Understanding Seed Oils: Impact on Health and How to Avoid Them
Learn about seed oils in restaurant foods, their potential health effects, and how Flykitt helps you identify and avoid them.
The Truth About Seed Oils
Understanding industrial seed oils and their impact on inflammation and health
What Are Seed Oils?
Seed oils (also called vegetable oils) are oils extracted from seeds like soybean, corn, cottonseed, canola, and safflower. Unlike traditional fats that have been consumed for thousands of years, industrial seed oils are relatively new to human diets, only becoming widespread in the 20th century.
These oils are typically highly processed using high heat, pressure, and chemical solvents to extract the oil from seeds that wouldn't naturally yield oil through traditional pressing methods. The resulting products are high in omega-6 polyunsaturated fatty acids and often undergo additional industrial processes like bleaching, deodorizing, and hydrogenation.
Common Seed Oils in Restaurant Foods
Why Consider Avoiding Seed Oils?
Research suggests several potential concerns with regular consumption of industrial seed oils:
1. Omega-6 to Omega-3 Imbalance: Seed oils are very high in omega-6 fatty acids. While omega-6 is essential, the modern diet often contains far too much omega-6 and too little omega-3, potentially contributing to chronic inflammation.
2. Oxidative Stability Issues: Polyunsaturated fats in seed oils are highly susceptible to oxidation when exposed to heat, light, and air. This oxidation creates harmful compounds that may contribute to inflammation and cellular damage.
3. Processing Concerns: The multi-step industrial process used to create seed oils involves high heat and chemical solvents that may create harmful byproducts and strip away naturally occurring nutrients.
4. Trans Fat Risk: Some seed oils are partially hydrogenated to increase shelf life and stability, creating trans fats which are strongly linked to heart disease and other health problems.
Many health experts now recommend limiting seed oil consumption in favor of more traditional fats like olive oil, avocado oil, butter, and coconut oil, which have longer historical use and different fatty acid profiles.
Seed Oil Prevalence in Restaurant Foods
Seed oils are extremely common in restaurant cooking. Here's where you're most likely to encounter them:
Where Seed Oils Hide in Restaurant Meals
Cooking Methods
Deep frying, pan frying, sautéing, and stir frying all typically use seed oils in restaurants due to their lower cost and high smoke point. Even foods that appear grilled may be brushed with seed oils during cooking.
Dressings & Sauces
Most commercial salad dressings, mayonnaise, aioli, and creamy sauces use soybean or canola oil as their base. Even vinaigrettes in restaurants often use a blend of olive oil and cheaper seed oils.
Breads & Baked Goods
Bread, buns, tortillas, and pastries usually contain seed oils as dough conditioners or to extend shelf life. Many are also brushed with oils before baking.
Marinades & Glazes
Meat and vegetable marinades almost always include seed oils, often combined with sugars and spices to create signature flavors.
How Flykitt Analyzes Seed Oil Content
Flykitt's AI-powered system conducts a detailed analysis of seed oil content in every restaurant menu item. We look at:
1. Presence: We identify whether seed oils are likely to be present based on the dish description, cooking methods, and restaurant type.
2. Amount: We estimate if the seed oil content is trace, small, medium, or large based on preparation methods and dish components.
3. Avoidability: Crucially, we determine whether the seed oils are 'removable' (like requesting dressing on the side) or 'unremovable' (like oils used for deep frying).
4. Source: We identify the specific sources of seed oils, like 'frying oil,' 'dressing,' or 'sauce base.'
This comprehensive approach gives you the information you need to make informed choices about seed oil consumption when dining out.

Practical Tips for Avoiding Seed Oils When Dining Out
Choosing Restaurants Wisely
Restaurant Types More Likely to Use Quality Oils:
- Farm-to-table establishments that emphasize local, quality ingredients
- Higher-end restaurants with chef-driven menus
- Mediterranean restaurants (often use olive oil)
- Health-focused establishments that explicitly advertise clean cooking oils
Questions to Ask When Researching Restaurants:
- "What type of oil do you use for cooking?"
- "Do you offer dishes cooked in butter or olive oil instead of vegetable oil?"
- "Can dishes be prepared without using seed oils?"
How Flykitt Helps:
Use Flykitt to filter restaurants in your area that tend to have menu items with lower seed oil content. Our ratings take into account the typical oil usage patterns of different cuisines and restaurant types.
Navigating Restaurant Menus
Menu Terms That Suggest Lower Seed Oil Content:
- "Grilled" (especially dry grilled)
- "Roasted"
- "Baked" (without breading)
- "Steamed"
- "Poached"
- Dishes specifically mentioning olive oil, butter, or avocado oil
Menu Red Flags (Likely High Seed Oil Content):
- "Deep-fried", "Crispy", "Battered"
- "Pan-fried" (unless specified with butter or olive oil)
- "Creamy" sauces and dressings
- "Stir-fried" (typically uses seed oils in most restaurants)
How Flykitt Helps:
Flykitt analyzes menu items to identify those with lower seed oil content and highlights potential modifications to reduce seed oil exposure.
Smart Order Modifications
Request These Substitutions:
- Ask for dressing on the side (or olive oil and vinegar instead)
- Request butter instead of margarine
- Ask for dry grilling or cooking in olive oil/butter if available
- Skip the sauce or request it on the side
- Ask for steamed vegetables with butter instead of sautéed vegetables
Specific Phrases to Use:
- "I have a dietary restriction - can you prepare this without vegetable oil?"
- "Could you use butter or olive oil instead of vegetable oil for cooking?"
- "I'd prefer my salmon simply grilled without oil, if possible."
- "Could I get a side of olive oil instead of the regular dressing?"
How Flykitt Helps:
Flykitt recommends specific modifications for each dish to help you avoid or minimize seed oil exposure while preserving the dish's essence.
Strategic Meal Composition
Focus on These Food Categories:
- Simple grilled proteins (steak, chicken, fish)
- Fresh vegetables (ideally steamed or raw)
- Fresh fruits
- Eggs (ideally poached or boiled to avoid cooking oils)
- Simple salads with olive oil and vinegar dressing
Create Balanced Meals By:
- Ordering a simple protein entrée
- Adding a side of steamed or roasted vegetables
- Requesting olive oil and vinegar for any salad
- Skipping the bread basket (often contains seed oils)
- Choosing fresh fruit for dessert instead of baked goods
How Flykitt Helps:
Flykitt's analysis shows you the seed oil status of every component of your meal, allowing you to compose a balanced plate while minimizing seed oil exposure.
