Parasites

Parasites are organisms larger than yeast or bacteria that can cause infection, usually in the intestines. The most common parasites to infect humans are giardia (Giardia lamblia), Entamoeba histolytica, cryptosporidium (Cryptosporidium spp.), roundworm (Ascaris lumbricoides), hookworm (Ancylostoma duodenale and Necator americanus), pinworm (Enterobius vermicularis), and tapeworm (Taenia spp.).

Infection with parasites can be life-threatening in people with severe impairment of immune function. You should always consult your doctor if you suspect a parasitic infection. Parasite infections can lead to a variety of symptoms, including wind, bloating, diarrhoea, weight loss, abdominal cramping and pain, constipation, nausea, vomiting, loss of appetite, fever, rash, cough, itching anus, and bloody or foul-smelling bowel motions.

Fibre A high fibre diet promotes probiotic organisms that help to control the level of pathogens in the gut, including parasites, Candida, and pathogenic (bad) bacteria. In the case of an existing parasitic infection fibre is helpful, in combination with anti-parasitic herbs, in the removal of parasitic toxins and the restoration of good gut ecology. 3 – 6g per day with glass of water
Probiotics Increases the acidity of the intestines making the environment undesirable for resident and non-resident pathogenic bacteria, parasites and yeasts.

Diet and Lifestyle Factors

 

Reduce or avoid – Sugar, Refined carbohydrates, Saturated and trans fats, Allergens, Fried foods

Increase – Complex carbohydrates, Vegetables, Fruit, Nuts and seeds, Oily fish, Whole grains

High fibre, low saturated fat diets promote healthy intestinal ecology.

When travelling abroad, avoid drinking tap water and eating uncooked foods, foods prepared by street vendors, ice, and fruits that cannot be peeled. All of these are potential sources of parasitic infection. Undercooked fish, meat and poultry can also contain parasites.

Do not drink untreated stream water while camping, as it may be contaminated with giardia.
