Heart of Gold: Turmeric vs. Exercise

Sept 5 Heart of Gold copy.jpeg

The endothelium is the inner lining of our blood vessels. Laid end-to-end, endothelial cells from a single human would wrap more than four times around the world. And it's not just an inert layer; it's highly metabolically active. I've talked before about how sensitive our endothelium is to oxidation (The Power of NO) and inflammation (The Leaky Gut Theory). If we don't take care of it, endothelial dysfunction may set us up for heart disease or a stroke. Are we ready to heed our endothelium's early warning signal?

If it's all about oxidation and inflammation, then fruits and vegetables should help. And indeed it appears they do. Each daily serving of fruits or vegetables was associated with a 6% improvement in endothelial function. These fruit- and vegetable-associated improvements in endothelial function are in contrast to several negative vitamin C pill studies that failed to show a benefit. It can be concluded that the positive findings of the fruit and vegetable study are not just because of any one nutrient in fruits and veggies. Rather than searching for the single magic bullet micronutrient, a more practical approach is likely to consider whole foods. Increasing fruit and vegetable consumption is likely to have numerous benefits due to synergistic effects of the plethora of wonderful nutrients in plants.

Exercise helps our endothelial cells, too, but what type of exercise helps best? Patients were randomized into four groups: aerobic exercise (cycling for an hour a day), resistance training (using weights and elastic bands), both, or neither. The aerobic group kicked butt. The resistance group kicked butt. The aerobic and resistance group kicked butt, too. The only group who didn't kick butt was the group who sat on their butts. Our endothelium doesn't care if we're on a bike or lifting weights, as long as we're getting physical activity regularly. If we stop exercising, our endothelial function plummets.

Antioxidant pills don't help, but drug companies aren't going to give up that easy. They're currently looking into anti-inflammatory pills. After all, there's only so much you can make selling salad. For those who prefer plants to pills, one of the most anti-inflammatory foods is the spice turmeric. Researchers in Japan recently compared the endothelial benefits of exercise to that of curcumin, the yellow pigment in turmeric and curry powder. About a teaspoon a day's worth of turmeric for eight weeks was compared to 30 to 60 minutes of aerobic exercise a day.

Which group improved their endothelial function more? The group who did neither experienced no benefit, but both the exercise and the curcumin groups significantly boosted endothelial function. The researchers reported: "The magnitude of the improvement achieved by curcumin treatment was comparable to that obtained with exercise. Therefore, regular ingestion of curcumin could be a preventive measure against cardiovascular disease" at least in postmenopausal women, who were the subjects of this study. "Furthermore, [their] results suggest that curcumin may be a potential alternative treatment for patients who are unable to exercise."

Ideally, we'd both eat curcumin and exercise. One study looked at central arterial hemodynamics. Basically, if our endothelium is impaired, our arteries stiffen, making it harder for our heart to pump. Compared to placebo, we can drop down the pressure with turmeric curcumin or exercise. However, if we combine both, then we really start rocking and rolling, as you can see in the chart about 4 minutes into my video Heart of Gold: Turmeric vs. Exercise. The researchers conclude that these findings suggest that regular endurance exercise combined with daily curcumin ingestion may reduce the pressure against which our hearts have to figh. We want both healthy eating and exertion for our endothelium.

Vitamin B12 Recommendations

Vitamin B12 Recommendations on a Plant-Based Diet

A plant-based diet has been shown time and time again to be the most health-promoting, disease-fighting, and nutrient-dense way of eating possible. Emphasizing a wide range of vegetables (especially leafy green varieties), fruits, whole grains, legumes, nuts, seeds, herbs, and spices makes it simple to achieve nutrient needs while avoiding chronic overnutrition. Guides such as the Plant-Based Food Guide Pyramid and Plate, 6 Daily 3’s, and Notable Nutrient Chart help with the high level view of what exactly a day-in-the-plant-based-life may look like. As does this post of Everything You Need to Know About A Plant-Based Diet in Less Than 500 Words and Sample Meal Plans Made Simple + Hundreds of Recipes.

One nutrient that likely will fall short on a plant-based diet is cobalamin, commonly referred to as vitamin B12. B12 is produced by microorganisms, bacteria, fungi, and algae, but not by animals or plants. B12 is found in animal products because they concentrate the nutrient after ingesting these microorganisms along with their food in their flesh, organs, and byproducts (e.g. eggs and dairy). Also, ruminant animals (such as cows, sheep, and goats) have bacteria in their rumen that produce vitamin B12.

In a vegan diet, vitamin B12 may be found in fortified plant milks, cereals, and other foods, such as nutritional yeast. However, if vegans are not conscientious about taking in the recommended dietary allowance (RDA), there could be harmful health consequences. Deficiency can result in potentially irreversible neurological disorders, gastrointestinal problems, and megaloblastic anemia. B12 deficiency is not unique to vegans who do not supplement. Deficiency is also a concern with aging, medication use, and gastrointestinal issues. So much so that it has been recommended that all adults over the age of 60 years supplement to avoid deficiency.

Interestingly, the body is able to store B12 for upwards of even ten years. To further complicate this, signs and symptoms for deficiency are either not noticeable or simply very subtle. So, if B12 is not being taken in at adequate levels or if there are absorption problems, deficiency will eventually ensue. Because blood tests for B12 levels can be skewed by other variables, irreversible damage may occur before a deficiency is detected.

RDA’s for vitamin B12 across the lifespan can be found in detail here. For non-pregnant adults, aged 14 and above, the RDA is 2.4 micrograms per day. To ensure this is absorbed (in a healthy individual, barring any possible inhibitors), higher doses are recommended.

B12

 

The bottom line is that it seems the best way to supplement to maximize absorption and maintain optimal blood levels of B12 is for vegan adults (as well as non-vegan adults over the age of 60) should consider supplementing with these doses of vitamin B12:

  • 50 µg twice a day OR
  • 150 µg once a day OR
  • 2,500 µg once a week

High doses of B12 are safe and there isn’t a tolerable upper limit that has been established. It is best to undergo testing regularly and adjust the dose as necessary.

Lasagna

This is very reminiscent of traditional lasagnas, but of course, without the meat, cheese, and added salt and oil. Bottom line: it’s delicious! Instead of meat, I have used zucchini and mushrooms, and a great tofu blend to take the place of the ricotta. Lasagnas are a labor of love, for sure. But they are worth...
