by Ashleigh Feltham,  Accredited Practising Dietitian and Accredited Nutritionist.[/vc_column_text][vc_empty_space height=”30px”][vc_column_text css=””]Diet is one of the factors that contributes to a successful pregnancy. Including a range of the right foods provides your body with the energy it needs and essential nutrients for a healthy mother and baby. Vitamin B12 in particular is crucial for a successful pregnancy.[/vc_column_text][vc_empty_space][vc_column_text css=””]Vitamin B12, also called cobalamin, is one of eight B vitamins. B12, a water-soluble vitamin, is vital for keeping your nerve cells and red blood cells healthy. B12 also plays an important role in promoting tissue, eye and brain health. Natural vitamin B12 is predominantly found in animal food products.[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_single_image image=”2326″ img_size=”full” onclick=”link_image” css=”” qode_css_animation=””][/vc_column][/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_empty_space][vc_column_text css=””]

B12 is also needed to make DNA, which stores your body’s genetic material. Being deficient in B12 can affect your memory and can be misdiagnosed with conditions such as dementia, especially in the elderly.

Research shows that suboptimal levels of vitamin B12 during pregnancy has negative effects on the health of the infant, both in the short and long term.

A literature review highlights the effects of vitamin B12 deficiency on pregnancy outcomes for both the mother and infant. It shows that B12 deficiency is associated with high blood levels of homocysteine concentrations at 18-20 weeks of gestation. Homocysteine is an amino acid found in your blood. High levels of this amino acid is linked to poor health outcomes and disease states. There is a correlation between these high homocysteine blood concentrations and damage to the DNA of the mother.

This DNA damage is associated with an increased risk of developing preeclampsia and intrauterine growth restriction. Preeclampsia precipitates symptoms of high blood pressure and abnormally high levels of protein in the urine, called proteinuria, in the twentieth week of pregnancy.

Another study investigated the effects of vitamin B12 deficiency on pregnancy outcomes. Researchers conclude that there is an association between vitamin B12 deficiency and an increased risk of developing megaloblastic anaemia, a type of anaemia that causes very large red blood cells.

Megaloblastic anaemia during pregnancy is linked to many ill health outcomes for the baby. These outcomes include an increased risk of low birth weight, permanently effecting the cognitive development of the foetus, an increased risk of neural tube defects, increased risk of re-occurring pregnancy losses, anaemia and intrauterine growth restrictions.

There is also a link between low concentrations of vitamin B12 in the blood and an increased risk of the infant developing insulin resistance as well as a higher likelihood of being born with a congenital heart defect.

[/vc_column_text][vc_empty_space][vc_column_text css=””]This research reinforces the importance of including enough foods in your diet that are sources of vitamin B12. B12 is naturally found in animal foods, such as:

• Eggs, mostly in the yolk
• Dairy – cow’s milk, cheese, yoghurt
• Red meat – beef, lamb, game meats like kangaroo, pork
• White meat – all varieties of poultry
• Fish – all varieties, particularly tuna and haddock
• Shellfish – all varieties

[/vc_column_text][vc_empty_space][vc_column_text css=””]Vitamin B12 can also be added to food or drinks through fortification, such as in soy milk, nutritional yeast, cereals and rice milk.[/vc_column_text][vc_empty_space height=”30px”][/vc_column][/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_single_image image=”2330″ img_size=”full” css=”” qode_css_animation=””][vc_empty_space height=”30px”][vc_column_text css=””]Take home message:

Vitamin B12 is essential for health throughout your life. This is true from the beginning of development in the womb, when the mother is the single source of nutrition for growth and development.
