Salt – is it bad for you?

Today’s post is about the myth that ‘Salt is bad for you’.

There is a lot of information available in regards to salt and health. I found many health articles reporting on how bad salt is for our health. Conversely, there are also an equal number of articles reporting that it is good for our health.

So what is right?

There are 2 million medical articles published every year regarding our health and sorting out this information was a challenge.

The fact is that the human body needs some salt for good health. Consuming too much may increase the risk of developing high blood pressure, which is a risk factor for other diseases. Too little and the body also suffers.

The trick is to consume a moderate amount. Statistically, many people are consuming too much ‘hidden’ salt. The rise in processed, packaged and canned foods are the issue as they usually contain added salt.

Water and Real Salt are essential for life

 The first thing doctors will do in hospital is put you on a life saving saline drip. We were born out of a water salt sack into a world that is 73% water salt solution and have a body that is 73% water and a brain that is 85% water.

The human body contains many salts, of which sodium chloride is the major one. This makes up around 0.4 per cent of the body’s weight at a concentration pretty well equivalent to that in seawater. So a 50kg person would contain around 200g of sodium chloride (approx. 40 teaspoons).

Sodium is a vital nutrient. It helps to maintain fluid balance and cardiovascular function. Sodium is absorbed from the gastrointestinal tract, always bringing water along with it. It is the major mineral in plasma, the fluid component of blood, and in the fluids that bathe the body’s cells. Without enough sodium, all these fluids would lose their water, causing dehydration, low blood pressure, and death.

Fortunately, it only takes a tiny amount of sodium to prevent this scenario. The body, in its wisdom, can make do with remarkably small amounts of sodium. In fact, some isolated population groups in the world manage perfectly well on just 200 mg a day. And when dietary salt is in short supply, the body can conserve nearly all its sodium, dramatically reducing the amount excreted in urine and shed in sweat. Remember that water always follows sodium, and you’ll understand why your skin is dry and your urine scant and concentrated when you are dehydrated and conserving sodium.

To be sure its supply of salt and water is just right, the body has developed an elaborate series of controls. The blood vessels and brain signal the kidneys to retain or excrete sodium as needed; they also fine-tune the sensation of thirst so you’ll provide water in amounts that match the body’s sodium supply.

How much should we consume?

The National Health and Medical Research Council set an ‘Adequate Intake’ of 460–920 mg of sodium per day. This corresponds to 1.15 – 2.3 grams of salt. Most Australian adults have a daily salt intake of about 10 grams. A ‘Suggested Dietary Target’ of 1600 mg of sodium (equivalent to about 4 grams of salt) has been set for Australian adults.                                             (Sources – www.chriskresser.com www.nutritionaustralia.org www.health.harvard.edu )

 

The best way to ensure a moderate salt intake is to consume less processed and packaged foods. Only add salt when cooking or at the table. Choose a less processed salt, therefore also gaining some trace minerals.

Sweat and sweating

Today’s topic is about sweat, sweat glands and sweating.

This stems from an article I read this morning discussing whether we shower ‘too much’. It quoted a study conducted by the University School of Nursing in Columbia, which claims we don’t need to wash once a day.

The idea being that the body does a good job of managing it’s own bacteria and too much soap can kill off the good stuff. According to the study, showering twice a week is enough, as long as you are regularly washing your hands and changing your clothes.

Scott has recently been studying Biology and this article created a discussion about sweat and sweat glands.

Maybe it doesn’t get as hot and humid in Columbia as Queensland.

I am sure that most of us have found that a crowded train or bus can sometimes be a bit smelly at the end of a hot summer day. Usually this is a result of sweating and for some people this means body odour.

Sweat itself isn’t smelly at all; it’s the bacteria that feed on the sweat and some of the expelled toxins that cause the offensive odour.

Showering doesn’t actually damage the skins bacteria; it’s the soaps we use that can do this.

 The technical stuff …

Sweat glands are used to regulate temperature and remove waste by secreting water, sodium salts, and nitrogenous waste (such as urea) onto the skin surface.

We have two different types of sweat glands: eccrine sweat glands, which are distributed over the entire body, and apocrine sweat glands, located on the scalp, armpits, and genital area.

Interesting fact – we are born with anywhere between 2 million and 4 million sweat glands. The number of such glands we have will determine, in part, how much we sweat. As we age, our sweat glands actually decrease in size and become less effective.

As the body’s’ temperature rises, it will automatically perspire to release salty liquid from the sweat glands to help cool it down.

This is controlled by our autonomic nervous system, which cannot be consciously controlled. However, certain emotions, such as anxiety, anger, embarrassment, or fear, can prompt us to sweat more.

 Sweating is beneficial

The skin is the largest organ of the body, and serves important roles just like any other bodily organ. Sweating actually helps the body in many ways:

– It maintains the body’s temperature to keep it from overheating

– Sweat expel toxins, which supports proper immune function and helps prevent diseases related to toxic overload

– It kills viruses and bacteria that cannot survive in temperatures above 37 degrees Celsius.

– Sweat also cleans the pores, which will help eliminate blackheads and acne.

Despite its many health benefits, most of us use some kind of product to control or stop the sweating process.

 And body odour…..

 There are many different factors that can contribute to body odour.

Some studies into body odour have revealed that our diet plays a large role. This is probably due to the sweat expelling the toxins from the body.

This subject, however, maybe a topic for another post.

Inflammation and the Immune system

Todays post is about Inflammation,

Last week I wrote about the Immune System and how when it is compromised, we get sick. Well, this week I am going to expand on that subject.

One of the symptoms of a compromised immune system is Inflammation.

There was an article in todays Body & Soul that focused on this issue. Finally scientists are saying that Inflammation in the body is one of the major causes of illness. Many Naturopaths and practitioners of complimentary medicine have been saying this for years.

Scott and I first heard about Inflammation in the body and its relationship to illness approximately 8 years ago.

Normally Inflammation is a good thing. It’s a sign of the body’s defense system fighting infection or repairing damage. This is all well and good when our immune system is working well. However, as I mentioned last week, many of us have a compromised immune system due to the stressors we put on it.

We often suspend the body’s process of using inflammation to deal with issues. We start to feel the aches and pains and take anti-inflammatories. Therefore the body doesn’t get to complete its healing processes.

The result being that instead of only calling on our inflammatory defences when we are injured or sick, we’re increasingly triggering the response day in, day out. This creates a situation where our body is consistently emitting small quantities of inflammatory compounds. These levels are often too low to create noticeable symptoms.

There have been recent studies linking high levels of inflammation in the body with some major health problems, such as cancers and heart disease.

 So where does the inflammation come from?

Some is produced inside the body. Excess weight is a cause as fat cells excrete inflammatory substances. We also create it by not taking care of ourselves; stress causes the response as well as lack of sleep. If we soldier on with our aches and pains, ignore allergies and if we don’t look after our teeth, our levels of inflammatory chemicals rise.

Another cause is many of the foods that are a large part of the Western diet.

Foods such as sugar, alcohol, high fat meats, fried foods and refined grains cause inflammation.

 How do we reduce our inflammation?

 The good news is diet can also be used to protect us against inflammation. There is scientific evidence to show that there are foods that reduce inflammation in the body. These are green leafy vegetables, onion, garlic, herbs and spices such as ginger, turmeric and pepper. So by reducing our intake of the Pro-inflammatory foods and increasing the Anti-inflammatory foods in our diet, we are taking steps to lower the inflammation in our bodies.

This strategy along with improving our sleep, reducing our stress and getting some exercise, goes a long way to improving our immune system ability to cope.

A stronger immune system is a stronger, healthier body.
