And peanut butter, a staple of the American diet, especially for children, goes rancid, as it contains hydrogenated rapeseed, cottonseed and/or soybean oil, all of which are unstable and become rancid over time, often before peanut butter is even purchased by the consumer. Biotic Balance Probiotic Review

Experts tell us that the main problem with most of these oils is that they are way too high in Omega-6 polyunsaturated fatty acids. These oils were never available to humans until the 20th century and the ratio in the Western diet has shifted drastically, all the way up to 16:1. When the Omega-6:Omega-3 ratio shifts too high in favor of Omega-6, bad things start to happen in the body. The excess Omega-6 fatty acids build up in our cell membranes and contribute to inflammation, which is an underlying factor in some of the most common Western diseases, including cardiovascular disease, cancer, diabetes, arthritis, alzheimer's and many others.

While both Omega-3 and Omega-6 fatty acids are so-called essential fatty acids, the methods used in processing these oils for human consumption involves a harsh extraction process that can include bleaching, deodorizing and using the highly toxic solvent hexane. These are oils that are extracted from seeds like soybean, cottonseed, sunflower and the elusive "canola" source. The 3 main oil pressing techniques which most companies use to produce all these "healthy" oils are: hydraulic press, traditional "cold-expeller" pressing and solvent-extraction. All of these processing procedures compromise the nutritional value of the seeds, and, along with the use of chemicals to extract the oils, they also use heat, friction and oxidation, which damage the nutrients further. These oils have made their way to all sorts of processed foods, including salad dressings, imitation butters, mayonnaise, baked goods and more.
