Why Eat B Vitamins?

Who knew that vitamins and the foods we eat could have such an impact on our health?  Some people think paying attention to dietary causes of diseases and virulent mental health states is all a bunch of hocus-pocus.  I would suggest that we all think again.  

 This is why we should eat a Balanced amount of foods containing the B Vitamins:

What B Vitamins Do
  • Thiamin
  • Riboflavin
  • Niacin
  • Biotin
  • Pantothenic Acid
  • Vitamin B-6
  • Folate (Folic Acid)
  • Vitamin B-12
B Vitamins are apart of the energy metabolism team.  They assist with BREAKING DOWN carbs, proteins, and fats to convert them into energy that can be used by the cells of our body.  Some of them assist with CONSTRUCTING glucose (sugar/carbs), lipids (fats), and amino acids (protein).  Some of the MVPs they help construct include hemoglobin (made of protein) and DNA (made of sugars).

The BREAKING DOWN and CONSTRUCTION processes of the body = METABOLISM

Thiamin, Vitamins B-6 and B-12 are especially important players in maintaining balance in the Nervous System.   Thiamin and Vitamin B-6 team up with vitamin C  to construct neurotransmitters for the Nervous System.  B-6 and B-12 help speed up the communication between the cells in the body through their role in myelin sheath formation.  Myelin sheath speeds up neuromuscular communication which improves our coordination and response processes.

All B Vitamins are Coenzymes.  Enzymes are needed in all chemical reactions (METABOLISM) in the body.  Many of those enzymes cannot adequately play their position on the team unless their specific B Vitamin Coenzyme is attached.

B Vitamin Deficiencies, Toxicities, and Food Sources
There are different symptoms and diseases with each of the B Vitamins.  Most of Vitamin B Deficiencies are caused by drinking too much alcohol.  Alcohol consumption decreases our ability to absorb and use these vitamins.  For most of the B Vitamins, no symptoms of Toxicity have been reported. The ones that have are caused by overdosing on supplements.


Thiamin
Deficiency:  Beriberi
Symptoms of Beriberi include weakness, apathy, irritability, nerve tingling, poor coordination, and numbness.  Chronic cases include paralysis and changes in the cardiovascular system. 

Thiamin Deficiency:  Beri Beri


Thiamin Deficiency caused by toxic alcohol consumption:  Wernicke-Korsakoffe Syndrome





Food Sources
Protein
Pork
Nuts, Seeds, Legumes (beans) 

Grains
Whole and Enriched Grains

The Numbers
1.1-1.2 mg/day 

Riboflavin 
Deficiency
This deficiency is noticed most around the mouth.  If deficient, we'll experience inflammation of the mouth and tongue.  The corners of our mouth will crack.

Food Sources

Protein
Meats
 
Dairy products

Whole and Enriched Grains

Dark green veggies

The Numbers
1.1-1.3 mg/day

Niacin 
Deficiency:  Pellagra


Symptoms are diarrhea, dermatitis on areas exposed to the sun, and dementia.  Chronic Niacin Deficiency can result in death.

Processes other than drinking too much alcohol that result in poor Niacin intake are consuming a diet based in corn (which prevents adequate Niacin absorption), leaving out fresh fruits and vegetables, whole grains, meats and poultry. 

Toxicity
Getting too much Niacin causes flushing, nausea, skin rash, and tingling in the extremities. 

Food Sources
Protein
Beef
Chicken
Fish
peanuts, Legumes (beans) 

Grains
Whole and Enriched Grains

The Numbers
14-16 mg/day 

Upper Limit:  35 mg from fortified foods and supplements


Biotin 
Deficiency
Symptoms of this deficiency are similar to Niacin Deficiency but also include depression and hallucinations.

Those who down raw eggs or who drink excessive amounts of alcohol reduce their body's ability to absorb Biotin. 

Food Sources
Protein
Liver
Egg yolks

The Numbers
30 micrograms/day  (microgram = 1/1000 milligram)

Pantothenic Acid 
Deficiency
When we are low in Pantothenic Acid, we may experience fatigue and skin rash.

Food Sources
Widespread in foods

Protein
Meat
Legumes (beans) 

Grains
Whole grains

The Numbers
5 mg/day 

Vitamin B-6 
Deficiency
When we're low on Vitamin B-6, we may experience headaches, nausea, or other neurological symptoms.  If we are continuously low, our results may be  convolutions, poor growth, skin lesions, decreased immune function, and anemia.  This is true because Vitamin B-6 plays a crucial role in protein and energy metabolism.

Toxicity
If we consume too much Vitamin B-6 we may experience numbness and eventually damage our nerves.  Again, we don't usually get too much of any vitamin through food sources.  The potential to overdose is when we consume supplements.

Food Sources
Protein
Meat
Fish
Poultry
Nuts, Seeds, Legumes (beans) 

Grains
Whole Grains

The Numbers
1.3-1.7 mg/day 

Upper Limit:  100 mg/day

Folate (Folic Acid) 
Deficiency
Similar to Riboflavin Deficiency, if we are low in Folate we may also experience inflammation of the tongue.  We may also experience diarrhea, which seems to be common among many vitamin imbalances because this is one efficient means by which the body rids itself of toxins.  Long-term Folate Deficiency can result in poor growth.  In pregnant mothers, it can result in babies with neural tube defects like Spina Bifida.  Deficiency can also result in a type of anemia called, Macrocytic Anemi.  Anemia literally means without blood.  Macrolytic anemia affects the blood's ability to carry oxygen to the body's tissues.  Without oxygen, one the ATP (body's energy source) cannot be produced.

Toxicity
If we get too much Folate, it may mask Vitamin B-12 deficiency symptoms, which are nerve damage.  If we are not aware of these symptoms, we could end up with Pernicious Anemia, a type of Macrolytic Anemia that was like a death sentence if you had it back in the 1920s. 

Food Sources
Protein
Seeds, Legumes (beans) 

Grains  
Enriched Grains

Vegetables
Leafy greens

Fruits
Orange juice 

The Numbers
400 micrograms DFE/day 

Upper Limit:  1000 micrograms/day from fortified food and supplements
 
Vitamin B-12 
Deficiency
The main symptom associated with this deficiency is nerve damage.  
The results identified with Vitamin B-12 Deficiency are similar to Folate Deficiency--Pernicious Anemia (Macrocytic Anemia).  More details about Pernicious Anemia:  It is a blood disease where the red blood cells don't divide normally.  They just grow bigger, hence the word Macro (large) -cytic (pertaining to cells).


Food Sources
Protein
Animal products

The Numbers
2.4 mg/day


This is a lot of specific facts on each vitamin.  To try to make sure we get them all in we don't have to target each one individually.  We just need to eat a diet balanced in whole grains, a variety of fruits and vegetables, dairy, and protein.  See The Bottom Line blog post to determine the right amounts of each food group. 

Sometimes we could be running around in circles looking for cures, magic pills, secret remedies for whatever malady we're facing.  The FUNDAMENTAL PRIORITY PROCESS we need to engage in is making sure our diet includes all the macronutrients and micrnutrients that it needs to function at peak capacity.  The following song is a metaphor for just focusing on the priorities. A healthy balanced diet is like a healthy relationship.  Basically, eating healthy (and exercising regularly) IS WHERE IT IS!!!  "The biggest things [or changes we can make] IN THE SMALLEST PLACES."

Why Eat Vitamin C?

What Vitamin C Does
Vitamin C (ascorbic acid) is needed to produce collagen.  Collagen is the glue that holds our body together.  It is the framework of bones, teeth, connective tissue and the walls of our blood vessels.







When cement contractors lay down the foundation of a house, they use metal rods to add a flexible stability to the cement mixture.  Collagen in our bones is like the metal rods in cement.
Vitamin C is used in the construction of neurotransmitters for the function of our Nervous System. Neurotransmitters are an essential part of the communication network in our body which enables our muscles to move.  They enable us to sense stimuli and respond to them.


Vitamin C is also used to construct hormones for the Endocrine System.


It acts as an antioxidant.  There are some "reactive" oxygen molecules hanging out in our body that mess the fine-tuned order up.  Gremlins.  They have been named Free Radicals.  Vitamin C acts as part of the immune system as it neutralizes these Free Radicals before they cause damage.

Moderate increases of Vitamin C have been found to reduce the duration of cold symptoms.

Vitamin C Deficiency 

When sailors went out to sea in the olden days for an extended period of time, they didn't bring enough fresh fruits and veggies that contained Vitamin C so they became deficient and developed a condition called Scurvy.  In Scurvy, our gums become inflamed, swollen, and start to bleed.  Our teeth loosen in their sockets and will eventually fall out if we do not correct the deficiency in time.  We experience internal bleeding in our subcutaneous tissue as well as in our joints.  We bruise easily and our cuts and scrapes do not heal very quickly.  We may feel tired, lethargic, depressed.  In this state we have a hard time remaining balanced in the face of conflict.  We may lose it pretty easily.  So even though most of us are not out at sea, if we don't get plenty of fresh fruits and vegetables--the kind that are rich in Vitamin C--then we may be experiencing at least mild symptoms of its deficiency.  Are you feeling lost at sea?


Vitamin C Toxicity
It's hard to get too much of any vitamin or mineral from our food. If we're taking supplements it can be quite easy to overdose.  Overdoses of vitamin C can cause nausea, diarrhea, abdominal cramps, and sometimes even headaches.  Long term overdosing can lead to kidney stone formation.

 

 

 

  

Vitamin C Sources

The main source of Vitamin C is citrus fruits.   These other foods are also high in Vitamin C.




The Numbers

Adults:  75-90 mg/day


More Specifically
Infants
0-6 mo:  about 40 mg/day
6-12 mo:  50 mg/day

Children 
1-3:  15 mg/day
4-8:  25 mg/day

Males 
Tweens 9-13:  45 mg/day 
Teens 14-18:  75 mg/day
Adults 19 and up:  90 mg/day

Example Servings
1 large orange = 75 mg Vitamin C
1/2 c. broccoli = 35 mg Vitamin C
1 kiwi (2" diameter) = 64 mg Vitamin C
1 red pepper (medium) = 152 mg Vitamin C!

You can look up the nutrient content of any food on the USDA's Nutrient Data Base of its National Agricultural Library.

Why Eat Calcium?

This is why we should eat a Balanced amount of foods containing Calcium:

What Calcium Does


Calcium is used by the Skeletal System to form our bones and teeth.  99% of the Calcium in our bodies is found in and therefore needed by the bones and teeth.


It's used to regulate blood pressure and and blood clotting in our Cardiovascular System.

It is used by our Muscular System in muscular contraction.

Our Nervous System uses it in cellular nerve impulse communication.

The Endocrine System uses it in hormone secretion.

It also helps regulate water balance, metabolism, growth and development which probably can be summarized into the Digestive System.


 

 

 

 

Calcium Deficiency 

When we don't get enough Calcium in our diet, our Endocrine System stimulates the OSTEOCLASTS (Bone breaking down crew) to break down our bone in order to harvest the Calcium for our general body's needs.  

If this happens continuously over time, our bones become less dense.  They become brittle and more susceptible to fractures.  Chronic Calcium Deficiency leads to osteoporosis.  There are not many warning signs over the years that have been identified so if we don't crunch the adequate intake of Calcium numbers for our gender and age, we may not be getting enough Calcium and end up with osteoporosis

 

 

Calcium Toxicity

When there is too much Calcium in the blood metabolic processes and nerve communication become imbalanced.  Over time we can develop kidney stones and other Chronic Imbalanced States.

 

 

 

 

Calcium Sources

The main source of Calcium is dairy products.  














 These other foods are also high in Calcium.









The Numbers

Adults ages 19-50  1000 mg/day
Adult women ages 51-70  1200 mg/day*
Adult men ages 51-70 stays at 1000 mg/day
Adult men over 70  1200 mg/day

*Women need more because we generally have less bone mass than men AND we lose it at a faster rate in the 5-10 years surrounding menopause.
