You are probably aware of the effect your diet has on your waistline. But did you know that your diet also plays an important role in your cognitive abilities? Studies show that there is a strong link between nutrition and cognitive development. A healthy diet can lower the risk of dementia, while bad dietary habits could lead to cognitive decline and increase the risk of brain diseases like Alzheimer’s.

Link Between Diet and Cognitive Decline


Dementia, which is primarily characterized by cognitive decline, affects a large number of people every year. It is estimated that the problem could affect as many as 130 million people globally by 2050.

One of the reasons why Alzheimer’s and other such forms of dementia are becoming increasingly common these days is our dietary habits. Many of us regularly eat processed food, which contains trans fats, nitrites, and a number of other substances that are known to increase the risk of memory loss and cognitive impairment considerably.

Given here is a list of 10 ingredients that are commonly found in the food that we eat and are known to increase the risk of Alzheimer’s significantly.

Trans Fats

Trans Fats

Trans fats are harmful not just for your heart, but also for your brain. They clog your arteries and deprive your brain of oxygen. They prevent the formation of apolipoprotein E, which is an essential protein which regulates the amyloids in the brain. Without apolipoprotein E, the amyloids in your brain tend to stick together and form clumps and plaques, which affect neuron function and lead to cognitive impairment.

Unfortunately, almost all the fried and baked goods that you can find on the market today contain trans fats. As a rule of thumb, it is a good idea to avoid anything that contains partially hydrogenated oil, which is the main source of trans fats in most food items.
