Vitamins- Differences, Needs and Supplements

Here are a few ideas and answers on some of the most well known vitamins.....

As consumers, we need to be careful about over consumption of fat soluble vitamins. Fat soluble vitamins are not as easily excreted in the urine or removed from the body as easily as water soluble vitamins. Almost anything we drink can be broken down into H2O… and many foods have water as a by-product from the digestive process. Fat, or lipids, is a very different story. Most individuals tend to try and limit their fat intake in our diet and so if we get fat soluble vitamins through food consumption, but we do not eat enough fat to ‘process’ or consume them then we could not only have the problems of poor absorption – which can cause symptoms of deficiency- but also problems with toxicity as well. Some can be stored in the body in small amounts (mostly in the liver and other fatty tissues.) These vitamins are able to be stored for longer periods of time increasing the chance of toxicity when these vitamins are consumed in excessive amounts. Water soluble vitamins leave the body more quickly and are very little are stored for future use.

A carotenoid is a pigment and the pigment materials that are found in fruits and vegetables- usually the colors range from yellow to orange to red (they can only be found in plant products and some fungus and bacteria- not in animal products with the exception of egg yolks and butter). I think one of the easiest ways to tell if a fruit or vegetable has plenty of carotenoids is to simply look at its color…. Although some green vegetables are high in carotenoids as well. Some examples of high carotenoid foods are asparagus, broccoli, carrots, lettuce, spinach, squash, sweet potatoes, apples, oranges, bananas, peaches, tomatoes and corn.

Vitamin D functions primarily as a hormone- not simply as a vitamin. As a hormone, vitamin D is used to regulate calcium in the blood and the cells of the body as well as bone metabolism. It helps to regulate the absorption of consumed calcium and phosphorus from the intestines and how much calcium is deposited into the bones. My first answer to the question of who needs vitamin D is everyone! My physician told me that anyone she tests tends to be low and needs to take a supplement (we do live in Maine however, which can be a risk factor due to location.) A few risk factors that help a human being to be low in this vitamin/hormone are: skin color (dark skin can block sun exposure), season (northern climates in winter get less direct sun exposure and fewer hours of it), time of day (less direct sun exposure) and age (the ability to get/process vitamin D through the skin becomes more difficult with age.) If you wear sunscreen over 8 SPF than you are also at risk and individuals who spent little time in the sun are very much at risk as most of the vitamin D that our body uses is absorbed through the skin and not from diet.

Vitamin E has a few benefits that are fairly important. As an antioxidant, vitamin E helps form barriers between target molecules and other compounds wishing to ‘steal’ the electrons of the target molecule. The antioxidant will stand between the two compounds and willingly give up some of its electrons or hydrogens to the compound attempting to commit theft and protect the target molecule. Free radicals is the name for some of these compounds that steal electrons. Free radicals have ‘free reign’ when the body doesn’t have enough resources like vitamin E to protect cells. When a free radical steals electrons from other cells, the cell’s DNA is altered and the cell is unable to work the way that it is intended to do so. The cell could be injured or it could simply die. While exposure to free radicals is an essential part of life, exposure to huge amounts is not and doesn’t tend to be healthy.

Individuals who are more likely to have higher physical activity than the general population need a few higher amounts of some vitamins. One of them is vitamin B-6 as this vitamin is needed to process glycogen and protein for full metabolism… and people who engage in more physical activity are more likely to need more protein for energy. Thiamin is also needed in higher quantities for people with higher physical expediency because it helps to break carbohydrates down into energy and also certain amino acids. Folate is especially important for pregnant woman as their body needs the folate, but not enough folate can cause birth defects such as neural tube deficits (and for just general knowledge to women in this class who do not know… when you get your blood work done for your pregnancy and you are told that it is off and you might have a neural tube problem with your fetus…. Take a deep breath and smile- more than 90% of these results are wrong and having a due date that is one or two days off can give you a false positive… as well as a few other things. Yes make sure you are getting what you need especially if you are trying to get pregnant, but don’t stress for days over your blood test until it is confirmed by ultrasound. There is no reason to suffer that way. : )

There are a few reasons that individuals need to take supplements or multi-vitamin pills... but for the most part, the average person gets everything that they need from their diet. That of course depends on whether they are eating a good diet. In the end, I think that one thing I have learned is that the phrase ‘everything in moderation’ is really true. You can have too much of a good thing… and a virtue can become a vice if focused on too intensely. Vitamins and minerals appear to be the same way. One line that really stuck out to me during my readings was that dietary supplements might be necessary if you "don't eat well or consume less than 1,600 calories a day". Supplements can help with not eating well by adding missing nutrients, but I don’t think that supplements can give us good amounts of some things like fiber nor can supplements usually taste good. I would rather enjoy broccoli with a little bit of Ranch than whole foods in a pill. I think that would be so much more enjoyable. : )

What do you think? How do you eat?

Carbohydrates and Fiber - My Personal Analysis :)

So I took the time this week to look at a few things about nutrition. I looked at my fiber content and how much sugar I consumed on my 'recorded' day- as well as total carbs which of which both fiber and sugar qualify. I also took the time to look at why fiber is important in the diet, why we really need carbohydrates in our diets, and why some people are intolerant of milk products.

So when I did 'rate your plate' two weeks ago, I found that I had eaten 233 total grams of carbs. (I also mentioned in a earlier post that I had been low on many important vitamins.) I easily made the RDA of 130 grams of carb intake. (almost doubled it in fact). When I did the math, I found that 52% of my calorie intake was from carbs which was a little less than the 60%- which is the 'goal'. A few ways to improve my intake would be to add more fruit to my diet as well as bread products. I will admit that the bread products are hard because of my allergy to wheat. There are ready made bread products out there for the wheat challenged, but at the risk of sounding like I am complaining- they are expensive! So I try to make the stuff myself as it is a lot cheaper and so maybe I need to find a way to make more... or think of something else...? :)

My fiber consumption I think was pretty good for an American at 29.5 grams... but I still barely made the minimum of 25 grams. Adding more fruit would help with that along with beans. Luckily both are foods that I like and so I just need to really examine and think about how I can change my thought processes and the 'habits' of eating... which I have been working on the last few weeks. I have managed to add more fruit to my diet and I should look at adding more beans. I also want to take the opportunity to do the calculations again after recording a day later this month and see how much better I am doing... or worse ;)

My total sugar intake was 49 grams. That is pretty good, especially since most of that sugar was in fruit that I ate and I can't imagine that I should quit fruit to lower my sugar consumption. I allow myself a few cookies a few days a week and I could look at cutting those out, but I think if I do not feel treated every few days... then I will just crave and crave. Maybe I can look at a couple of cookies and add milk instead of a few cookies with no milk...? Am I making excuses?

Carbohydrates are the body’s main form of energy. As I haven't eaten breakfast yet, I am feeling a little weak and slow, but eating should get me going again. Everything that we do requires energy- breathing, twitching, thinking- even eating requires the expenditure of calories in the work for more calories. Some cells prefer energy from carbohydrates, such as the brain, nervous system, muscles, and red blood cells.... so these areas are directly affected by a low carb diet. If you do not eat enough carbohydrates, the liver is forced to break down protein into energy, a process that over time can affect all of your bodily systems. Carbohydrates are readily acting and fast available fuel for cells- they do not require oxygen to break them down and in most cases are already available as soon as they enter the small intestine.

Fiber is so important for our diets for many reasons! One of the best reasons to eat fiber is so that you do not get constipation. Fiber helps the digestive system keep everything moving and makes it harder for the system to get clogged up. Clogging the system over time cane cause all sorts of complications from cancer to colonic impaction to hemorrhoids from straining to push. Of course, fiber removed the benefit of keeping reading literature in your bathroom as you will not have long to read! :D Some forms of fiber are thought to lower the 'bad' cholesterol in your blood as well as inflammation of the blood vessels- a doctor told me once that he dreams sometimes of little bits of oatmeal acting like scrapers on your blood vessel walls removing plaque- but I have no idea if that is true or his thoughts only... although oatmeal in the store has the heart friendly label on it. Foods that are high in fiber can also help with weight loss and you can feel full without eating as many calories... and fiber pretty much goes 'right through you'. Fiber can help lower blood pressure as well as makes it harder for the body to have 'spiky' blood sugar- sugar is processed more slowly as so would form a mound in measurement, not a peak... does that make any sense. Mounds will help you to eat better because you will not have huge dramatic spikes in your blood sugar which will make you hungry- I guess this is another way of saying that fiber helps with metabolism. Fiber will also act as a scrub brush and try to keep moving impurities and toxins out of the body before they sit and then enter the system. You can thank fiber for helping your child eventually remove the ring or the coin that they swallowed.

Some people are unable to tolerate high milk intake because they are lactose intolerant. Lactose is the sugar found in milk and without the enzyme 'lactase' to break down the sugar, the lactose causing pain, gas and abdominal upset- to say the least. Your risk of lactose intolerance varies depending on your race-and therefore your genes. When looking at large groups Asians, South Americans and Africans are most likely to have this difficulty- the book mentions all of these groups as well. I believe that those of Mediterranean descent are likely to have this problem as well- I heard that in my paramedic classes, but I didn't look to see if my brain was foggy or not before I put that here! Many milk products such as yogurt do not have a lot of lactose and so they can be tolerated by many and used to help provide the calcium needed.

I am really having a pretty fun time studying about how nutrition works... and I hope that some of this information is useful to other readers. Is any of this new to you? How would you rate the way you eat... based on some of the information above? Do you get enough fiber...? Too much sugar...? Please share!
