Answer: Sodium Aluminum Phosphate is restricted (not fully banned) in European Union (restricted in baby food and specific food categories), Australia (restricted levels). The FDA still allows it in US food. Commonly found in: Pancake mixes, Self-rising flour, Some baking powder formulations.
TL;DR: Sodium Aluminum Phosphate is restricted in the EU but allowed in the US (food additives).

Sodium aluminum phosphate (SALP) is a leavening acid and food additive used in baked goods, particularly self-rising flour and baking powder. It provides a slow, sustained leavening action during baking. SALP is also used as an emulsifying salt in processed cheese products.
SALP is used as a slow-acting leavening acid in baked goods, releasing carbon dioxide slowly during baking for a light texture. As an emulsifying salt in processed cheese (American cheese, Velveeta), it helps create a smooth, melt-friendly texture.
The primary health concern with SALP is aluminum exposure. Dietary aluminum intake has been studied in relation to neurotoxicity, and there is ongoing scientific debate about whether chronic dietary aluminum exposure contributes to Alzheimer's disease risk. EFSA's 2008 review of dietary aluminum exposure concluded that the tolerable weekly intake (TWI) was being exceeded by some European populations based on total dietary aluminum sources, raising concern. A 2011 EFSA risk assessment noted that certain high-aluminum sources (including baked goods from SALP-containing leavening agents) contributed meaningfully to total dietary aluminum. The WHO has set a PTWI (provisional tolerable weekly intake) of 2 mg/kg body weight/week for total aluminum. However, the causal link between dietary aluminum from food-grade SALP and Alzheimer's disease has not been definitively established in human studies.

Non-aluminum leavening acids including monocalcium phosphate (MCP), sodium acid pyrophosphate (SAPP), and cream of tartar provide leavening without aluminum exposure. Many baking powder brands now offer aluminum-free formulations (Rumford, Bob's Red Mill).
FDA classifies it GRAS. EFSA has noted concern about total aluminum dietary intake exceeding the tolerable weekly intake in some populations. The aluminum-Alzheimer's link has not been proven but warrants precaution.
SALP is a leavening acid in baking powder and self-rising flour that slowly releases CO2 during baking. It is also used as an emulsifying salt in processed cheese.
A definitive causal link between dietary aluminum from food-grade SALP and Alzheimer's disease has not been established. Elevated aluminum has been found in Alzheimer's brain tissue, and some researchers maintain concern, but the broader scientific consensus is that the evidence is insufficient to establish causation.
Choose aluminum-free baking powder brands like Rumford or Bob's Red Mill. Check baking powder ingredient labels for sodium aluminum phosphate or sodium aluminum sulfate.
American cheese singles, Velveeta, and other processed cheese products use emulsifying salts including SALP to achieve their characteristic smooth, meltable texture. Natural cheeses do not contain SALP.
Not outright banned, but the EU restricts it in baby food and some food categories based on concerns about infant aluminum exposure.

Natural cheese (cheddar, swiss, mozzarella) contains no SALP or emulsifying salts. Processed cheese products (American cheese, Velveeta) use emulsifying salts including SALP to create their meltable, stable texture. Natural cheeses are generally considered preferable for minimizing SALP and aluminum exposure.
Some natural cheese products and fresh cheeses can serve as processed cheese substitutes. Organic and natural food brands tend to use less or no SALP. Making homemade cheese sauces with natural cheddar avoids SALP entirely.
