Edwin, nutrition is a serious matter and it should be a priority for everyone. The idea of ensuring that we get enough nutrition so that our bodies can tend towards a natural state of good health by taking vitamins, minerals, and other supplements is not new, nor is it without merit. There is an old saying "we are what we eat", but this really isn't the whole story. Actually, we are what we ABSORB. In other words, what really matters is what is actually getting into our cells so that our bodies can make use of it. So, the first issue is the quality of foods that we choose to eat. Are they nutrient dense or nutrient poor? The second issue is how well does our body absorb nutrients. The ability to absorb nutrients can be influenced by a person's state of health, genetics, past and current eating habits, and a host of other things.
With respect to food quality, this can be somewhat dealt with by making wiser food choices. Fresh fruits and vegetables, whole grains, and other unprocessed foods are much more nutrient dense. This means that they deliver to our bodies more needed nutrition per calorie than other foods that are less nutrient dense. For example, a carrot is power-packed with Vitamin A, Vitamin K and natural fiber and yet only has about 50 calories. Whereas a pork chop has a high saturated fat content, high cholesterol content, no vitamins/minerals to speak of, no fiber and has about 300 calories. Do you see the difference? Carrots are nutrient dense and pork chops are nutrient poor.
As far as how well our bodies absorb nutrients, well, this can be a little more challenging to compensate for. I would say that the single best approach to improving the ability to absorb nutrients is to just eat more healthy. Just by eating more healthy foods you will improve your ability to absorb nutrients. Nutrient-dense foods promote better absorption, while foods that are processed and filled with a lot of preservatives and added chemical flavorings actually hinder the absorption of many nutrients.
Having said that, the idea of taking good quality vitamins, minerals and other supplements to help ensure that we are getting what our bodies need only makes good sense. Let's face it, our current food supply is not what nature had intended, but that's a whole other topic (LOL). The important thing here is, however, to take GOOD QUALITY supplements. And, by 'good quality' I mean pharmaceutical-grade. There are many supplements (i.e., vitamins, minerals, herbs, etc.) that are cheaply manufactured and so they are of low quality. This is mainly due to added fillers and low-tech manufacturing techniques that produce low quality products. These low quality products will have what is called a "low bioavailability". This means that the body will not be able to properly or completely extract the active ingredient(s). So, first, it's simply a waste of money because your body is not getting what you think you are paying for. Second, since you're not completely getting what you think you are taking, you can't evaluate whether or not it is doing you any good. That would be like taking a cheaply manufactured cholesterol-lowering drug that didn't seem to be lowering your cholesterol. Is it because the drug wasn't effective or is it because you are not really getting the proper amount of the drug? You see, in the U.S., there is no regulation on vitamins and other supplements in terms of manufacturing standards. There are several side issues involved here, but this, too, is a whole other topic (LOL). Let me just say that different manufacturers produce different quality products. And so, just because the bottle says "Vitamin C" on it doesn't mean that the vitamin C in the bottle is of good quality, that is, will have a high bioavailability.
As far the age-related macular degeneration (AMD), there is a lot you can do to help prevent the AMD from getting worse. It would help you to know that there are three main risk areas that are central to AMD. The first is chronic inflammation, the silent asymptomatic type brought on by eating highly processed over-cooked foods (especially animal products). The second is high blood glucose levels. And, the third is poor micro-circulation. Efforts to optimize your health in these ares will go a long way in helping the AMD. Contact me if you want to know more. I'll be glad to tell you what I know.
