Macronutrient Breakdown
NUTRITIONIST'S INSIGHT
At 20g protein per 100g, these slices match or exceed the protein density of many conventional chicken deli products. The very low carbohydrate content (2.5g/100g) means negligible glycemic load — ideal for blood sugar management. However, the sodium is notable at 1.45g salt per 100g (equivalent to ~580mg sodium), so portion awareness matters for anyone watching cardiovascular risk. The added iron (51% RI per 100g) and vitamin B12 (36% RI per 100g) address two common vegan micronutrient gaps, making this a nutritionally thoughtful product rather than just a meat swap.
Myth Busters
MYTH #1: Plant-based deli slices are lower in protein than real chicken
TRUTH: THIS Isn't Roast Chicken delivers 20g of protein per 100g — comparable to roasted chicken breast deli meat (typically 22–25g/100g). The soy-wheat-pea protein blend provides all essential amino acids. THIS™ Official Product Page; Texturization Science in Plant-Based Meats (PMC, 2023)
MYTH #2: This product is high in carbs like most processed foods
TRUTH: Each 95g pack contains only 2.4g of total carbohydrates with 0.1g sugars — exceptionally low for a ready-to-eat deli product. Blood sugar impact is negligible. THIS™ Official Product Page; Soy Protein Foods and Glycemic Response (Wolever et al., 2006, PMC)
MYTH #3: Soy in plant-based products causes hormonal disruption
TRUTH: Multiple systematic reviews confirm that soy isoflavones at dietary levels do not disrupt thyroid function or sex hormones in healthy adults. The concern stems from isolated animal studies at doses far exceeding typical food intake. Soy Isoflavones and Hormonal Health: Systematic Review (Messina, Nutrients, 2016)
MYTH #4: Ultra-processed plant-based meat alternatives are less healthy than conventional deli meats
TRUTH: Current evidence shows plant-based deli meats compare favourably to conventional processed meats on saturated fat and cholesterol. THIS product has only 1.1g saturated fat per 100g vs. typical chicken deli at 0.5–2g and conventional red-meat deli products at 3–8g.

How to flatten the spike
- Keep the portion to the labelled serving and avoid eating straight from the bag or tray.
- Pair it with a protein or fibre source, such as Greek yogurt, eggs, lentils, beans, salad, or edamame, when you want steadier appetite and glucose control.
- Avoid pairing it with sugary drinks; choose water, unsweetened tea, or coffee so the snack does not become a larger sugar load.
Cultural Significance
THIS™ launched in 2019 as one of the UK's most vocal advocates for realistic plant-based meat. The Roast Chicken Deli Slices are positioned squarely in the UK Sunday roast tradition — replicating the comfort of leftover roast chicken sandwiches without any animal product. The brand's irreverent naming convention ('THIS Isn't...') has become a cultural shorthand for the second generation of plant-based products: ones that compete directly with their meat counterparts on taste, texture, and protein rather than asking the consumer to compromise. Available at Waitrose, Sainsbury's, and other major UK retailers, the product reflects broader shifts in flexitarian eating patterns across British food culture.
