Nuevas Investigaciones Amplían las Capacidades de la Nutrición Personalizada

Usted es tan único, que su singularidad representa una en 400 billones de posibilidades. Entonces, ¿cuáles son las posibilidades de que usted pueda necesitar las mismas recomendaciones nutricionales?

Fruta Entera Versus Jugo De Fruta: Somos Lo Que Comemos (Y Lo Que Bebemos)Whole Fruit Versus Fruit Juice: You are What You Eat (and Drink)

En un nuevo estudio llevado a cabo en USANA Health Sciences y publicado en la revista Nutrients, los científicos han demostrado que lo que comemos (o lo que bebemos) puede tener un impacto significativo. De hecho, puede afectar la manera en que nuestros genes son regulados, ya sea que se activen o que se desactiven.
