The Complete Guide to Healthy Nuts and Seeds
You’ve probably heard that nuts and seeds are good for you. But which ones are actually the healthiest? How much should you actually eat? And are some of the claims about their health benefits too good to be true?
From almonds to chia seeds, I want to share with you how to make nuts and seeds work for your health goals. Whether you’re looking to boost your energy, support heart health, or simply add more nutrients to your diet, the right nuts and seeds can make a real difference. The key is knowing what to choose and how much to eat.
Why Nuts and Seeds Should Be on Your Shopping List
Nuts and seeds might be small, but they’re packed with nutrients your body craves. These little gems contain healthy fats, protein, fibre, vitamins, and minerals that support everything from brain function to heart health.
Research shows that people who eat nuts regularly tend to have lower rates of heart disease and may even live longer. Seeds offer similar benefits, often with even higher concentrations of certain nutrients.
But here’s the thing: not all nuts and seeds are created equal. Some offer more bang for your buck when it comes to nutrition. Others might be overhyped. Let’s separate fact from fiction.
The beauty of nuts and seeds lies in their versatility. You can snack on them straight from the packet, toss them into salads, blend them into smoothies, or use them as ingredients in your favourite recipes. This flexibility makes it easy to incorporate their nutritional benefits into your daily routine without overhauling your entire diet.
The Top Healthy Nuts Worth Eating
Almonds
Almonds consistently top the list of healthy nuts, and there’s solid science behind their reputation. A 30g serving (about 23 almonds) delivers 6g of protein, 3.5g of fibre, and plenty of vitamin E. They’re also rich in magnesium, which many people don’t get enough of from their regular diet.
Studies suggest almonds may help lower cholesterol and blood sugar levels. They’re also one of the most versatile nuts, perfect for snacking, adding to meals, or making into almond butter. Plus, their satisfying crunch makes them a great replacement for less nutritious snacks.
What sets almonds apart is their ability to keep you feeling full. The combination of protein, healthy fats, and fibre works together to curb hunger pangs, making them an excellent choice for people trying to manage their weight.
Walnuts
Walnuts have earned their reputation as “brain food” thanks to their impressive omega-3 content. They contain more omega-3 fatty acids than any other nut. These healthy fats support brain function and may help reduce inflammation throughout your body.
A handful of walnuts (about 14 halves) provides 4g of protein and 2g of fibre. They also contain antioxidants that may help protect against age-related diseases. Some research suggests that regular walnut consumption might even support memory and cognitive function as we age.
The slightly bitter taste of walnuts pairs beautifully with sweet foods like yoghurt and fruit, making them easy to incorporate into breakfast routines. They also work wonderfully in savoury dishes, adding richness and depth to salads and grain bowls.
Pistachios
Pistachios have a unique advantage in the nut world: their shells naturally help with portion control. Studies show that people eat fewer calories when they have to crack shells compared to eating pre-shelled nuts. The visual reminder of empty shells also helps people realise how much they’ve eaten.
These green nuts are rich in protein, fibre, and potassium. They also contain lutein, an antioxidant that supports eye health. Plus, the act of shelling them slows down your eating, giving your brain time to register fullness.
Pistachios are also one of the lower-calorie nuts, making them a smart choice for people who want to enjoy nuts without worrying too much about overdoing it. Their naturally salty flavour makes them particularly satisfying as an afternoon snack.
Brazil Nuts
Brazil nuts deserve special mention for their exceptional selenium content. Just one or two nuts provide your entire daily selenium requirement. This mineral supports immune function and thyroid health, playing crucial roles in your body’s defence systems.
However, their high selenium content means moderation is key. Too much selenium can actually be harmful, so stick to just 1-2 Brazil nuts per day. Think of them as a nutritional supplement rather than a snack food.
These large, creamy nuts have a rich, almost buttery flavour that makes them feel quite indulgent. They’re perfect for people who want maximum nutritional impact with minimal quantity.
Cashews
Cashews are lower in protein than some other nuts but make up for it with their creamy texture and incredible versatility. They’re rich in copper, which helps your body produce collagen and absorb iron more effectively.
They also contain zinc, which supports immune function and wound healing. Cashews work brilliantly in both sweet and savoury dishes, making them perfect for people who want to add more nuts to their diet gradually without dramatically changing their usual foods.
One of the best things about cashews is how easily they blend into creamy sauces and dressings. Soaked cashews can replace heavy cream in many recipes, providing nutrition while maintaining that rich, satisfying texture we often crave.
The Best Seeds for Maximum Nutrition
Chia Seeds
Don’t let their size fool you. Chia seeds pack an impressive nutritional punch in their tiny package. Just 2 tablespoons provide 4g of protein, 10g of fibre, and plenty of omega-3 fatty acids. That’s more fibre than most people get from an entire meal.
These seeds can absorb up to 10 times their weight in water, forming a gel-like consistency. This unique property makes them incredibly versatile—perfect for puddings, smoothies, or as an egg substitute in baking. The gel-like texture also helps slow digestion, keeping you fuller for longer.
Chia seeds have virtually no taste, which means they won’t change the flavour of your favourite foods. You can sprinkle them on yoghurt, blend them into smoothies, or stir them into porridge without even noticing they’re there.
Flaxseeds
Flaxseeds contain lignans, plant compounds that may help balance hormones and potentially reduce cancer risk. They’re also rich in omega-3s and fibre, making them nutritional multitaskers.
Ground flaxseeds are much easier for your body to absorb than whole ones. Whole flaxseeds often pass through your digestive system unchanged, meaning you miss out on their nutritional benefits. Ground flaxseeds can be added to smoothies, yoghurt, or baked goods for an extra nutritional boost.
These seeds have a mild, slightly nutty flavour that works well in both sweet and savoury applications. They’re particularly good in baked goods, where they add moisture and nutrition without overwhelming other flavours.
Pumpkin Seeds
Pumpkin seeds (also called pepitas) are excellent sources of magnesium, zinc, and iron. They also contain plant compounds that may support prostate and heart health, making them particularly beneficial for men’s health.
These seeds have a satisfying crunch and nutty flavour that works well in both sweet and savoury dishes. You can roast them with spices for a healthy snack, sprinkle them over salads and soups, or add them to homemade granola.
Pumpkin seeds are also naturally rich in tryptophan, an amino acid that may help promote better sleep. This makes them a smart evening snack choice, especially compared to sugary or caffeine-containing alternatives.
Sunflower Seeds
Sunflower seeds are packed with vitamin E, an antioxidant that protects your cells from damage. They also provide magnesium, selenium, and healthy fats. Best of all, they’re usually one of the most affordable seed options.
These budget-friendly seeds make a great snack on their own or can be added to trail mix, granola, or baked goods. Their mild flavour and satisfying crunch make them appealing to most people, including children who might be hesitant about other seeds.
Sunflower seeds are also naturally free from most common allergens, making them a safe choice for people with nut allergies who still want to enjoy the benefits of seeds.
Hemp Seeds
Hemp seeds contain all nine essential amino acids, making them a complete protein source. This is quite rare among plant foods and makes them particularly valuable for vegetarians and vegans.
They also provide omega-3 and omega-6 fatty acids in an ideal ratio for human health. Hemp seeds have a mild, nutty flavour and can be sprinkled on almost anything, yoghurt, salads, smoothie bowls, or eaten straight from the packet.
Common Myths About Nut Nutrition (Busted)
Myth 1: Nuts and Seeds Cause Weight Gain
This is perhaps the biggest misconception about nuts and seeds. Yes, they’re calorie-dense. But research consistently shows that people who eat nuts regularly don’t gain more weight than those who don’t.
The reason? Nuts and seeds are incredibly satisfying. Their combination of protein, healthy fats, and fibre keeps you full for hours, reducing the urge to snack on less nutritious foods. Many people find that adding nuts to their diet actually helps them maintain a healthy weight.
The key is eating appropriate portion sizes. A small handful provides significant nutritional benefits and satisfaction without excessive calories.
Myth 2: Raw is Always Better Than Roasted
While raw nuts and seeds do retain all their nutrients, light roasting doesn’t destroy their health benefits. In fact, roasting can make some nutrients more available to your body and can improve digestibility.
The key is avoiding heavily salted or sugar-coated varieties. Choose nuts and seeds that are dry-roasted or lightly salted if you prefer the taste and texture of roasted options. The important thing is choosing varieties you’ll actually enjoy eating regularly.
Myth 3: All Nut Butters Are Equally Healthy
This depends entirely on what’s been added to the nut butter. Natural nut butters with no added ingredients can be just as nutritious as whole nuts. However, many commercial nut butters contain added sugar, salt, and unhealthy oils that significantly reduce their nutritional value.
When choosing nut butters, look for products with just one ingredient: nuts. These provide the same nutritional benefits as whole nuts, just in a more convenient, spreadable form.
Myth 4: You Must Soak Seeds Before Eating
Some people believe you must soak seeds before eating them to remove “antinutrients.” While soaking can make some nutrients more available, it’s not necessary for most people eating a varied diet.
Chia and flax seeds do benefit from soaking because it makes them easier to digest and helps your body absorb their nutrients. But seeds like pumpkin and sunflower seeds are perfectly nutritious when eaten as they are.
Perfect Portion Sizes: Getting the Balance Right
Understanding proper portion sizes is crucial for maximising the benefits of nuts and seeds without overdoing the calories. Here are the recommended daily servings that provide optimal nutrition:
For Nuts:
- Almonds: 20-25 nuts (30g)
- Walnuts: 14 halves (30g)
- Pistachios: 49 nuts (30g)
- Cashews: 18 nuts (30g)
- Brazil nuts: 1-2 nuts only (due to high selenium content)
For Seeds:
- Chia seeds: 1-2 tablespoons (15-30g)
- Flaxseeds: 1-2 tablespoons ground (15-30g)
- Pumpkin seeds: 2 tablespoons (30g)
- Sunflower seeds: 2 tablespoons (30g)
- Hemp seeds: 2-3 tablespoons (30-45g)
These portions provide around 150-200 calories and offer significant nutritional benefits without going overboard. They’re also perfectly sized to provide that satisfying feeling that helps curb cravings for less healthy snacks.

Shopping Smart: What to Look For
Not all packaged nuts and seeds offer the same nutritional value. Here’s how to choose the best options:
Choose:
- Raw or dry-roasted varieties without added oils
- Products with no added salt or minimal salt content
- Nuts and seeds stored in airtight, opaque containers
- Organic options when your budget allows
Avoid:
- Honey-roasted or sugar-coated varieties
- Heavily salted options that mask natural flavours
- Products stored in clear containers exposed to light
- Nuts and seeds with artificial flavourings or preservatives
Store your nuts and seeds in airtight containers in the refrigerator to maintain their freshness and prevent rancidity. Most will stay good for several months when stored properly, though their nutritional value is highest when they’re fresh.
Frequently Asked Questions About Nut Nutrition
Can I eat nuts and seeds if I’m trying to lose weight?
Absolutely. Despite being calorie-dense, nuts and seeds can actually support weight management. Their combination of protein, healthy fats, and fibre helps you feel satisfied longer, reducing overall calorie intake. Just stick to recommended portion sizes.
Are nuts and seeds safe for children?
Most nuts and seeds are excellent for children over 12 months old, providing essential nutrients for growth and development. However, whole nuts can be a choking hazard for young children. Ground nuts and seeds, or nut/seed butters, are safer options for toddlers.
How do I know if my nuts and seeds have gone bad?
Fresh nuts and seeds should smell pleasant and nutty. If they smell rancid, bitter, or “off,” they’ve likely gone bad and should be discarded. Visual signs include discolouration, mould, or an oily appearance.
Can I get enough protein from nuts and seeds?
While nuts and seeds are good protein sources, they shouldn’t be your only protein source. They work best as part of a varied diet that includes other protein sources like legumes, dairy, eggs, fish, or meat, depending on your dietary preferences.
Do roasted nuts lose their nutritional value?
Light roasting has minimal impact on the nutritional value of nuts. In some cases, it can even make certain nutrients more available. However, avoid nuts roasted in unhealthy oils or with added sugars and excessive salt.
So, should I eat them?
Nuts and seeds offer incredible nutritional value, but the key is making them part of a balanced diet rather than expecting miracles from any single food. The best approach is to start small and build habits gradually.
Try replacing your usual afternoon biscuit with a small handful of almonds. Add chia seeds to your morning smoothie. Sprinkle pumpkin seeds on your lunchtime salad. These small changes add up to significant health benefits over time.
Remember, the best nuts and seeds are the ones you’ll actually eat consistently. Don’t force yourself to eat foods you don’t enjoy. Start with one or two varieties that appeal to you most. As they become a natural part of your routine, you can gradually explore other options.
