Each individual must meet nutritional requirements to offset expenses and losses related to the functioning of his body. These requirements depend on age, sex, weight, physical activity of each ...



A healthy, balanced diet enables us to meet our needs by providing:

- Macronutrients: that is to say, carbohydrates, lipids and proteins (according to their proportion, the dried fruit has a certain energy value expressed either in calories or in Kj)

- Micronutrients: vitamins and minerals commonly called.



The nutritional charts show the average composition of essential nutrients contained in the main nuts: Components Energy, Fibre, Minerals and Vitamins.





Detailed explanations of the benefits of each nutrient:



All foods are made of a certain proportion of carbohydrates, lipids and proteins (proteins). They provide energy to our body.



Carbohydrates

- Source of energy (1g carbohydrate = 4 kcal)

- Preferably used by brain cells and red blood cells (the brain consumes the equivalent of 5g of sugar per hour)



Lipids:

- Source of energy (1g fat = 9 kcal)

- Constituents of cell membranes and sex hormones

- Essential components of the brain and nervous system

- Intake of essential fatty acids



Proteins:

- Source of energy (1g protein = 4 kcal)

- Agents of growth, maintenance and renewal of cells

- Constituents of hormones

- Essential for immune system: antibodies



In addition, minerals and vitamins are substances essential for the proper functioning and growth of the organism. It is therefore important to eat regularly.



Iron:

- Involved in the transport of oxygen to tissues and carbon dioxide to the outside



Magnesium:

- Participates in numerous enzymatic reactions

- Necessary for bone metabolism and muscle contraction



Phosphorus:

- Forming the skeleton and teeth



Calcium:

- Forming the skeleton and teeth

- Essential for strong bones



Vitamin A:

- Used in the mechanism of vision

- Allows the upkeep of the skin and mucous membranes



Vitamin B1

- Allows the use of carbohydrates

- Allows the proper functioning of the nervous system



Vitamin B2

- Allows the use of carbohydrates, lipids and proteins



Vitamin B9

- Used in the process of cell multiplication

- Allows the proper functioning of the nervous system



Vitamin E:

- Helps prevent oxidation of components of lipid-rich cells

The fibers are non-degradable carbohydrate components during digestion, but which have important functional roles:

- Waste disposal and bacterial bodies

- Regulation of intestinal transit

- Modified flora

- Modified the absorption of carbohydrates.



The allegations, "high" and "Source":



To be aware that to mention a vitamin or mineral on the label of a product requires that it covers at least 15% RDA * (recommended daily intake) per 100g of product.

Then, depending on the percentage using one or other of the terms "rich" or "source".

A good "source of ..." covers at least 15% RDA of a certain vitamin or a mineral.

Ex: figs are a source of calcium for 100g figs cover 20% RDA of calcium.



A product "rich in ..." should cover at least 30% RDA of a certain vitamin or a mineral.

Ex: almonds are rich in magnesium as 100g almonds covering 83% RDA of magnesium.
