Improving your diet can significantly impact decision-making by enhancing brain function, mood, and energy levels. Here are ten actionable pieces of advice to help you eat better and improve your decision-making abilities.
Eating and sleeping better can increase your cognitive abilities and are the basis for good decisions daily. As a rule of thumb, every day, aim to have 7.5 or 9 hours of sleep (90-minute increments) and three primary meals of unprocessed foods (as much as possible). A healthy meal plan and good sleep go hand-in-hand. See my Sleep Better for Career Growth companion article with 10 actionable steps to enhance your sleeping.
Step 1 — Incorporate Omega-3 Fatty Acids
Omega-3 fatty acids, particularly EPA and DHA, are crucial for maintaining brain health and function. These fats help build and repair brain cells, and their anti-inflammatory properties can protect against brain ageing and cognitive decline. Incorporating omega-3-rich foods, like fatty fish (salmon, mackerel, sardines), and plant-based sources like walnuts, flaxseeds, and chia seeds, can improve aspects of cognitive function related to decision-making and problem-solving. Considering an omega-3 supplement (after consulting with a healthcare provider) can benefit individuals who do not consume fish.
Step 2 — Stay Hydrated
Water is essential for the brain’s electrical energy, which is necessary for all brain functions, including thought and memory processes. Even mild dehydration can affect cognitive function, leading to difficulty concentrating, making decisions, and remembering information. Drinking water regularly throughout the day can prevent dehydration. Water-rich foods like cucumbers, tomatoes, and watermelon can contribute to hydration and aid cognitive functions.
Step 3 — Eat More Whole Foods
Whole foods provide a symphony of nutrients that work together to support brain health. For example, leafy greens contain folate, vitamin E, and carotenoids, which are linked to lower levels of cognitive decline. Berries offer antioxidants that can improve communication between brain cells. Whole grains provide a steady energy supply to the brain, enhancing focus and decision-making capabilities. Incorporating various foods ensures a broad intake of nutrients essential for brain health.
Step 4 — Limit Added Sugars
High intake of added sugars can lead to a roller-coaster effect on blood sugar levels, impairing brain function and mood stability and affecting your ability to make sound decisions. Foods high in added sugars can also contribute to inflammation and oxidative stress, potentially harming brain cells. Limiting the consumption of sugary snacks, beverages, and processed foods can help maintain optimal brain function and decision-making capabilities.
Step 5 — Prioritize Breakfast
Breakfast provides the brain with an initial supply of glucose, the brain’s preferred energy source. A nutritious breakfast sets the tone for the day, stabilizing blood sugar levels and providing the nutrients necessary for optimal brain function. Including protein and fibre in your breakfast can help prevent mid-morning slumps and maintain focus and decision-making abilities throughout the day.
Step 6 — Incorporate Antioxidant-Rich Foods
Antioxidants protect the brain from damage caused by free radicals, potentially reducing the risk of cognitive decline. Foods rich in antioxidants, such as berries, nuts, and green leafy vegetables, protect brain cells and improve communication between neurons, which is vital for decision-making and problem-solving. Regularly consuming various foods can enhance brain health and cognitive function.
Step 7 — Moderate Caffeine Consumption
Caffeine stimulates the central nervous system, enhancing alertness, concentration, and mood, positively affecting decision-making. However, excessive caffeine intake can lead to adverse effects such as anxiety and sleep disturbances, which can impair cognitive function. Finding the right balance in caffeine consumption can optimize its mental benefits without the drawbacks, enhancing decision-making abilities.
Step 8 — Limit Alcohol
While moderate alcohol consumption can have social and possibly health benefits, excessive drinking is detrimental to brain health, affecting cognitive functions, including decision-making and impulse control. Limiting alcohol to recommended levels and having alcohol-free days can minimize its negative impact on brain function and decision-making abilities.
Step 9 — Maintain a Balanced Diet
A diet that includes a mix of carbohydrates, proteins, and fats ensures the brain receives a wide range of nutrients needed for its function. Carbohydrates provide glucose, proteins supply amino acids that are precursors to neurotransmitters, and fats contribute essential fatty acids. A balanced diet supports neurotransmitter function, brain cell structure, and cognitive processes, including decision-making.
Step 10 — Plan Your Meals
Meal planning is a proactive approach to nutrition that ensures you consume a diverse range of nutrients necessary for brain health. It helps make informed food choices, avoid impulsive or unhealthy eating habits, and provide regular food intake that supports cognitive functions, including decision-making. By dedicating time to plan and prepare meals, you can incorporate various brain-boosting foods into your diet, enhancing your mental abilities and decision-making skills.
These dietary habits can significantly improve decision-making by enhancing overall brain health and function. The effects of nutritional changes on cognitive functions can vary from person to person, so it’s essential to listen to your body and adjust your diet according to what feels best for you.

👋 Let's talk
I am delighted that you have my article! Your decision to invest in your professional development through learning and mentorship is remarkable — and I am here to ensure that this journey exceeds your expectations.
Here I’m sharing the lessons I learned along the way, and I hope you find my articles helpful in your career journey. Send me a message and let me know.
Since starting my professional career (18+ years ago), I’ve been fortunate to be surrounded by great leaders.
I didn’t even realize those leaders were mentoring me at the time. They pushed me forward (beyond so-called common sense) and shared with me their lessons learned. We didn’t always agree, but their beliefs and consistency led me to trust them and discover myself. I’ve learned some things along the way.
This is a fantastic opportunity for us to grow together.
