Erythritol

A zero-calorie sugar alcohol that provides bulk and sweetness with minimal impact on blood sugar and insulin; mostly absorbed and excreted unchanged in urine.

Category: Additive
Subcategory: Sugar Alcohols
Processing Level: 8
Source: Corn or wheat starch
Purpose: Zero-calorie bulk sweetener and humectant.
Manufacturing Method: Microbial fermentation with purification
Why Manufacturers Choose It: Delivers clean, sugar‑like sweetness and bulk with near‑zero calories and wide global approval.
Commonly Found In: ["tabletop blends","keto candy","protein bars","sugar-free gum","beverages"]
Health Score: 7
Bottom Line: Erythritol can meaningfully cut added sugar without spiking blood sugar, but it is a highly refined, fermentation‑derived sweetener that often causes diarrhea at large single doses. Keep portions modest (stay well below ~0.5 g/kg/day) and avoid big bolus drinks or candies—especially if you have cardiovascular risk.
Healthier Alternatives: Honey, Inulin, Dates

Palm oil

A semi-solid vegetable oil pressed from oil palm fruit; refined palm oil is neutral-tasting and shelf-stable, while unrefined “red” palm oil retains carotenoids and vitamin E.

Category: Fats & Oils
Subcategory: Plant Fats
Processing Level: 6
Source: Oil palm fruit
Purpose: Semi-solid plant fat that provides structure and oxidative stability in foods.
Manufacturing Method: Pressed, refined (RBD), fractionated
Why Manufacturers Choose It: Low cost, neutral flavor, and reliable semi-solid texture without hydrogenation.
Commonly Found In: ["Protein bars","Cookies","Baked snacks","Spreads","Creamers"]
Health Score: 5
Bottom Line: Most products use refined palm oil, which behaves like a saturated‑fat source and raises LDL compared with unsaturated oils—so keep it limited and read saturated fat on the Nutrition Facts panel. If you want nutrients from palm, choose clearly labeled red palm oil; otherwise, opt for items that use more unsaturated oils and ensure refined palm oil is well‑controlled for 3‑MCPD/glycidyl esters.
Healthier Alternatives: High-oleic sunflower oil, Cocoa butter, Avocado oil (high-oleic)

Sodium caseinate

Milk-derived protein salt used to add protein and to stabilize/emulsify foods.

Category: Dairy
Subcategory: Caseins
Processing Level: 8
Source: Cow's milk casein
Purpose: Complete milk protein that emulsifies and stabilizes foods.
Manufacturing Method: Acid-precipitate casein, neutralize with NaOH, dry
Why Manufacturers Choose It: It delivers high-quality protein with excellent emulsifying performance and heat stability at a competitive cost.
Commonly Found In: protein powders, coffee creamers, bars, processed cheese, ice cream
Health Score: 8
Bottom Line: Sodium caseinate is a milk‑derived protein salt used to add protein and keep foods stable, and it is broadly considered safe. The main tradeoffs are added sodium and that it is a refined dairy ingredient.
Micronutrients: ["Calcium","Phosphorus","Sodium"]
Antioxidants: []
Healthier Alternatives: Milk protein isolate, Whey protein concentrate, Micellar casein

Glycerin

A clear, sweet, syrupy liquid that holds water (a moisture-attracting compound called a humectant) and helps keep foods soft, moist, and stable.

Category: Additive
Subcategory: Other
Processing Level: 8
Source: Fats and oils
Purpose: Humectant and solvent that holds moisture, softens texture, and carries flavors in foods.
Manufacturing Method: Natural derivative with refined purification
Why Manufacturers Choose It: It reliably keeps products moist with neutral taste, consistent specs, and low cost.
Commonly Found In: ["Protein bars","Icing/frosting","Chewing gum","Dried fruit","Beverages"]
Health Score: 8
Bottom Line: Glycerin is a highly refined derivative of fats and oils and is considered safe at typical amounts. The real‑world risks are big, rapid servings (notably some slush drinks) and off‑spec supply—pace intake, especially for kids, and stick to products using verified food/USP‑grade glycerin.
Healthier Alternatives: Honey, Inulin, Date paste
