Understanding Acid and Alkaline and How the Body Detoxifies Itself through the Key Organs

With the Autumn Equinox rapidly approaching many people’s thoughts turn to eating and drinking alkalising foods to prepare the body for the winter months ahead and support the detoxifying organs.

Top Ten Alkalising Foods:

Lemons, Cucumbers, Celery, Avocado, Spinach, Garlic, Kale, Broccoli, Bell Peppers, Wheatgrass

The body is designed to be alkaline and functions optimally in this state. The optimum pH for our blood and body tissues is around 7.35-7.45. This is slightly above the neutral pH level of 7 which is between a pH of 0 (totally acidic), and a pH of 14 (totally alkaline). However, a lot of our everyday foods cause our body to be in a constant state of acidity. A constant state of acidity may trigger longterm chronic diseases. An alkaline diet helps to balance the pH levels of fluids in the body, including blood and urine.

The body naturally detoxifies itself through the following key organs:-

The Skin

One of the largest organs in the body, it is estimated that it covers 20 square metres. The body uses the skin to eliminate wastes in sweat. Strong smelling sweat whilst detoxifying may indicate a high level of toxins.

The Lymphatic System

This is part of the circulatory system and has immune functions. There are many lymphatic vessels and glands throughout the body and they filter out unwanted wastes, toxins and foreign organisms like bacteria before returning them to the circulation to be eliminated by other organs.

The Lungs

The lungs are responsible not only for the intake of oxygen but also for exhaling the waste gas carbon dioxide. During times of irritation and infection the lungs may allow excretion of other wastes carried in the blood from the liver.

The Digestive Tract

Toxins and wastes are deposited in bile by the liver. Bile is stored in the gall bladder and is released into the intestines where it travels down the digestive tract to the colon. The colon is responsible for absorbing any useful compounds and water from the stool and the remainder is eliminated during a bowel movement.

The Liver

This is the main detoxification organ and is responsible for the manufacture of several enzymes and detoxification pathways designed to breakdown and enhance elimination of toxins and wastes. Once blood flows through the liver and toxins and wastes have been dealt with they are sent for elimination through the bowel or kidney.

Kidneys and Urinary Tract

The kidneys contain many tiny structures that filter out wastes and toxins from blood and these are transported to the bladder ready for elimination. The kidneys are vital for elimination and if they are unable to filter out toxins effectively it can seriously affect health.

Try And Reduce Your Exposure To Toxins

Toxins are literally all around us! We breathe them in, we eat them, we put them on our skin and we make toxins during normal day-to-day bodily functions. Common sources of toxins come from:-


  • Dioxins and mercury in certain types of fish
  • BPA in canned foods and water bottles
  • PAHs when grilling red meat at high temperatures (forming smoke)
  • BHA and BHT in processed foods
  • Sodium Nitrite/Nitrate in processed meats like ham and salami
  • Pesticides and fertilisers


  • Phthalates in nail polish, perfume, shampoo, soaps and deodorant
  • Parabens in make-up, hair products, body washes and moisturisers
  • Fluoride in toothpaste


  • Heavy metals
  • Chlorine in swimming pools
  • PCBs in tap water and soil

A 3-5 day light fruit and vegetable diet may help alkalise the body and is something which can be safely done at home. It may be enhanced by booking a colonic with your Colon Hydrotherapist.

The diet can be a mixture of juices, smoothies and soups. A temporary liquid diet allows for better digestion and absorption but by including some fibre supports bowel function.

For ideas on how to make your own go to some of the UK juice delivery sites as they are very informative.

There are various options and if you would rather include some food, you could do a three-day juice, soup and food diet.

S. Houghton, Kent.

"I met Fiona at a networking event about two years ago where she was giving a talk on Colon Hydrotherapy, and was immediately impressed with her knowledge and quiet, calm manner. I have been seeing Fiona for nutritional advice and regular colon hydrotherapy treatments ever since and highly recommend her. (I had been looking for someone to go to for colonics for years, and was very happy to finally find someone I felt comfortable with). Fiona gives regular talks to groups and offers her excellent treatments in Tunbridge Wells, Battle and Hastings.  She works to a very high professional standard and is gentle, caring and sensitive. I recommend her to many of my own clients as I feel that nutrition and colon hydrotherapy is so key to overall health and well being - certainly critical to skin condition!"
