Beta-Carotene: Vitamin A Activity and More

Vitamin A is essential for growth and development, normal vision, the expression of selected genes, and immunity. But vitamin A deficiency is a major public health problem worldwide, and is the leading preventable cause of blindness among children in developing nations. Vitamin A deficiency also places children at a heightened risk for infectious disease. Even children who are only mildly deficient in vitamin A have a higher incidence of respiratory disease and diarrhea, as well as a higher rate of mortality from infectious disease, compared to children who consume sufficient vitamin A.

Carotenoids comprise a diverse class of antioxidant molecules that help protect the body from oxidative damage. Beta-carotene is one of the best known carotenoids. It is the most abundant in the diet, and it provides significant Vitamin A activity in addition to its role as an antioxidant.

Learn more about the important phytonutrient and how it is related to Vitamin A.

GET TO KNOW YOUR THYROID

The thyroid is a butterfly-shaped gland at the base of your neck. It is aptly referred to as the master metabolism gland. Hormones produced by the thyroid direct calorie consumption, oxygen usage, digestion, the brain and neuromuscular function. So, the thyroid is needed to regulate body temperature, aid in digestion, and enhance cognitive ability. Without the thyroid, our bodies would not be able to convert nutrients into energy.

Thyroid disorders typically fit into one or more of 3 basic categories: iodine deficiency disease, hypothyroidism (under production of thyroid hormone), and hyperthyroidism (over production of thyroid hormone).

Iodine deficiency is the world’s greatest single cause of preventable brain damage and mental retardation.

The total number of people at risk for iodine deficiency disease worldwide in 1995 was 1.5 billion people, or about 29% of the global population. There is little to indicate that it is any better today.

An estimated 20 million Americans have some sort of thyroid disease, and as many as 60% of those with thyroid disease are unaware of their condition.

Women are five to eight times more likely than men to have thyroid problems.
The thyroid secretes important hormones called thyroxine (T4) and triiodothyronine (T3) that are responsible for our overall metabolism and affect nearly every cell in the body. The mineral iodine is essential for the formation of T3 and T4.

Under normal circumstances, about 80% of the thyroid hormones manufactured by the thyroid are in the inactive form of T4. T4 is readily converted to active T3 hormone as needed. The conversion of T4 to T3 takes place primarily in the liver but also in the cells of the muscles, gut, nerves and heart. Healthy liver function is therefore extremely important for optimal production and function of T3.

Brain health is also essential to optimal thyroid function. Stimulated by the neurotransmitter dopamine, the hypothalamus (located in the brain) releases thyroid-stimulating hormone (TSH) that directs the production of T3.

Factors that adversely affect the thyroid include stress, fluctuating reproductive hormones (such as during pregnancy and perimenopause), and environment contaminants such as heavy metals.

Essential nutrients needed to support the thyroid are iodine, zinc, selenium and quality protein, among many others.

If you have concerns regarding nutrient absorption from the diet, protein metabolism, proper digestion, maintaining muscle, cellular energy production, or brain function and cognition, make sure your thyroid has the nutritional support to function properly.

Myth: Raw Vegetables Are Always Better For You than Cooked Ones

The truth about raw vs. cooked vegetables is complicated. It depends on the specific vegetable, the nutrient in question, and your method of cooking.

Nutrients like beta-carotene are more bioavailable from cooked carrots, spinach, mushrooms, asparagus, cabbage, and peppers than from the raw vegetables. But, it is also true that cooking destroys much of the vitamin C and polyphenol content.

Another important carotenoid, lycopene, is also more bioavailable when the food source (i.e. tomato) is cooked. Broccoli is a vegetable that provides more of some healthy nutrients when cooked, and more of different healthy compounds when raw.

So, the answer to whether vegetables are healthier when raw is yes, no, and maybe. And, the best way to ensure you get all the health benefits is to eat the recommended servings of fruits and veggies no matter how they’re prepared. The more ways you make them delicious and inviting to you, the more likely you are to eat them.

Red Blood Cells Carry a Heavy Load

Maintaining a healthy heart and circulatory system requires healthy red blood cells. These hard-working, unique cells deserve some attention. So, here are a few interesting facts that will earn your respect:

• The average red blood cell lives for 120 days. Once mature, red blood cells contain no nucleus or DNA, so they can no longer replicate or repair themselves.
• There are approximately 2.5 trillion red blood cells in your body at any given time. To maintain this number, the body has to produce about 2.5 million red blood cells per second in the bone marrow. That is over 200 billion new red blood cells per day.
• About 5.6 liters of blood circulate through the body three times every minute. That means a red blood cell can circumnavigate your body in less than 20 seconds.
• The largest artery in the body, the aorta, is about the diameter of a garden hose.
• Capillaries, on the other hand, are only 1/10th the diameter of a human hair.
• The human heart creates enough pressure when it pumps to sq**rt blood over 10 meters (30 feet).

Everything you eat and breathe is circulated and delivered to tissues and cells throughout the body. Keep your cells running longer and stronger by providing them all the right fuel, fluids, and nutrients they need
