in the arteries, increasing the risk of heart disease and stroke.
The Connection Between Trans Fats and Memory Loss
Recent studies have shown that trans fats may also have an impact on cognitive health, specifically memory loss.
A study published in the journal PLOS ONE found that people with higher levels of trans fats in their blood had worse memory function and smaller brain volume compared to those who had lower levels of trans fats. The study also found that those who consumed more trans fats had poorer cognitive performance on tests that measured cognitive flexibility and processing speed.
Another study published in the journal Neurology found that people who consumed high levels of trans fats had worse cognitive function over time compared to those who consumed lower levels of trans fats.

This decline in cognitive function was specifically seen in tests that measured language ability, attention, and memory.
How Trans Fats Affect the Brain
It is currently unclear how trans fats affect the brain and lead to memory loss. However, it is thought that trans fats may cause inflammation in the brain, which can lead to damage to brain cells and negatively impact brain function.
Inflammation in the brain has also been linked to the development of neurodegenerative diseases, such as Alzheimer’s disease.
How to Reduce Trans Fat Consumption
The good news is that eliminating trans fats from your diet is relatively easy. The first step is to read food labels and avoid foods that contain partially hydrogenated oils.
These include baked goods, fried foods, snack foods, and some margarines and shortenings.
Eating a diet rich in whole foods, such as fruits, vegetables, whole grains, and lean protein, can also help to reduce your intake of trans fats.
Cooking at home with healthy oils like olive oil and canola oil, rather than using highly processed oils, is also a good way to avoid consuming trans fats.
The Bottom Line
Trans fats have long been known to have negative effects on physical health, but recent research has shown that they may also have an impact on cognitive health and memory loss.
While more research is needed to fully understand the connection between trans fats and memory loss, it is clear that reducing trans fat consumption is an important step in maintaining both physical and cognitive health.
