Formal concessions (si bien)

Evaluating Health Claims

Before contrasting ideas, let's look at vocabulary for discussing nutrition, supplements, and health myths.

That supplement is not a miraculous cure.
Ese suplemento no es una cura milagrosa.
The smoothie has many antioxidants and improves digestion.
El batido tiene muchos antioxidantes y mejora la digestión.

Formal Concessions: Si bien

When you want to say "although" or "even though," a slightly more formal alternative to aunque is si bien.

Because it introduces an established fact rather than a hypothetical situation, si bien is followed by the indicative mood.

Even though the antioxidant helps, it is not the cure.
Si bien el antioxidante ayuda, no es la cura.
Although you consume vitamins, your health depends on a balanced diet.
Si bien consumes vitaminas, tu salud depende de una dieta equilibrada.

You can place the si bien clause at the beginning of the sentence, or embed it in the middle of a thought.

It is said that, although the smoothie is healthy, it affects digestion.
Se dice que, si bien el batido es sano, afecta la digestión.

Clarifying with O sea

To clarify a point or rephrase something directly, use o sea (that is / in other words).

Even though the product seems miraculous, it is deceptive, that is, fake.
Si bien el producto parece milagroso, es engañoso, o sea, falso.
