It’s not just that they didn’t eat Twinkies and Cheetos.
Hunter-gatherers ate a wide variety of fruits, vegetables, roots, beans, nuts, tubers, pollen and even flowers rich in antioxidants, phytochemicals, vitamins, minerals and dietary fibre. Some researchers believe that the early humans ate up to 100 different varieties of plants and it’s estimated that their vitamin C intake was about 600mg per day (about 10 times more than the present-day recommended intake). Also, the meat that formed part of the palaeontological diet differed from modern meat because it was low in fat and cholesterol.
In contrast, The everyday diets we follow are much more monotonous and restricted than those of our forefathers. Modern diets are high in energy, low in micronutrients, high in fat and sugar, have a high GI and a low fibre content.
Considering our genetic makeup hasn’t changed much in that time, it’s no wonder so many of us are sick!
Negative effects of plastics additive blocked by supplemental folic acid

Epigenetics is a term referring to changes in gene expression which do not result in changes to the gene itself. Research in animals has shown that what a pregnant mother eats can alter the expression of genes in her offspring, making them more susceptible to certain diseases later in life.
In their most recent experiments, Duke University Medical Center investigators demonstrated that exposure within the womb to bisphenol A (BPA), an ubiquitous chemical used in the production of plastics, caused noticeable changes in the offspring without altering any of the offspring’s genes. Additionally, the researchers discovered that administration of folic acid or genistein, an active ingredient in soy, during pregnancy protected the offspring from the negative effects of BPA.

compounds found in plants that are not required for normal functioning of the body but that nonetheless have a beneficial effect on health or an active role in the amelioration of disease. Thus, they differ from what are traditionally termed nutrients in that they are not a necessity for normal metabolism, and their absence will not result in a deficiency disease. What is beyond dispute is that phytonutrients have many and various beneficial health effects. For example, they may promote the function of the immune system, act directly against bacteria and viruses, reduce inflammation, and may also be associated with the treatment and/or prevention of cancer (the focus of this article), cardiovascular disease and any other malady affecting the health or well-being of an individual.
Read about the specific phytonutrients found in different foods and their beneficial properties.

A recent study in the American Journal of Clinical Nutrition has shown that over 55% of healthy children — up to 68% in winter — have low levels of Vitamin D, putting them at risk for weakened bones and serious disease.
More than 90 percent of African-American children tested had low blood levels of vitamin D, and about a fifth had levels associated with rickets and other diseases of the bones or muscles.
Vitamin D is needed by the immune system, and a deficiency can lead to poor absorption of bone minerals and may contribute to cancer, multiple sclerosis, hypertension and type 1 diabetes.

Researchers in India say that the mango peel is a good source of antioxidants, rich in anthocyanins, carotenoids and polyphenols.
Of course, the peel is a little hard to digest. No problem. An extract from the peel is made with acetone. This makes the process of extraction extremely cheap, and cuts down on waste.
Now if they can just figure out a way to utilize that enormouse pit, I’ll really feel like I’m getting my money’s worth.

Just when you think you’ve got the final word on something…
A few days ago, I posted on the latest research on Vitamin C, which concluded that it didn’t really help the average person with colds.
Executive Director of Alliance for Natural Health Dr Robert Verkerk says: “These headlines have been triggered by a small update to an existing review that does not reflect any significant new research findings.”
The alliance argue that the Cochrane review has a number of fundamental flaws.
They say it looked at a poor range of vitamin C doses, participants did not take the supplement often enough and incompatible trials were pooled together.

We all know someone — perhaps even the person smiling back from the mirror at us — who will swear as to the efficacy of Vitamin C as an immune system enhancer. Of course, they don’t really need to swear, because “everybody knows” that Vitamin C is good for preventing and healing from colds. Everyone except researchers, that is.
The researchers, from the Australian National University and the University of Helsinki, focused on research where participants were taking daily vitamin C supplements.
But their conclusion appears to suggest that the idea vitamin C supplements fight off colds is a myth. They found that only individuals under extreme physical stress, such as athletes and soldiers, stood to benefit.

Of course, colds aren’t the only reasons for taking Vitamin C. Let’s not forget about scurvy, and of course it is used daily in the body in a range of metabolic reactions. The researchers do acknowledge that taken in combination with other ingredients, such as echinacea, it may have unknown health benefits.

Filed under the category of “Fringe News”, here are two of the odder news stories I came across today:
Larry Thrasher’. of Hartselle, Alabama, recently brought 66,000 packets of nutritional supplements to the Alabama National Guard units stationed in Iraq. He has implored several surrounding churches, businesses and individuals to help with his crusade to bring much-needed nutritional drinks to troops in Baghdad. Read more.
Psychologist Dan Gilbert challenges the idea that we’ll be miserable if we don’t get what we want. Our “psychological immune system” lets us feel real, enduring happiness, he says, even when things don’t go as planned. He calls this kind of happiness “synthetic happiness,” and he says it’s “every bit as real and enduring as the kind of happiness you stumble upon when you get exactly what you were aiming for.” Watch the video.
(But actually, these are both pretty interesting!)

Sugar free. Caffeine free. Transfat free. And now, ladies and gentlemen, “China-Free”. Hardly a natural progression, I know, but it is here, nonetheless.
You’ve no doubt heard by now the almost weekly reports of contaminated products, from toothpaste to dog food, coming out of China. And to assuage your fears…
A U.S. health food company will label its products “China-Free”.
Food for Health International, based in Orem, Utah, makes whole food nutritional supplements for people and pets, and President Frank Davis said the company will begin trumpeting the fact none of its ingredients come from China.
Plans call for a “China-Free” sticker on products such as Food for Health’s “9 a Day-Plus” capsules, “Active Adults” whole food shakes and “Healthy Dog” supplements. The company also will use “China-Free” in advertisements and promotions. Read more.
