What Makes Food Nutritious?
Nutritious foods are those packed with essential vitamins, minerals, fiber, protein, and healthy fats, offering significant health benefits compared to calorie-dense, low-nutrient options. Including these nutrient powerhouses in your diet is fundamental for overall health.
1. Salmon: The Omega-3 Powerhouse
Salmon is a fatty fish celebrated for its high-quality protein and abundance of omega-3 fatty acids like EPA and DHA, vital for heart and brain health. It also supplies selenium, vitamin D, and B vitamins. Omega-3s support cognitive function, potentially reducing cognitive decline, and contribute to cardiovascular health by helping lower blood pressure and triglycerides.
2. Quinoa: The Complete Plant-Based Protein
Quinoa, a complete protein source with all nine essential amino acids, is an excellent plant-based option. It's high in dietary fiber, aiding digestion and weight management. Quinoa is also rich in antioxidants and provides essential minerals like manganese, magnesium, and phosphorus.
3. Leafy Greens: Vitamins Galore
Leafy greens such as spinach and kale are nutrient-dense, offering a wealth of vitamins, minerals, and antioxidants. They support eye and skin health with vitamins A and C, and antioxidants like lutein and zeaxanthin. Their blend of vitamins A, C, K, and minerals like iron boosts immunity and promotes strong bones through Vitamin K and calcium.
4. Berries: The Antioxidant Army
Berries are rich in antioxidants, particularly anthocyanins. Consuming berries regularly can benefit heart and brain health due to their anti-inflammatory properties, help regulate blood sugar levels, and support healthy digestion with their high fiber content.
5. Nuts and Seeds: Healthy Fats and Fiber
Nuts and seeds like almonds and chia seeds provide healthy fats, fiber, protein, and minerals. Their healthy fats and antioxidants can improve cardiovascular health by lowering 'bad' cholesterol. Despite being calorie-dense, their protein and fiber content aid in weight management by increasing satiety. They also offer important minerals like magnesium, zinc, and selenium.
