The Recommended Dietary Allowance or RDA is part of old guidelines that were first brought about by concern for our country. The government wanted to make certain that military personnel were receiving the nutrients they needed to remain healthy. The standards would be used for more than just the military, but the military was the initial thought. Over the years the RDA has been modified and revised. The modifications and revisions can be results of new scientific information or as new foods become available. Eventually the recommend dietary allowance became part of the RDI, Recommended Daily Intake, which has four separate values to consider. This post is just a quick reminder of the RDA.
The RDA is actually for healthy people . . . .if you are the one of the “one in three” Americans that have high blood pressure, or the one of the “one in three” Americans that have high cholesterol, or one in the large percentage of Americans that doesn’t exercise regularly and/or eat a diet of fast food and/or have a high stress job and/or are overweight/obese/morbidly obese then these guidelines are not necessarily for you. The recommended dietary allowance is for healthy people. The estimated Daily Values that are disclosed on nutrition labels are for healthy people and the people eating a 2000 calorie a day diet.
As you can see the D in RDA stands for dietary, not daily, because we don’t need to eat each recommended amount daily. But I didn’t see the information that explained how that is supposed to average out. But even so, the amounts are based on averages and people who are healthy so it is kind of no wonder that Americans as a whole are not getting healthier. If what we have to follow doesn’t even apply to 1 in three of us. The recommendations really should be taken as very loose guidelines. If you have high blood pressure and/or high cholesterol and you are on medication that brings you back into the normal ranges, then it could be that the RDA might work for you. But it could also be that if you weren’t concerned with the RDA (which remember is meant for healthy people) and you actually ate to be healthy then it could be that a proper diet could make the medication no longer needed.
A great example to point out proof of this is diabetes. You probably know someone who has it. You know they don’t follow the RDA. If they are concerned with controlling it they have a very different diet to follow. You might even know someone who HAD diabetes and they were able to control it and get off the medications with a change in their diet. I have heard a lot of testimony of exactly that happening.
Guidelines for healthy people also applies to the 30 minutes of exercise a day. That 30 minutes is to MAINTAIN health. Again . . . if you are unhealthy and want to improve your health exercising just 30 minutes a day might not do it. More than likely you’re going to need more.
So this is just to help you remember that the dietary guidelines are just there to advise or guide on how one does not become deficient in a nutrient. That is why they are really actually explaining how to stay healthy because they were created for healthy people. And the recommended 30 minutes a day is to maintain health. So for the people with health issues that actually want to use diet and exercise to improve their health they shouldn’t stick to the recommendations. They are only guidelines and they do not apply to us all. We all are individuals and we need to find out what works best for us. There are doctors, nutritionist, personal trainers, dietitians, and a whole group of people who can help. Don’t necessarily rely on the government recommendations to GET you healthy. It is really up to you.

I have mentioned Omega 3 before, but I haven’t said a lot about it. I thought sharing a few things about it would be nice. Omega 3 is an essential fatty acid required by the body. “Essential” means that our body must have it but can’t make it so we need to obtain the nutrient from our diet. Since our cell membranes are made up of fatty acids it makes sense that our body needs fatty acids to function properly. The key is making sure our bodies have the right kind of fat. Omega 3 contains three fatty acids, a-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), and is considered a polyunsaturated fat. Polyunsaturated fat, unlike saturated fat, does not harden at room temperature. Wanting a fat that makes up cell membranes that does not harden is another thing that makes sense, right? Nutrients and waste has an easier time passing in and out of a cell membrane with a liquid consistency than one that is solid.
Research has been done in regards to Omega 3 on diseases and ailments with varied results. Studies continue to reveal Omega 3 helps reduce heart disease risk factors such as high cholesterol and high blood pressure. Omega 3 helps reduce inflammation. We know chronic inflammation is not good because it is linked with or even thought to be the cause of many diseases. Omega 3 could help with autoimmune diseases of which inflammation is present such as asthma, rheumatoid arthritis, inflammatory bowel disease, and diabetes. With many diseases there is often multiple issues so it makes sense that if something helps with one thing it might help with another if it is a symptom or a result of a disease. For instance, many people with diabetes have high cholesterol so, if Omega 3 helps lower the LDL and raise the HDL, that would be of assistance to someone with diabetes. Science is continuing to discover things about Omega 3 and how each fatty acid has different effects on the body.
Omega 3 is interesting in that one of the three ALA is actually not used by the body until it is converted to the other two. Some foods contain ALA, some contain EPA, and others contain DHA or a combination of them. So as always recommended it is good to eat a variety of foods. Eating a variety of foods containing Omega 3 will help ensure you get what you need. Some of the food Omega 3 can be found in is cold water fish, flax seed, walnuts, and what some are calling “Omega 3 eggs”. At present there is not a Recommended Daily Allowance (RDA) for Omega 3, but the consensus is that Americans should be eating more.
According to a the World’s Healthiest Foods website: “the National Institutes of Health recommended that people consume at least 2% of their total daily calories as omega-3 fats.”
You might have heard the claim that Canola Oil is a good source of Omega 3, but then you might have also heard the processing the rapeseed plant goes through and the way the oil is made actually burns off the Omega 3 and becomes transfat. This is one of those things you might want to research and decide for yourself. It is your health.
Other foods containing Omega 3: beans, olive oil, hemp seeds, kale, collard greens, spinach, soybeans, cloves, oregano, green beans — yay, not just fish! I am not a fan of fish although, the Omega 3 in fish is hard to beat, so I probably should start eating it.
Like so many nutrients being discovered as being necessary almost everyday it seems as if the best way to get what the body needs is to eat a variety of foods. The less we eat of over-processes and packaged foods the better. Finding a balance is also important. It just really sounds as if, from all the information I have read, Americans consume less Omega 3 than we should, so — to me — it sounds good to add more to my diet. What about you? Are there ways you can add more healthy foods that contain Omega 3 into your diet?
