Nuts, Seeds and Omega 3

Todays post is about nuts and omega 3.

A friend of ours was recently sharing that she had been craving nuts and seeds quite a lot in the past few weeks. She asked if we were aware of this being a symptom of anything.

We were not sure but thought it could mean that her body was craving Omega 3.

I decided to do some research and as usual am sharing my findings.

The health world has been focusing on Omega-3 fats as they play a major role in heart, brain and overall health.

So what is Omega-3?

Omega-3 is a polyunsaturated fatty acid (PUFA), a type of healthy fat.

There are actually three main kinds of omega-3 fatty acids, each capable of providing vital health benefits for the body and mind.

The 3 kinds are – Alpha-linolenic acid (ALA), Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA).

ALA is crucial for normal growth and development. It also helps maintain normal blood cholesterol levels.

EPA helps maintain normal blood pressure levels and reduce inflammation. EPA may also reduce the symptoms of depression.

DHA is important for brain development and function. It can also benefit heart health by reducing blood triglycerides (a type of fat found in the blood).

The body can’t produce these essential fatty acids on its own. It is important to make sure you’re getting enough through dietary sources. If you don’t, you could experience the symptoms of omega-3 deficiency.

In addition, there’s currently no standard test to diagnose an omega-3 deficiency, though there are several ways to analyze omega-3 levels.

To date, few studies have investigated the signs and symptoms of omega-3 deficiency. Therefore I was unable to find any studies to suggest that craving nuts or seeds, was an indicator of low levels.

There are however some other recognised symptoms of omega-3 deficiency.

Main symptoms of low omega 3
  • Hair and /or skin is feeling dry – this is because omega-3 fats help retain moisture in the skin, they also help keep your hair healthy.
  • Feeling anxious or depressed – DHA‘s are known to have neuro-protective and anti-inflammatory effects
  • Dry eyes – essential fatty acids play a role in eye health, including maintaining eye moisture.
  • Blood Pressure is higher that normal – Omega-3s are known as the “heart-healthy fats” and are associated with significantly lower blood pressure levels.

It is relatively easy to ensure good levels of these ‘fatty acids’ in your body simply by eating a varied diet.

Main Food Sources of Omega-3s

Plant oils such as flaxseed (linseed), soybean, and canola oils contain ALA.

Chia seeds, pumpkin seeds and walnuts also contain ALA.

Several types of fish contain omega 3 such as salmon, mackerel, tuna, herring, sardines, anchovies, bass, and cod.

Vegetables such as Brussels sprouts, kale, spinach, broccoli and cauliflower, are good sources of ALA.

Of course there are several other processed foods and supplements available that are fortified with DHA and other omega-3s.

So, in a nutshell, upping your omega-3 intake helps improve your skin and hair, lower your blood pressure and improve your overall heart health.

The brain, food and our weight.

Today I’m writing about the brain, how it’s affected by food and it’s connection to our weight.

With Scott’s study we have some interesting conversations. Usually about the latest things he has learned. Most recently we were discussing the role of our brain plays in regards to our weight and how it’s affected by food.

I thought I would share what we have learned.

How food affects our brain

Interestingly, of our total energy input, our brain actually uses up to 20% of our body’s energy resources. The different compounds in foods affect the production of hormones in our brain, which in turn, govern our moods.

The micronutrients in fruits & veg, such as antioxidants, help to reduce free radicals in the brain, which destroy brain cells. Essential fatty acids such as omega 3 & 6 are essential for the creation and maintenance of brain cell membrane. Proteins & amino acids affect how we feel and behave. The vitamins B6, B12 & folic acid help prevent brain disease.

Most of the energy comes from processing the carbohydrates we eat, to blood sugar.

The types of carbohydrates we eat have different effects on the levels of blood sugar. There are basically 3 types of carbohydrates, starch, sugar & fibre. The ratio of these in the food affects how the body and brain respond.

Simple carbohydrates has less fibre and are therefore processed quickly. This creates more energy, however it is not sustainable. This results in an energy deficit or slump.

Having a diet that contains a broad selection of foods help keep everything balanced.

So we know that different food affects the brain. What is really interesting is that the brain then regulates how much we eat and use for energy according to our weight.

Is the brain connected to our weight?

Researchers in 1982 theorised that the brain has a ‘body weight set point’. Which means that the brain actually has a say in how we put on, or lose weight.

This is the reason that many people plateau when actively trying to lose weight. It is also why many people put the weight back on after losing it.

The set-point theory suggests that body weight is regulated at a predetermined, or preferred, level by a feedback control mechanism. Information from the body is carried to a central controller in the brain, located in the hypothalamus.

The controller uses the information to modulate food intake or energy expenditure to correct any deviations in body weight from the set-point. (Source – www.ncbi.nlm.nih.gov/pubmed/)

According to this theory, body fat percentage and body weight are matters of internal controls that are set differently in different people.

There are several different theories on how to re-set the body’s set-point. Some say it can be done through diet, others say constant intense exercise.

I think that this will vary for each individual as much as our internal controls are different.

Either way, I found it quite interesting to learn about this particular ‘brain – body’ connection.
