The best nuts
Macadamia nuts
The Macadamia nut is the fruit of the Macadamia tree of Australian origin. Today the main production is located in the Hawaiian Islands, but also in Brazil and California, where trees from Australia were imported during the late 19th century.
[Macadamia nuts] have a low carbohydrate content and a high percentage of fat making them excellent for the ketogenic diet .
These nuts also have a high amount of minerals and antioxidants. In fact, they are rich in flavonoids, antioxidants that are excellent for purifying the toxins to which we are exposed daily.

Pecan nuts
Pecan nuts are the fruit of pecan, a tree native to North America, but are also present in southern Italy in some plots.
These nuts have a high fat content and a low carbohydrate content, therefore they are perfect as a snack, but having a concentration of calories among the highest in the category, a moderate consumption is recommended.
Like many nuts it contains vitamins and minerals such as magnesium, potassium, phosphorus, vitamin E and vitamin B1 (thiamine) just to name a few.
Pecan nuts also contain oleic acids which help to control cholesterol levels, as well as prevent diseases of the circulatory system and various types of cancers.
So these nuts are good for the heart, muscles and nervous system.
Pili nuts
Pili nuts are native to Southeast Asia, Papua New Guinea, and North Australia, but are grown predominantly in the Philippines.
These nuts are best for those on the ketogenic diet, having the highest fat content and lowest carbohydrate content of all nuts.
Being grown in volcanic environments, they have a high content of minerals and nutrients such as vitamin E, magnesium, potassium, calcium and phosphorus.
They are rich in anti-oxidants and promote the health of the circulatory system and therefore help maintain a healthy heart.
They help fight insomnia thanks to the essential minerals they are rich in, in particular magnesium.
Brazil nuts
Brazil nuts are nuts of Amazonian origin and are the fruit of the Bertholletia excelsa tree. They are native to Brazil, but also grow in Peru and Amazonian Bolivia.
These nuts have a high content of healthy fats and are also among the most caloric nuts of all, so it is advisable to consume them in moderation.
They are an abundant source of selenium, an essential mineral for purifying the body from free radicals and heavy metals such as mercury. In addition, selenium helps support the thyroid by helping to convert the hormone T4 (inactive form) into T3 (active form).
Walnuts
The Walnut it is the fruit of the tree of the Junglas genus. The two most common species are Juglans regia of Persian origins and Juglans nigra of North American origins. China is the largest producer of walnuts, but the world's largest exporters are the United States and Turkey.
Several studies have proven that walnuts are fantastic for brain health, especially in Alzheimer's patients an improvement in cognitive function was noted compared to the control group.
Studies have also shown how they can help prevent certain types of cancers such as colon, prostate and breast cancers.
As a last point, walnuts help support a healthy gut, which is the starting point for overall health.
Nuts to be consumed in moderation
Pistachios
Pistachio is the fruit of the tree of the Pistacia genus, which belongs to the Anacardiaceae family. Pistachio has Middle Eastern origins and Iran is considered the world's largest exporter.
Pistachios have slightly more carbohydrates than almonds, hazelnuts, walnuts, etc.
However, they can be consumed in moderation, and being usually sold still in the shell and since it takes longer to peel them, it is also easier to eat a few at a time.
Almonds
Almonds they are a good source of minerals and are probably the most common and consumed nuts.
They became popular on the ketogenic diet because almond flour is substituted for common flour in many recipes, especially sweets, desserts and bread, and this makes excessive consumption very easy.
In moderation they shouldn't cause problems, but it's good to be aware of the amount of almonds present in these ketogenic recipes.
In fact Almonds contain phytic acid which is considered an anti-nutrient. This means that it has a contrasting effect on nutrition by reducing the absorption of nutrients and the greater the amount we take in, the lower the amount of minerals that the body will be able to absorb.
Nuts to avoid
Cashews
Cashews come from tropical trees in the Anacardiaceae family. They are currently produced in the equatorial areas of Central America.
Cashews are the only nuts I recommend avoiding as they have the highest concentration of carbohydrates and can create digestive problems. In fact, the shell contains urusciolo, an oil with toxic and allergic properties. Furthermore, the cashew nut is technically not a nut fruit, but the seed of the cashew fruit.
Although the flavor of cashews is very good and the fruit contains many minerals there are several nuts with better nutritional values that are preferable to consume.
Peanuts
Peanuts are the fruits of the peanut, a plant of South American origin. They are mostly produced in Africa and Asia, but there are also plots in Europe, in particular Greece, Spain and Italy.
It is advisable to avoid this type of walnut because of the allergic reactions it could create, but above all because it could contain aflatoxins, or mycotoxins produced by some types of fungi and which are among the most carcinogenic substances in existence.
Conclusion
Nuts are a great snack, source of vitamins and minerals and healthy fats. There are several types of nuts with excellent nutritional properties, such as Pili nuts, Brazil nuts and macadamia nuts. Being little known they are not yet consumed in abundance, but are preferable to more common nuts such as cashews and peanuts.
