The Sodium Myth: Why Salt Is Not The Enemy

Salt was demonised for decades.

For active people eating whole foods, the story is more nuanced - and more useful.

Where The Fear Came From

High sodium intake is associated with elevated blood pressure in some populations. Public health guidance responded by recommending universal sodium restriction.

But the picture changes when you look at who is actually at risk - and who is not.

The Processed Food Problem

Most sodium in the modern diet does not come from the salt shaker. It comes from ultra-processed food - bread, sauces, takeaways, snacks, canned soups.

People who eat a whole-food diet and cook for themselves are not the population the sodium guidelines were designed for. Their intake is naturally lower, and the sodium they do consume is balanced by potassium from vegetables and fruit.

Why Active People Need More

Sodium is lost in sweat. If you train hard, run, or live in a hot climate, your sodium requirement goes up - not down.

Under-salting as an active person produces headaches, cramps, low energy, and poor performance. This is not a deficiency you want to fix by eating less salt.

The Practical Approach

• Eat mostly whole foods. This solves 90% of the sodium question automatically.
• Salt your food to taste when you cook. Your palate is a reasonable guide when the food is real.
• If you sweat heavily or train in heat, add salt to your water or eat something salty before training.
• Prioritise potassium too - vegetables, fruit, potatoes, legumes.

Salt is not the enemy. The modern processed food environment is. Distinguish between the two.
