Fat is Not the Enemy: A New Perspective On The Pros And Cons Of Oily Foods
Your body is supposed to be full of fat, about 18 percent if you’re a man and 28 percent if you’re a woman. Your brain must be particularly fatty. At least 60 percent of it should be composed of very particular fatty substances that have to be constantly replaced. The brain and body (including the heart!) require high quality fats to perform very complex physical-and-mental-health-related duties. To feel your best, you need to feed regularly on the finest fatty foods. If you’re wondering how any fatty foods could actually be good for anything, you’re about to get a nutritional villain adjustment, so hold on to your hat.
To start with, think of the positive words associated with fat: rich, shining soft, cuddly… In ancient times, fat was associated with joy, wealth, and even sanctity. Healthy fats are essential to life!
By 2006, even the fat phobic American Heart Association became so concerned about our fat needs that it dropped its restrictive 30 percent fat recommendation altogether!1 Instead it urged us to eat more fatty fish and toughened its stand against high carb foods. Why? It caved under the overwhelming evidence. It recognized that happier and healthier cultures all over the world had a higher intake of certain fats than the AHA had recommended for us in the U.S. and that low fat had led to neither lowered rates of heart disease nor lower weights. (Quite the reverse, in fact.) It also recognized that the “low fat” sweets and starchy carbohydrates that we’d been eating in this country in our efforts to cut fat had led to record rates of a new health and mood scourge-diabetes. The incidence of diabetes had doubled in the past 30 years, and one in three children had become victims of this deadly epidemic fueled by carbs, not fats.
HEALTHY FAT SURPRISE: Saturated Fats
Now for some real fun. Think of the fatty foods you’d love to eat if you thought they wouldn’t kill you or cause unneeded weight gain. When I tell my clients that butter and sour cream are safe and healthful, they beam incredulously as if a loved one were being returned from the dead. Little do they know that they may be the loved one in question. We have been “good” for 30 years. We’ve cut down hard on what we thought were “bad” fats, meanwhile stocking up on “safe” vegetable oils and hydrogenated fats, but the results have been terrible. Heart disease has continued to escalate and cancer and diabetes have become epidemic.
So, now are you ready for some good news about cream cheese, whole fat yogurt, chicken skin, and coconut milk? I know that this is going to be hard for you to swallow. Part of it is the term Saturated Fats. Let me give it a new spin. Let’s call it SAT: short for SATISFYING. All saturated fats are complete in their molecular structure, unlike the omega-6 and omega-3 polyUNsaturated fat molecules that look like combs with broken teeth. Their density gives SATs their undisputed stability. It’s why they don’t get rancid, something we’ve always known.
Could these disreputable fats actually be healthful? Yes! The same study that convicted the trans fats in margarine and shortening of murder by heart disease, also pardoned the saturated fats. “There was no association between intake of saturated fat and the risk of coronary death.”2 The scientific literature is loaded with this exonerating evidence. In fact, SATs are the preferred energy source for your heart because they burn at such a reliable pace, much steadier and longer than carbs do. Many studies even confirm that saturated fats can also protect you from stroke3.
One of the most extraordinary benefits provided by these creamy fats we’ve been avoiding all these years is that they protect our tissues from rancidity, especially the precious, but fragile, omega-3 fats in our brains and arteries. SATs also reduce the negative effects of excess omega-6 fat; and they can actually lower levels of the most potentially damaging omega-6 fat, arachidonic acid.4 5 (More on the dangers of high omega-6 vegetable fats, like soy and corn oil, later.)
Four recent studies, three on type II diabetics and one on mildly obese men and women, used a high saturated fat, low carb diet. Their results: all showed improvement in cholesterol levels, weight, and insulin levels.6 7 But these studies are really just confirming common sense. Most people all over the world have always consumed lots of saturated fat and thrived physically and emotionally. We did, too. In 1909 we consumed about 26 pounds of saturated fat per year and nine pounds of omega-6 fats (on top of what was in eggs, meat, etc.). In 1998 we consumed less than nine pounds of saturated fat and 66 pounds of omega-6 fat! SATs are not our problem. The omega-6’s vegetable oils are the problem.8
You can safely cook with SATs, because at a heat that would toxify any vegetable oil, the sturdy SATs hold up. SATs are also great for energy, converting slowly and steadily into cellular fuel as needed. This keeps your blood sugar levels rock solid, which means your mood and vitality level stay more solid, too! Plus your craving for carbs drops off. Saturated fat is a wonderful, steady, stress-relieving energy fuel that athletes use to perform better.
Our obesity epidemic is partly due to SAT deprivation. Without SATs, food is not satisfying, so we tend to eat too much of the carbs and vegetable oils that we do allow ourselves. Refined carbs and the commonly used vegetable oils both increase unneeded weight as well as a myriad of health problems that I’ll discuss later.
Not only do we experience better endurance with saturated fat, but our immune systems are actually enhanced by it as well, in contrast to the immunity-lowering effects of low fat foods.9 Ghee (clarified butter), coconut and palm oils are the fats traditionally used for cooking all over the world by people whose weight and freedom from degenerative diseases are much better than ours are!
The crucial vitamins A, D, and E cannot be absorbed into our bodies without their carrier saturated fats. Nor can calcium! For example, spinach has lots of calcium, which is not absorbed well unless it’s eaten with butter (or olive oil, which also contains some SAT). Same principle with collard greens and bacon fat.
Now let’s take a look at my personal favorite SAT. Butter is so packed nutritionally, with its 10 vitamins, 10 minerals, 18 amino acids, and 11 kinds of fat, that it’s hard to know where to begin. It’s tremendously high in vitamin A, which it helps deliver to your eyes (night vision is absolutely dependent on an adequate vitamin A supply). Vitamin A regulates the female sex hormone progesterone, too, providing many mood as well as fertility and other benefits. “A” also stands for Anti-tumor, and saturated fats like butter assist vitamin A absorption and uptake in this life-preserving function, but too many Omega-6 fats can block it.10 Then there’s butter’s butyrate, the fastest burning of all fats. This very special fatty acid is used extensively in your brain. For one thing it serves as a base for making GABA, your natural Valium (GABA stands for gamma amino butyric acid.) It can also protect you from colon cancer and is used as a medicine in pre-cancerous colon problems to do just that.
SATs and Other Fats Fight Food Addiction
How did I lose my own fear of SAT fats? Through twenty years of working with people who had eating disorders. Our under- and overeaters have often had one thing in common. They avoid fats and love carbs. The anorectics still love their bagels, apples, or jellybeans, and the overeaters often avoid fat, too, to save their calories for pure-carb binges.
After years of trial and error, we developed some successful nutritional treatments. The first thing that worked was increasing protein, which helped stop everyone’s moodiness, overeating, and obsessiveness. We added lots of vegetables as the only carbohydrates allowed, and tried to keep fat levels low. At the same time we expected our clients to exercise regularly. But this low-fat and low-carb diet didn’t give them enough energy. It didn’t always lower the high cholesterol levels of some of our overeaters either. Because nuts and seeds were often binge foods, we couldn’t recommend them, so we tried a new food plan that ended up working like a charm. It was very simple: high protein, high vegetables, and high—mostly saturated—fat. No sweets (even fruit) or high-starch foods at all. The results: no cravings, high energy, sturdy blood sugar levels, satisfied with the food, mood fine, weight normalizing, and lowered cholesterol!
Cardiologist, Robert Atkins, M.D., reported the same thing and research on The Atkins Diet—even higher in fat and lower in carbs than our clinic’s diet—has confirmed our experience.11
When the brain and body receive the specific fats they’ve been starved of, they quit sending out desperate calls for fries and chips. If adding saturated fats alone does not stop fat cravings, we add supplements of omega-3 (EPA and DHA) fat, GLA, and the fat-soluble vitamins A, E, and D. (We test vitamin D levels first.)
What Is Carb-Fat?
How is it that too many carbohydrates can cause such an increase in body fat? Because when there are too many carbs, they have to be converted into stored fat in the muscle. From there they can be reconverted into carbs for the muscle to burn as fuel if we exercise regularly and vigorously. But we’re more sedentary now than ever in history, and there is simply so much carb being converted into body fat that even people who work out daily can’t burn off the overload. Worse, sweets and starches are converted into thick substances called triglycerides to be carried through the bloodstream to the muscles. High-triglyceride levels pose more cardiovascular health risks.
The Good News About Cholesterol
Cholesterol is not a fat, but I could go on at the same length about the health and mood benefits of cholesterol as I just have about the benefits of saturated fat. Let me just say that a cholesterol level between 180 and 260 seems to be ideal. With levels above or below that range, we can have more health troubles, but more of the trouble than you think comes with cholesterol levels that are too low, rather than too high. A 40-year study of 4,000 people in Hawaii found that “the earlier that patients start to have lower cholesterol concentrations, the greater the risk of death.”13 Many other studies concur.
Surprisingly, cholesterol is one of the most valuable nutrients there is for stress-coping, since it is the substance that’s used by our adrenal glands to make our stress-coping hormones. Our sex hormones are also made from it. If you’ve been avoiding it stringently, you may have innocently compounded all kinds of problems.
Low cholesterol is firmly associated with depression, anxiety, irritability, violence, suicide, and insomnia partly because, in the brain it is essential for our natural antidepressant serotonin production.14 Autistic children are typically very low in cholesterol and are actually being treated successfully—with cholesterol!15 16 A huge amount of the brain, about 25 percent of it, is cholesterol. Cholesterol is (surprise!) an antioxidant that actually protects our tissues, including our brain tissues and arteries. Cholesterol is not a fat; it’s an alcohol that we can make from many foods. Cows obviously make it from grass. Avoiding fat, therefore, is not a particularly effective cholesterol-lowering tactic, even if you are someone with truly high cholesterol. Books that will tell you much more of the fascinating true cholesterol story are The Cholesterol Myths: Exposing the Fallacy That Saturated Fat and Cholesterol Cause Heart Disease by Uffe Ravnskov, M.D., and Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health by Gary Taubes.
Now let’s talk about my second favorite SAT, the delectable one that makes so many of my clients smile when I recommend it: coconut milk. Do you enjoy this food in Thai cooking? I defy you to find more beautiful or cheery people than the Thai. They, like so many equally healthy peoples in southern climates eat lots of this saturated fat. Coconut fat contains powerful antiviral and anti-fungal fats and is a bit more stable even than butter, too, as it is a little more saturated (think satisfying, satiating, and rancidity resistant.) That’s why the milk and oil of the coconut is so safe as well as yummy to cook with.
The Omega-3 Fats
This health-and-mood-promoting-fat belongs in special places like your brain and your arteries. We don’t need lots of O-3, but getting enough is essential to life. Every time you consume this extraordinary oil, your brain gets first dibs, because no other fats can do as good a job. As I’ll explain later, the “other” essential fats, omega-6s, may be your brain and heart’s worst enemies and the cause of some of your worst mood and health problems. For example, the rate of depression between individuals correlates precisely with the ratio of omega-3 fats to omega-6 fats in their brain. The more omega-3, the better the mood and heart-health; the more omega-6, the worse your mood and heart-health. In the U.S., we are very low in our omega-3s. If we add more omega-3, we can instantly raise a potent chemical called dopamine by 40 percent!17 That translates to significantly enhanced mental and physical alertness and energy.
It turns out that, among other things, omega-3 is an MAO inhibitor, meaning it paralyzes the MAO enzymes that destroy mood-boosting brain neurotransmitters like dopamine.18 Believe it or not, these fats can even be over-stimulating to some people. If you find yourself waking up bright and alert at 4 a.m. after too much omega-3 supplements, you’ll have to cut back.
And, as if all this weren’t enough, after you’ve been eating more omega-3s for a few months, and your brain’s needs are met, the omega-3s will move into the linings of your arteries and remove any plaque that has built up in your body’s botched efforts to repair its linings without enough of its preferred omega-3! The many studies on omega-3’s positive impact on artery health and heart disease are heartening!19 20 21 How much do you need and where can you get the omega-3? Omega-3 fat comes in two forms: a ready-for-brain-and-artery-use form found in fish, and a cruder form found in flax seeds and some other foods in very small amounts. The latter is a shorter form of omega-3, ALA (Alpha Linolenic Acid), that has to be worked over by certain enzymes that two thirds of us don’t have, and that decline with age. For all of us, ALA helps the body expel the excessive omega-6, but can’t be reliably used to form the long chains that our brains need. These brain chains should wrap around in our brain cells, forming very special membranes that can transmit billions of molecular messages instantly and accurately. These fatty chains are called docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
Fish fat is full of EPA and DHA, the ultimate omega-3 fats. Fish like sole contain some, and there’s a little bit of the shorter ALA (flax-like) version in almost all fatty foods, both animal and vegetable. But by far the best sources of the omega-3 fats are wild salmon, sardines, herring, anchovies, and mackerel. They have about three times more omega-3 than other fish and 5 times more than flax seed oil. Their good-health fat is especially concentrated in and under the skin. (So enjoy this crisp and delicious part of your fish.) These fish are also likely to contain much less toxic mercury than larger fish such as tuna and swordfish.
To get enough vital omega-3 fats, you’ll need to eat fish more often, as your ancestors did. For example, the Japanese still eat two and a half pounds of fish weekly, and their depression rates have been historically nil, as have their heart disease rates. But when was the last time you ate fish five times a week? That’s how much you might need to eat, at least for awhile, to get enough omega-3s to elevate your mood and energy and counterbalance the years of omega-6 build-up.
The recommendations regarding the ideal ratio between the two fats ranges from 1:1 to 4:1, omega-6 to omega-3, but in the U.S. the ratio is now over 25:1.22 The vital ratio has begun to change in Japan now, too. Imitating their friends in the U.S., the Japanese have been eating too much of the omega-6 vegetable oils and trans fats, and depression, heart disease, and cancer rates are increasing dramatically as a result. In fact, the Japanese scientific community formally announced in 1997 that the high omega-6 vegetable oils are almost solely responsible for their new health problems and are “unfit for human consumption.”23
In the U.S. we used to get quite a bit of omega-3 from milk, meat, and chicken as well as fish, but now most of these animals are fed grain high in omega-6, rather than grass, hay, or bugs with higher omega-3 content. Grass-fed beef is coming back, though, and it’s 14 times lower in omega-6 fats.
According to the FDA, we can safely eat 2.2 pounds of fish a week (preferably not higher omega-6 farmed fish). That’s about five or six servings weekly. Unfortunately, because of the recent acknowledgements of high amounts of mercury and other pollutants in many fish, I would not recommend fish more than two or three times a week, and I would recommend great care in choosing your fish, especially if you are pregnant. Note: Remember, don’t cook that fish in high omega-6 oil, and don’t dress it with mayo or tartar sauce, unless made yourself with olive oil. Fortunately, we can take contaminant-free, molecularly-distilled fish oil supplements to help fill our omega-3 quotas. Your Basic Supplement Suggestions include about two grams a day of fish oil (combined DHA and EPA). That’s the equivalent of one-quarter pound of salmon or sardines a day. If you also eat fish at least twice a week you’ll make your omega-3 quota nicely. (And get some excellent, tasty, quick-to-prepare protein, to boot!)
Note: Flax oil is only helpful in the brain and arteries for one third of us, at best. The rest of us can’t convert its crude ALA omega-3 fat into DHA and EPA. Even those of us who can convert the ALA in flax need to use five times more of it than of the fish oil to get equivalent potency. This much flax oil would be excessive because flax also contains significant amounts of omega-6 fats which pose problems since we’re already eating too much of it.
The Omega-9 Fats
The oil most endowed with lovely omega-9 fat is olive oil. Just being the only oil that you can still safely use on your salads, now that I’ve demoted most of the high-omega-6 competition, should qualify olive oil (extra virgin olive oil to be precise) as a major mood and health champion. Olive oil contains very little of anything but omega-9 fats, which are almost as stable as saturated fats. It also contains a little saturated fat, and almost no omega-6 fatty acids, so it doesn’t get rancid easily. It keeps well in a cool dark place, even after it’s been opened. Although it’s low in the omega-3s, the omega-9s in olive oil are very supportive of the omega-3s, and they can specifically help promote serotonin’s antidepressant and anti-carb craving activities in your brain.24 25

Nuts and Seeds
The nuts and seeds highest in omega-9 (but low in omega-6) are cashews and macadamia nuts and high oleic (i.e., high omega-9) sunflower and safflower oils. Note: Frying destroys omega-9 fats, but sautéing with them doesn’t. Peanuts, almonds, filberts, hickory nuts, and pistachios are high in omega-9, too, and somewhat lower in omega-6 than other nuts and seeds. (Eat them in small servings, though, because they do still contain considerable omega-6s.)
