From the Guidelines
A nutritionally complete vegetarian meal that meets your requirements would be a Greek yogurt parfait with mixed berries, nuts, seeds, and honey, as it provides complete protein, healthy fats, fiber, and numerous micronutrients without requiring cooking beyond microwaving frozen berries if desired. This meal is supported by the most recent and highest quality study, which suggests that a Mediterranean diet, rich in fruits, vegetables, whole grains, and nuts, may have potential preventive benefits against cognitive impairment 1. The omega-3 fatty acids from seeds and nuts, such as chia seeds, ground flaxseeds, and walnuts, have been shown to reduce inflammation and support brain health, potentially improving anxiety and cognitive function 1. The probiotics in yogurt support gut health, which is increasingly linked to mental wellbeing through the gut-brain axis.
Some key benefits of this meal include:
- High protein content from Greek yogurt to support muscle health and satisfaction
- Antioxidants and vitamins from mixed berries to support overall health and wellbeing
- Omega-3 fatty acids from seeds and nuts to support brain health and reduce anxiety
- Probiotics from yogurt to support gut health and mental wellbeing
- Customizable with additional nutrients such as microwave-steamed sweet potato or plant-based protein powder
It is essential to note that while the evidence is not yet conclusive, following a Mediterranean diet, as suggested by the most recent study 1, may have potential benefits for cognitive function and mental health. Therefore, incorporating this meal into a balanced diet, along with other nutrient-dense foods, may help support overall health and wellbeing.

- Legumes, such as lentils or chickpeas, which are rich in protein, fiber, and essential minerals
- Nuts and seeds, such as walnuts or chia seeds, which are rich in omega-3 fatty acids and antioxidants
Preparation Methods
To prepare a vegetarian meal with minimal risk of illness, it is essential to follow proper food safety guidelines. Some tips include:
- Using a microwave to heat food to an internal temperature of at least 165°F (74°C)
- Using a food thermometer to ensure that food is cooked to a safe temperature
- Avoiding cross-contamination with raw or undercooked foods
