When it comes to sugar substitutes, what about stevia?

Blue, pink, yellow? d) None of the above

Yesterday, The New York Times ran a story entitled “Choosing a Sugar Substitute”. I found the article, like most sweeteners, unsatisfying. We’re told “for any of the sweeteners, one can as easily find a study that offers reassuring analysis of safety as one that enumerates potential alarming side effects.” When it comes to food and nutrition this “jury is still out” reasoning doesn’t work. As far as I’m concerned, the risky results have more clout. The article further tries to ameliorate potential risk by quoting a layperson and self-described “yellow girl” (yellow referring to Splenda affection) saying “hundreds of millions of people swallow food and drinks containing artificial sweeteners and so far, no widespread calamities of health have swept over them. “ I would love to know if yellow girl feels migraines, obesity and cancer are "widespread" enough. I don’t know if she equates danger with immediate death but we’re not talking about snake bites. With toxins, things can take time. Walter Willet expressed “if you smoke cigarettes, the lung cancer risk doesn’t go up for 30 years.”  Trans fats weren’t seen as problematic for 90 years. You can read my thoughts on artificial sweeteners here in “Better Safe Than Sweet”

The best way to test a sweetener isn’t always research, where funding can introduce its own bias, but time. Sugar has been used long enough that we know the downside and concerns. Stevia has also been used for centuries in many cultures though only marketed (and approved) in the US recently. I was disappointed the Times article snubbed stevia. It is a plant you can grow in your garden. Detractors will say, “Just because it’s natural doesn’t mean it’s safe” and this is true but I’ll still take the garden over the lab as a starting point.  I love a brand called NuNaturals, which has no stevia-y aftertaste but also have this local honey and maple syrup in my home. Liquid stevia can seems rather pricy but a small bottle can last months, even a year because it’s much sweeter than sugar. Since it’s much sweeter than sugar, you use it sparingly.

Even the title of the Times piece rubbed me the wrong way. Sweeteners aren’t mandatory. Whether it’s honey or maple or stevia, I don’t believe our food should be doused with sweetness. Sweet begets sweet and the more you have the more you crave. The converse is also true and less sweetness leads to fewer cravings. One “sweetened” item a day is a good guideline. For me, that tends to be my smoothie or an afternoon cardamom cappuccino. So I'm not a blue, pink or yellow girl and truthfully I'm not that sweet.

What sweetener(s) do you use? How many sweetened foods would you estimate you have each day? Have you tried stevia? 

Boston (but no marathon)

Thank you for those who tweeted "are you running?" Um no.

I’m in Boston for Dr Weil’s Nutrition and Health Conference. This is a conference I look forward to and have attended twice before in New York and also San Diego. Presenters, at any event,  are always a mixed bag and sometimes the sessions you expect to be best are not the highlights. Dr Robert Lustig opened the morning yesterday. His name may sound familiar as he figured prominently in 60 Minutes sugar segment; he’s also the endocrinologist quoted in the NYT early puberty article. Dr Lustig presented on fructose. I was really excited but not for the biochemistry lesson he started in with. There were two fun facts, after 45 minutes, first that 80% (wow) of supermarket items have some sugar. And second, Lustig’s “4 foods of the apocalypse”

Trans fats

Corn Fed Beef

Ethanol (alcohol)

Fructose

No surprises on the list but imagine if America worked on decreasing all of these…

The highlight of the day was a seminar on food and fertility by Dr Victoria Maizes who works with Dr Weil at the University of Arizona and I’ve seen present on diet and cancer before.  She is a fantastic speaker and offers suggestions versus mandates.  It startling when you look at the fertility data. Many women postpone having children to focus on work while fertility starts to decline in our 30s. As far as diet, it matters more vis-à-vis fertility as we get older, if that makes sense. So what’s been associated with decreased fertility?

1. Cereal- many foods were tested and cold cereal, likely because of glycemic index, decreased fertility more than most others
2. Nonfat milk- you know, if you read regularly, I’m not a skim fat but while nonfat milk decreases fertility whole dairy improves it.
3. Trans fats – a 2% increase in trans fats was associated with a 73% increase in infertility, think packaged products and read labels for hydrogenation. Trans fats were on Lustig’s list above and they really are about as bad for us as we thought, it not worse
4. Soda but not necessarily all caffeine

What foods improve fertility?

1. Whole Dairy
2. Fish/omega 3's- many women cut out fish due to mercury phobia and this is a mistake. Omega 3’s decrease miscarriage risk, postpartum depression and certain pediatric cancers.
3. Prenatal vitamins- I am not such a multivitamin all in one fan but feel strongly, after this presentation, that both men and women trying to conceive should be taking one (though not the same one).

What happens in utero and what women do before they conceive really, as Dr Maizes said “wires you for the rest of your life”. So I can focus on my mother and how screwed I am or I can try to pass this information on.  And finally, infertility isn’t always discussed and has to be one of the hardest things to go through. I have a sister to struggled with IVF and I tried for a long time with my older son. Dr Maizes reminded us of the compassion needed. I also think “tools” are helpful so please, if appropriate, pass this information along. And congratulations to all the Boston runners, well done.

 I have to get over to the Westin for today’s sessions. I’ll tweet @Foodtrainers about  them if you want to hear more.

Are you eating much of the apocalyptic foods? Or are you limiting fish due to mercury concerns? What do you think makes a good speaker or presentation?
