📚 Introduction

The food we eat has a significant impact on our brain health and cognition. In this blog post, we will explore the various ways in which food influences our brain function and discuss actionable tips for improving our diet to support optimal brain health.

🔍 Wisdom Unpacked

Delving deeper into the key ideas.

1. Understanding gut, metabolic, and belief signals can guide healthier food choices.

The brain's health and cognition are influenced by the food we consume. The three major signals that drive our food choices are gut signals, metabolic accessibility, and beliefs. Gut signals are subconscious and come from neurons in our gut, while metabolic accessibility refers to how easily a food can be converted into energy for our brain. Beliefs about the health benefits of a food can also influence our choices. By understanding these signals, we can change what we eat and drive our brain and body to crave healthier options.

2. Time-restricted feeding, with a consistent feeding window, benefits health.

Time-restricted feeding, also known as intermittent fasting, has several key elements that benefit health. The feeding window should begin at least one hour after waking and end at least two hours before going to sleep. It is recommended to keep the feeding window at the same phase each day. Starting and ending the feeding window at different times each day can disrupt the body's clock genes, which regulate various processes.

3. Enhance brain function with essential fatty acids, phosphatidyl serine, choline, and proper hydration.

Enhancing brain function and maintaining brain health requires a focus on certain foods and avoidance of others. Quality sleep and cardiovascular health are crucial. The glia, a type of brain cell, play an active role in brain function, and essential fatty acids and phospholipids, particularly EPA and DHA, are important for brain health. Omega threes, found in fish, chia seeds, walnuts, and soybeans, can be supplemented to support brain function. Phosphatidyl serine, found in meats and fish, supports neuronal function, and choline, found in eggs, potatoes, nuts, seeds, grains, and fruit, enhances focus and alertness. Maintaining proper hydration and electrolyte intake is also essential for brain function. These compounds support brain function and are important for maintaining overall brain health.

4. Creatine, blueberries, and glutamine enhance brain function and health.

Creatine, a compound found in meat sources or supplements, can enhance brain function, particularly in mood regulation and motivation. It can also aid in mild depression. Blueberries, rich in anthocyanins, can improve brain function, reduce cognitive decline, and enhance memory. Glutamine, an amino acid, can enhance immune system function, reduce inflammation, and offset sugar cravings. It can also offset the negative effects of altitude on cognition. These supplements can be beneficial for cognitive function and overall health.

5. Understanding brain-food interactions can help rewire preferences and promote healthier choices.

Our brain health is influenced by the foods we eat, with three channels determining our food preferences: taste, sensors on our tongue, and the insular cortex. These channels can be influenced by selectively silencing or activating neurons in the brain, demonstrating that perception of taste is a central phenomenon within the brain. Our body and brain work together to make us prefer certain foods, with neurons in our digestive tract and gut microbiome playing a significant role. A third pathway in our brain associates a particular taste with the quality or value of a food, which can be leveraged to rewire our preferences and seek healthier foods. Understanding this can help us change our relationship with certain foods. Our subjective thoughts about food can impact how we perceive its taste and how our body utilizes it. Studies have shown that our beliefs about a food's nutritional value can influence our physiological response, such as blood sugar and insulin levels.

6. Fermented foods are the simplest way to get probiotics.

The simplest and most straightforward way to get probiotics is through fermented foods, which have been consumed for their taste and health benefits for thousands of years. There are two mechanisms that influence our preference for certain foods: the taste on our tongue and the sensations in our mouth, and subconscious signaling from the gut based on the nutrient content of the foods. However, supplementing with capsule form probiotics may not contain the correct prebiotics and probiotics for setting the correct gut microbiota conditions.

7. Biological circuits can be hardwired or softwired, adapting to changing needs.

Biological and neuroscientific circuits can be either hardwired or softwired. Hardwired circuits are immutable, while softwired circuits can change. For instance, the brain's speech and language areas are always in the same place but can adapt to different languages. Similarly, the taste system is hardwired to seek certain nutrients, but it can also adapt to different tastes.

8. Artificial sweeteners can disrupt blood sugar management and insulin glucose system.

Artificial sweeteners can rewire our taste system and lead to a conditioned preference for them, even if they don't raise blood glucose levels. This is because dopamine levels eventually start to rise, reinforcing the consumption of artificial sweeteners. However, when artificial sweeteners are paired with substances that increase blood glucose, such as consuming diet soda with food, it can lead to alterations in blood sugar management. This is because the combination of the artificial sweetener and the increase in blood glucose triggers a response in the dopamine system, resulting in increased insulin secretion. Consuming artificial sweeteners alone or in combination with foods that raise blood glucose levels can disrupt blood sugar management and insulin glucose system. It is best to consume artificial sweeteners away from foods that raise blood glucose levels. The gut microbiome may also be affected by certain artificial sweeteners, influencing the preference for certain foods and the activation of the dopamine system.

9. Condition your brain to prefer healthy foods for better brain health.

To incorporate healthy foods into your diet, focus on consuming foods that are good for your brain health, even if they don't taste good to you. Pair these foods with foods that provide a shift in brain metabolism, such as ketones for keto diet or plant-based foods for a plant-based diet. By doing this, you can condition your brain to prefer these healthy foods within a short period of time, around 7-14 days. This has important implications for the controversy and food wars in the nutrition realm. What we consume regularly becomes reinforcing and can explain why certain diets feel good and are heavily subscribed to. While certain foods and micronutrients may be better or worse for us, it's important to recognize that foods impact our brain and its health, as well as how our brain functions and responds to food. We can adjust our perception of attractive and rewarding foods by consuming foods that are less sweet or savory.

💡 Actionable Wisdom

Transformative tips to apply and remember.

To improve brain health through diet, focus on consuming foods that are beneficial for the brain, such as omega-3 fatty acids, essential amino acids, and probiotics. Avoid artificial sweeteners and prioritize whole, unprocessed foods. Additionally, consider incorporating time-restricted feeding into your routine to optimize brain function. By making these dietary changes, you can enhance your cognitive abilities and support long-term brain health.
