Mars Bar
A sugar-dense confectionery bar with very little nutritional value, high in sugar and saturated fat, best treated as an occasional indulgence.
Ingredients (13)
Sugar
It is the first ingredient and the main component by weight. High free sugar intake is linked to dental decay, weight gain, and increased risk of type 2 diabetes.
Glucose Syrup
A highly refined sweetener that is rapidly absorbed and spikes blood sugar. It adds sweetness and chewiness but has no nutritional benefit.
Skimmed Milk Powder
A source of milk protein and some calcium. It is a simple, minimally processed dairy ingredient. Not suitable for those with milk allergy.
Cocoa Butter
A natural fat from cocoa beans that is high in saturated fat. Its main fatty acid, stearic acid, has a relatively neutral effect on cholesterol, but the total amount is still significant.
Palm Oil
ControversialHigh in saturated fat and linked to deforestation concerns when not sustainably sourced. Mars states it uses RSPO-certified palm oil, but it is still a calorie-dense, nutrient-poor fat.
Cocoa Mass
Ground cocoa beans that provide flavour and small amounts of antioxidants (flavanols). The amount is low and diluted by the sugar.
Lactose and Whey Permeate (from Milk)
Cheap dairy-derived fillers that add sweetness and texture. They are not harmful in small amounts but contribute extra sugars and are a concern for the lactose intolerant.
Milk Fat
A natural dairy fat that is high in saturated fat. It provides a creamy texture and is acceptable in moderation.
Barley Malt Extract
A sweet, flavourful extract from malted barley. It is natural but is a concentrated sugar source, and it contains gluten so is unsuitable for coeliacs.
Salt
Present in small amounts for flavour balance. It is not a concern at this level.
Egg White Powder
A natural protein used to give the nougat its aerated, chewy texture. It is safe except for people with egg allergy.
Emulsifier (Soya Lecithin)
E322A widely used and well-studied emulsifier derived from soybeans. It is considered safe by EFSA and FDA, though soy-allergic individuals should be aware of it.
Natural Flavourings (Vanilla Extract)
Used in tiny amounts for flavour. Natural flavourings are generally considered safe, although the term can be vague.
