For many of us, walnuts\u00a0evoke images of neglected mixed nuts bowls at\u00a0Christmas<\/a>\u00a0– the last resort after you\u2019ve exhausted all the more exciting, but not-so-nutritious, snacks.<\/p>\n

They\u2019re not the cheapest, nor the trendiest and certainly not the easiest to snack on mindlessly.\u00a0<\/p>\n

So why factor them into your diet? Well, say experts, nutritionally, these brain-shaped nuts punch well above their weight.<\/p>\n

Walnuts are packed with a type of healthy fat that much of the UK is considered deficient in.\u00a0<\/p>\n

Called omega-3 fatty acids, these compounds are essential for our heart, brain and eye health – helping to lower blood pressure, prevent blood clots and manage depression<\/a> and anxiety.\u00a0<\/p>\n

And unlike other nuts, walnuts are particularly rich in one type of fatty acid – called alpha-linolenic acid (ALA) – which is more commonly associated with oily fish.<\/p>\n

ALA is crucial for keeping cells in the body healthy – and has been shown to play a key role in managing blood sugar and treating nerve damage.\u00a0<\/p>\n

And that’s not to mention walnuts’ effect on cholesterol. A growing body of research walnuts can significantly lower ‘bad’ LDL cholesterol.\u00a0<\/p>\n

\"For <\/div>\n<\/p><\/div>\n

For many of us, walnuts evoke images of neglected mixed nuts bowls at Christmas – the last resort after you\u2019ve exhausted all the more exciting, but not-so-nutritious, snacks<\/p>\n<\/div>\n

In fact, studies suggest that just one handful of walnuts a day is enough to lower total cholesterol by nearly seven per cent.\u00a0<\/p>\n

So, how can you harness the health benefits of walnuts? We asked top nutritionists your burning questions…<\/p>\n

Aren’t nuts really high in fat? What makes them healthy?<\/span><\/h2>\n

Walnuts are little powerhouses when it comes to nutritional value.\u00a0<\/p>\n

One 28g serving contains roughly 180\u2013200 kcal, which is about seven to 10 per cent of the NHS’s daily calorie guideline (2,000 for women, 2,500 for men).<\/p>\n

They are high in fat – with around 18g per serving – making a significant contribution towards the 20g recommended for women and 30g for men.\u00a0\u00a0<\/p>\n

But nutritionists say that most of this is actually unsaturated \u201chealthy\u201d fat – full of omega-3.<\/p>\n

You also get around 2g of fibre per serving, helping towards the 30g daily recommendation, while the carbohydrate and sugar content is low.<\/p>\n

Nutrients-wise, they\u2019re rich in vitamin E, magnesium and polyphenols, which act as antioxidants to reduce oxidative stress and inflammation.\u00a0<\/p>\n

Polyphenols are often linked to reduced inflammation and lower long-term risk of conditions like heart disease.<\/p>\n

In fact, munching on handfuls of walnuts every day has been linked to improved heart health, better cholesterol levels and reduced inflammation.<\/p>\n

Be aware though, they\u2019re calorie-dense, so eating more of them isn\u2019t always better.\u00a0<\/p>\n

What does the research say about the health benefits of walnuts?\u00a0<\/span><\/span><\/h2>\n

The omega-3 fats and polyphenols contained in walnuts have both been linked to brain health.<\/p>\n

Some studies suggest the nuts may support cognitive function and be helpful in reducing age-related decline.\u00a0<\/p>\n

Their antioxidant content may also help protect brain cells from damage. As with many scientific studies, the evidence is promising but, so far, not definitive.<\/p>\n

It’s heart health where walnuts really come into their own, however.\u00a0<\/p>\n

A major study, published in Circulation found walnut consumption reduced total and LDL ‘bad’ cholesterol.\u00a0<\/p>\n

Another large trial, the WAHA study (Walnuts and Healthy Aging), showed regular intake improved lipid profiles in older adults.<\/p>\n

And an analysis in The American Journal of Clinical Nutrition confirmed consistent cholesterol-lowering effects across multiple trials.<\/p>\n

But what makes walnuts better than other nuts?\u00a0<\/span><\/h2>\n
\n

\"Nutrients-wise, <\/div>\n<\/p><\/div>\n

Nutrients-wise, walnuts are rich in vitamin E, magnesium and polyphenols, which act as antioxidants to reduce oxidative stress and inflammation<\/p>\n<\/div>\n

There is not a single nut in the world that can match walnuts for their omega-3 content.<\/p>\n

In fact, they are the only commonly eaten nut high in alpha-linolenic acid (ALA), which is a plant-based omega-3 fat.<\/p>\n

While walnut ALA isn\u2019t as potent as the omega-3s found in fish, it is still very helpful for the body.<\/p>\n

And if you don\u2019t like fish, or you don\u2019t eat meat, walnuts are one of the best alternatives for omega-3.<\/p>\n

\u2018Omega-3 is an essential fatty acid, meaning we must obtain this through our diet, as we cannot make it ourselves,\u2019 says registered nutritionist Jen Walpole<\/a>.<\/p>\n

\u2018Omega 3 is extremely anti-inflammatory, supportive of cardiovascular function, brain function, hormonal health and fertility.\u2019<\/p>\n

Can eating walnuts help with weight loss or appetite control?<\/span><\/h2>\n

With a perfect combination of fibre, fat and protein, walnuts are great for snacking, say experts, especially when you\u2019re implementing appetite control measures.<\/p>\n

You\u2019ll feel fuller for longer after eating them, which may help reduce cravings and overall calorie consumption.\u00a0<\/p>\n

Keep a bag on your desk at work, or in your pocket when you\u2019re on the move to stave off any hunger pangs, says Ms Walpole. Just be aware of overconsumption.<\/p>\n

\u2018Omega-3 intake is positively associated with weight loss, perhaps owing to the fact healthy fats are satiating, help with blood glucose control and impact cravings, too,\u2019 she explained.<\/p>\n

\u2018A little goes a long way too – being rich in fat, fibre and protein helps make them incredibly satisfying and satiating.\u2019<\/p>\n

Are there any side effects of eating too many walnuts?<\/span><\/h2>\n

Walnuts are a common allergen, so be cautious if you haven\u2019t eaten them before – or at least not on a regular basis.<\/p>\n

Overeating walnuts is a big no no.\u00a0<\/p>\n

They can impact calorie count due to their high fat content. Of course, having too many will also influence weight management goals.<\/p>\n

Some people may also experience digestive discomfort if consuming large amounts.\u00a0<\/p>\n

Overall, says Ms Walpole, keep your consumption within the daily recommendation and you\u2019ll get everything you need.<\/p>\n

Likewise, it’s worth being aware of walnuts’ interaction with various medications.\u00a0\u00a0<\/p>\n

Those on blood-thinning drugs should seek advice from a medical practitioner before embarking on any kind of walnut-heavy diet regime, says Ms Walpole.\u00a0<\/p>\n

What should you pair them with for maximum nutrition?<\/span><\/h2>\n

Walnuts are a very easy upgrade to many meals, and they\u2019re often used in baked recipes to add crunch – like banana bread, for instance.\u00a0<\/p>\n

Crushed and sprinkled on salads, or mixed in with whole grains, will create a harmonious pairing, especially with leafy greens that are packed with vitamin C.<\/p>\n

Elsewhere, adding them to fibre-rich meals helps you move closer to your 30g daily fibre target, while chucking them in with key protein sources – lean meat, for instance – can improve satiety.<\/p>\n

\u2018Walnuts are a great addition to any salad or vegetable dish (think toasted walnuts) and even work well as a snack alongside some berries as a fibre-rich snack or yoghurt for a protein focus,\u2019 says Ms Walpole.<\/p>\n

\u2018Walnuts also pair well with dark chocolate and may help to reduce sugar cravings or overeating chocolate. They would also be a great addition to a bowl of porridge oats for a well-balanced breakfast.<\/p>\n

\u2018By adding walnuts and increasing the fat\/protein content of this meal, it will help stabilise blood sugars and keep you fuller for longer.\u2019<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
