If you're having trouble tolerating foods, read on. If you just want to know what the fuss is about Paleo diets, there's a reading list at the bottom of the note.
For years, I suffered from unknown respiratory problems every winter. In 2008 I went to Morocco and came back with a sinus infection, went on antibiotics for 14 weeks, on and off, which is guaranteed to devastate your immune system and intestinal flora. That fall, I realized I had food allergies and sensitivities. I went back to Morocco for 6 weeks that winter, which, oddly enough, changed my life, maybe saved it. I HAD to find food I could eat, and there's almost no processed food there. Everything is fresh and seasonal. And if I could read food labels in French, well, surely I could feed myself in Canada!
The next year, my father developed cancer and died, my mother was diagnosed with dementia. I had to move back to my hometown to help her. This was highly stressful for both of us. My hometown is a good place to have unusual food needs, so I was able to find things I could eat there, but I was not motivated to cook, and food was not a source of pleasure. I've been an avid cook all my life, so this was a hard time. It was, at best, a holding pattern.
My mother died in 2011, and that year, I gained 40 pounds. Part of it was diet, I know. I'd started eating grains again, comfort food, and too much fruit and sugar. In healthy forms, but too much for my system.
I'd heard about Paleo before, but never looked at it in depth. When I did, I realized that this method of looking at food avoids all the foods that cause me problems. And the point of Paleo is not just to avoid foods known to cause problems for many people, but to enjoy the foods you CAN eat. It's not about deprivation, it's about seeing food as something that will make you whole and healthy. Food is medicine.
Above all, take control of what you eat.
There are several underlying concepts behind the Paleo diet concept, which is not a diet so much as a lifestyle. A primary one is that for more than a million years, human beings were hunter gatherers. Agriculture is a recent development in our history, and ten thousand years or less is not enough time for all humans to adapt completely to thriving on a diet of mostly grains and grain products. But more importantly, even if our ancestors ate grain, it was in a more natural form than the highly processed products we see in stores now. Stone ground whole wheat or sprouted rye is a very different substance than white flour. I'm not even going to talk about all of the refined starches and sugars we ingest. The single highest source of calories from carbs in the US is high-fructose corn syrup. Not wheat flour or corn or even sugar in a form you can see. It's in food you don't even know it's in, in forms you can't recognize, and it's so highly caloric, it's the biggest single source of calories we get from carbs today.
Similarly, modern milk products are nothing like whole fresh milk straight from the cow or goat. The more processed a product is, the less like real food it has become. Low fat milk products are full of carbs and sugars.
If you know anything about food allergies, you know that there are 8 or 9 known deadly food allergens: milk, eggs, soy, peanuts, wheat, seafood, sulfites, tree nuts and sesame. And guess what? Four or five of these are in pretty much every processed food sold in North America. Talk about a recipe for creating allergies, even in people who were only mildly sensitive!
There is a syndrome called "leaky gut," which is not accepted by some medical authorities but has the support of many scientists. Leaky gut happens when you eat foods that irritate your intestinal tract, go on antibiotics and destroy your normal intestinal flora, and some other problems. Your intestines, like your skin, are a primary barrier to toxins, allergens and irritants. Maintaining the integrity of your intestinal barriers is important to good health. You may not be aware of irritation; it may only affect you on a cellular level. In a simple form, think of it this way: the cells lining your intestines have several layers, and as these get irritated and inflamed, they swell away from one another and there will be tiny gaps between these cells. Entire particles can leak through the walls of your intestines into your blood stream, and when they do, they're targetted as invaders by your immune system. This may create more allergies or food sensitivities. It also leads to further inflammation, which may happen in parts of your body unrelated to your digestion. Auto-immune disorders such as hypothyroidism, inflammatory disorders like fibromyalgia or arthritis, even illnesses as seemingly unrelated as heart disease and diabetes may be triggered or made worse by eating foods that irritate your gut.
If you're finding you're becoming sensitive to more and more foods as time goes on, it may not be age or bad genes. It may be the food you're eating that's leading, in a roundabout way, to heightened sensitivities. You may not know which foods cause these reactions; a food reaction can take as long as 72 hours if it's not a direct allergic reaction, so you may not be able to trace cause and effect.
An allergy is a response of your immune system. This will rarely be an intestinal reaction, but hives, itching, swelling, headaches and anaphylactic shock. An intestinal response (nausea, vomiting, dairrhea, constipation) is an intolerance and rarely caused by an allergy as such. There are also food aversions, that you simply cannot get a food down without gagging. And there are sensitivities, which can take many forms. If the problem you have with a food can be treated with digestive enzymes, it's an intolerance, not an allergy.
If you have a problem with stomach acid, see a doctor to be sure you don't have damage to your esophagus caused by acid reflux. But the sensation of acid stomach can actually be caused by not enough acid in your stomach to digest your food properly, which can be caused by an imbalance in your system. This may be the result of recent food poisoning, antibiotics disturbing your intestinal flora, or just eating the wrong foods for a long time.
Practical Paleo (see below) gives some good, concise information about digestive problems and intestinal health.
None of this advice is meant to be a substitute for seeing your doctor or a good nutriitionist or naturopath. There are other factors to optimal health: get enough sleep (it's NOT for sissies!), reduce the stress in your life, find ways to focus on the positive. If you find yourself always cranky or sad or angry, talk to your doctor and see if you have a physical problem or a psychological problem that can be treated. Being in a negative state all the time is a serious health risk, to you and the people around you. Get some exercise, even if it's just a walk. Do something fun. Make stuff so you feel a sense of achievement. And eat good food.
Eating well is more than avoiding the bad stuff. It's about eating a variety of healthy foods that nourish your body, provide nutrients you need, and nourish the good bacteria we need in our systems to help our bodies do the work they do to support us.
One author I read recently said we started to see the onset of "diseases of civilisation" at the same time science began its reductionist way of looking at food, in terms of calories, carbohydrates, proteins and fats.
Heart attacks were unknown as recently as 200 years ago. Cancer was not a feature of life and dementia was uncommon. And this is not because people used to die too young to get this stuff and we live longer; we don't. The notion that people in the past died young is based on skewed statistics. Infant mortality was more common, and even a few people dying before their first birthday pulls the "average" lifespan of a population down quickly. Infection killed people, and accidents often spelled certain death. But the people who DID survive often had just as good a chance of living to a ripe old age as we do. And studies have shown that their teeth were better and their bones were stronger than ours are.
We don't know what the long-term effects of a diet of soda pop, skim milk, burgers, frozen pizzas and store-bought cookies will be. Elderly people alive today grew up on a very different diet than we eat now. I mean, who eats liver anymore, or makes soup from scratch?
The biggest single environmental factor in your health is what you eat. And it's one thing you CAN control.
Food should be about what tastes good, and what has been demonstrated, through millennia, to make people feel stronger and healthier. And if it can be local, fresh and seasonal, even better.
Most of the books below have commonalities. Practical Paleo is great for basic knowledge and a one-stop resource for science, nutrition, shopping tips and recipes. The best books for understanding the science are Deep Nutrition and Primal Body, Primal Mind. Well Fed has wonderful, practical tips for cooking from scratch even if you're living a hectic modern lifestyle. And great recipes from global cuisine!
Most of what's in these books I've read in other places, so this is not weird science. Why isn't your doctor telling you this stuff? Besides the oft-noted fact that most doctors get only a week of nutrition in medical school, doctors also are trained to TREAT health problems, in a practical applied-science way. They are not necessarily trained to track a problem to its root cause. They don't have time to do that in 10 or 15 minutes with each patient.
Our medical system is dominated by a corporate mentality, and by corporations that manufacture drugs. I'm not a fan of conspiracy theories and I'm not an anti-corporate crank. I'm sure most doctors are sincerely interested in making people well. However, when I read that pharmaceutical companies WANT to sell drugs to healthy people, that there's money to be made in promoting illness and no money to be made in making people healthy enough not to need drugs, the penny dropped. We need to take control of what we eat, and we need to stop focussing on poor health and what can go wrong, and focus on good health and what we can do RIGHT!
Even when I was living in my old hometown the past 3 years, living with a lot of stress, I had one cold. Just one. Clearly I was doing something right. I'd like to carry on along that same track!
My husband and I used to save bones and make soup stock. He had clear signs of arthritis, yet no degeneration or pain. After a doctor commented on this, we realized the soup made from scratch was likely why. Bone broth is a cornerstone of the Paleo lifestyle. It puts back into our bodies many of the nutrients we need to keep our bones, connective tissues and even blood vessels strong and supple.
If you tolerate dairy, eat whole milk. Eat real yogurt and real cheese. Don't eat processed dairy, which is hardly even food anymore. "Low fat" foods are full of sugar and other weird stuff. Don't let them in your house. Eat liver once in a while. Eat lots of vegetables and some fruit. Buy local organic produce in season. Use your freezer. Make food from scratch. If you think you're too busy, read Well Fed, which has some fabulous tips on how to eat nutritious delicious food even if you're busy.
There are other principles, but those are the basics. This is not weird food. Nobody says you need to eat a mammoth or crunch down bugs or anything.
Above all, don't take my word for it. Read some of these books. Google "paleo" and see what comes up. There are a few people making money from this, but on the whole, nobody is going to get insanely wealthy from telling you to make your own soup stock and sauerkraut, and buy produce from your local farmer's market.
Ignore the science and this is really just Grandma's kitchen. My grandmother lived to be 97. If you left her table feeling full, it was from too much chicken or roast beef with homemade gravy and Yorkshire pudding, not because you made yourself sick with too many tortilla chips or Dingdongs. Okay, maybe not everybody's grandma cooked like that. Both of my grandmothers were good cooks, they had gardens and grew fruit and raised chickens. They bought beef from the farmer down the road and made soup from bones and scraps. Those Grandma meals made people strong and healthy.
Since I've been shopping for food the Paleo way, I'm bringing home bags and bags of groceries, but because it's all whole food, it costs me $15-25 a bag. Thirty years ago, I figured $20 a bag was good shopping, so this is not costing me a fortune. Seeking out grass-fed or free-range meat and eggs will cost more, high quality produce can cost more, but there are ways of reducing these costs: go in on buying a whole cow or pig with friends, join a CSA to get organic produce regularly, shop at a farmer's market, buy in bulk, get friendly with local farmers, buy a freezer, grow your own fruits, vegetables and herbs. Any or all of these things also help support your local or nearby producers and businesses, and help create stronger communities, which are good things!
