The modern diet, with its heavy reliance on processed foods and seed oils, has been a topic of concern for health-conscious individuals. Understanding the impact of these dietary choices, particularly the effects of seed oils on health, is crucial. In this blog, we’ll delve into three significant ways that processed foods and seed oils can detrimentally impact your health.
1. Brain Health and Cognitive Function
A diet high in processed foods and seed oils, especially those rich in linoleic acid like sunflower oil, can have profound effects on brain health. Studies have shown that diets low in alpha-linolenic acid result in reduced levels of docosahexaenoic acid (DHA) in brain cells. DHA is essential for the maintenance of nerve membrane composition and enzymatic activity. Reduced DHA levels can lead to compromised learning performance and cognitive function. This effect is especially concerning in the context of children’s diets, where proper brain development is critical.
2. Link to Aggressive Behavior and Mental Health
An intriguing yet alarming aspect of high seed oil consumption is its potential link to behavioral changes. Research indicates a correlation between high dietary intakes of linoleic acid from seed oils and increased rates of homicide mortality. This finding suggests that our diet could be influencing our behavior and mental health in more profound ways than previously thought. The exact mechanisms are still under investigation, but this association points to the need for a deeper understanding of how dietary fats influence not just our physical health but our psychological and social behaviors as well.
3. Chronic Inflammation and Disease Risk
One of the most significant impacts of excessive seed oil consumption is its role in promoting chronic inflammation. Seed oils high in linoleic acid contribute to low-grade inflammation, a precursor to numerous chronic diseases including cardiovascular disease, certain cancers, and potentially even diabetes. Linoleic acid can activate pro-inflammatory pathways, thereby increasing the risk of coronary heart disease. Moreover, the shift in our diets over the last century towards higher intake of these oils has led to a dramatic increase in linoleic acid concentration in human fat tissue, reflecting the profound changes in our dietary patterns.
4. The Deception of Processed Carbohydrates
Processed carbohydrates, found in foods like bread, pasta, cereals, and snacks, are often masqueraded as healthy options. However, they are far from it. These carbohydrates are not only derived from plant seeds full of defense chemicals but are also highly processed, stripping away any nutritional value. They contribute to metabolic damage, spiking blood sugar levels and leading to a cascade of health issues. The lack of essential nutrients in these processed foods exacerbates the problem, leaving the body deprived of the building blocks it needs for optimal function.

5. The Hidden Perils of Seed Oils
Seed oils, such as canola, sunflower, corn, soy, and cottonseed oils, are often touted as healthy fats. But this is a dangerous misconception. These polyunsaturated fats, high in linoleic acid, are not suitable for human consumption in the quantities found in the modern diet. Excess linoleic acid in the body can disrupt normal fat cell function, leading to inflammation, insulin resistance, and DNA damage. This process is a significant contributor to chronic diseases, yet it is often overlooked.
6. The Surprising Sources of Linoleic Acid
It’s not just processed foods and seed oils that are culprits in the overconsumption of linoleic acid. Many “healthy” nuts and seeds, along with chicken and pork (which store linoleic acid in their fat), also contribute to this excess. The stark contrast between our ancestors’ diet, which included very little linoleic acid, and the modern diet, where it can constitute up to 20% of total calories, highlights the severity of the issue.

7. Returning to a Species-Appropriate Diet
To reclaim our health, it’s vital to revert to a diet more aligned with our evolutionary history. This means eliminating processed foods and focusing on well-raised ruminant meats, organs, fruits, honey, and raw dairy. Saturated fats from these sources are more appropriate for human consumption, providing the right balance of nutrients without the harmful effects of excess linoleic acid.
8. The Power of Choice in Diet
The choice of what we eat has far-reaching implications for our health. By selecting foods that are closer to what our ancestors consumed, we can mitigate the risks associated with modern dietary practices. This isn’t just about avoiding illness; it’s about thriving. It’s about honoring our biological heritage and giving our bodies what they need to function optimally.
The modern diet, with its heavy reliance on processed carbohydrates and seed oils, is a far cry from what our bodies are designed to consume. This is supported in studies analysed by Paul Salindino MD. By understanding the harmful effects of these components and making conscious dietary choices, we can protect ourselves from chronic diseases and embrace a state of true health and vitality. Remember, every bite is a choice – choose for your health. For more insights on the specific health benefits of avoiding seed oils, click here.
