Humans really are fat heads. About sixty percent of the human brain is fat. To maintain proper brain health, you need to get adequate fat from your diet. But, not just any fat will do. Some fats damage the brain. The Standard American Diet (SAD) high in trans and hydrogenated fats worsens inflammation in the body, and this inflammation can damage delicate brain tissues. These unhealthy fats are found in fried foods, shortening, lard, margarine, baked goods, and processed and prepared foods.
Healthy fats help keep the lining of brain cells flexible so that memory and other brain messages can pass easily between cells. Both Omega-6 and Omega-3 fats are important to brain health and should be eaten in a one-to-one or two-to-one ratio to each other. However, the average North American eats these foods in a twenty-to-one to a fifty-to-one ratio, causing a huge imbalance and resulting Omega-3 deficiency. In this ratio, Omega-6 fats can cause or worsen inflammation, for which there is insufficient Omega-3 fats to keep inflammation under control. The typical diet, if it contains any healthy essential fatty acids, usually includes fats found in meat and poultry, or occasionally from nuts and seeds. Most of these fats are Omega-6 fatty acids.
Omega-6 fatty acids are found in the highest concentrations in corn, sunflower, and safflower oils. But, you are more than what you eat. I read somewhere that “you are what you eat eats.” So that means if you eat a diet with meat or poultry that was fed corn, or other grains high in Omega-6s, you’re getting lots of Omega-6s indirectly.
Fish that contain high amounts of this Omega-3 fatty acid include mackerel, sardines, albacore tuna, salmon, lake trout, and herring. But be aware, some of these fish have become contaminated with mercury and, as you just learned in chapter two, some research links mercury to the development of Alzheimer’s disease. So, it is important to avoid fish that consistently shows up high on the mercury radar, including predatory fish like swordfish and shark, as well as sea bass, northern pike, tuna, walleye, and largemouth bass. Salmon raised in fish farms also frequently shows up with high amounts of mercury, not to mention that farmed salmon often contains antibiotic residues and lower levels of the important Omega-3 fatty acids.

【本報訊】糖尿病是本港常見慢性疾病,約 70萬人患病。一項大型國際研究發現,糖尿病患者會較其他健康人士短命 6年,出現併發心臟病或中風而死亡的風險更提高一倍。香港專科醫生學會建議市民及早檢查預防患病,患者更應盡力控制血糖指數減低併發症風險。
一項國際大型研究分析逾 100宗研究約 82萬,並跟進約 13年時間。結果發現,糖尿患者會較沒有患病人早死,若一名 50歲患者,會較同齡沒有糖尿的人士短命 6年;死於併發心臟病或中風風險更高一倍以上。此外,糖尿病人死於癌病的風險,也較常人提高 25%,另也會提升患腎病、肝病及感染的機率。
香港專科醫生學會會長盧國榮醫生指,根據國際糖尿聯會統計,全球每年約有 400萬人死於糖尿併發症,即平均每 8秒便有一人死於該病。他建議糖尿病人應控制飲食,例如糖化血紅素應維持在 7%以下,因為該指數每上升 1%,死亡風險便相應增加 21%。
學會副會長周振中醫生稱,現時洗腎新症中有四成都與糖尿病惡化所致,證明該病對身體各器官和部位影響甚大。他又稱,每年的截肢個案中,撇除因交通或工業意外所致的個案,餘下約五成截肢手術都是因糖尿病惡化而要截肢,即估計每年有 200隻腳因糖尿病惡化而被切除。
