Cashews have long enjoyed a spot among the esteemed members of the nut family, gracing snack bowls, trail mixes, and gourmet recipes alike. With their creamy texture, delightful crunch, and rich nutritional profile, they’re a staple in many households and cuisines worldwide. But what if we told you that cashews, the humble kitchen favorite, aren’t actually nuts?

Much like peanuts, which are scientifically classified as legumes, cashews belong to a completely different botanical category. Surprising, right? This article delves deep into the botanical intricacies and culinary mysteries surrounding cashews, offering a clearer understanding of where this beloved ingredient truly belongs.

What Is a Nut?

To unravel the mystery of cashews, it’s essential to first understand what defines a "true" nut. Botanically, a nut is a dry fruit encased within a hard shell, containing a single seed. The hard shell doesn’t split open when the fruit ripens, distinguishing nuts from other plant-based foods. Examples of true nuts include acorns, chestnuts, and hazelnuts. These are the quintessential representatives of the nut family.

In contrast, many foods colloquially referred to as nuts—like cashews, almonds, and pistachios—do not fit this scientific definition. So, if cashews aren’t nuts, what are they?

Cashews are classified as drupes. Drupes are fruits that have a fleshy exterior surrounding a single seed encased in a hard shell. The part we consume—the cashew “nut”—is the seed of this drupe.

The cashew tree, scientifically known as Anacardium occidentale, produces a fascinating fruit structure. The visible pear-shaped cashew apple, which often draws attention, is not the actual fruit. Beneath it hangs a small, kidney-shaped drupe. Inside this drupe lies the cashew seed, which is what we eat.

Interestingly, the cashew’s outer shell is inedible due to the presence of urushiol, a toxic compound also found in poison ivy. This makes the processing of cashews labor-intensive, as the shells must be carefully removed to ensure safety.

Not a Legume Either

Given their culinary similarity to peanuts, you might wonder if cashews are legumes. However, legumes grow in pods containing multiple seeds that split open when mature. Examples include beans, peas, and peanuts.

Although cashews, like peanuts, can be split in half, their development within a drupe rather than a pod excludes them from the legume family. Cashews occupy a unique botanical category, making them difficult to classify strictly.

Culinary Classification vs. Botanical Classification

While cashews may not be nuts by botanical standards, they’re treated as nuts in the culinary world. Why? Because cashews share many characteristics with true nuts:

Nutritional Profile: Like nuts, cashews are rich in healthy fats, protein, and essential nutrients, making them a key ingredient in energy-boosting snacks and recipes.

Culinary Uses: Cashews are versatile and can be used in everything from nut butters and trail mixes to stir-fries and desserts, much like almonds or walnuts.

Interestingly, many popular “nuts” aren’t botanically nuts either. Walnuts, pecans, pistachios, and almonds are also drupe seeds. Even with their misclassification, cashews’ nutritional and culinary contributions have cemented their place in the nut aisle.

Nutritional Benefits of Cashews

Regardless of classification, cashews are undeniably nutritious. They are packed with essential nutrients like magnesium, zinc, iron, and vitamins B6 and K. Their high content of monounsaturated fats supports heart health, while their protein and carbohydrate content make them a satisfying snack for sustained energy.

Cashews are also an excellent plant-based source of copper, which plays a vital role in energy production, brain health, and immune function. Adding them to your diet can offer numerous health benefits, whether sprinkled over salads, blended into creamy sauces, or enjoyed as a simple roasted snack.

Understanding the botanical classification of cashews not only satisfies curiosity but also highlights the incredible diversity of plant-based foods. It’s a reminder of the complexity of the natural world and the importance of accurate labeling in agriculture and nutrition.

Moreover, cashews’ unique classification showcases their versatility. Whether you consider them nuts, drupes, or seeds, there’s no denying their culinary and health value. Their rich flavor, satisfying texture, and nutrient-dense profile make them a standout ingredient across cuisines and diets.

So, are cashews nuts? Botanically, no. Cashews are drupe seeds, with a fascinating journey from tree to table. Yet, in the culinary world, they’ve earned a spot alongside true nuts, thanks to their similar flavor, texture, and nutritional attributes.

Regardless of their classification, cashews are a delicious, versatile, and nutritious food. Whether you’re enjoying a handful as a snack, blending them into a creamy vegan sauce, or incorporating them into a dessert, cashews deserve a place in your pantry and your diet.

Next time you reach for a bowl of “mixed nuts,” remember the botanical intricacies that make each ingredient unique- and give a little extra appreciation to the not-so-nutty cashew!

One extra serving of leafy greens like kale and spinach may be good for your lungs and help you breathe better, according to a study. The secret? It is the vitamin K1 found in leafy green vegetables.

Researchers from Edith Cowan University (ECU) tracked more than 179,000 adults over a decade and found that people who eat more vitamin K1-rich foods such as leafy green vegetables may lower their risk of chronic lung disease and boost lung function.

“We found that people who ate more vitamin K1-rich green vegetables had better lung function and were less likely to develop COPD,” ECU researcher Chengfeng Li said.

“Just one extra serve of leafy greens like kale, about one and a half to two cups a day, is an achievable way to boost your vitamin K1 intake,” Li added.

What Are The Key Findings

The findings suggest that adding more greens to your plate could help keep your lungs in better shape as you age.

The study found that those with the highest intake of vitamin K1 had about a 16 per cent lower risk of COPD compared to those eating the least.

They also had better lung performance, meaning their lungs could hold and move more air, a key sign of good respiratory health.

“Vitamin K likely activates a protein that protects the lungs’ elastic fibers - the tiny structures that let your lungs expand and contract,” Associate Professor Marc Sim said.

“When these fibers break down, breathing becomes harder over time. This nutrient may help keep lung tissue flexible and prevent damage,” Sim added.

The second type, vitamin K2, showed no benefit for COPD risk, though it was linked to somewhat better lung function at moderate intakes.

The researchers think the same protective mechanism probably applies to vitamin K2, but any benefit may be masked by what it's eaten alongside.

K1-rich leafy greens, by contrast, come with their own bonus nutrients like fiber and antioxidants that may boost the effect, while K2's main sources, including processed and red meat, are linked to poorer health outcomes.

The study also found no link between vitamin K and asthma, suggesting vitamin K may be more relevant for long-term lung damage rather than allergic conditions.

Smoking May Dent Benefits

While the boost from greens appears favorable, researchers are clear on one thing: it won’t cancel out smoking.

“The biggest thing you can do for your lungs is to quit smoking and reduce your exposure to environmental pollution,” Li said.

“But a healthy diet may still play a supporting role by counteracting some of the damage caused by these harmful factors.”

“Eating more leafy greens is a simple step that could help support lung health over time.”

How To Keep Your Lungs Healthy?

The World Health Organization data shows that chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death worldwide. The condition was responsible for an estimated 3.5 million deaths in 2021, according to the latest available global data.

COPD is a common and serious lung disease, and the WHO noted that smoking, indoor and outdoor pollution, and harmful inhalants are among its most significant triggers.

If your breathing feels effortless, steady, and natural, so much so that you barely notice it, your lungs are likely in good shape. To maintain this good lung health, it is essential to:

• maintain a balanced weight,
• eating nutritious food,
• exercise regularly,
• avoiding tobacco,
• avoiding vaping,
• keep away from inhaled irritants.

For years, weight loss advice has been dominated by a single message: eat less. From crash diets to extreme calorie counting, the assumption has been that consuming fewer calories is the ultimate solution to obesity. While reducing excessive calorie intake can contribute to weight loss, the reality is far more complex. Sustainable weight management requires understanding the science of metabolism, behaviour, hormones, sleep, stress, and long-term lifestyle patterns rather than relying solely on restriction.

Why Restrictive Diets Don't Help

The human body is not a simple mathematical equation. It is an adaptive system designed to protect itself. When calorie intake is drastically reduced, the body often interprets this as a potential threat and responds by slowing metabolism to conserve energy. Hunger hormones such as ghrelin increase, while hormones responsible for satiety decrease. As a result, people often feel hungrier, more fatigued, and less motivated over time.

This explains why many restrictive diets may show short-term success but fail to deliver sustainable outcomes. Initial weight loss is often followed by plateaus or weight regain, leaving individuals frustrated and blaming themselves for lacking discipline. In reality, biology plays a significant role in resisting prolonged calorie deprivation.

Food Quality and Lifestyle Factors

Equally important is the quality of food being consumed. Two meals with the same calorie count can affect the body very differently. Diets rich in processed foods, refined sugars, and unhealthy fats can lead to rapid blood sugar fluctuations, increased cravings, and poor satiety. On the other hand, balanced meals containing adequate protein, fibre, healthy fats, and micronutrients help regulate appetite and support metabolic health.

Lifestyle factors also play a critical role in sustainable weight management. Chronic stress elevates cortisol levels, which may contribute to increased fat storage and emotional eating. Poor sleep disrupts hormones that regulate hunger and fullness, often increasing cravings for high-calorie foods while reducing energy levels for physical activity. Sedentary lifestyles further compound the issue.

Weight loss is also deeply connected to behavioral and emotional health. Many eating habits are influenced by stress, social environments, routines, and emotional triggers rather than true hunger. Advising someone to “just eat less” overlooks these underlying drivers. Without addressing behavioral patterns, sustainable change becomes difficult.

This evolving understanding of obesity has shifted the conversation from blame and willpower to science and personalized care. Today, obesity is increasingly recognized as a chronic, multifactorial condition that requires comprehensive management strategies tailored to individual needs.

Lifestyle modifications such as balanced nutrition, regular physical activity, sleep optimization, and behavioral counselling remain the cornerstone of treatment. However, for some individuals, especially those struggling with obesity-related health concerns or repeated cycles of weight regain, lifestyle interventions alone may not always be sufficient.

Endoscopic Procedures

In recent years, minimally invasive endoscopic procedures have emerged as additional tools within medically supervised weight management programs. Procedures such as endoscopic sleeve gastroplasty (ESG) help reduce stomach volume to promote early satiety, while intragastric balloons can aid portion control and behavioral modification. Transoral outlet reduction (TORe) may also help individuals experiencing weight regain after bariatric surgery.

These procedures are not shortcuts or substitutes for healthy habits. Instead, they work in conjunction with long-term dietary and lifestyle interventions to support sustainable outcomes in appropriately selected patients.

Sustainable Weight Loss

Ultimately, sustainable weight loss is not about punishing the body through extreme restriction. It is about understanding how the body functions, identifying the biological and behavioral factors influencing weight, and creating realistic, long-term strategies that support overall health.

The future of weight management lies not in simplistic advice, but in compassionate, science-backed, and personalized care. Only by moving beyond the outdated “eat less” narrative can we create healthier and more sustainable approaches to obesity management.

India's food regulator, FSSAI, has issued notices to six beverage brands, including Red Bull and PepsiCo India, for claiming to be "energy drinks," citing misbranding and misleading claims.

The brands include:

• Red Bull Energy Drink
• PepsiCo – Adrenaline Rush Energy Drink
• Reliance Consumer Products – Campa Energy Gold Boost
• Sting Energy Drink
• Hell Energy
• Coca-Cola-backed Monster

Why FSSAI Issued Notices

The FSSAI, in a post on social media platform X, noted that it has not notified any standard for "energy drink" or similar products.

The regulator stated that these brands have "marketed using descriptors such as 'energy drink' on product branding and labelling."

The FSSAI further said that the Food Category System under the FSS Regulations is not intended for product naming or labelling purposes.

"Functional or therapeutic claims, including but not limited to 'vitalizes body and mind', 'enhancing focus', 'boost energy levels', 'aid in general weakness', or similar conditions, are not permissible for food products under the FSS Act 2006 and the Rules and Regulations made thereunder," the regulator said.

Recently, Maharashtra State FDA Minister Narhari Zirwal told the Assembly that the state is set to ban the sale of Sting energy drink within 500 meters of schools.

Are Energy Drinks Healthy?

Energy drinks have become a fad among the youth population and are linked to rising fitness awareness. According to the IMARC Group, India's energy drinks market was valued at $1.5 billion in 2025 and is projected to reach $2.9 billion by 2034.

However, Dr. Sudhir Kumar, neurologist at Apollo Hospitals, Hyderabad, said energy drinks may not actually provide "energy."

Rather, they are loaded with "caffeine, sugar and stimulants" that may not be healthy and are "not necessary for exercise, gym workouts or sports."

"Some studies suggest caffeine can improve alertness and endurance in certain athletes. But that doesn't mean everyone who goes to the gym or for a morning run needs an energy drink. Most recreational exercisers do not need energy drinks," said the noted neurologist known popularly as Hyderabad doctor.

He noted that for people working out for less than an hour: "Water is usually enough".

"If you need extra fuel, ordinary carbohydrate-rich foods, such as a banana, fruit, dates or a simple meal, are often safer and cheaper than an energy drink".

Dr Sudhir also noted the downsides of energy drinks many of which contain large amounts of added sugar, high doses of caffeine and multiple stimulants whose combined effects are not always well studied.

He liked excess intake of energy drinks with:

• Weight gain
• Obesity
• Type 2 diabetes (especially sugar-sweetened drinks)
• High blood pressure
• Sleep disturbance
• Anxiety and palpitations
• Dangerous heart rhythm problems."

Over the past few years, there has been a significant increase in young patients presenting with liver dysfunction. Energy drinks may be one of the culprit, according to Dr. Abhideep Chaudhary, President of the Liver Transplantation Society of India (LTSI) and Chairman and Head, Department of HPB and Liver Transplantation, BLK-Max Hospital, New Delhi.

"Three major contributors stand out — energy drinks, alcohol, and high-sugar beverages. Energy drinks, often perceived as harmless, contain high levels of caffeine, sugar, and chemical additives that place immense stress on the liver," the doctor said.

Who Should Avoid Energy Drinks?

Dr. Sudhir suggested people should avoid or strictly limit energy drinks if they are:

• Children and adolescents
• Pregnant or breastfeeding women
• People with heart disease
• People with hypertension
• People with anxiety disorders
• People with sleep problems.
