From the Guidelines
A nutritionally complete vegetarian meal would be a grain bowl containing quinoa, lentils, roasted vegetables, avocado, and seeds, as this combination provides a balanced profile of macronutrients and micronutrients. This meal is supported by the most recent and highest quality study, which emphasizes the importance of a plant-based diet rich in whole grains, fruits, and vegetables for overall health and well-being 1. The study highlights the benefits of a vegetarian diet, including decreased rates of type 2 diabetes and coronary artery disease, and notes that a well-planned vegetarian diet can provide all the necessary nutrients for good health.
Some key components of a nutritionally complete vegetarian meal include:
- Quinoa, which provides complete protein with all essential amino acids
- Lentils, which add additional protein and iron
- A variety of colorful vegetables, such as sweet potatoes, broccoli, and bell peppers, which provide vitamins A, C, K, and various antioxidants
- Avocado, which adds healthy fats and vitamin E
- Pumpkin and sunflower seeds, which provide zinc, magnesium, and omega-3 fatty acids
It's also important to note that a vegetarian diet can be healthy or unhealthy, depending on food choices, and that a vegan diet may require supplemental vitamin B12 and vitamin D 1. However, with proper planning, a vegetarian diet can provide all the necessary nutrients for good health and reduce the risk of chronic diseases. For optimal nutrition, it's recommended to vary vegetables seasonally and consider adding a small amount of fermented food like kimchi for gut health and probiotics.
