Early Mycotoxins Exposure: A Hidden Driver Of Cardiometabolic Risk

Area of Science:

• Environmental Health
• Developmental Toxicology
• Cardiovascular Science

Background:

• Mycotoxins are common fungal contaminants in staple foods globally.
• Their role in early-life cardiometabolic disease programming is underrecognized.
• Infants and children are uniquely vulnerable due to developing physiological systems.

Purpose of the Study:

• To review the role of developmental mycotoxin exposure in long-term cardiometabolic risk.
• To highlight key mycotoxins and exposure pathways in early life.
• To summarize the mechanisms linking early exposure to later disease.

Main Methods:

• Review of experimental and epidemiological studies on mycotoxin exposure.
• Analysis of evidence for placental transfer and postnatal exposure routes.
• Synthesis of data on biological mechanisms and health outcomes.

Main Results:

• Developmental exposure to aflatoxins, ochratoxins, fumonisins, zearalenone, and deoxynivalenol is linked to increased cardiometabolic risk.
• Exposure occurs via placental transfer, breast milk, infant formula, and contaminated foods.
• Mechanisms include impaired endocrine signaling, oxidative stress, inflammation, metabolic dysregulation, gut dysbiosis, vascular injury, and epigenetic changes.

Conclusions:

• Mycotoxins are an underrecognized environmental factor in cardiometabolic disease onset.
• Early-life exposure can program susceptibility to obesity, insulin resistance, hypertension, and cardiovascular disease.
• Increased monitoring, risk assessment, and preventive strategies during critical developmental periods are needed.
