Is Bicarbonate of Soda Healthy?

Everyday Uses in the Kitchen and Home

Most of us keep a box of bicarbonate of soda stashed in a kitchen drawer, ready to help cookies rise or mop up minor spills. Growing up, my grandmother would sprinkle it into cake batter and swear by its power to keep the fridge smelling fresh. This familiar white powder has been trusted for years because it’s both cheap and reliable. But people keep asking if it’s actually healthy to eat, especially outside baking and cleaning.

Health Claims and Everyday Habits

It's become common to hear wellness influencers suggesting a spoonful of bicarbonate of soda mixed with water to soothe heartburn or improve stomach health. The logic follows that neutralizing stomach acid might bring relief for acid reflux or indigestion. Medical research backs this up—sodium bicarbonate does reduce stomach acid, so a person dealing with heartburn might get temporary help using it this way. Doctors have long used it in emergency care for certain cases of acid poisoning because of this effect.

Where things tip into questionable territory is the trend of daily consumption for “alkalizing the body.” No solid science backs this idea. Blood pH stays tightly controlled no matter how much baking soda ends up inside the system. Outside the stomach, raising alkalinity by any real measure just doesn’t happen with food or drink.

Hidden Dangers and Everyday Risks

Down-to-earth advice says moderation matters. Baking soda contains a lot of sodium—over 1,200 milligrams per teaspoon, about as much as half a day’s sodium allowance. High sodium raises the risk for hypertension, strokes, and heart problems over time. Swallowing baking soda to manage heartburn, without tracking quantity, can lead to more harm than good, especially for anyone on a salt-restricted diet.

Using baking soda now and then may not cause harm for most healthy adults. But things head south quickly if someone takes it in large amounts by accident or on purpose. I remember a neighbor trying an online “cleanse,” who ended up feeling nauseous and dizzy—too much sodium in the blood can lead to headaches, confusion, and in rare cases, even life-threatening complications.

Children face more serious risks since their bodies handle sodium much less efficiently. For those with chronic illnesses, kidney problems, or who take certain medications, using it without medical advice may cause dangerous shifts in body chemistry.

Better Solutions for Common Problems

There’s wisdom in tried-and-true kitchen remedies, but new habits should come after looking at the full picture. If heartburn hits more than once in a while, pay attention to overall diet and portion sizes. Doctors suggest raising the head of the bed at night, cutting out foods that trigger reflux, and seeking medication if lifestyle tweaks don't relieve symptoms. Bicarbonate of soda comes in handy as an occasional fix, not a daily supplement.

For keeping food fresh and cleaning stubborn stains, this powder works great—no need to nibble it. Baking soda can stay in its place as a handy household chemical, best used with care and a good dose of common sense.
