WHICH NUT IS BEST?

What is a nut?

- From a botanical point of view, stricktily speaking, a nut is a indehiscent dry fruit formed by a single seed surrounded by a hard protection. Hazelnuts, chestnuts and acorns are real nuts

For a fruit to be considered a nut it must not self-open when ripe. That is to say, it must be indehiscent.

- From an edible point of view, it is considered a nut any type of edible seed, non-cereal, surrounded by a crust or hard layer.

Thus, for example, almonds, pecans, pistachios, walnuts or Brazil nuts are considered nuts, although they are not real nuts, botanically speaking.

Which are real nuts?

Among the most important real nuts, we have the following?

- Hazelnuts from hazel trees

- Chestnuts from chestnut trees

- Beechnuts from beeches

- Acorns from oak trees.

Which are not real nuts?

Some fruits are dietetically considered nuts, although they are not botanically nuts. Among them, we have the following:

- A Brazil nut is the dry seed of a nut-shaped capsul that produces the tree of the same name.

- A coconut is a drupe with fibrous "meat" produced by a palm tree. What we eat - the white "meat"- actually is the endosperm or the food reserve of the seed.

- A macadamia nut is actually the seed a follicle fruit that produce the trees of the same name. Inside this fruit they are a couple of seeds with a hard shell.

- Almonds are the seeds not the fruits. In fact, they produce a fleshy fruit (drupe), whose fleshy outer parts become dry in time.

- A walnut, like an almond, is the seeds of a drupe.

- A pistachio is the seed of a drupe.

- A pecan or pecan nut is also a drupe

- A peanut is the seed of a legume (Papilionaceae)

- A cashew is the fruit of a false fruit

- A pine nut is the seed of a pine tree.

MAIN NUTS AND THEIR BENEFITS

Almonds: rich in protein and minerals

Almonds

Almonds

- Almonds: Almonds are the only alkalizing nut, as it provides lots of minerals such as magnesium and calcium. Because of this composition, it is highly recommended to take for osteoporosis, chronic fatigue and fibromyalgia.

This is one of the richest nuts in protein, high percentage of essential amino acids.. Almonds are an ideal complement for vegetarian diets, diets for athletes, growth stages and states of decay and tiredness.

In addition they provide healthy fats, especially omega 9. Scientific studies have shown that consumption of almonds helps reduce cholesterol, prevent stones in the gallbladder and Alzheimer's.

Hazelnuts are rich in fiber and omega 9

Hazelnuts

Hazelnuts

- Hazelnuts: Hazelnuts are very rich in omega 9 and vitamin E, which in addition to the benefits of omega 9, has antioxidant properties.

They are especially recommended for people with heart disease and obesity, as they are also rich in insoluble fiber (nearly 10% of its composition), with cholesterol lowering properties and to satisfy hunger.

Hazelnuts are rich in potassium, phosphorus, magnesium, manganese, but they also contain calcium and iron.

Walnuts, the richest in omega 3

Walnuts

Walnuts

- Walnut: walnuts have received a very important role in nutrition and natural medicine, because they have an extraordinary content of essential omega-3 fats.

The omega 3 is an essential fat, with properties against cardiovascular disease, cancer and anti-inflammatory properties that can help treat menstrual pain and arthritic or joint pain.

No less important is its content in omega 6. Omega 6 fats are also essential and are found in nuts. They have similar anti-inflammatory properties of omega-3.

In recent years there has been given little importance to these omega 6 fats due to the high consumption of seed oils (sunflower oil, sesame oil, etc.), from whom excessive consumption is done through fried and industrial products.

However, both omega-6 fats and omega-3 fats are necessary for the body and have to be found in food, preferably in the form of nuts, and in moderation, through vegetable oils.

Walnuts are recommended for people people with obesity, because a study showed that daily consumption of one serving of these foods for a year, reduced waist circumference of the people involved.

Walnuts also provide high doses of folic acid, an essential vitamin during pregnancy. Also taking walnuts after delivery can improve postpartum depression because it can be caused by a deficiency of omega 3 fats (DHA type).

Coconuts, full of energy and minerals

Coconut

Coconut

- Coconut:Coconut is one of the fruits with the highest content of minerals and trace elements. These components include those that regulate the muscle tone and improve cardiovascular function.

Selenium is part of glutathione peroxidase enzyme, an antioxidant system which counteracts the formation of free radicals in the body, improve immune function and prevents premature aging. It has been observed that vegetables grown in soils rich in selenium provide people with lower incidence of cancer.

Eating foods rich in selenium stimulates the antioxidant activity of glutathione peroxidase. This antioxidant function of Brazil nuts is enhanced further by vitamin E.

We can benefit from the properties of food nuts introducing them periodically, but in moderate amounts of 2-5 Brazil nuts daily.

Brazil nuts are recommended in those cases where one has to increase dietary antioxidants: smokers, cleansing diets, chemical poisoning; and those affectations in which increased vitamin E and antioxidants is recommended: arthritis, fibromyalgia, diet for Parkinson's disease, psoriasis, lupus, Alzheimer's, etc.

Cashews are high in carbohydrates

Cashews

Cashews

- Cashews: Cashews are high in protein and carbohydrates, so, they can be taken in diets that require an input of energy and important amino acids, as in states of stress or students.

Compared to other nuts, cashews are low in fat (40%).
