Harvard discovers the 5 foods that “ruin” your memory

An expert nutritionist Harvard University detailed certain foods whose disproportionate consumption can cause a problem with memory or the ability to concentrategiving rise to a list of five brought together in a report of The Economist.

He’s the nutritional psychiatrist Uma Naidoowhich develops research aimed at studying the impact of dietary changes on mental health or mood, as well as the impact of diet or certain types of food on the human brain.

As noted in the aforementioned information, Naidoo is aware that some of the following five foods are very difficult to completely eliminate from a diet, but undertakes to moderate its consumption to avoid possible long-term consequences on the brain.

Industrial oils

The first of the foods to avoid corresponds to highly processed oils, for example from soya, corn, rapeseed and cotton seeds, or even sunflower and safflower. The reason is that they contain high levels of omega-6 fatty acids. It can be replaced with avocado, coconut or olive oil.

refined sugars

Added and refined sugars can ultimately cause excess glucose in the body, which could result in memory deficits and decreased plasticity of the hippocampus. To do this, the nutritionist undertakes to replace products with added sugars – sauces for example – with homemade products.

Processed foods

In addition, all processed or ultra-processed foods suffer from shortening of telomeres – the ends of chromosomes –. This process affects cells, causing them to age less healthily than they normally would. “If you can’t pronounce an ingredient, or have no idea what it is, then it’s generally best to avoid it,” the expert advises directly.

Artificial sweeteners

Other foods to avoid are artificial sweeteners like saccharin, sucralose or stevia. They lack nutritional value and their consumption can affect the number of “bad” bacteria that live in the belly. Note that they are easily replaced by foods such as honey.


Perhaps the best known. Foods that have been fried in a lot of oil, have a crust, or are coated in batter can end up being harmful to the brain if consumed excessively. A great alternative is to bake what is going to be fried in the fryer.
