What are the best sources of iodine?


People who enjoy eating seafood on a near-daily basis have a good chance of meeting their daily iodine needs because they will often be able to get 50% of more of those needs from the seafood alone. A single serving of dairy foods on the same day might move this percentage up closer to 75%, and other foods would be able to make up the remainder.
For people who completely avoid seafood in their meal plan, iodine needs become a little bit trickier to meet.

Bromelain in Pineapple

Bromelain is a complex mixture of substances that can be extracted from the stem and core fruit of the pineapple. Among dozens of components known to exist in this crude extract, the best studied components are a group of protein-digesting enzymes (called cysteine proteinases). Originally, researchers believed that these enzymes provided the key health benefits found in bromelain, a popular dietary supplement containing these pineapple extracts.

What if I Eat Vegetarian Most of the Time, but Enjoy Meat and Poultry on Occasion?

Vegetarian Diet


Would you be classified as a vegetarian in a research study if you enjoyed meat and poultry on occasion? No, you would not. You would be classified as "semi-vegetarian."
But much more importantly, what about the health consequences of enjoying meat and poultry on occasion? Would you still get the same health benefits as a vegetarian? What the research shows in this regard is similar health benefits for semi-vegetarians as compared with lacto-ovo vegetarians (consuming dairy, eggs, and plant foods) and pesco-vegetarians (consuming seafood and plant foods). In comparison to non-vegetarians, these groups have been shown to receive health benefits from their eating approach.

Why is there so much controversy about soybeans?

Soybean Products


Given the fact that soybeans are a food that has been enjoyed by millions of people over thousands of year, it's unexpected to find so much controversy surrounding this legume. And yet in the public press and in scientific research, soybeans have been a topic of ongoing controversy. For example, in 1999, the U.S. Food and Drug Administration (FDA) authorized a health claim for soy protein as a nutrient that could reduce risk of heart disease. And yet in 2007, numerous scientists in the U.S.officially asked the FDA to revoke its heart-related health claim for soy protein.

We suspect that one basic factor accounts for most of the controversy that has surrounded soy and its role in a healthy diet. This factor is what we would summarize as "east versus west." Soybeans were adopted as important parts of the diet in China (and then later in Japan and Korea) long before they became part of European or North American diets. Culinary traditions involving soy have existed for dozens of generations across Asia, but remain almost non-existent even today in Western countries like the United States. When research is conducted on the health benefits of soybean in Asian diets, the findings seldom match up with research findings on U.S. and European populations.

What is the role of vitamin D in bone health?

Food High in Vitamin D

Vitamin D deficiency can lead to softening or malformation of bone. In children, this condition is called rickets. In adults, it is called osteomalacia.The relationship between vitamin D and bone metabolism is more complicated than you might guess. As a hormone, vitamin D acts to increase calcium in the blood stream. The first two ways it accomplishes this are by increasing your ability to absorb calcium from foods and by reducing the amount of calcium you lose in the urine.

How can you increase health benefits from garlic?


You can increase the health benefits you receive from garlic by letting it sit after you've chopped it or crushed it. If you give your chopped/crushed garlic time to sit before changing its temperature (through cooking) or its pH (through the addition of acidic food like lemon juice), it will give the alliinase enzymes in garlic an opportunity to work on behalf of your health.

What are the betalains found in beets?


Beets are a unique source of phytonutrients called betalains. Betanin and vulgaxanthin are the two best-studied betalains from beets, and both have been shown to provide antioxidant, anti-inflammatory, and detoxification support. The detox support provided by betalains includes support of some especially important Phase 2 detox steps involving glutathione.

How does the selenium in tuna help lower the risk of mercury-related problems?

Researchers have recently discovered that tuna contains the mineral selenium in an unusual form called selenoneine. This form of selenium plays an important role in the health of the fish by serving as an antioxidant and protecting the fish's red blood cells from free radical damage. Interestingly, it is also able to bind together with mercury compounds in the fish's body (including methyl mercury, or MeHg) and lower their risk of mercury-related problems.

More about the phytonutrients found in onions?


The flavonoids in onion tend to be more concentrated in the outer layers of the flesh. To maximize your health benefits, peel off as little of the fleshy, edible portion as possible when removing the onion's outermost paper layer. Even a small amount of "overpeeling" can result in unwanted loss of flavonoids. For example, a red onion can lose about 20% of its quercetin and almost 75% of its anthocyanins if it is "overpeeled."The total polyphenol content of onions is much higher than many people expect

How is phosphorus involved in cell structure and function?


Biologists who study the nature of living things typically regard the cell as the smallest functional unit of life. From single cell bacteria up through the tens of trillions of cells that make up our bodies, the structures of a cell are fairly consistent from organism to organism.Perhaps the most defining characteristic of a cell is its outermost membrane, simply called the "cell membrane" (or sometimes the "plasma membrane"). The cell's outer membrane acts as a mediator between its internal space and everything that takes place outside of it.

What are some of the nutritional benefits of summer squash such as zucchini?


Although summer squash has long been recognized as an important food source of carotenoids, only recently have research studies documented just how fantastic summer squash can be when it comes to these key antioxidants. When we think about food and antioxidants, what first comes to mind might be fresh fruit and vitamin C, or bright orange carrots and beta-carotene. Yet several recent studies have underscored the unique contribution made by summer squash to our antioxidant requirements. While not as rich in some of the more widely-publicized antioxidants like beta-carotene, summer squash is a very strong source of other key antioxidant nutrients, including the carotenoids lutein and zeaxanthin. Since the skin of this food is particularly antioxidant-rich, it's worth leaving the skin intact and purchasing organic summer squash to help avoid potential unwanted contaminants.

How much of a problem is protein in a vegetarian diet?


As a general rule, high-quality vegetarian diets—regardless of type (i.e., lacto-ovo vegetarian, pesco-vegetarian, or vegan) —can provide ample amounts of protein as well as a good balance of amino acids. However, ample protein intake is not automatically guaranteed on a vegetarian diet, and this lack of a guarantee is reflected in research results from the National Health and Nutrition Examination Survey (NHANES) from 2003-2010.

Is eggplant a good source of antioxidants?


Researchers at the US Agricultural Service in Beltsville, Maryland, have found that eggplants are rich sources of phenolic compounds that function as antioxidants. Plants form such compounds to protect themselves against oxidative stress from exposure to the elements, as well as from infection by bacteria and fungi.
The good news concerning eggplant is that the predominant phenolic compound found in all varieties tested is chlorogenic acid, which is one of the most potent free radical scavengers found in plant tissues.

Is cod a good choice for cardiovascular health?

Fish, particularly cold water fish like cod, have been shown to be very beneficial for people with atherosclerosis and diabetic heart disease. Studies show that people who eat fish regularly have a much lower risk of heart disease and heart attack than people who don't consume fish. Cod, specifically, promotes cardiovascular health because it is a good source of blood-thinning omega-3 fatty acids as well as an excellent source of vitamin B12 and a good source of vitamin B6, both of which are needed to keep homocysteine levels low.

What is the certification process in a food becoming certified organic?

Certification standards establish the requirements that organic production and handling operations must meet to become accredited by USDA-accredited certifying agents. The information that an applicant must submit to the certifying agent includes the applicant's organic system plan. This plan describes (among other things) practices and substances used in production, record keeping procedures, and practices to prevent commingling of organic and non-organic products.
