Global health authorities are raising fresh concerns over the widespread use of phosphate additives — including Sodium Hydrogen Phosphate (SHP) — in ultra-processed foods, prompting calls for stricter regulation and clearer labeling. The shift stems from recently updated guidance by a major nephrology association warning of potential health risks associated with high dietary phosphate, especially for individuals with kidney disease.

Kidney-Health Experts Warn of Hidden Phosphate Overload

In late 2025, the American Society of Nephrology (ASN) published new guidance advising patients with chronic kidney disease (CKD) — and high-risk individuals — to minimize intake of foods containing phosphorus and potassium additives. According to the guidance, phosphate additives such as SHP are highly bioavailable, meaning they are absorbed more readily than naturally occurring phosphorus in whole foods. This increased absorption can accelerate mineral imbalance and put strain on compromised kidneys.

The ASN emphasizes that current nutrient labeling practices often fail to disclose exact additive phosphate content, making it difficult for consumers and patients to manage intake effectively. As a result, processed cheeses, frozen meals, deli meats, and other phosphate-rich products — many of which rely on SHP for texture, moisture retention, or emulsification — are under heightened scrutiny. 

Food Industry and Regulators Reassess Additive Use and Transparency

In response to growing health concerns, regulatory authorities in several countries are re-evaluating the allowable levels of phosphate additives in processed foods. The trend echoes broader environmental and health-oriented movements that challenge the long-standing acceptance of phosphate salts in food manufacturing.

Some food producers are already reacting preemptively: formulation teams are investigating reduced-phosphate recipes, natural alternatives, or stricter additive controls — particularly in products targeted at vulnerable populations such as infants, elderly, or those with chronic disease. Market research firms report rising demand for phosphate-free or “low-phosphate” processed foods. 

Importantly, experts clarify that SHP and other sodium-phosphate additives remain allowed under regulatory frameworks — but the shift signals a growing demand for greater transparency, clearer labeling, and consumer choice when it comes to additive use.

What This Means for Consumers, Patients, and Food Manufacturers

For the general public, the renewed focus on phosphate additives like SHP calls for more vigilance: reading ingredient lists carefully, moderating intake of heavily processed foods, and being especially mindful if one has kidney concerns or related health conditions.

For food manufacturers, this development likely means increased pressure to adapt formulations — potentially reformulating products, optimizing additive levels, or offering additive-free alternatives. This transition may also influence sourcing decisions, cost structures, and marketing approaches, especially in regions with growing health-conscious consumers.

For regulators and public-health organizations, the situation underscores the need for updated dietary guidelines, clearer disclosure requirements, and possibly reevaluation of acceptable daily intake thresholds given evolving scientific and clinical data.
