What Causes Poor Health? The Science Of Food

If you think you know how a particular dietary substance can cause poor health, you may be surprised.

People have made it their life’s work to explain food’s origins, which has yielded some interesting results. Many scientists now believe that eating too much or consuming the wrong kinds of food during our early childhood increases the risk that we will develop health issues later in life, and some believe that the foods we eat can actually interfere with our bodies ability to repair themselves.

How Is Eating Bad For You?

One of the reasons for all of this skepticism is that a lack of scientific proof that one food causes another makes it difficult to understand the role it plays in human health.

Here again, the lack of scientific proof is not because there is no such thing as cause and effect. It is a matter of the relative nature of the information that is known in the research arena to produce different results. The question of nutritional causation also poses the question of how you can help a person lose weight and maintain healthy weight over the long haul.

This topic has also been well covered in my prior blog posts, including this one , where you’ll find out about the various nutritional reasons for obesity and how it relates to a lack of exercise. If you’ve been interested in the topic to begin with, you can find more of Dr. Vyvyan’s blogs here and here , and also check out the book The Great Cholesterol Con . Now that you understand the basic science behind this topic, keep learning, you’ve got a great story to tell your grandkids!

Now to the juicy part, the good news:

Nutritional scientists have discovered the key to preventing cancer and other illnesses like heart attacks, strokes, Alzheimer’s, diabetes, and obesity.

Eat more vitamin D

If you’re on a cold, sickly, malnourished diet, you might not be getting the nutrition that you need, especially if you also have low levels of vitamin D. Vitamin D regulates calcium absorption, promotes muscle growth, prevents osteoporosis, regulates immune function, and is required for vision, tooth formation, brain development, and healthy cell division in the reproductive and immune systems. Most Americans have levels of vitamin D that are “excellent” (200-400IU/day) which is in line with what we are supposed to be receiving from sunlight, and some scientists believe that as little as 50-75IU of vitamin D daily may effectively prevent cancer.

So what’s the catch? There isn’t one because there are a number of factors that can influence your vitamin D status which make it difficult to determine what a particular amount should be. You’ll have to do your best to get adequate vitamin A, vitamin K2, vitamin E, and vitamin D3 from food sources but there are also some supplements that are safe, effective in lowering your risk of disease and in reducing your chances of getting diabetes, cancer, and cardiovascular disease.

Vitamin D is found naturally in both fatty marine fish and foods from plant sources. It is the main active vitamin, and is converted to vitamin D3 by the body. In the last three decades, many studies have been done in people to determine the best amounts of vitamin D (200-400 IU per day) and in animals. However, many of these studies haven’t been controlled for disease risk factors, which means it isn’t known how much vitamin D increases the risk of disease in those that don’t already have it.
