BHA & BHT are two of the most controversial food preservatives used in everyday products, yet many people are unaware of the health consequences they may pose. Found in everything from snacks to cosmetics, these additives have been linked to both physical and mental health concerns. In this article, we’ll uncover how BHA & BHT can affect your mind and body—and what you can do to protect yourself.

The Hidden Impact of BHA & BHT on Mental Health

In this blog, we explore the hidden dangers in everyday food and cosmetic products — specifically, the preservatives Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT). These synthetic antioxidants, found in everything from chips to makeup, may be more than just shelf-life extenders — they could be harming your physical and mental health.

The Rise of Convenience Foods

Our modern lifestyle craves convenience. As a result, corporations have flooded the market with ultra-processed, quick-prep foods. While these products save time, they often include artificial additives — including BHA & BHT — to preserve shelf life at the cost of your health.

The Hidden Dangers: BHA & BHT

BHA and BHT are phenolic compounds derived from petroleum and used as synthetic preservatives in processed food, snacks, cosmetics, and packaging. Originally developed to prevent oils from going rancid, these compounds are now present in many products you consume and use daily. Read more

Health Concerns Associated With BHA & BHT

While a few studies suggest antioxidant benefits, the majority point to risks. BHA and BHT have been linked to:

• Skin irritation and allergic reactions
• Elevated cholesterol levels
• DNA damage and oxidative stress
• Hormone disruption (especially testosterone)
• Increased cancer risk in animal studies

Impact of BHA & BHT on Mental Health

Emerging research highlights how these additives can impact the brain. Animal studies show structural changes in brain tissue and alterations in neurotransmitter activity. While more human research is needed, the potential implications for anxiety, depression, and mood dysregulation are significant.

When consumed regularly, these preservatives may contribute to inflammation — a known factor in many mental health disorders.
