Muchas personas vuelven al trabajo después de las vacaciones y recuperan rutinas de comida poco saludables: café con galletas a las siete, un bollo a las diez y, al mediodía, un gran bajón. Se sienten cansadas, irritables y con muchas ganas de comer algo dulce. No es por el estrés ni por falta de café. La causa más habitual está en lo que comieron (o no comieron) en el desayuno.
Ese bajón también afecta al cerebro. Cuando el azúcar baja, el cerebro pide alimentos muy calóricos. Es la química cerebral la que nos empuja a la máquina de chocolatinas. Además, si en el trabajo solo hay comida basura, es más difícil resistirse. Ruiz dice que si hubiera frutos secos o fruta, tendríamos otra opción.
La solución es un desayuno con proteína, grasa y fibra. La proteína es el nutriente que más sacia. Alimentos como huevos, yogur griego, jamón o frutos secos mantienen el azúcar estable. Si añadimos fibra, como avena integral, la subida de glucemia es más lenta. Para quien no quiere desayunar pronto, la clave es preparar algo saludable para media mañana antes de que llegue el bajón.

Watch out, English speaker
English speakers often use 'if' + present tense for real conditions, just like Spanish 'si' + present indicative. But remember: Spanish uses the present subjunctive in hypothetical 'if' clauses, not the conditional. So never say 'Si tendría frutos secos' — it must be 'Si tuviera frutos secos'. Also, the main clause uses the conditional, not the present.
In English, 'if' + past subjunctive (e.g., 'If I had nuts') can refer to the present or future unreal situation. Spanish uses the imperfect subjunctive ('tuviera') for the same meaning, but the main clause must be in the conditional ('tendríamos'), not the present. English speakers might mistakenly use the present indicative after 'si' in unreal conditions, but Spanish strictly requires the imperfect subjunctive.

Grammar spotlight
Conditional sentences: si + present indicative
A2
This structure expresses a possible condition that can be realized. The pattern is 'Si + present tense, main clause in present/future/imperative'. For example, Si comes azúcares, el cuerpo te pide más (If you eat sugars, your body asks for more).
“Si añadimos fibra, la subida de glucemia es más lenta.”— If we add fiber, the rise in blood sugar is slower.
⚠️ Do not use the subjunctive in the main clause; the si clause simply takes the present tense.
Hypothetical conditional sentences: si + imperfect subjunctive
B1
This structure expresses a hypothesis contrary to current fact. The pattern is 'Si + imperfect subjunctive, main clause in conditional'. For example, Si hubiera frutos secos, tendríamos otra opción (If there were nuts, we would have another option), implying there actually aren't any.
“Si hubiera frutos secos o fruta, tendríamos otra opción.”— If there were nuts or fruit, we would have another option.
⚠️ Do not confuse the conditional in the main clause with the subjunctive in the si clause; the si clause cannot use the conditional.

Spain's Sweet Breakfast Culture
In Spain, traditional breakfasts are often sweet: a small roll (bollo), cookies (galletas), sweetened coffee, or juice. Although this breakfast is convenient and tasty, it is high in sugar and can easily cause blood sugar fluctuations during the morning. Nutrition experts recommend gradually shifting to a savory breakfast, such as eggs, ham, or yogurt with nuts, to maintain steady energy.
