Here’s a low carb food list and the buying techniques I use which will help you buy ketogenic foods that are clean, whole and offer the best nutrition.
Since the majority of calories on a ketogenic diet will come from dietary fats, choices should be made with digestive tolerance in mind. Most people cannot tolerate eating a large amount of vegetable oil, mayonnaise or even olive oil over time. And this is a good thing, since vegetable oils are high in polyunsaturated Omega-6 fatty acids.
The Omega-6 fatty acids (found in nut oils, margarines, soybean oil, sunflower oil, safflower oil, corn oil, and canola oil) should be limited due to the inflammatory effect they trigger within the body. Most nuts (with the exceptions of macadamias and walnuts) are high in Omega 6 fatty acids as well, so go easy on them). Your intake of polyunsaturated fats should be balanced between Omega 6 and Omega 3 types. Eating wild salmon, tuna and shellfish will provide balancing Omega 3 fatty acids and are important part of a low carb food list. If you don't like seafood, then consider taking small amounts of a fish or krill oil supplement.
Saturated and monounsaturated fats such as butter, macadamia nuts, coconut oil, avocado and egg yolks are tolerated more easily by most people, and since they are chemically stable, they are less inflammatory. Fats and oils can be combined in sauces, dressings, and other additions to basic meals. Over time, it will become a habit to add a source of fat to each meal.
Avoid hydrogenated fats such as margarine to minimize trans fats intake. If you use vegetable oils (olive, canola, sunflower, safflower, soybean, flaxseed and sesame oils) choose "cold pressed." Keep cold pressed oils like almond and flaxseed refrigerated to avoid rancidity. Avoid heating vegetable oils. Use clean non-hydrogenated lard, beef tallow, coconut oil, ghee and olive oil for frying, since they have high smoke points.
Fattier cuts of meat are better because they contain less protein and well, more fat. Choose organic or grass fed animal foods and organic eggs if possible to minimize bacteria, antibiotic and steroid hormone intake. Websites such as www.eatwild.com or www.localharvest.org can point you to local sources of clean, grass fed meats and poultry. These clean proteins are the best choices for a low carb food list.
Most non-starchy vegetables are low in carbs. Choose organic vegetables or grow your own to avoid pesticide residues. Avoid the starchy vegetables such as corn, peas, potatoes, sweet potatoes, and most winter squash as they are much higher in carbs. Limit sweeter vegetables such as tomatoes, carrots, peppers, and summer squashes.
Any leafy green vegetable
Lettuces and salad greens (Arugula, Bok Choy, Boston lettuce, Chicory, Endive, Escarole, Fennel, Mache, Radicchio, Romaine, Sorrel.)
Onions (limited amounts, as they are higher in sugar)
Raw milk products are preferable; choose organic if raw products are not available.
Nuts and seeds are best soaked and roasted to remove anti-nutrients. Avoid peanuts as they are actually legumes.
Avoiding sweetened foods in general will help “reset” the taste buds. However, if there is a desire for something sweet, these are the recommended choices for sweeteners. Note that the powdered forms of most artificial sweeteners usually have maltodextrin, dextrose or some other sugar added, so liquid products are preferred.
*Some readers have objected to my recommending Splenda. If you have concerns about this, please note that I have done research in the medical literature and I have looked at the studies which have been offered on sucralose (Splenda).
I have yet to find a gold standard, clinically controlled human study which shows conclusively that sucralose causes human health issues. I don't like to propagate misinformation so I wait until there are definitive studies of negative effects before I condemn a product. In my opinion, eating sugar, honey and other nutritive sweeteners has negative blood sugar effects which far surpass those which might be associated with using a small amount of Splenda, or any other non-nutritive sweetener.
Having said that, I will also say that I offer information on this low carb food list about Splenda, just as I do on the other sugar substitutes, because everyone is different. Some people are not bothered by Splenda, while others are. It's the same for sugar alcohols and other sweeteners such as inulin and chicory root. I try to offer both pros and cons for each sweetener, with the idea that readers will use the product that suits them best. See my artificial sweeteners page for more information.
Spices do have carbs, so be sure to count them if they are added to meals made using this low carb food list. Commercial spice mixes like steak seasoning usually have added sugar. Sea salt is preferred over commercial salt, which is usually cut with some form of powdered dextrose.
Basil, Black pepper, Cayenne pepper, Chili pepper, dried, Cilantro/Coriander seeds, Cinnamon, ground, Cloves, Cumin seeds, Dill, Ginger, Mustard seeds, Oregano, Parsley, Peppermint, Rosemary, Sage, Thyme, and Turmeric.
These are great resources for how to prepare the items on this low carb food list.
