Droppin' Mics (Micronutrients - Part I)



Simply Real: Dropping the Mic(ronutrients) Part 1

Something I’ve always thought was funny about so-called “health food” is that there has always been a huge focus on what isn’t in the product: “fat-free”, “low-carb”, “sugar-free”, are all those lovely buzzwords that seem to mean a lot but really mean nothing. I look at food and focus on what is in it. The more good stuff it has, the better! In general, when something is removed from a food something just as bad (sometimes worse) has probably been added to it. Think preservatives, salt, added sugars, and artificial flavors, colors, and sweeteners.
However, a lot of processed foods have vitamins and minerals added to them. What’s really funny about this is that typically, the ingredients in that processed food used to have those vitamins and minerals but – big surprise – they were removed or lost during processing. Just because nutrients are present in food doesn’t mean that the food itself is healthy. Remember our definition of health food!

Also, fun fact: your body actually absorbs and uses natural, food-based vitamins and minerals better than those found in supplements or made synthetically (what’s added to processed foods).

Remember that last week, I discussed macronutrients – the big energy-givers and body-builders. Today, I’m going to discuss the little guys: micronutrients. Micronutrients include vitamins and minerals, which can get really, really not simple. The truth is that the functions of many micronutrients in the body are advanced chemical reactions that take a lot of studying to fully understand (think 3 years of school and 6 chemistry classes…).

Some terms to know that will help you understand what vitamins and minerals do include:

Catabolism: breaking something down into smaller parts
Anabolism: building something bigger out of smaller parts
Metabolism: how the body uses catabolism and anabolism to break down macronutrients and use them to do things in the body.
Electrons: particles which are moved around in the body to use energy
Antioxidant: we need oxygen, but sometimes, extra oxygen floating around can cause reactions called oxidation that produce harmful chemicals. Antioxidants pick up these oxygens and prevent/reduce this from happening.
Free Radicals: the harmful chemicals made when oxidation happens


Some other keys that will be helpful:

Plant-Based foods containing each nutrient are written in GREEN! Because PLANTS.
Key-words that are defined in this post and past posts are bolded.
Otherwise important information is written in RED because it really is important for some people to read these things, and red is eye-catching.
Additional comments that are more or less relevant to the information being discussed is shrunken down so that you can see how unimportant it is – but read them anyways because I think I’m funny.
Vitamin Name
Role in the Body
Why is that important?
Where to find it in food!
B1 (Thiamin)
·         Breaks down macronutrients.
·         Helps with moving electrons to send messages through the nervous system.
·         Allows food to be used for energy
·         Keeps nerves healthy
·         Healthy, working muscles
·         Pork, probably other meats as well, but my textbook didn’t include them because who really needs meat besides tigers and sharks?
·         Sunflower seeds, peanuts, peas, lentils.
B2 (Riboflavin)
·         Breaks down macronutrients
·         Allows food to be used for energy!
·         Beef, dairy milk
·         mushrooms, spinach, almonds
B3 (Niacin)
·         Breaks down macronutrients
·         Builds fatty acids and cholesterol
·         Allows food to be used for energy!
·         Fatty acids are used to build the walls of body cells and keep nerves healthy. They are also how our bodies store fat.
·         Cholesterol helps absorb fat from food. Our bodies also use it to make Vitamin D!
·         Beef, chicken, tuna, all other meats
·         mushrooms, peanuts, broccoli, coffee
B6 (Pyridoxine)
·         Helps make hormones serotonin, norepinephrine, and melatonin
·         These hormones carry messages between nerves.
·         “Mood” and “sleep” hormones.
·         Keeps body’s clock working correctly
·         Beef, salmon
·         Bananas, whole grains, navy beans
B12 (Cobalamin)
·         Metabolism
·         Brain + nervous system health
·         Helps make red blood cells
·         Makes energy from food.
·         Keeps the wrapping around nerves healthy so they can send messages.
·         Blood cells carry oxygen so we can live!
·         Meat, fish, shellfish, dairy
·         IMPORTANT! Vitamin B12 is made by bacteria, and is only naturally present in animal products (fun fact: many of these animals get it from eating their poop, because that’s where the bacteria are making it).
·         Thus, there are no reliable, naturally-occurring sources of B12. So if you are a vegan, be sure to supplement your diet by popping a pill or by choosing an alt-milk that has B12 added to it.
*I personally believe in and practice getting all of my nutrients directly from natural food sources (or as little fortification as possible), which is why I’m not 100% vegan J
Vitamin C
·         Antioxidant
·         Helps build collagen proteins
·         Helps make serotonin and norepinephrine
·         Prevents cell damage caused by oxidation
·         Collagen is what keeps skin soft and stretchy – healthy skin, less wrinkles!
·         The mood/sleep hormones again! Keep us healthy and happy!
·         Liver and organ meats
·         Oranges, bananas, strawberries, kiwis, peppers, cantaloupe.
B5 (Pantothenic Acid)
·         Metabolism
·         Provides energy from food
·         Important for skin and nerve health
·         Liver, beef, chicken, fish, egg yolks
·         Beans, peas, peanuts, avocados
Biotin
·         Metabolism
·         Builds fatty acids
·         Build amino acids
·         Provides energy from food
·         Fatty acids are stored or used for cell health.
·         Amino acids are used to keep hair and fingernails healthy.
·         Made by bacteria and used by the body, but we still need some from food!
·         Egg yolk, liver
·         Soy beans, peanuts, beans, lentils, nuts


Fat Soluble Vitamins
·         Absorbed with fat!
·         Stored in the body, so they can be toxic.
·         Just get them from food. Don’t mega-dose yourself.
Role in the Body
Why is that Important?
Where to find it in food!
Vitamin A (Retinol)
·         Makes pigments and light receptors in eyes.
·         Getting a little complicated here: interacts with DNA to change cells.
·         Builds bones
·         Immune health
·         Light receptors are what allow us to see! Healthy receptors = healthy eyes
·         So in all honesty, really not super-important to know, but I was proud of the analogy here, and it’s pretty interesting. Think of it like a guidance counselor for cells: it helps little high school skin cells go to college to become epidermis cells (your “skin”), rather than the slimy under-ground-dwelling mucus-making cells. And vice-versa.
·         Works with bone cells (no one really knows how it works, actually)

·         Liver, dairy
·         Carrots, sweet potatoes, butternut squash, pretty much all of my favorite vegetables ever, greens, broccoli, yup.
Vitamin D
·         Bone metabolism
·         Maintains healthy levels of calcium in the blood
·         Cellular health
·         Super simple here: helps build bones and keeps them healthy by working with calcium – which we’ll learn more about next week cause this is turning out to be quite the info dump J
·         Works much like Vitamin A on cells, but in the intestines and some blood cells.
·         Our bodies make it – and can make plenty of it with just 15-30 minutes of sunshine every day!
·         Dairy (usually fortified), salmon, egg yolks
·         Alt-milks (usually fortified), mushrooms but really, how great are mushrooms? Bet you didn’t know they were so great, huh?
Vitamin E

·         Antioxidant
·         Helps prevent free radicals, those nasty little things that can cause damage to cells.
·          
·         Salmon, egg yolks, codfish
·         Olive oil, other vegetable oils, nuts and seeds
Vitamin K
·         Blood clotting
·         Needed for proteins involved with bone health

·         Activates proteins which bind to calcium and other things floating around in the blood to help it clot if you happen to cut the tip of your finger off while making salsa (this has happened to me more than once).
·         Again, vitamin K activates proteins which help rebuild bone.
·         Vitamin K is produced in plentiful amounts in our guts! Thanks, bacteria!
·         But you can also get it from foods… Anything green and leafy (kale, spinach, lettuce, cilantro, parsley, beet greens, collard greens, etc.), broccoli, cauliflower.
·         IMPORTANT!!! People who are taking blood thinners need to watch their vitamin K intake. Your doctor should have told you this, and you should be going to regular blood draws and checkups to monitor this J

Well, this turned out to be quite a lot more information than I intended! As I stated before, micronutrients are complex – there’s a lot that goes into understanding exactly what they do, and I’ve tried my best to simplify things and tell you what’s really important to know. Though it may not be super important, I like to include why these things are “good for your eyes”, or “help build strong bones” so that you’re informed. Anyone can tell you anything (usually to sell your something) – like the people who say B Vitamins energize you. But as you learned today, that ain’t true! It’s the calories from the food (macronutrients) we eat that provide us with energy, the B vitamins simply help our bodies use the energy that’s already there.
 There’s a lot more that goes into it than what I’ve described, and if you’re up to it, I totally encourage you to investigate and learn more about how vitamins work in our bodies! It’s truly amazing to literally see how we were created with such tiny, tiny details that work together so perfectly. In the next post, get excited for minerals, the other micronutrients!

I promise, we’re almost through with the science-y stuff (hah, never!) and on to what you all really want to know… how to cook healthy food!
