Mnemonics on nutrition

We’ll keep updating this section.
Please, please, please feel free to add your mnemonics as well ^__^

Deficiency of vitamin B1:
Thiamine deficiency causes Ber1 Ber1 (B1).

Deficiency of vitamin B2:
“A2 B2 C2”
A2 - 2 ATPs (FAD and FMN are derived from riboFlavin)
B2 - Vitamin B2
C2 - Cheilosis, Corneal vascularization
Let’s call it ri-two-bo-flavin!

Deficiency of vitamin B3:
“B3 causes D3”
Dermatitis, Dementia, Death.
Random fact: P3llagra also tends to occur in areas where people eat maize (or corn, the only grain low in digestible niacin) as a staple food.
Mnemonic: Corny people can’t be nice. (Corn can’t have niacin)

Protein deficiency diseases: Kwashiorkor & Marasmus mnemonic.
Kwashiorkor has a lot of O’s
O is a fat alphabet.
That should remind you of fatty liver.
No proteins to send lipids out of liver.
Only protein deficient.
Marasmus has a lot of A’s
A is for appetite.
Ready to eat - which should tell you calories and proteins are deficient in Marasmus.

Dietary sources of essential fatty acids:
“Flowers and nuts contain linoleic acid.
GreeNs and beaNs have an extra N for linolenic acid.”
Sources of linoleic acid are -
Flowers: Safflower oil, sunflower oil
Nuts: Groundnut, coconut.
Sources of linolenic acid are -
Greens: Green leafy vegetables
Beans: Soyabean oil.

Limiting aminoacids:
Cereal proteins (corn, wheat) are deficient in Lysine & Threonine.
I remember the word “CuLT” for this
Random fact: Significant proportions of lysine are found in soyabeans.
Pulse proteins are deficient in Methionine.
Mnemonic: PM

You do not crave certain foods because your “body needs it,” as if a sense of nutritional deficiency is akin to a sense of touch or time. You don’t get a hankerin’ for a cheeseburger because your body is trying to tell you that you need to boost your iron or vitamin D or potassium. 

This is a pervasive myth. 

When you’re actually deficient in any particular nutrient, your body will tell you in a much more extreme way. Instead of daydreaming about your grandma’s biscuits and gravy, you actually get violently, debilitatingly ill whenever you are lacking a vital vitamin or mineral. 

Outside of a literal state of starvation or extreme bodily stress, food cravings are purely psychological. 

Sometimes the psychological effects can be caused by addictive substances in certain foods that cause chemical reactions in the brain, such as the opiates in dairy and the caffeine and other chemicals in chocolate. 

But for the most part, cravings are brought on by complex environmental cues and triggers. They tend to have a lot more to do with nostalgia than nutrition. They are conjured more by an errant scent on the wind than by deficiency. They are more connected to the media you consume than the vitamins you do not. 

Nobody wants to admit that hearing that three second McDonald’s jingle from the receptionist’s radio in the background noise of their dentist’s office is what actually made them determined to pull into the drive-thru on the way home, but it’s certainly far more likely than any pseudo-scientific old wives tale passed around by people who have probably never even met a nutritionist in their life, let alone know anything about nutritional medicine themselves. People want to believe they have more free will than that. They don’t. 

However, through awareness of these things, we can start making more conscious choices about the food we consume.

So the next time someone tells you that humans must eat animal products simply because we crave them, please remember this. 

The identification of Vitamin D Deficiency in Adults from Post-Medieval Sites.

I haven’t been around to do a post on a particular pathology for a while but as I was looking through the International Journal of Paleopathology I came across an article looking at osteomalacia. During my pathology course at Uni we touched on this and therefore thought it would be a good article to focus on. Osteomalacia is a softening of the bones due to a vitamin D deficiency. This is commonly known as rickets children. It is often identified in juveniles by the………. Read More

FOOD FACT: Iron Deficiency

Iron deficiency is the most prevalent form of malnutrition worldwide, affecting an estimated 2 billion people. Eradicating iron deficiency can improve national productivity levels by as much as 20 percent.

(Source:  World Health Organization, WHO Global Database on Anaemia)

To boost the amount of iron in your diet, try these foods:

  • Red meat
  • Egg yolks
  • Dark, leafy greens (spinach, collards)
  • Dried fruit (prunes, raisins)
  • Iron-enriched cereals and grains (check the labels)
  • Mollusks (oysters, clams, scallops)
  • Turkey or chicken giblets
  • Beans, lentils, chick peas and soybeans
  • Liver
  • Artichokes

And here’s a tip: If you eat iron-rich foods along with foods that provide plenty of vitamin C, your body can better absorb the iron.
