Vegans and Vitamin B12
•
•
Vegans are called total vegetarians because they do not eat any animal
product and do not use animal products at all.
Vegans generally have supplements with vitamin B12
– B12 is a vitamin that can be stored in the body for up to 4 years.
• Deficiency not recognized by vegans because it takes so long to
surface
• Plant sources only provide a small amount of B12
– Methylcobalimin is the active and most readily aborbed form of vitamin
B12
• Methylcobalimin should be looked for when looking for supplements
• What is the big deal health-wise with a lack of B12?
– Problems with asthma, depression, nerve damage, low sperm count,
multiple sclerosis, insomnia, and a few others.
– Body’s ability to absorb B12 diminishes with age (problem later for
college students)
Infants and Children
•
•
•
Infants and children practicing a vegetarian diet can be successful, but there
are concerns for youngsters
– Iron, B12 and calcium deficiencies may take place like with all vegetarians
– Children are at a higher risk for vitamin deficiency
• Body’s ability to absorb nutrients while developing is lower
• Kids may eat foods that make them feel full before they reach their
needed calories
Overall a vegetarian diet should be monitored by a professional when it comes
to children’s nutrient needs and supplements
A vegetarian diet for children should include:
–
Calories and fat
•
•
–
Protein and Calcium
•
•
•
–
Canola oils (in pastas generally)
Dip bread in oils
Soy Products
Legumes
Fortified Orange juice and soy milk
Vitamin B12, Iron and Zinc
•
•
•
Fortified cereals
Supplements
Zinc: sunflower seeds; Iron: pumpkin seeds
Learning Something…

calories.
• A partial vegetarian diet could help most average American’s. In the
article “Go Veggie Once a Week” it suggests the average American
eat a vegetarian diet once a week.
– Veggies are low in fat and calories
– CV health and lowers risk of breast cancer
– High in fiber (keeps you feeling full longer)
• Diabetes prevention and Bone building may
even be a benefit to a vegetarian diet.
– Increased fiber, lower cholesterol
– More fruits and vegetables, less fats
– Animal protein may be bad for your bones
