In our diet we lack one family of oils called omega-3 fatty acids. These are found in walnuts and flaxseeds (linseeds). It is important to regularly incorporate these seeds in your diet. Walnut and flaxseed oils are very prone to rancidity because the omega-3 fatty acids they contain are very fragile and can easily suffer from oxidation. Buy from a reputable manufacturer, keep these oils in the refrigerator and use within six weeks of opening.

There are quite a lot of commonly eaten nuts and seeds that type Bs need to avoid, mainly because of the agglutinating lectins they contain. Avoid peanuts, cashews, pine nuts, pistachios, pumpkin seeds, hazelnuts, sesame seeds and sunflower seeds. Avoid all oils made with these nuts and seeds including canola, soy and corn. You can enjoy walnuts, linseeds, almonds, brazil nuts, pecans and macadamia nuts. The best cooking oil is olive oil and for salads choose flaxseed, walnut and olive oil.

Fats and Oils

Nuts and seeds contain some essential fats, and because these fatty acids are “essential” a deficiency can greatly compromise our health. Up until about 50 years ago nuts and seeds were cold pressed in local mills, where people would regularly buy a fresh supply. Today, refined oils are the norm. These may last a long time in the bottle but they have little of the health-giving qualities of cold pressed oils and can have a detrimental effect on health.

It would take many, many pages to write about all the health benefits of fats and oils. Suffice it to say that every cell in the body, in order to function properly, needs the right fatty acids. And given that our cells are what make up our tissues, our organs and ultimately our bodies, should we not be giving them the best possible sustenance? If at all possible avoid industry-made oils and use the best quality cold pressed oils you can find – buy from a reputable manufacturer, keep the oil in the refrigerator and use within six weeks of opening. France is walnut country and cold pressed walnut oil can be easily found. I regularly recommend eating walnuts and using walnut oil in salads. Many people use olive oil in salads but it does not contain essential fatty acids.
