Research continues to shed light on the health benefits of nuts and seeds. Flaxseeds, chia seeds, and sunflower seeds are well-known options, but there are several lesser-known varieties of readily available seeds with potential health effects.
General Characteristics of Seeds
Seeds contain the embryo of future plants. To support their development from embryo to plant, seeds are endowed with ample energy and nutrients. This efficient packaging makes seeds calorie dense, so it is important to be aware of appropriate portion sizes when eating seeds as a snack or ingredient. Unique nutrition profiles exist for different seed varieties, therefore, including a diverse array of seeds in your diet can promote health. Seeds are typically a source of protein, unsaturated fats, minerals, and phytonutrients. For individuals with nut allergies, seeds and seed butters offer excellent substitutes!
Consider trying one or all of these tasty and nutritious superstar seeds:
Sesame seeds are a good source of fiber, which not only supports digestive health but may play a role in reducing risk of obesity, type 2 diabetes, certain cancers, and heart disease. Some studies indicate that regular consumption of sesame seeds may help reduce cholesterol and triglycerides. Sesame seeds also provide phytonutrients (lignans and phytosterols) that may have cholesterol-lowering effects. These tiny seeds supply 5 grams of protein per 3-Tbsp serving and the micronutrients B-vitamins, iron, zinc and copper. Unhulled sesame seeds are especially rich in calcium, a nutrient vital to bone health. Try adding sesame seeds to cereal, stir-fries or steamed veggies, smoothies, or salad dressings.

Pumpkin seeds contain a range of beneficial nutrients, including sterols, magnesium, and polyunsaturated fatty acids. Research indicates that the nutrients in pumpkin seeds may protect against type 2 diabetes and heart disease as well as promote bone health. Pumpkin seeds are a rich source of the amino acid tryptophan, which the body converts into serotonin, a neurotransmitter that promotes relaxation. Pumpkin seeds are a great snack and add crunch and taste to recipes. Top a salad with pumpkin seeds or make homemade pumpkin seed butter by blending whole, raw pumpkin seeds in a food processor.
Tomato seeds may be more difficult to digest than most seeds, but they are worth the trouble since they provide a healthy dose of vitamins A and C, potassium and fiber. The seeds also contain lycopene, a phytonutrient known to reduce cancer risk; cooking helps activate lycopene in tomato seeds. The seeds are often consumed dried, but can be enjoyed in tomato sauces or as part of whole tomatoes.
