Cashews - what are they?

Cashews are Brazil nuts with a unique, delicate flavor, often described as creamy and slightly sweet. They pair beautifully with both savory and savory dishes, making them a versatile culinary ingredient. Historically, cashews originated with the Portuguese, who introduced cashew trees from Brazil to India and Portuguese colonies in Africa, such as Mozambique, in the 16th century. From India, cashews spread throughout Southeast Asia and then to Europe. This nut is not only delicious but also offers numerous health benefits, including a rich vitamin and mineral profile, making it an ideal addition to the diet.

The word "cashew" has Portuguese roots, coming from the words caju or acaju, which were borrowed from the Tupi language, an indigenous people of Brazil. These words translate as "nut that produces itself." This name derives from the cashew's growth habit: the nut is not located inside the fruit, but hangs beneath it. This unique structure makes cashews not only botanically interesting but also popular among consumers for their flavor and nutritional properties.

Cashews are not technically nuts, but rather the seed of a fruit. This interesting product grows on a tree that resembles an apple or bell pepper. Beneath the fruit is a shell, which conceals the valuable cashew seed. Despite its botanical classification, the cashew's flavor and its characteristics associated with growing in a shell make it a close relative of nuts. Cashews are widely used in cooking and are considered a healthy food due to their high nutrient content. The Portuguese played a key role in expanding cashew tree plantations, yet cashews remain among the most expensive nuts on the market. This is due to several factors. Firstly, the process of harvesting and processing cashews is labor-intensive and requires significant labor. Secondly, cashew trees require specific climatic conditions and care, which limits their distribution. Furthermore, the growing demand for cashews as a healthy and nutritious food also affects their price. These factors together explain the high price of cashews and their status as a delicacy.

there are not many places in the world where cashews are grown;
the harvest occurs only once a year;
the tree begins to bear fruit only eight years after planting;
harvesting and processing cashews is long and unsafe work.

The benefits of cashews

Nuts are an important element of the Mediterranean diet, which the World Health Organization recommends for the prevention of various diseases. Although the emphasis was initially on walnuts, since the Mediterranean diet originated in Greece, other types of nuts, such as cashews, can also be beneficial. They have a similar composition and contain many beneficial components, making them an excellent addition to a balanced diet. Including nuts in your daily diet can improve your health and reduce your risk of chronic disease.

According to the USDA, the nutritional value of one serving of raw, unsalted cashews provides a significant amount of beneficial nutrients. Cashews are rich in protein, healthy fats, and vitamins, making them an excellent choice for a healthy diet. They contain vitamin E, magnesium, copper, and zinc, which play important roles in maintaining health. Regular consumption of cashews can help improve cardiovascular health, as well as support energy levels and overall well-being. Including cashews in your diet can be especially beneficial for vegetarians and vegans, as they are an excellent source of plant-based protein.

The calorie content of cashews includes protein, fat, and carbohydrates, which are distributed as follows: 12% are proteins, 21% are carbohydrates, and 67% are fats. These indicators highlight the high energy value of cashews, making them a popular choice for those seeking a nutritious diet.

Cashews have numerous beneficial properties that make them a valuable addition to the diet. This nut is rich in protein, which helps build muscle mass and maintain overall health.

Regular consumption of cashews can help improve brain function, as they contain substances that support cognitive function. Additionally, cashews may help control blood sugar levels, making them beneficial for people with diabetes.

Including cashews in your diet can enrich your nutrition and benefit your body.

Who should avoid eating cashews?

Cashews do not have any strict contraindications, but it is important to understand that the body's reaction may vary. Although this superfood is rich in vitamins and minerals, in some cases it can cause negative consequences. Let's consider how cashews affect health and who should be careful with their consumption.

Cashews should be avoided by those who:

— suffer from nut allergies, as this can cause serious reactions.
— have certain diseases, such as gout, due to the high content of purines.
— follow a strict diet limiting fat intake, since cashews are quite high in calories.
— monitor blood sugar levels, since nuts contain carbohydrates.
— has digestive problems, as nuts can cause discomfort.

When choosing alternatives, it is important to consider individual needs and health.

Takes blood-thinning medications. Cashews are rich in vitamin K, which, in addition to strengthening bones, increases blood clotting. This means that the product may reduce the effectiveness of drugs that suppress the activity of the blood clotting system [22].
Prone to allergies. Nuts are one of the most allergenic foods. If a child or adult develops a rash after eating a handful of hazelnuts, the same reaction may occur in response to cashews [23].
Exceeds the calorie intake. If you eat a lot of cashews without limiting yourself in other high-calorie foods, you can gain weight. And quite quickly.

Cashews may increase the risk of kidney stones, although this is rare. Like many plant foods, cashews contain oxalates, which can contribute to the formation of stones in the urinary tract. Although cashews contain a relatively small amount of oxalates, their absorption in the intestines is more active due to the high fat content. Researchers Margarita Bernardino and Malvinder Parmar from the University of Ontario (Canada) emphasize that the risk of urolithiasis increases when the recommended daily intake of cashews is exceeded. Therefore, it is important to control the amount of nuts in the diet to minimize possible health risks.

Is it true that cashews contain toxins?
Cashews should not be eaten raw because they contain the toxic substance urushiol, which is present in unshelled, unprocessed nuts. Urushiol can cause skin irritation, rashes, and even burns if ingested or comes into contact with the skin. To remove these potentially harmful components, cashews are roasted or steamed. Even nuts labeled as "raw" are not actually raw, as they have not been roasted and do not contain salt. However, they have been heat-treated and free of toxins, making them safe for consumption.
Raw nuts, unlike processed ones, are easily distinguished by color. Raw cashews have a green tint, while steaming them turns them light beige or cream. Steaming not only changes the appearance of the nuts but also makes them safe to eat.

Can I eat cashews every day?

To preserve all their beneficial properties, it is recommended not to roast cashews; instead, eat them raw or lightly roasted without oil. Cashews can also be added to a variety of dishes, such as salads, smoothies, and desserts. Portion control is important, as this nut is quite high in calories. Eating cashews properly can help improve metabolism and maintain energy throughout the day.

Choose cashews without salt, oil, or other additives.
Give nuts the right place in your diet—eat them instead of snacking on chips or popcorn, and not with other high-calorie foods.
Limit yourself to one serving per day—that's 28-30 grams, or about 18 nuts, or a handful. That's how much you can fit in the palm of your hand. Children should be given as many nuts as they can fit in the palm of their hand. Typically, this is no more than five nuts [25].

Cashews are recommended to be stored in an airtight bag placed in a cool, dark, and dry place, such as the freezer. When stored this way, the nuts will retain their nutritional value even for up to a year. However, it is worth noting that tasty cashews usually expire much faster and do not last long. Proper storage of nuts helps preserve their freshness and nutritional value, making them an excellent choice for a healthy diet.
