Feed Your Brain

A practice card

What you eat is thought to have some effect on mood and energy, though the effect is modest and varies person to person — not a fix on its own.

When

When mood has felt low or scattered and food is one of several things worth looking at, not the main suspect.

What's actually happening

The gut and brain are connected by nerves and chemical signaling, and diet is thought to influence that connection, along with blood sugar and energy through the day. The evidence is real but modest — food is one input among many, including sleep, stress, and movement, not a lever that moves mood on its own.

What to change

Notice if meals have been getting skipped, and eat something at roughly regular times through the day.

Add one more vegetable or piece of fruit to a meal you already eat, rather than overhauling what you eat.

Notice whether a sugary snack is followed by a low or irritable patch an hour or two later.

Before assuming a low mood is something deeper, check whether you've had enough water today.

If you want to change how you eat in a real way, a doctor or dietitian can help you do it safely.

Where to start

roughly placed · eating something regularly comes first

Pick one

Five at once is how these lists fail. Tap a number — the ones up and to the left give the most for the least.

What to expect

None of this treats a real mood problem, and food is a small lever next to sleep, movement, and support. Pick one of these and try it for two weeks before deciding whether it's made any difference.

choose one, and the fortnight starts
