Uno de cada cinco españoles consumen suplementos dietéticos, en forma de jarabes, pastillas o enriquecimiento de productos de consumo como la leche o los zumos “enriquecidos con...”.
¿Sirve de algo?
Depende de para quién:
· Sí, de muchísimo, para las multinacionales de la alimentación, algunas empresas farmacéuticas, herboristerias, etc.
· No, un rotundo no, para los consumidores en general. Hay excepciones y, salvo que se me olvide alguna, que seguro que se me olvida, estas son:
1. Durante el embarazo puede hacer falta un aporte extraordinario de ácido fólico o calcio.
2. Durante la lactancia hay que aumentar el consumo de calcio.
3. En dietas de adelgazamiento muy rigurosas de menos de mil Kcal al día.
4. En pacientes ancianos que no estén haciendo una dieta adecuada.
5. En personas vegetarianas que no hagan correctamente este tipo de alimentación.
6. En determinado tipo de anemias por déficit de hierro, vitamina B12 o ácido fólico (faciles de detectar en todos los casos con un simple análisis de sangre).
7. En personas con una Osteoporosis comprobada es necesario un aporte extra de Calcio y Vitamina D.
Problemas con los suplementos
· Las vitaminas hidrosolubles como la vitamina C, B1, B2 o ácido fólico, no causan ningún problema pues, el exceso, es secretado por la orina. La única contrariedad es que estamos pagando por orinar vitaminas.
· Las vitaminas liposolubles: A, D, E, K, no se excretan cuando se consumen en exceso sino que se depositan en el hígado y, a la larga , pueden producir problemas de salud.
· Los minerales, en exceso, también pueden provocar problemas de salud, como hipertensión con el sodio, cálculos en el caso del calcio, Osteoporosis con el fósforo o transtornos cardíacos con el potasio, por poner sólo algunos ejemplos.
Ventajas de los suplementos en personas sanas
Ninguna, ni en deportistas siquiera. No se está ni más sano ni más fuerte, ni se tienen menos resfriados ni la piel más maravillosa.
Con una dieta normal se obtienen suficientes nutrientes de todo tipo para una vida sana. Incluso haciendo una mala alimentación, será muy difícil que haya un déficit y, si lo hubiera, daría los síntomas que pondrían en alerta, como el cansancio en la anemia por déficit.
No me sea cazurro. Coma bien, que no es tan difícil.
La insufrible polarización
