Tryptophan

Today’s post is about Tryptophan.

In our last post about Depression, Scott mentioned that the nutrients we need for good mental health include vitamin B6, tryptophan, zinc, iron and folate. So, today we are going to focus on tryptophan.

So, what is it?

Tryptophan is an essential amino acid, meaning that it cannot be produced in the body and so must come from food.

It plays a fundamental role in human nutrition and health and is required for normal growth. The body uses it to create several bioactive compounds including vitamin B6, serotonin and melatonin. It is required for the production and maintenance of the body’s proteins, muscles, enzymes, and neurotransmitters. The liver can also use tryptophan to produce niacin (vitamin B3), which is needed for energy metabolism and DNA production.

Its role in animal and human health can therefore impact on many diseases and conditions.

What is the connection to mental health?

Being one of the main building blocks for serotonin it is quite important to have a plentiful supply. It is a natural sedative and is one reason that you feel sleepy after a big meal of protein like turkey at Christmas. Research has also shown that if you have a low-tryptophan diet, brain serotonin levels drop.

Tryptophan can potentially be used by the body for a lot of different things but most of them lead back to serotonin, so lets have a look.

Because tryptophan helps make serotonin, which is responsible for things like arousal, perception, pain and mood, anything in those areas can be altered by tryptophan. For example, if you are trying to give up smoking, taking tryptophan supplements may help to reduce the cravings by changing your perception. In addition, low amounts of tryptophan in the body may contribute to depression and sleep disorders.

Serotonin also mixes with something called Sam-e to make melatonin that is a big player in the sleep wake cycle. Theoretically it can even be used to help with ADHD as low serotonin can show as poor impulse control.

Can diet make a difference ?

Tryptophan is commonly found in foods that contain protein. Although meat is often a key source of protein for many people, there are also many vegetarian and vegan sources as well as a supplement in powder form.

Interestingly if you suffer from fructose mal-absorption then this can reduce the levels of tryptophan that is available for use.

The following foods are good sources of tryptophan:

Salmon, Poultry, Eggs, Spinach, Seeds (such as pumpkin, sesame & sunflower), Milk, Nuts and Soy products.

So ensuring that your diet contains a variety of these foods can assist in maintaining your body’s levels of this essential amino acid.

 

It is easy to see that within the human body one little thing leads to another and then another. The body is a tangled web of neurotransmitters, enzymes, proteins and things that all interact with each other.

Tryptophan can react with a large number of other substances including herbal remedies so as always consult a professional before taking. Side effects can include tiredness, heartburn, GIT upset and headaches.

All about Magnesium

Todays post is all about Magnesium. I recently read a small article on foods rich in magnesium and how this mineral plays a part in controlling blood sugar. This was news to me, so I decided to do a bit of research into this essential macro mineral.

What is Magnesium?

Wikipedia states that Magnesium is an alkaline earth metal and the eighth most abundant element in the Earth’s crust. It’s also abundant in seawater due to its high solubility. Magnesium is also the 11th most abundant element by mass in the human body.

Why is it important?

Magnesium is necessary for more than 300 chemical reactions in the human body and is used by almost every cell. It’s needed for healthy bones, heart, muscles, and nerves and helps your body control energy, blood sugar, blood pressure, and many other processes.

An adult body contains approximately 25 g magnesium, with 50% to 60% present in the bones and most of the rest in soft tissues. It is absorbed through the bowel and stored mainly in bone and soft tissue.

How our body uses it.

Calcium and magnesium work together in maintaining bone health and preventing osteoporosis. Magnesium is important for bone formation. It helps assimilate calcium into the bone and plays a role in activating vitamin D in the kidneys.

Magnesium plays an important role in carbohydrate and glucose metabolism. Several studies have associated a higher intake with a lower risk of diabetes. It is also necessary to maintain the health of muscles, including the heart, and for the transmission of electrical signals in the body.

Studies have also shown that magnesium can help with migraine headaches, PMS and anxiety. If you were basically healthy, you probably wouldn’t have symptoms from low magnesium unless it went on for a long time. Low levels have been linked to health issues like Crohn’s disease, celiac disease, or insulin resistance. 

Lifestyle choices can also lead to low levels, such as poor diet, gastrointestinal problems, or vitamin D deficiency. Some symptoms of magnesium deficiency include tingly fingers and toes, flu like symptoms, cramping muscles, irregular heart rate, mood changes and constipation.

Getting your daily dose

Magnesium is one of seven essential macro minerals that need to be consumed in relatively large amounts, at least 100 milligrams (mg) per day. The best way to ensure you are getting your daily dose is from food.

Latest research regarding magnesium absorption from gels and creams on the skin is inconclusive. The best sources of magnesium are pumpkin and sunflower seeds, spinach, Swiss chard and other leafy greens, black beans, quinoa and cashews.

Studies have revealed that when the foods are cooked for any length of time the mineral content is significantly less. All the more reason to eat fresh unprocessed vegetables, nuts and seeds as much as possible.

I hope that you found this information as interesting as I have, I wasn’t aware that magnesium played such a big role in our bodily functions.          Sources – (National Institutes of Health – Health Direct –  Medical News Today

Spinach and Iron – myth or fact ??

Today i’m going to tackle the myth that Spinach provides us with lots of Iron.

The idea that spinach contained exceptional levels of iron originated in 1870 with a German chemist named Erich von Wolf. Dr Von Wolf was researching the nutritional benefits of this leafy vegetable. In his notes, he accidentally printed the decimal point in the vegetable’s iron content in the wrong spot. 3.5 grams of iron suddenly became 35 grams, an extremely high amount of iron.

Those figures remained unchallenged until 1937, when it was discovered that the content was 1/10th the claim. The oversight resulted from a misplaced decimal point.

The cartoon character Popeye also popularised the idea of high iron content in spinach. In fact, spinach growers credited Popeye with a 33% increase in U.S. spinach consumption and saving the industry in the 1930s, according to Popeye’s official website.

 The nutrition facts 

Spinach doesn’t have that much more iron than other leafy greens like broccoli and kale. One cup of raw leaves has .81 milligrams of iron, while the same amount of broccoli has .66 mg. and kale has .24 mg.

Although it contains higher levels of iron and calcium, the rate of absorption is almost nil. This is due to it containing high levels of oxalic acid, a food component that inhibits iron and calcium absorption.

Despite its unusable iron and calcium content, Spinach is still a highly nutritious vegetable. It’s rich in several important minerals, proteins, and vitamins. It’s juice is also said to be the most potent for the prevention of cancer cell formation. Research has shown that those who eat spinach daily are less likely to develop lung cancer. It is also a good source of the B vitamin, Folate, that promotes normal foetal development during pregnancy.       (Source – www.innvista.com)

Spinach is often paired with dairy products, especially cheeses in many recipes. In the Middle East and Greece it is often teamed with feta or haloumi, while Italians combine it with ricotta or parmesan. However, pairing this dark green vegetable with dairy can lessen the amount of calcium your body absorbs from the dairy products.

 The different varieties

 

English spinach, or true spinach, is often confused with silverbeet. Spinach, however, has a smaller, flatter leaf and green veins, as opposed to the white veins of silverbeet.

Baby spinach is a flat-leaf green with soft, tender and mild-flavoured leaves. Usually sold pre-washed, it requires no advance preparation. Because the stems are so tender, there is no need to remove them. It’s perfect raw in salads, and can be added at the last minute to many dishes, or used in any recipe requiring English spinach.

Silverbeet is a close relative of spinach and beetroot, and is believed to have originated in the Mediterranean. Silverbeet is also best with the stalks removed and cooked. Cook as briefly as possible to retain maximum nutrient content.

 

So whichever type of spinach you prefer, continue to enjoy it. Just don’t rely on it as a source of iron or calcium.
