Natural Dietary Sources While plant sterols occur naturally in many foods, typical diets only provide around 200–400 mg per day:
-
Vegetable Oils: Unrefined canola, corn, soybean, and olive oil.
-
Nuts & Seeds: Sesame seeds, pistachios, almonds, and sunflower seeds.
-
Legumes & Grains: Wheat germ, rice bran, chickpeas, and lentils.
-
Fruits & Vegetables: Passionfruit, avocados, broccoli, and Brussels sprouts.

How They Work : Plant Sterols
-
Intestinal Competition: Plant sterols bind to digestive micelles in the small intestine, displacing cholesterol so it cannot be absorbed.
-
Excretion: The unabsorbed cholesterol passes through the body and is eliminated as waste.
-
LDL Reduction: Consuming 1.5 to 3 grams of plant sterols daily can lower LDL cholesterol by 7% to 12% within two to three weeks without significantly affecting HDL (“good”) cholesterol.
Fortified Foods & Supplements To reach therapeutic doses (2 g/day) for cholesterol management, fortified options or supplements are often used:
-
Fortified Foods: Margarines/spreads, orange juice, milk, and yogurts explicitly labeled with added plant sterols or stanols.
-
Supplements: Available in softgels, gummies, or chews, typically taken alongside meals containing fat to maximize effectiveness.

How food allergies can affect mental health
- Stress and anxiety
- People with serious food allergies may experience ongoing worry about accidental exposure, especially if reactions can be life-threatening.
- This can lead to increased anxiety, hypervigilance, and fear around eating, traveling, social events, or dining out.
- Social isolation
- Food allergies can make school, work, parties, restaurants, and family gatherings more challenging.
- Feeling different or excluded may contribute to loneliness, low mood, or reduced quality of life.

Considerations
-
Fat-Soluble Vitamin Absorption: High intake can slightly lower the absorption of fat-soluble vitamins, particularly beta-carotene. Eating a diet rich in colorful fruits and vegetables easily offsets this effect.
-
Phytosterolemia: A rare genetic condition where individuals absorb excessive amounts of plant sterols; people with this condition should avoid supplements.
