In today’s fast-paced world, it’s easy to grab convenient snacks without considering their long-term effects on our health. However, what we eat has a profound impact on our brain health, affecting everything from cognitive function to the risk of developing neurodegenerative diseases. Neuroscientist Dr. Robert Love emphasises the importance of being mindful about our snack choices, highlighting that some seemingly harmless foods can be particularly detrimental to brain health. By understanding the specific dangers of these snacks and making better dietary choices, we can take proactive steps to protect our brains and overall well-being.
Consuming a diet rich in inflammatory and sugary foods can increase the risk of conditions like Alzheimer’s disease, which is now understood to have a significant dietary component. Dr. Love, in a recent TikTok video, points out that certain snacks we might consider harmless or even healthy can be particularly bad for our brains. Among these, three snacks stand out due to their potential to cause inflammation, spikes in insulin, and overall poor nutritional quality. By avoiding these snacks, we can significantly improve our brain health and reduce the risk of cognitive decline. The three snacks Dr. Love advises avoiding, first shared in an interview at She Finds, are peanut-butter filled pretzels, potato chips, and breakfast cereals.
Peanut-Butter Filled Pretzels
The first snack to avoid is peanut butter filled pretzels. While they might seem like a healthy option due to the peanut butter content, Dr. Love explains that these snacks pose several risks. The primary issue is the quality of the peanut butter used, which is typically low-grade and inflammatory. Inflammation is one of the primary risk factors for Alzheimer’s disease. Additionally, the vegetable oils used in the peanut butter, such as canola oil, can cause further inflammation. The pretzels themselves contain gluten, which also contributes to inflammation. These combined factors make peanut butter filled pretzels a snack to avoid if you are concerned about your brain health.
The danger with peanut butter filled pretzels lies not just in the individual components, but in their combination. Low-grade peanut butter often contains added sugars and hydrogenated oils, which are detrimental to both cardiovascular and brain health. The gluten in pretzels can cause adverse reactions in those with gluten sensitivities or celiac disease, leading to gut inflammation that can affect brain function through the gut-brain axis. Choosing high-quality, natural peanut butter without added sugars or oils and pairing it with gluten-free options can be a better alternative.
Potato Chips
Another common snack that should be avoided is potato chips. Dr. Love highlights that potato chips are not only extremely salty but also surprisingly high in sugar. The excessive salt content can increase blood pressure, while the high sugar content can lead to spikes in insulin and blood glucose levels. These spikes can increase the risk of type two diabetes, a major risk factor for Alzheimer’s disease. All in all, potato chips are a particularly harmful snack for brain health due to their high levels of salt and sugar, along with their potential to cause significant insulin and blood glucose spikes.
Potato chips are also problematic because of the way they are processed. They are often fried in unhealthy oils that can produce trans fats and other harmful compounds. These fats can increase bad cholesterol (LDL) and decrease good cholesterol (HDL), which is detrimental to cardiovascular health and, by extension, brain health. Moreover, the high glycaemic index of potato chips means they are rapidly converted into glucose, causing quick spikes in blood sugar that can lead to insulin resistance over time. Opting for baked or air-fried vegetable chips with minimal added salt and oil can be a healthier choice.

Breakfast Cereals
Lastly, breakfast cereals, often marketed as healthy choices, are another snack to be wary of. Dr. Love points out that most breakfast cereals are high in sugar, which spikes insulin and increases the risk of type two diabetes. Many cereals also contain wheat, which includes gluten. Gluten increases inflammation, further contributing to the risk of Alzheimer’s disease and other inflammatory conditions. The combination of high sugar and gluten content makes breakfast cereals a poor choice for maintaining brain health. Opting for cereals that are low in sugar and free from gluten can help mitigate these risks.
The issue with breakfast cereals is often hidden under the guise of health claims on their packaging. Terms like “whole grain,” “fortified,” and “high-fibre” can be misleading if the cereal also contains high amounts of added sugars and artificial ingredients. These additives can cause blood sugar spikes and crashes, leading to poor concentration and mood swings. Furthermore, the processing methods used to make cereals can strip away essential nutrients, leaving behind empty calories. A better option is to choose whole foods like oatmeal or homemade granola made with nuts, seeds, and natural sweeteners like honey or fruit.
Conclusion
Dr. Love’s insights underscore the importance of being mindful about our snack choices. The inflammatory properties of certain foods, coupled with their ability to spike insulin and blood glucose levels, can significantly increase the risk of Alzheimer’s disease and other health issues. By avoiding peanut butter filled pretzels, potato chips, and sugary breakfast cereals, you can take a proactive step towards maintaining your brain health. Instead, consider opting for snacks that are low in sugar, free from gluten, and made with high-quality ingredients.
Making these changes doesn’t mean you have to sacrifice flavour or enjoyment. There are plenty of delicious and nutritious snack alternatives available. For example, you can enjoy fresh fruits, nuts, and seeds, which provide healthy fats, proteins, and essential vitamins and minerals that support brain health. Additionally, incorporating more whole foods into your diet can help stabilize blood sugar levels, reduce inflammation, and promote overall well-being. By making informed choices, you can protect your brain and enhance your cognitive function for years to come.
