Is sodium bicarbonate high in sulfites?

Watch for

• Sodium is the real story.A single teaspoon of sodium bicarbonate supplies around 1,260 mg of sodium, which is most of a full day on a 1,500 mg target and roughly half a day at 2,300 mg. If you track blood pressure, fluid retention or puffiness, this belongs in the log as a sodium event
• Dose-related gut upset is the best documented effect.Bicarbonate loading protocols used before exercise are typically 0.2 to 0.3 g per kg of body mass, and bloating, cramping, nausea and diarrhoea within 60 to 90 minutes are common enough that athletes split the dose or take it with a meal
• It hides under several names.Bicarbonate of soda, sodium hydrogen carbonate and E500 are the same compound, and self-raising flour, soda bread, effervescent and soluble medicines all carry it. Soluble and dispersible tablets in particular can carry a surprising sodium load per dose
• Our sheet grades sodium bicarbonate borderline for salicylate and oxalate.Read those as caution flags on a processed additive rather than as content: a purified inorganic salt contains no plant secondary compounds, so it cannot supply salicylate, oxalate, lectins or fermentable carbohydrate
• Raising the pH of a food changes it.Bicarbonate in cooking water softens legumes and vegetables and deepens browning in baked goods, but it also degrades some heat-sensitive vitamins such as thiamine and vitamin C, which is a nutrition note rather than a trigger one
