Among them, there are various polyphenols that help us fight oxidative stress and reduce free radicals that cause cell damage.

There are several scientific studies that have concluded the benefits of nuts with a daily consumption of 25 to 30 grams [Study 1] [Study 2].

These benefits, however, are not as conclusive in sick or elderly people, where antioxidant markers did not show great changes with moderate consumption of nuts.

Contribute to body weight control

The balanced diet allows us to control body weight based on eating, of great variety, small amount.

The fact of being able to take nuts, for example, as an appetizer before meals, allows us to increase satiating power and reduce the intake of carbohydrates and subsequent saturated fats.

Therefore, the effect to control weight is not direct nor is it associated with the consumption of nuts and their activity in the digestive system. However, yes indirectly by allowing to reduce, based on being more satiated, the consumption of less healthy foods.

As for the properties of walnuts to control bad cholesterol, there are several studies that have linked a remarkable drop in cholesterol levels after the periodic intake of 25 to 30 grams of nuts daily. [Study]

This has shown an important effect in controlling LDL cholesterol levels and triglycerides. Similarly, it also happens with other nuts such as pistachios and almonds.

New studies have tried to link the decline in triglyceride levels in a framework of obese population, obtaining a reduction of dichlevels above 30% in 12 weeks (3 months). [Study]

The explanation of the effect of the properties of walnuts are due to their content in monounsaturated and polyunsaturated fatty acids, which act with a positive response for the body, balancing and reducing the levels of LDL cholesterol against the elevation of the considered as good (HDL).

Properties of anti-inflammatory nuts

Moreover, there is chronic inflammation of tissues that causes organ damage and increases the risk of disease. Therefore, this is where research is focused, trying to answer the question of whether the properties of walnuts have anti-inflammatory potential.

Several scientific investigations have been developed where credibility is given to the anti-inflammatory action of the properties of nuts. [Study].

This can have an impact on reducing the risk of contracting diseases and reducing cellular aging.

The properties of walnuts they can also be applied to other nuts, such as Brazil nuts, almonds and pistachios, where clinical trials have shown similar levels of efficacy.

In fact, the nuts they are one of the most interesting foods for those people who suffer from metabolic syndrome along with type 2 diabetes.

Nuts are low in carbohydrates and do not excessively increase blood sugar levels (low glycemic index). Therefore, we can increase the consumption of nuts and reduce those foods that have a high concentration of carbohydrates to reduce the level of sugar in the blood.

Scientific studies link regular nut consumption to reduced oxidative stress, as well as lower blood pressure and other markers in people suffering from diabetes and metabolic syndrome [Walnuts and oxidative stress]

High fiber content

The daily intake of 30 grams of nuts gives us about 3 grams of fiber. It has been scientifically proven that maintaining a high fiber intake causes health benefits, both at the digestive level and at the cardiorespiratory level.

Among the benefits of high fiber intake are a significant improvement in intestinal health, reducing obesity and combating diabetes. [Study]

Fiber content of the main nuts on the market.

Fiber concentration for 30 grams recommended daily.

How many nuts can I take a day?

It is considered appropriate to consume a daily serving of nuts with an amount of 30 g. This, in walnuts, is equivalent to 3 or 4 a day, the amount of which will have to be reduced if we also introduce other nuts such as almonds or pistachios, for example.

It is advisable to acquire those nuts that have low salt content and do not have additives. In fact, in the case of almonds, it is advisable to take them even with skin, since they are a source of fiber.
