Trichoderma is a widely dispersed allergen that can grow in various environments across the United States. It particularly thrives in warm and humid climates and is often found in soil, decaying wood, and other organic matter.

Trichoderma Growth in Different Regions

• South and Southeast: Trichoderma is very commonly found in the southern and southeastern regions of the US that have warm, humid climates. It can be found in outdoor soil and decaying plant matter.
• Midwestern and Eastern States: In states with more temperate climates such as those in the Midwest and East, Trichoderma is generally found indoors, typically in damp basements or moist areas in homes.
• Western and Northern States: In the colder northern and western states, Trichoderma can still grow but is less common than in warmer climates. It is more often found indoors in these regions.

It’s important to note that Trichoderma is a versatile species that can be found across all states within the US, but its prevalence may increase or decrease based on specific climate conditions.

While there is no specific research indicating that certain foods can worsen Trichoderma allergy symptoms, some foods have been known to exaggerate asthma and other allergic reactions. Each person’s reaction to food may differ, but there are few items that commonly cause issues.

Foods to Avoid (Common Allergens)

• Dairy products: This includes things like milk, cheese, and yogurt. Dairy can increase the production of mucus in some people, which can aggravate respiratory allergy symptoms.
• Eggs: Eggs are a common allergen and have been known to trigger symptoms in some individuals with allergies or asthma.
• Processed Foods: These foods often contain preservatives and additives that can trigger allergy symptoms.
• Sulphites: Commonly found in wine, beer, dried fruit, canned goods, and some processed meats, sulfites can cause allergy-like reactions in some people.

However, it’s necessary to understand that these are generalizations, and individual reactions to food can differ. If you suspect a food is causing or aggravating your Trichoderma allergy, it's essential to speak with a healthcare professional who can guide you in identifying problematic foods and maintaining a balanced diet.
