Foods and Nutrients that may benefit T cells

T cells are a group of white blood cells with immune functions that may be beneficial or which may promote inflammation. They can change from one type of T-cell to another based on the amount of oxidative stress chemicals present in their surroundings. Our own body can produce antioxidants that reduce oxidative stress when we have adequate Nrf2. We also can get antioxidants from foods and often the foods that are good sources of antioxidants also contain phytonutrients that promote our own production of Nrf2 which then can help us produce our own types of antioxidants. Other nutrients are also helpful for promoting T cells to become the less inflammatory producing types. (1)

Reduced antioxidant production and prevalence of the more inflammatory type of T cells may be involved in aging and many types of chronic illnesses including cardiovascular diseases, neurological disorders, carcinoma’s and leukemia’s, autoimmune disorders, inflammatory bowel disease and vitiligo. For more details see: (1) Figure 13)

Vitamin B6

Vitamin B6 (pyridoxal, pyridoxal-5-phosphate, (P5P), pyridoxine, and pyridoxamine):

Food Sources of Vitamin B6 include:
  • fortified cereal, barley, buckwheat;
  • avocados, baked potato with the skin;
  • beef, poultry, salmon;
  • bananas, green leafy vegetables;
  • beans, nuts, sunflower and pumpkin seed kernels.
Symptoms of a B6 deficiency may include:
  • A severe deficiency of vitamin B6 may cause seizures;
  • other neurological (nervous system or brain) symptoms affecting mental health may include irritability, confusion, and/or depression;
  • the earliest signs of a B6 deficiency might be observed first in the mouth where the tongue may be swollen and painful and become smooth looking and have a bright magenta color; mouth ulcers and cracks or fissures at the corners of the mouth may also occur;
  • and a weakened immune system may occur with a deficiency of vitamin B6.

  • Three B vitamins, B6, B12 and folate, are all necessary for the breakdown of homocysteine, which at elevated levels may increase risk of heart disease. So deficiency of any one of the three B vitamins, B6, B12 and folate, may be involved with symptoms or a diagnosis of heart disease.

  • Symptoms of PMS (Pre-menstrual Syndrome) and symptoms of prenatal nausea and vomiting may be helped by supplemental B6 intake. This suggests a deficiency may be involved in the underlying cause of the symptoms or that an increased need for the nutrient occurs before menstruation and during pregnancy. All B vitamins are important during pregnancy as they are involved in the growth of new cells and are needed for converting sugar into usable energy.

The skin & GI tract have a rapid cell growth rate which requires energy.
B vitamins are involved in both cell growth & energy metabolism.

B vitamins work together as a group to help breakdown the sugar glucose into a usable form of energy.

Areas of the body that have a short life cycle for cells are the first areas affected by deficiency of B vitamins because new cells need energy to grow and the B vitamin group are also involved in other chemical reactions that are necessary for the growth of new cells. The lining of the intestinal tract can have a cell turnover rate of just one week and the tongue is part of the gastro-intestinal (GI) tract and has a similar quick rate of cell growth.

The skin at the corners of the mouth and the lips in general may also have a slightly quicker rate of cell turnover than other areas of the surface skin. Our outer skin and the lining of the GI-tract are similar and considered part of the same organ system.

“Deficiencies of niacin, riboflavin, pyridoxine, folic acid, or vitamin B12,  resulting from poor diet or from the administration of antagonists, may cause a sore, beefy-red tongue without a coat. In the chronic vitamin deficiency state, the tongue may become atrophic and smooth.”                   – “The Tongue – Clinical Methods – NCBI bookshelf  https://www.ncbi.nlm.nih.gov/books/NBK236/

Pyroluria:

Pyroluria may be a genetic problem that causes increased urinary loss of B6 and zinc for some people. For patients with the condition adequate amounts of the nutrient cannot be readily obtained from food sources and large dose supplements are needed on a daily basis of both vitamin B6 and the mineral zinc. The condition is generally not assessed for or treated by the current medical system as it is not easy to diagnose. Anxiety is a primary symptom, migraine headaches and reduced tolerance for stress may also be symptoms. This post of mine has links and sources for more information: https://effectiveselfcare.info/2014/09/22/pyroluria-anxiety-and-deficiency-of-b6-and-zinc

This post by a medical doctor discusses the mental health and other symptoms in more detail. Emily Dickinson and Charles Darwin had similar symptoms. Daily supplements of zinc and B6 and/or the more bioactive form, pyridoxal-5-phosphate, (P5P), can quickly restore more normal health:  http://www.judytsafrirmd.com/pyroluria-mental-health-and-the-immune-system/

Lack of dreaming at night is a symptom of pyroluria likely due to a long term deficiency of vitamin B6. Once treatment with the large dose supplements has been underway for a while it is common for patients to report remembering dreaming at night again. Whether the deficiency of B6 is causing less time to be spent at night in the stage of sleep when dreaming is more likely to occur, or whether it interferes with the ability to remember dreams the next morning, is not known.
