Children love chocolate despite the fact that it is unhealthy, as we all know. Why is chocolate unhealthy? Which harmful chemicals are used in it? This page will go into great detail about each of those dangerous ingredients.

Most common ingredients used in chocolates

1. Sugar: Primary Culprit

Sugar is used to improve taste, sweetness, and shelf life.

Long-term excessive sugar consumption can lead to weight gain, tooth decay, raised blood pressure and insulin levels, joint pain, skin aging, liver damage, type 2 diabetes, pancreatic breakdown, kidney failure, and increased heart attack risk.

WHO recommends <10% of daily calories from sugar (≈25g/day for an adult).

Most of the chocolates available in the market have 15g–25g of sugar per 35g bar—already hitting your daily limit.

Reference: WHO – Guideline, Sugar intake for adults and children, World Health Organization, 2015

2. Refined Palm Oil / Hydrogenated Fats

Palm oil is around 50% saturated fat. Palm oil is very cheap and does not spoil for a long time (a cheaper substitute for cocoa butter); most of the food in Indian markets is made with this palm oil.

Palm oil is high in saturated fat, raises the bad cholesterol (LDL), and decreases good cholesterol (HDL). Very harmful for heart health.

Globally, India is the leading importer of palm oil in 2023. India imported $8.7 billion worth of palm oil. Ranking first among 206 countries. Imported from Malaysia and Indonesia.

Reference: American Heart Association.

3. Milk Solids/Milk Powder

Milk solids or powder Used for creamy texture and dairy base.

Source of calcium and protein. It can create problems for lactose-intolerant or allergic individuals. promote inflammation when ultra-processed.

4. Emulsifiers (E322 – Lecithin, E476 – Polyglycerol Polyricinoleate, PGPR, E476)

Generally, emulsifiers are used to improve texture and prevent separation of ingredients. Polyglycerol Polyricinoleate (PGPR, E476) is sometimes used as a cheaper alternative to cocoa butter.

E476 (PGPR) is petroleum-derived and may create gut problems. In some animal studies, it’s linked to liver enlargement and digestive issues.

5. Artificial Flavors (Vanillin, Ethyl Vanillin)

Used as an alternative to natural flavors. Imitates real vanilla at a lower cost.

Often synthesized from petrochemicals like guaiacol. Can create problems for allergies and migraines (headaches) in sensitive individuals (especially in children).

6. Cocoa Solids (Low Percentage)

Cocoa solids are used for chocolate flavor.

Most commercial chocolates contain only 6%–12% cocoa (that is too low). Real dark chocolate should have ≥70% cocoa.

Low-quality cocoa can be contaminated with toxic heavy metals like cadmium and lead, especially if sourced from polluted soil or processed improperly. Cadmium and lead can create many problems for health, like kidney damage, bone demineralization, impaired child brain development, etc.

We will discuss ‘Dark Chocolate’ in detail on another page.

7. Preservatives & Stabilizers (E330 – Citric Acid, E200 – Sorbic Acid)

Preservatives & stabilizers are generally used to extend the shelf life of products.

Industrially produced citric acid may be linked to inflammation in sensitive individuals.
