Vegan For The Health Of It?

I’ve been resisting the urge to write about last week’s big news story concerning meat and mortality. The study made a case against high intakes of meat and got lots of press. It reinforced the idea that red meat is bad for us, so that’s a good thing for anyone who promotes a plant-based diet.

Like all epidemiologic studies, it had its share of weaknesses, but the large number of subjects helps to counteract some of that. Furthermore, the results are supported to some extent by other research about the dangers associated with red meat consumption. […]

Preventing Prostate Cancer with Diet

Although prostate cancer is the most common cancer among U.S. men, there is good news about the potential for prevention. It’s a slow-growing cancer, typically diagnosed at older ages. Therefore, anything that can slow the growth of these tumors can have a big effect on survival.

For example, research shows that men in Japan are just as likely to have prostate tumors as western men—but far less likely to die from this cancer. One theory is that certain diet or lifestyle factors may slow tumor growth so much that the men die of old age before the […]

Soy and Sperm (and Testosterone, Too!)

The problem with soy is that it is a hugely hot area of research—more than 10,000 scientific papers have been published within just the last decade alone on soyfoods and health. With that level of investigation, there will always be a few studies here and there that show scary findings. By pouncing on those findings—rather than looking at what the majority of the research shows—critics can build a case against soy that sounds credible, even when it isn’t.

Soyfoods are an essentially unique source of isoflavones—which are a type of phytoestrogen, or plant estrogen. So it’s not surprising […]

Feed Your Daughters Well

It still isn’t clear that what we eat as adults will impact our risk for cancer. But there is lots of evidence that what girls eat—especially during puberty—can affect their risk of getting breast cancer in adulthood. The theory is that certain compounds in food impact breast tissue as that tissue is developing, either conferring lifelong protection against cancer or raising risk for cancer.

I wrote several months ago about soyfood consumption during the teen years and how it can protect against breast cancer in adulthood. More recently, Harvard researchers looked at the effect of red meat […]

Soyfoods for Young Girls Offer Lifelong Protection

My friend Kate recently asked what I thought about the fact that her granddaughter drinks a lot of soymilk. I said I thought it was great!

There are plenty of reasons—mostly from ethical and environmental standpoints—to avoid cow’s milk. Whether there are important health risks associated with dairy consumption is still a question of debate. But there is little to suggest that dairy has any protective benefits that you can’t get elsewhere. Soy, on the other hand, may have some unique and long-lasting benefits for young girls.

Interest in a cancer-protective effect of soyfoods comes, in part, from […]

Soyfoods, Iodine and Thyroid Function in Vegans

Many foods—including soy, broccoli, and millet—contain goitrogens, which are compounds that interfere with thyroid function. Most people can eat these foods regularly without problems. Problems do occur in people who have low intakes of the mineral iodine, which is needed for a healthy thyroid.

In the 1950s approximately 10 cases of goiter—a symptom of thyroid problems—were identified in infants consuming soy infant formula. These 50-year-old studies have been used to fuel arguments that soy is dangerous for infants—but in fact, they have no relevance to infants who are currently fed soy infant formula. Today’s formula is fortified with […]

The Mediterranean Vegan

Low-fat diets are sometimes touted as the healthiest way to eat, but that’s an old-fashioned idea. It’s also bad activism on behalf of vegan diets. Even people who are strongly motivated often find it difficult to eliminate animal products from their diet. So why make it harder with additional restrictions on fat?

A Mediterranean-style vegan diet is one that is likely to appeal to many more people than a low fat regimen. It offers a chance to eat healthfully, humanely, and deliciously. Mediterranean diets are based on grains like pasta, rice and bread, fresh vegetables and fruits, and […]
