Researchers: Eating organic provides much greater nutritional intake vs. conventional foods

Despite propaganda put out by the pesticide and genetically modified organism (GMO) industries, the evidence is clear: organic food has a higher nutrient content than food produced with GMOs and synthetic pesticides and fertilizers.

The issue is only increasing in relevance as consumers continue to turn to organic rather than conventionally produced foods. From 2014 to 2015, the amount consumers spent on packaged organic products went from $12.8 billion to $13.4 billion. That doesn’t include sales of organic produce, bulk dried goods, meat, or meals at organic restaurants.

Yet you’ll still hear certain scientists, along with pesticide and GMO company spokespeople, claim that organic food is no better for you than “conventional” food. What’s the truth? (RELATED: Discover more news about healthful vs. harmful food ingredients at Ingredients.news)

Dramatically higher antioxidant content

The evidence for organic foods’ superior nutrient content just keeps getting stronger. In 2011, the journal Critical Reviews in Plant Sciences published what was, at that time, one of the most sophisticated analyses of the prior research comparing nutrient content of organic and conventional foods. They found that in general, organic foods tend to be higher in antioxidants (including vitamin C) and phenolic acids, but may be lower in protein and vitamin A.

They hypothesized that the main difference between the foods is the excessive use of synthetic fertilizers in conventional agriculture, which adds much more nitrogen to the plants’ diets. This leads to a reduction in stress, causing the plants to produce fewer defense-related secondary metabolites, such as vitamin C and other antioxidants. But it may cause the plant to accumulate more nitrogen in the form of protein, and to increase the content of secondary metabolites unrelated to defense, like vitamin A.

The researchers found that the levels of secondary plant metabolite-based nutrients in organic fruits and vegetables were about 12 percent higher in organic than in non-organic produce. Defense-related secondary metabolites in particular were 16 percent higher.

“This subset encompasses most of the important, plant-based antioxidants that promote good health,” the researchers wrote.

In 2014, an even more comprehensive analysis reviewed the findings of 343 prior peer-reviewed studies on the same topic. This paper, published in the British Journal of Nutrition, was the largest such analysis ever performed.

The researchers found much stronger results than the analysis from three years prior. They found that the antioxidant content of organic fruits and vegetable was between 19 and a shocking 69 percent higher than that of non-organic produce. This difference was large enough that shifting to an all-organic diet could provide the same nutritional benefit as eating an extra two servings of fruits and vegetables daily.

Organic food lower in poisons

Higher nutrient content isn’t the only reason that organic food is better for your health, of course. Organic food is guaranteed free of GMOs, which have been linked to organ and reproductive problems.

It is also free from the residue of dangerous pesticides that have also been linked to problems across the health spectrum.

According a study published in the journal Environmental Research, switching to an organic diet can reduce an adult’s overall pesticide exposure by 90 percent. Another study, published in Environmental Health Perspectives, showed the same effect over the long-term. It found that study participants who reported eating a higher proportion of organic produce showed evidence of significantly less organophosphate pesticide exposure than participants who ate mostly conventional produce.

This translates into real health benefits. According to a letter published in the Annals of Internal Medicine, you can reduce your pesticide-related health risk by 94 percent just by eating only organic forms of the top six most pesticide-intensive fruits (currently strawberries, apples, nectarines, peaches, grapes and cherries).

Despite the growing popularity and increasingly strong case for organic foods, farmers have been slow to convert their farmland to organic production. Several major food companies are now offering monetary incentives to help farmers make the switch.

vitamin c

Researchers found that using vitamin C correctly in high doses kills cancer cells

One of the greatest controversies in oncology may have been resolved: Researchers may have discovered the reason that research into the effectiveness of high-dose vitamin C as a cancer treatment has been so mixed.

When taken orally, massive quantities of vitamin C are either broken down or excreted unused by the body. In contrast, intravenous administration of vitamin C produces blood levels 100 to 500 times higher than oral administration.

This could explain why many clinical trials on vitamin C and cancer — most of which have used oral administration — failed to support the results seen in laboratory studies using cancer cells.

Surprisingly, the most recent study on the topic from researchers at the University of Iowa (UI), published in the journal Redox Biology, suggests that vitamin C’s cancer-fighting potential might come not from its antioxidant capabilities, as previously assumed. On the contrary, vitamin C appears to generate free radicals that tear apart cancer cells while leaving healthy cells unharmed.

Targeting a weakness of cancer cells

In prior research, the same scientists found that high-dose vitamin C selectively killed cancer cells in the laboratory, and had the same effect in mice … if the vitamin C was administered intravenously. In the new study, researchers sought to discover the causes behind this effect.

They found that in the body, vitamin C quickly breaks down, generating the free radical hydrogen peroxide as a byproduct. This is a paradoxical effect, because free radicals are the very cell- and DNA-damaging chemicals that antioxidants such as vitamin C remove from the body.

But the researchers further found that healthy cells seemed to have defensive mechanisms that easily allowed them to resist the oxidizing effects of hydrogen peroxide (hydrogen peroxide is, in fact, used as a defense mechanism by the body’s own immune system). Tumor cells, however, were much more likely to be damaged and destroyed by the chemical.

“In this paper we demonstrate that cancer cells are much less efficient in removing hydrogen peroxide than normal cells. Thus, cancer cells are much more prone to damage and death from a high amount of hydrogen peroxide,” lead researcher Garry Buettner said.

“This explains how the very, very high levels of vitamin C used in our clinical trials do not affect normal tissue, but can be damaging to tumor tissue.”

Treatment on the horizon?

The researchers found that healthy cells use various mechanisms to remove hydrogen peroxide, and that one of the primary mechanisms is the enzyme catalase. They found that the lower cells’ catalase activity, the more damage they suffered from hydrogen peroxide exposure.

“Our results suggest that cancers with low levels of catalase are likely to be the most responsive to high-dose vitamin C therapy, whereas cancers with relatively high levels of catalase may be the least responsive,” Buettner said.

The researchers are planning future research to develop ways to measure tumors’ catalase levels and test this hypothesis further.

UI researchers also conducted clinical trials using intravenous, high-dose vitamin C in patients with pancreatic and lung cancer. Earlier, smaller trials suggested that this treatment had limited side effects and might improve patient outcomes. The larger study hopes to establish whether vitamin C, in conjunction with other cancer treatments, actually boosts patient survival.

Research continues to uncover new and surprising mechanisms by which vitamin C attacks cancer cells. A 2007 study by researchers from Johns Hopkins University found that many tumor cells rely on a protein known as HIF-1 for their survival, which allows them to continue growing in the absence of oxygen — which cancer cells tend to use up through their out-of-control reproduction. But HIF-1 only functions in high concentrations of free radicals, which vitamin C removes.

A 2015 study published in the journal Science found that in colorectal cancer cells with particular cell growth-related mutations, vitamin C induces oxidative stress and shuts down an enzyme that the cells use for reproduction. This finding was particularly promising, since cancer cells with this mutation are almost entirely immune to chemotherapy.

Editor’s note: We strongly recommend sourcing non-GMO vitamin C where possible. Most vitamin C is currently made from GMO corn. Very few providers currently offer non-GMO vitamin C.

superfood

A year-end look at superfoods: What’s good, bad and just odd

Over the past few years, the term ‘superfood’ has become a popular buzzword in the food and health language. We all know that an active lifestyle combined with a balanced diet packed with fresh, organic fruits and vegetables remains the best way to ensure optimal health. However, some foods are so nutrient dense that they stand out from the rest.

These super nutrient-dense foods are loaded with vitamins, minerals, fiber, antioxidants, and other health-boosting phytonutrients. When we think of superfoods things such as kale, blueberries, chia seeds, and goji berries immediately spring to mind. While these are touted for their super powers, every year new contenders that offer a tremendous dietary and healing potential are added to the superfood list.

The superfood fad is set to continue in 2017, so here are the past year’s trendiest health foods that will carry their superfood status into the new year.

1.      Chlorophyll

Chlorophyll is the green plant pigment crucial for the process of photosynthesis. It pulls in light rays from the sun and converts them to energy. Besides sustaining plant life, it turns out adding chlorophyll to your yogurt bowl, water, or cold-pressed juice has some tremendous effects on human health too.

Chlorophyll is an excellent liver detoxifier that promotes energy, mental clarity, and weight loss. Furthermore, it has been shown to bind and eliminate environmental pollutants including toxic heavy metals, pollution, and certain carcinogens.

2.      Activated charcoal

While this chalky substance has been used for ages to treat poisonings and drug overdoses, activated charcoal in lemonades and hangover pills seem to be a growing trend. However, Vogue warns that regular use may not be such a great idea because it can interfere with the absorption of other vital nutrients.

3.      Maple water

Introduced as the alternative to coconut water, maple water stimulates the immune system and is loaded with abscisic acid (ABA), which helps move sugar out of the bloodstream. However, critics are not sure if this trend will still stand in 2017 as it has less flavor, fewer electrolytes, and is more expensive than coconut water.

4.      Bone broth

Celebrities like Salma Hayek and Gwyneth Paltrow swear by it. Bone broth is rich in collagen, glutamine, glycine, and proline, all essential to muscle and ligament function and repair. Furthermore, the collagen has also been shown to reduce intestinal inflammation for a healthier gut.

5.      Almond butter

According to researchers at the Harvard Medical School, a diet containing nuts can contribute to lessening the risk of heart disease, diabetes, and stroke. This overly delicious snack is believed to grow in popularity within the next year.

6.      Banana flour

While you might not have heard of banana flour yet, it is on its way to rocking the superfood world. This gluten-free flour is an excellent prebiotic that promotes the growth of healthy bacteria in the gut, which boost immunity and weight loss and improve overall health.

7.      Acai bowls

If you haven’t seen an acai bowl passing by on Instagram, then you’ve probably lived under a rock for the greater part of 2016. Acai berries are the superstars when it comes to antioxidants that fight inflammation, lower oxidative stress, and promote brain health. Furthermore, they are packed with fibers and heart-healthy fats.

8.      Kefir

In 2016, a lot of attention has gone to our gut health and pre- and probiotics. While many cultures have been drinking the fermented dairy beverage for centuries, the West has now jumped on the kefir bandwagon and has called it a superfood.

9.      Turmeric

Turmeric is one of the most revered spices in traditional Chinese and Indian medicine. Recently, word of turmeric’s powers has spread through the rest of the world. It works wonders in the treatment of chronic inflammation and has been linked to reducing the risk of breast, prostate, lung, and colon cancer.

10. LaCroix

Since the 1990s, LaCroix’s sugar-free seltzer water has been a favorite amongst Midwestern mothers. As more influential and famous people openly began popping cans of LaCroix’s sparkling water as a healthy alternative to soda, it has massively grown in popularity.
