Nuts & Seeds: Calories, Healthy Fats & Nutrition Data

Nutritional Value of Nuts and Seeds

Nuts and seeds are among the most nutritionally dense foods available, providing significant amounts of healthy fats, protein, fibre, vitamins, and minerals in small portions. Despite their high calorie content, typically 500 to 700 kcal per 100g, research consistently shows that regular nut consumption is associated with reduced cardiovascular disease risk, better weight management outcomes, and lower rates of type 2 diabetes. The British Heart Foundation confirms that nuts can be included as part of a heart-healthy diet, as the fats they contain are predominantly unsaturated.

Healthy Fats, Protein, and Minerals

The fat in most nuts and seeds is largely unsaturated. Walnuts are one of the few plant foods to provide significant amounts of ALA, a plant-based omega-3 fatty acid. Brazil nuts are exceptionally rich in selenium, with a single nut often meeting the entire daily requirement. Almonds and sesame seeds are good sources of calcium, useful for those who consume limited dairy. Pumpkin seeds provide substantial zinc and magnesium. Flaxseeds and chia seeds are high in both ALA omega-3 and dietary fibre, making them easy additions to porridge, smoothies, or yoghurt. Compare protein content with legumes and pulses for other plant-based sources, or see fats and oils for more on healthy fat choices.

Portion Awareness and Practical Use

Because nuts and seeds are calorie-dense, portion awareness matters for those managing their weight. A standard portion is around 30g, roughly a small handful, providing 150 to 200 kcal depending on the variety. Choosing unsalted, unroasted nuts avoids the added salt and oils found in many commercial products. Nut butters are a convenient way to include nuts in the diet, though many commercial versions contain added salt, sugar, or palm oil; look for products where nuts are the only ingredient. Sprinkling seeds over salads, soups, and breakfast dishes is a straightforward way to boost nutrient intake without significantly increasing meal calories.
