What food has no carbs at all?

 While there are no foods technically with zero carbs, there are several options with extremely low carb content that can be considered virtually carb-free for most dietary purposes. Here are some examples:

Animal Products:

• Meat and Poultry: Chicken, beef, pork, lamb, turkey, venison, etc. contain negligible amounts of carbs.
• Seafood: Fish like salmon, tuna, cod, shrimp, and sardines are virtually carb-free.
• Eggs: Whole eggs are practically carb-free, with less than 1 gram per egg.
• Cheese: Many hard cheeses like cheddar, Parmesan, and mozzarella have minimal carbs, typically under 1 gram per ounce.

Fats and Oils:

• Cooking Oils: Olive oil, avocado oil, coconut oil, and butter are essentially carb-free.
• Nuts and Seeds: Although not completely carb-free, raw nuts and seeds like almonds, walnuts, chia seeds, and pumpkin seeds have very low carb counts, typically between 2-5 grams per ounce.

Non-Starchy Vegetables:

• Leafy Greens: Spinach, kale, arugula, and romaine lettuce are extremely low in carbs, usually under 1 gram per cup.
• Cruciferous Vegetables: Broccoli, cauliflower, Brussels sprouts, and cabbage are all low in carbs, with around 3-5 grams per cup.
• Bell Peppers: Different colors of bell peppers have very low carb content, typically 3-5 grams per medium pepper.
• Mushrooms: Most varieties of mushrooms, like white button, portobello, and cremini, are carb-free or have negligible amounts.

Remember, "net carbs" are sometimes considered when discussing low-carb diets. This refers to the total carbohydrates minus the fiber content. Therefore, some foods with slightly higher total carbs might still be considered low-carb due to their high fiber content (like berries or avocados).

It's also important to note that individual needs and dietary goals can vary. While these foods are generally considered low-carb, it's always best to consult a healthcare professional or registered dietitian for personalized dietary advice.
