Last week I shared the glands and their functions within the Endocrine System
More about Hormones
Hormones are some of the most powerful chemical messengers found in the body and are secreted by glands that transfer information and instructions from one set of cells to another. They circulate throughout the body but will only affect those cells that have been programmed to respond to their specific message. All hormone levels can be influenced by our general health, stress levels and the balance of fluid and minerals such as salt in the blood stream. This is the reason that it is necessary to have a healthy and balanced lifestyle and diet to ensure the reproductive system is functioning, as it should.
Most of us, when we talk about hormones, are usually referring to the reproductive ones such as testosterone, progesterone and oestrogen. We all know that as we get older our reproductive hormones decrease and both men and women go through a menopause. Women are more affected by this obviously, but men too experience a decrease in testosterone levels and the changes that this brings about.
However, our sex hormones are just three of the many hormones that are produced in our bodies and even though our reproductive abilities may decrease as we get older, the hormones involved are still active within our body. If they and our other hormones are looked after they will contribute to a healthy, energetic and youthful appearance. Sex does not stop when we get middle aged and maintaining a good diet and active lifestyle influence a healthy and functioning reproductive system.
Each gland within the endocrine system may produce one or more different hormone to affect a process in the body. For example the pancreas secretes Insulin, glucagon and Stomostatin. Insulin and glucagon are secreted according to the level of blood sugar and Stomostatin is the referee to ensure that not too much of either is secreted and therefore blood sugar levels remain balanced.
Hormones are manufactured from components of food, which means that the type of diet you follow has a major impact on keeping hormone levels in balance. Hormones are either protein-like as in insulin, or fat like as in steroid hormones.
A vital element of hormone production is Cholesterol Yes that demon that in the 80s and 90s was banished from our diet in the form of healthy fats and foods such as eggs! We were all recommended to follow a high carbohydrate, low fat diet and of course now we have done a complete U-turn. Not surprisingly this has had a huge impact on our health including increasing rates of obesity, cancer and dementia. Healthy fats and all cholesterol are essential for healthy hormone production, brain and heart health. It is only when the Low Density cholesterol or LDL is oxidised by poor diet, including too many sugars that it can become a health issue.
Whatever the level of hormones produced by particular glands, if they are not communicating when they get to their destination – such as the thyroid gland, kidneys or ovaries – they will not be effective and the ongoing functions they are supposed to stimulate will not be completed. This includes the reproductive process which requires the balance of all most of the hormones for successful production, fertilisation and then development of the egg by a sperm.
How do we create the perfect environment to produce and maintain our hormones?
You cannot go far wrong by eating an 80% natural diet with a wide variety of fresh vegetables, lean protein, healthy fats, wholegrain carbohydrates and fruits. Having healthy hormones is more about what you don’t eat, and the one food that it is a good idea to cut right back is sugars. This is not to say that you should go sugar free especially when the sugar comes from natural sources such as fruits. I do mean the chemically engineered additives in most industrial foods (ie. If it comes in a packet, can or jar). There are certain health benefits to be found in dark chocolate over 52% for example but eating 100gms at a time will just make you fat! A couple of squares a day should do the trick.
What is very important in your diet?
One of the most important food sources is essential fatty acids which are Omega-6 and Omega-3 fatty acids (polyunsaturated fatty acids). The body must have these essential fatty acids, yet cannot make them itself. One of the main functions of essential fatty acids is the production of prostaglandins, which are hormone-like substances that regulate many body functions. They basically control every cell of the body on a second-by-second basis by acting as interpreters between the hormones and the cells they are being delivered too. They are required for energy production, increasing oxidation in the body and metabolic rates. Omega 3 in particular is considered to provide protection against certain cancers including breast cancer.
They are particularly important in balancing all hormones, including the reproductive ones, and the brain does not function without essential fatty acids.
Monounsaturated fats are also important as both these types of fats protect brain cells and the membranes and ensure effective passing of nutrients within the brain. This is particularly important with regard to the health of the hypothalamus which is our master controller.
What part do amino acids play in hormone production?
Amino acids are the building blocks that make up protein, which of course is what we are made of. Vitamins and minerals can’t perform their specific functions effectively if the necessary amino acids are not present. Amino acids are either classified as essential or non-essential. The “non-essential” ones can be manufactured in our bodies but the “essential” amino acids have to be obtained from food.
All hormones require amino acids for their production. For example L-Arginine encourages growth hormones and constitutes 80% of semen, which is why a deficiency causes sterility, and having sufficient of this amino acid can help with prostate problems. L-Tryptophan helps in the production of serotonin and melatonin and assists in the balance of our emotional behaviour. L-Glutamine is helpful for thyroid gland function. Taurine is used for hyperactivity and poor brain function.
What about the health of the other hormone producing glands?
Most of the above applies throughout the body. A diet rich in antioxidants such as Vitamin A, C and E and essential fatty acids and amino acids will promote health everywhere.
Having created a near perfect working environment for the bosses (the Hypothalamus and the Pituitary), it will have a knock on effect on the health of the others:
- Thyroid (metabolism, energy and growth)
- Adrenal Gland (sex drive, stress response and metabolism) and
- Pancreas (Blood sugar levels).
If these organs are producing the hormones they are supposed to, in the right quantities, many of problems we associate with old age would be much more manageable. Including energy and the ability to process our nutrients efficiently keeping us away from degenerative disease such as arthritis.

I am a qualified nutritional therapist with twenty-two years experience working with clients in Ireland and the UK as well as being a health consultant on radio in Spain. Although I write a lot of fiction, I actually wrote my first two books on health, the first one, Size Matters, a weight loss programme 20 years ago, based on my own weight loss of 154lbs. My first clinic was in Ireland, the Cronin Diet Advisory Centre and my second book, Just Food for Health was written as my client’s workbook. Since then I have written a men’s health manual, and anti-aging programme, articles for magazines and posts here on Smorgasbord.
