This amount of bacon poses risks to brain health, according to science

Starting the day with a crispy slice of bacon may seem harmless. But science has shown that this habit, so common in countries like the United States, can have serious long-term consequences—ranging from high blood pressure to a higher risk of cancer and even harm to brain health.

What makes bacon a risk?

Bacon is part of the processed meat group, also known as sausages. This means it undergoes salting, curing, smoking, and preservatives, which increases its shelf life and flavor, but also contains saturated fats, sodium, nitrite, and nitrate—compounds linked to cardiovascular disease, cancer, and metabolic disorders.

According to studies, consuming just 50g of bacon daily is enough to increase the risk of colorectal cancer by 18%. According to the World Health Organization (WHO), there is no safe limit for processed meats.

Impact also on brain health

The warning goes beyond the gut. A study published in the journal " Neurology ," conducted by experts at Brigham and Women's Hospital in partnership with the Harvard T.H. Chan School of Public Health, showed that even 25g per day—the equivalent of a single slice of bacon—increases the risk of developing dementia by 13%.

This is because processed meats contain compounds capable of causing inflammation and cellular damage, including in the brain. Frequent consumption is associated with changes that can silently sabotage cognitive health over time.

Protective alternatives

The same study found that replacing a daily serving of bacon with healthy foods like nuts, legumes, or fish can reduce the risk of dementia by up to 20%. These foods provide good fats, antioxidants, and nutrients that promote brain health.

Another study, conducted by the University of Washington, reinforces the concern: even a daily serving of processed meats can increase the risk of bowel cancer and diabetes.

What to prioritize on your plate

To maintain good health—including brain health—processed meats should ideally be consumed only occasionally. The basis of your diet should be natural or minimally processed foods, such as:

•Various fruits and vegetables •Whole grains (oats, chia, flaxseed) •Oilseeds (walnuts, chestnuts) •Legumes (beans, lentils, chickpeas) •Natural yogurts

•White meat and fish

Therefore, while tasty, bacon is one of the foods most recommended in moderation. Science shows that even small amounts, when consumed daily, can have a negative impact on intestinal, cardiovascular, and even brain health.
