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.
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.
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.
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.
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!

Studies have found that fermented foods directly increase the diversity of the gut microbiome, improve blood sugar control, and lower systemic inflammation.
From yogurt to sauerkraut to kimchi and kefir, almost every culture on earth has fermented foods in its traditional cuisines. Fermentation originated naturally, long before human civilization, when wild yeasts and bacteria accidentally encountered sugars, spontaneously triggering chemical transformations.
Now, fermented foods are re-emerging as research is demonstrating their nutritional pros. They are preserved using an age-old process that not only boosts the food's shelf life and nutritional value, but can give your body a dose of healthy probiotics, which are live microorganisms crucial to healthy digestion, according to Dr. David S. Ludwig, a professor of nutrition at the Harvard School of Public Health.
Fermented foods are packed with probiotics that serve a plethora of purposes. Other benefits include:

Fermented foods are defined as foods or beverages produced through controlled microbial growth and the conversion of food through enzymatic action. These foods are transformed by microbes intentionally, unlike spoiled foods that are altered unintentionally by microbes.
A lot of fermented foods are produced across the globe, including dairy, vegetables, grains, and legumes. Some of the popular ones that are consumed are sourdough bread, kimchi, curd, miso, etc.
When we eat fermented foods, the bacteria survive the digestion and make their way to the small and large intestines, where they secrete beneficial compounds, inhibit intestinal pathogens, and influence the composition of the gut microbiome.
Not all fermented foods contain live microorganisms. Major examples of this are chocolate and coffee.
The flavor profiles of both chocolate and coffee are influenced by fermentation, leading to the creation of that unique and rich flavour loved by everyone.
“A big part of the reason that chocolate or coffee tastes different is because of the way that it’s fermented in that region and the microbes that are present in that region,” said Chris Damman, a microbiome and nutrition expert and gastroenterologist at the digestive health center at the University of Washington Medical Center.
Ideally, one or two servings of fermented food should be eaten daily, and new varieties should be tried to gain the full benefits of consuming different types of polyphenols, probiotics, and their by-products.
Fermented foods like kimchi, pickles, and sauerkraut can be relatively high in sodium, so avoid them when on low-sodium diets or with hypertension. Eating too many fermented foods can create problems for those who have a compromised immune system.
For those who are well, look for ways to incorporate fermented foods in your favorite dishes. Here's how:

In a bid to strengthen food hygiene and safety standards, the Food Safety and Standards Authority of India (FSSAI) has directed Food Business Operators (FBOs) across the country to ensure that only food-grade, corrosion-resistant knives, blades, and cutting equipment are used in food handling and processing operations.
The directive, issued under Schedule 4 of the Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011, also requires FBOs to maintain all cutting equipment in a sound and hygienic condition. In addition, the food regulator has asked State Food Safety Commissioners and Regional Directors to maintain strict vigilance and ensure compliance during inspections.
"Schedule 4 of the aforesaid Regulations requires that equipment, utensils and food-contact surfaces used in food handling, preparation, processing, packaging and storage shall be made of food-grade, non-toxic, corrosion-resistant materials and shall be maintained in a hygienic condition so as to prevent contamination of food," FSSAI said in its advisory.
The regulations further require that such equipment and utensils be adequately cleaned and disinfected at appropriate intervals to prevent food contamination.
According to FSSAI, it has come to the regulator's notice that certain food businesses are using rusted, corroded, chipped, painted, damaged, or otherwise unsuitable knives, blades, and cutting equipment during food handling, preparation, processing, cutting, slicing, and packaging operations.
The food regulator noted that the use of rusted, corroded, chipped, painted, damaged, inadequately cleaned, or non-food-grade cutting tools can result in physical, chemical, and microbiological contamination of food.

Eggs are a great source of protein. At the same time, they are one of the most common foods that cause allergies in children.
A new study conducted in Australia showed that introducing eggs to children before the age of one may reduce the risk of allergy by 17 per cent. The findings were published in the journal JAMA Pediatrics.
Jennifer Koplin, Associate Professor at the Child Health Research Centre at The University of Queensland, said: “Australia has one of the highest rates of food allergy in the world, with one in 10 infants allergic to one or more foods".
To curb the allergy rates, the Australian infant feeding guidelines, issued by the Australasian Society of Clinical Immunology and Allergy in 2016, revolutionized allergy prevention by advising parents to introduce well-cooked egg and smooth peanut butter soon after starting solid foods, generally around six months of age.
The research, led by a team from UQ and the Murdoch Children's Research Institute, examined 7,200 children in two Australian population-based studies to assess whether egg allergy rates had declined since the introduction of the guidelines. The risk of allergy decreased by 17 per cent among babies who started eating eggs early.
“Most parents followed the guidelines, and these results provide reassurance that this advice will help reduce the chance of their child developing an egg allergy,” Dr Koplin said.

According to Associate Professor Rachel Peters of the Murdoch Children's Research Institute, the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.
“The introduction of the 2016 guidelines was a major change from most advice given in the 1990s and early 2000s, which recommended parents delay giving eggs and other allergenic foods until 1–3 years of age if there was a strong family history of allergy,” Dr Peters said.
Other common allergy-causing foods, such as cow's milk, fish, sesame, wheat, and tree nuts, are also recommended to be included in a child's diet before one year of age. Dr Koplin, however, urged for more research into food allergies.

According to the Mayo Clinic, egg allergy symptoms usually start a few minutes to a few hours after eating eggs or foods containing eggs. While egg allergies can occur as early as infancy, most children outgrow their egg allergy by age 16.
Egg allergy symptoms can include:
