Frequency: It is not necessary to consume them daily. 3 or 4 cans a week (on alternate days) is enough to cover additional calcium needs at this stage.
The magic supplement: Whenever you consume sardines, half an hour later eat a food rich in vitamin C (such as a kiwi or an orange). This transforms collagen from the spines into collagen usable for the joints.
Caution with salt: Always opt for the version without added salt or in olive oil. If you have hypertension, drain them well and rinse them lightly under the tap to eliminate excess sodium without losing their properties.
Movement: Remember that calcium does not travel alone. To enhance this effect of food, take short walks for 20 minutes after eating. The gentle impact and sunlight activate the vitamin D you have ingested.
Forget the myths; Nature, in its simplest and most economical form, remains the best pharmacy. You just have to know how to open the correct can.
