The Prevalence of Ultra-Processed Foods and Its Impact on Chronic Diseases
Ultra-processed foods, which make up a significant portion of the food environment, have been linked to an increased risk of chronic diseases, including early mortality and dementia. These foods are designed to be hyper-palatable and are not meant to be consumed in moderation. Consuming a high amount of ultra-processed foods has been associated with a 14% increased risk in early mortality for every 10% increase in consumption. The risk of dementia is also elevated with a 25% increase for the same consumption increase. These foods have a long shelf life and are often low in protein, fiber, and water, making them less satiating. They tend to be high in added sugars and refined grains, which contribute to metabolic dysfunction and obesity. Reducing the consumption of ultra-processed foods is crucial for promoting optimal health.
The Impact of Refined Seed Oils on Health
Refined seed oils, such as canola, corn, soybean, and grape seed oil, are commonly used in processed foods and cooking. These oils have raised concerns due to their high omega-6 fatty acid content and chemical instability. Studies suggest that these oils may contribute to inflammation, obesity, metabolic dysfunction, and brain health issues. It is advisable to minimize consumption of these oils and instead opt for healthier options like extra virgin olive oil, which is associated with cardiovascular protection and brain health benefits. These oils, when used in restaurant settings, may undergo chemical degradation due to oxidation, making them potentially harmful. Being mindful of the quality of oils consumed is important for overall health and well-being.
The Importance of Reducing Added Sugar Intake
Added sugar consumption has reached alarming levels, with adults averaging about 77 grams (19 teaspoons) of added sugar per day. High sugar intake is associated with various health issues, such as obesity, type 2 diabetes, hypertension, and cognitive decline. Excess sugar consumption contributes to hyperpalatability, promotes overeating, and can lead to hormonal imbalances. The World Health Organization and various health organizations recommend limiting added sugar intake. Being mindful of added sugar content in food labels and reducing consumption can significantly contribute to better overall health and brain function.
Understanding Modifiable Risk Factors for Dementia Prevention
Dementia was previously considered an uncontrollable part of aging, but research now suggests that it is a potentially preventable condition. The Lancet Commission on Dementia identified 12 modifiable risk factors, including obesity, type 2 diabetes, hypertension, physical inactivity, smoking, depression, hearing loss, social isolation, low educational attainment, excessive alcohol consumption, air pollution, and traumatic brain injury. Taking steps to address these modifiable risk factors through lifestyle changes can significantly reduce the risk of developing dementia. It is important to recognize that genes alone do not determine one's destiny, and that diet, exercise, and overall health play a crucial role in brain health and cognitive function.
The Benefits of Avocado for Brain Health
Avocados are rich in fat-protecting antioxidants, which are crucial for reducing oxidative stress and aging in the brain. They contain fat-soluble antioxidants like vitamin E and carotenoids, which help protect the brain against oxidative stress and promote cognitive function. Avocado is considered a genius food because it provides the highest proportion of fat-protecting antioxidants among fruits and vegetables.
The Importance of Dark Leafy Greens in Brain Health
Dark leafy greens, such as kale, spinach, and arugula, are nutrient-dense and have numerous brain health benefits. They are rich in fat-soluble antioxidants like vitamin E, which protect the brain from oxidative stress and support healthy aging. Dark leafy greens also contain carotenoids like lutein and zeaxanthin, which accumulate in the brain and are associated with reduced cognitive aging and improved brain function. Consuming dark leafy greens as part of a fatty salad with extra virgin olive oil enhances the absorption of these beneficial nutrients.
The Value of Animal Products in Brain Health
Animal products, including fish, dairy, eggs, and beef, provide important nutrients for brain health. Fish is a great source of omega-3 fatty acids, which support brain structure and function. Dairy products like Greek yogurt and whole milk are rich in protein and micronutrients, including calcium and magnesium. Eggs are a nutrient powerhouse, containing cholesterol, choline, and various vitamins that support brain development and function. Grass-fed beef is highly nutritious, providing protein, creatine, taurine, and other important nutrients. Animal products, when sourced and consumed responsibly, can be part of a nutrient-dense diet that promotes brain health.
Importance of Personalized Diets
Personalized diets are crucial as there is no one-size-fits-all approach to nutrition. Different individuals have different health conditions, goals, and circumstances. While some may thrive on the carnivore diet, others may benefit from following a vegan or paleo diet. The key is to find a dietary approach that works for one's specific needs and to be open-minded about trying different options. Long-term studies are lacking, but the focus should be on finding what improves individual health rather than dismissing other research or recommendations.
Balancing Personal Choices and Informed Consent
Personal choice and informed consent are essential when it comes to dietary decisions. It is possible to have a healthy brain function without consuming animal products, although careful planning and supplementation may be necessary. People have the right to follow their ethical beliefs or personal preferences when it comes to food choices. However, it is crucial to be aware that there can be indirect consequences and impacts associated with different dietary decisions, as modern agriculture can lead to the death of animals and environmental damage. Making informed decisions and continuously evaluating choices can lead to better health outcomes.
My guest today is on a mission to help people feel better, live longer, and maximise their brain health by optimising their diet. Max Lugavere is a science journalist and a New York Times bestselling author. He believes brain decline is not inevitable, we all have agency in how we age, and the secret lies in our food. This drive began following his mother’s diagnosis with Lewy body dementia aged just 58, and his frustration at the medical world’s ineffective, drugs-only approach to treatment. Years spent trawling the research and asking experts, “Why her?” has given him a wealth of knowledge that he is keen to share with others.
Through his books Genius Foods, The Genius Life, and cookbook Genius Kitchen, as well as a long-running podcast, Max shares evidence-based principles that will help all of us protect our brains. And his passion, along with an encyclopaedic ability to recall and communicate the science, is why I really wanted to talk to Max on my show.
Max talks us through the three food types we should think about cutting out – and why. We discuss ultra-processed foods and why it’s not in our nature to consume them in moderation. He explains the wholefood matrix, and the protective synergy that comes with eating foods, in a minimally processed state. If you’ve ever wondered about the healthiest fats to cook with, Max covers this in detail.
He also shares which specific foods he recommends we all include in our diets and what brain-healthy nutrients they provide. Perhaps controversially, we discuss the adage ‘Everything in moderation’ and why this might not be the healthiest approach. If we’re going to declare some foods good, says Max, other foods must therefore be bad. And within the context of a sick population, surely we should be bolder about advising people to quit the food types we know are unnatural and harmful?
Having experienced the trauma of his mother’s illness, Max isn’t bothered about the critics, he’s just really keen to help people. He’s an advocate for informed consent, sharing facts to enable us to make tailored, better food choices. Above all, his message is one of balance and realism. We can all make choices every single day that set us on the path to better health, even if we’re only taking baby steps. I immensely enjoyed my conversation with him. I hope you enjoy listening.
