Inflammation - Eating Anti-Inflammatory Foods


Are there really diets out there that can reduce inflammation? Do they work? Scientists have found that there is a relationship, in part, between what we eat and inflammation. They've even identified some compounds in food that can reduce inflammation and others that promote it. There is still a lot to learn about just how diet and inflammation interact, and research, as of yet, is not at that point where a specific foods or groups of foods can be singled out as being beneficial for people with arthritis. We are beginning to get a clearer picture of how eating the right way can reduce inflammation.

So why are we so concerned about inflammation? Inflammation is the body's natural defense to infections and injuries. When something goes wrong the body's immune system goes to work to inflame the area, which serves to get rid of the invader or to heal the wound. Inflammation can cause pain, swelling, redness, and warmth, but this goes away as soon as the problem is solved. This is good inflammation.

Then we have chronic inflammation, the type that's familiar to people with rheumatoid arthritis (RA), lupus, psoriatic arthritis, and other types of "inflammatory" arthritis. Chronic inflammation is the type that will not go away. All the types of arthritis that are mentioned above are a disorder of the immune system creates inflammation and then doesn't know when to shut off. Inflammatory arthritis, chronic inflammation can have serious consequences, permanent disability and tissue damage can be one if it isn't treated properly. Inflammation has been linked to a full host of other medical conditions.

Inflammation has been found to contribute to atherosclerosis, which is when fat builds up on the lining of arteries, raising the risk of heart attacks. Also, high levels of inflammation proteins have been found in the blood of people with heart disease. Inflammation has also been linked to obesity, diabetes, asthma, depression, and even Alzheimer disease and cancer. Scientists think that a constant level of inflammation in the body, even if the level is low, can have a number of negative effects. Research shows that diet can reduce inflammation; in theory an inflammation-lowering diet should have an effect on a wide range of health conditions.

Researchers have looked for clues in the eating habits of our early ancestors to discover which foods might benefit us the most. They believe those habits are more in tune to our eating habits with how the body processes and uses what we eat and drink. Our ancestor's diet consisted of wild lean meats (venison or boar) and wild plants (green leafy vegetables, fruits, nuts, and berries). There were no cereal grains until the agriculture revolution (about 10,000 years ago). There was very little dairy, and there were no processed or refined foods. Our diets are usually are high in meat, saturated (or bad) fats, and processed foods, and there is very little exercise. Nearly everything we eat is available close by or as far away as our computer and the click of a mouse.

Our diet and lifestyles are way out of whack with how our bodies are made from the inside out. While our genetic make-up has changed very little from our early beginnings, our diet and lifestyles have changed a great deal and the changes have gotten worse over the last 50 to 100 years. Our genes haven't had a chance to adapt. We aren't giving our bodies the right kind of fuel, it's as though we think of our bodies as engines in a jet plane when instead they are like the engine in the very first planes. There are some foods that we are putting into our bodies, especially because we are eating way too much of them, that are affecting our health in a bad way.

There are two nutrients in our diets that have attracted attention, are omega-3 fatty acids and omega-6 fatty acids have been part of our diets for thousands of years. They are components in just about all of our many cells and are important for normal growth and development. Both of these acids play a role in inflammation. In several studies it was found that certain sources of omega 3's in particular, help to reduce the inflammation process and that omega 6's will raise it.

Now this is the problem, the average American eats on average about 15 times more omega 6's than omega 3's. While our very early ancestor's ate omega 6's and omega 3's in equal ratio, and it is believed that this is what helped to balance their ability to turn inflammation on and off. The imbalance of omega 3's and omega 6's in our diets is believed to contribute to the excess of inflammation in our bodies.

So why is it that we eat so many omega 6's now? Vegetable oils such as corn oil, safflower oil, sunflower oil, cottonseed oil, soybean oil, and the products made from them, such as margarine, are loaded with omega 6's. Even many of the processed snack foods that are so readily available today are full of these oils. Based on the best information of the time, was to use vegetable oils like those mentioned above instead of foods with saturated fats such as butter and lard. It looks like the consequences of that advice may have contributed to the increased consumption of omega 6's and therefore causing an imbalance of omega 3's and omega 6's.

You can find omega 6's in other common foods such as meats and egg yolks. The omega 6 found in meat is the fatty acids that come from grain-fed animals such as cows, lambs, pigs and chickens. Most of the meat sold in America is grain fed unlike their grass-fed cousins who contain less of those fatty acids. Wild game such as venison and boar are lower in omega 6's and fat and higher in omega 3's than the meat that comes from the supermarkets where we shop.

You can get omega 3s in both animal and plant food. Our bodies can convert omega 3s from animal sources into anti-inflammatory compounds more easily than the omega 3s from plant sources. Plant foods contain hundreds of other healthful compounds many of which that are anti-inflammatory, so don't discount them all together.

There are many foods that are high in omega 3s and that include fatty fish, especially fish from cold waters. Of course everyone knows about salmon but did you know that you can also find omega 3s in mackerel, anchovies, sardines, herring, striped bass, and bluefish. It's also widely known that wild fish are better sources of omega 3s than the farm raised ones. You can also buy eggs that have been enriched with omega 3 oils. There are several excellent sources of omega 3s in plants that are leafy greens (like kale, Swiss chard, and spinach) as well as flaxseed, wheat germ, walnuts, and their oils.

You can also get omega 3s in supplements (often as fish oil); this source has been shown to be beneficial in some instances. You should take with your doctor before you take a fish oil supplement because it can interact with some medications and under certain circumstances can increase the risk of bleeding. I take a prescribed omega 3 supplement because my doctor had told me that the ones you get in the supermarket or health food store are not pure, they have other additives that do absolutely nothing to help. There are other fats that are contributors to clogged arteries, the "bad" or saturated fats found in meats and high-fat dairy foods, these are called pro-inflammatory.

There are also the Trans fats that are relatively new to the cause of heart disease. These Trans fats can be found in processed convenience and snack foods and can be spotted by reading the labels. They can be identified as partially hydrogenated oils, often soybean oil or cottonseed oil. But, they can also occur naturally in small amounts in animal foods. The thought is that they contribute to the pro-inflammatory activities in our bodies and the amounts we eat today are staggering.

Antioxidants are substances that prevent inflammation causing "free radicals" from over taking our bodies. Plant foods such as fruits, vegetables (including beans), nuts, and seeds carry high amounts of antioxidants. Extra-virgin olive oil and walnut oil are very good sources of antioxidants, also. These foods have long been considered the basics for good health, and can be found in fruits and vegetables with colorful and vibrant pigments. The more colorful the plant, the better they are for you, from green vegetables, especially leafy ones, to low-starch vegetables, such as broccoli and cauliflower, to berries, tomatoes, and brightly colored orange and yellow fruits and vegetables.

I bet you're wondering what this has to do with Arthritis. Well, there has been some research on diet and arthritis, mostly focusing on RA. There was a study that looked into a bunch of other studies on diet and RA and found that diets high in omega 3's had some effect on reducing the symptoms of RA. There was yet another study published in 2008, that found eating omega 6 fatty acids and omega 3 fatty acids in a ratio of 2 or 3 to 1 (a low ratio compared to the 15 to 1 ratio in most people's diet) decreased the inflammation in people with RA. There was also another study that found taking omega 3 may also allow people to reduce their use of no steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin) and naproxen (Aleve). But these and other studies don't offer enough evidence to prove that there is any particular anti-inflammatory diet that can have a real impact on arthritis symptoms. It doesn't mean that the diets are harmful; it just means that there may come a day when research may be able to prove their benefits. In the future, diet may be considered one of the many tools along with exercise and medicine that can be used to ease the symptoms of arthritis.

We don't have to revert back completely to the caveman to eat the anti-inflammatory way to benefit from the anti-inflammatory diet. Just eating a healthful diet that is recommended today is right on track. Our chief strategy should be to balance the amount of modern day foods with the foods of long ago, which were rich in the inflammation reducing foods. Really, all we have to do is replace foods rich in omega 6 with foods rich in omega 3, cutting down on how much meat and poultry we eat while eating oily fish a couple of times a week and adding more varieties of colorful fruits and vegetables, and while whole grains were not a part of our early ancestor's diet, it should be included in ours. Be sure that it is whole grains and not refined grains because they contain many beneficial nutrients and inflammation-tempering compounds. Researchers have found that eating a lot of foods high in sugar and white flour may promote inflammation, although there is more studying that needs to be done on the subject.

The amounts of knowledge we have on how the body works and how our ancestor's ate is helping to confirm the old adage: "You are what you eat." But, there is still more we need to learn before we can prescribe any one anti-inflammatory diet. Our genetic makeup and the severity of our health condition will determine the benefits we get from an anti-inflammatory diet and unfortunately there is doubt that there will be one diet that fits us all.

Also, what we eat or don't eat is just a small part of the whole story. We are not as physically active as our ancestors and physical activity has its own anti-inflammatory effects. Our ancestors were also much leaner than we are and body fat is active tissue that can make inflammatory producing compounds.

Anti-inflammatory eating is a way of selecting foods that are more in tune with what the body actually needs. We can achieve a more balanced diet by going back to our roots. If you look at the diet of the people of the Bible, you will find that they, like our caveman ancestors, were more active and their diets consisted of much the same things as our caveman ancestors. They also had no choice but to walk everywhere they wanted to go, there was no such thing as cars or trucks. While we have it easier today, our health has suffered greatly from it.
