Last week I briefly mentioned that sugar cravings can be minimized by balancing your vitamins and minerals – in particular by taking an omega 3 supplement. I’ve had some questions about the difference between taking fish oil and flax oil to get your omega 3s, and today I’m going to tackle that question.
But first, why talk about omega 3′s when we’re dealing with sugar cravings?
We’ve discussed how sugar cravings are basically just our brains asking for pleasure. The dopamine receptors get happy when we eat sweets, so the more sweets that we eat, the happier our brains get. That is, until we stop eating sweets and our brains and our bodies get cranky.
As it turns out, deficiencies in omega 3s actually decrease our perception of pleasure. Just like we talked about last week with people who have fewer dopamine D2 receptors, when your body doesn’t get as much pleasure from the “regular” dose of sugar, it needs a bigger dose in order to feel good. To put it in scientific terms, “a given level of perception of a sweet taste requires a larger quantity of sugar in subjects with alpha-linolenic acid deficiency.” It would seem that the less omega 3s that a person eats, the more sugar they would need to eat in order to satisfy their sweet tooth.
Clearly, it’s important to make sure we’re getting the proper intake of omega 3s.
Doctors say that fish oil is a superior source of omega 3. If that’s true, what’s a vegetarian to do?
The reason that doctors advocate for fish over flax oil is pretty simple. Fish oils contain two very important long-chain omega 3′s known as EPA and DHA. Flax oil contains ALA, which is an omega 3 that the body can use to turn into EPA and DHA. However, the process by which the body converts ALA into EPA and DHA is highly inefficient, and only about 5-15% is actually converted into EPA and DHA. In order to get the same amount of EPA and DHA that is found in fish oil, we would need to consume 5-6 times the amount of ALA from flax oil. Do you really want to take that much flax oil every day? It’s starting to sound inefficient, isn’t it?
But there’s a catch. Fish aren’t naturally high in EPA and DHA…just like us, they get it from what they eat! Fish eat microalgae, particularly zooplankton and phytoplankton, and then store the EPA and DHA in their fat. So why not skip the fish and go directly to the source? Spirulina and astaxanthin are two wonderful microalgaes that are excellent sources of DHA. By eating more algae in addition to omega 3-rich foods like walnuts and chia seeds, our bodies can take in enough DHA and ALA to optimize our levels of DHA, ALA and EPA.
Conclusion?
Control your cravings for sugar by eating algae, walnuts and chia seeds, or by taking a high-quality fish oil from brands like New Chapter, Carlson or Nordic Naturals. Sounds like a pretty good plan of attack, doesn’t it?
