Yo Yo Milk Chocolate Biscuit

A tasty chocolate-coated biscuit treat, but high in sugar and saturated fat, so it's best as an occasional indulgence rather than a regular snack.

I assumed 'yoyo' means McVitie's Yo Yo chocolate biscuit. If you meant another product (e.g. a yogurt or fruit snack), please give the full name or a barcode. Figures are approximate and recipes vary by country.
High in saturated fat: one biscuit provides around a quarter of the recommended daily limit.
Contains palm fat, which may be a concern for environmental reasons unless RSPO-certified.
Allergens: contains wheat (gluten), milk and soy. It may also contain traces of other allergens, so check the label.
Ultra-processed food that is easy to overeat; the sugar and fat content adds up quickly.
Full Analysis

Ingredients (11)

Sugar

aka Table sugar

Sugar is the main ingredient in both the coating and the filling. Frequent high intake is linked to weight gain, dental decay and raised type 2 diabetes risk.

Daily Intake — Roughly 10g sugar per biscuit, about 11% of the daily limit for adults
HIGH RISK

Vegetable fats (palm, shea)

Controversial
aka Palm fat / shea fat

Palm fat is high in saturated fat, which raises LDL cholesterol when consumed in excess. Palm oil sourcing is also linked to deforestation unless certified sustainable.

Daily Intake — About 5g saturated fat per biscuit, roughly 25% of the daily limit
HIGH RISK

Wheat flour (fortified)

aka White flour

Refined flour provides little fiber and is digested quickly. It is fortified with calcium, iron and B vitamins, but those don't offset the overall nutritional profile.

Daily Intake — Refined carbohydrate that contributes to the high glycemic load
MODERATE

Cocoa mass / cocoa powder

aka Cocoa

Cocoa contains flavanols and minerals like magnesium and iron. The amount here is fairly small compared with the sugar and fat.

Daily Intake — None at typical serving sizes
SAFE

Whey powder (milk)

aka Milk by-product

A cheap dairy ingredient that adds flavor and texture. It is not harmful for most people, but it is an allergen and a marker of a processed recipe.

Daily Intake — Contains milk allergen
MODERATE

Skimmed milk powder

aka Dried milk

Provides a small amount of protein and calcium. It is a simple, well-understood ingredient.

Daily Intake — Contains milk allergen
SAFE

Rapeseed oil

aka Canola oil

Lower in saturated fat than palm and a source of unsaturated fats. It is a reasonable fat choice in baked goods.

Daily Intake — None at typical serving sizes
SAFE

Soya lecithin

E322
aka Soy emulsifier

A widely used natural emulsifier that is considered safe at food levels. The main concern is soy allergy.

Daily Intake — Contains soy allergen
SAFE

Raising agents (sodium bicarbonate, ammonium bicarbonate)

E500, E503
aka Baking soda and baking ammonia

Common leavening agents that break down during baking. They are regarded as safe by EFSA and the FDA.

Daily Intake — None at typical serving sizes
SAFE

Salt

aka Sodium chloride

The amount per biscuit is low, but it adds up with other snacks and processed foods across the day.

Daily Intake — About 0.13g per biscuit, roughly 2% of the daily limit
MODERATE

Flavouring

Controversial
aka Added flavor compounds

The exact compounds are not disclosed on the label. They are regulated and generally safe, but they indicate an ultra-processed product.

Daily Intake — None specific
MODERATE
