What counts as processed meat (and why eating a hot dog won’t kill you)

Debbie asks: “What’s the definition of processed meat? Everyone seems to agree that we should avoid it. But I’m never sure what counts. Hot dogs and bologna seem obvious. Is sausage considered processed? What about sliced lunch meat at the deli?”

Researchers have found that people who eat the most processed and/or cured meats have higher risk of things like heart disease and cancer. Naturally, people who pay attention to these sort of things want to know which meats are on the “bad” list.

Unfortunately, there is no single definition–and the validity of the association between processed meat and disease risk has a lot to do with what’s included. In some studies and surveys, processed meat is any meat that has been cured, smoked, dried, or had anything added to it, including salt, seasonings, or preservatives. Other studies have a separate category for cured meats.

So, what exactly are we supposed to avoid? Pepperoni seems pretty obvious. But what about smoked salmon or uncured bacon? Is a package of sliced turkey breast off limits?  Continue reading “What counts as processed meat (and why eating a hot dog won’t kill you)” >

Vitamin C and Death: More Face-Palm Science News

I sometimes play a game on the Nutrition Diva Facebook page called “Spot the fallacy.” I post a link to a nutrition-related  story and followers chime in, pointing out all the ways in which the science had been distorted or misreported.  It’s always lots of fun.

Here are a couple of recent rounds of Spot the Fallacy:

Usually, the problem is not with the research but with the way it’s being reported. But here’s a new category of face-palm science. Researchers take an interesting finding and then “drill down” to come up with a far less meaningful conclusion. Wanna play? Continue reading “Vitamin C and Death: More Face-Palm Science News” >

Why cake may be better than bread

chicken-veggiesHere’s a small study that may change the way we think about carbs. Researchers found that the order in which we consume foods may have a substantial impact on our blood sugar response to those foods.

In the study, subjects were given the same meal–consisting of chicken, vegetables, salad, bread, and orange juice–on two different occasions. The first time, they ate the high carbohydrate foods (the bread and orange juice) first, followed by the chicken and veggies.  The second time, they reversed the order and ate the chicken and veggies first, followed by bread and orange juice.

In a traditional nutritional analysis, these two meals would be considered identical. But it appears that even small differences in timing make a big difference. Continue reading “Why cake may be better than bread” >

What does moderation mean, exactly?

Dear Nutrition Diva,

moderationCould you please explain exactly what the term moderation means? I hear all the time that we should eat certain foods ‘in moderation’ but no one ever tells us what moderation is. Is it a small amount regularly? Is it a larger amount less often? I’m really interested to hear your take on this because it seems to be a matter of opinion. One person’s moderation could be another person’s excess.

Thanks, Tosin

I absolutely love this question…because it shows that I’ve been falling short.

Like many nutrition experts, I use the word “moderation” freely but I don’t always define it. I just assume that you know what I mean. Or maybe I’m just being lazy. As Tosin so accurately points out, what may be moderate for you may be excessive for me.  Continue reading “What does moderation mean, exactly?” >

Is canned fish the ideal source of calcium?

sardine_can_icon_by_yamshing-d578pmy[1]In a Nutrition Diva podcast on the best sources of calcium, I wrote:

“Fish such as sardines and canned salmon are great sources of calcium because they contain tiny bones that are so soft you’d never notice them but are rich in calcium. As a bonus, these fish are also among the few natural food sources of vitamin D [which helps your body absorb and use that calcium.]”

A 3 oz can of salmon or sardines can provide up to 25% of your daily calcium requirement and 100% of your vitamin D–not to mention a healthy dose of omega-3 fatty acids.

But not always. Continue reading “Is canned fish the ideal source of calcium?” >

Recipe: Pesto Grilled Asparagus

imageAs I pinched back my basil plants this morning, I suddenly realized that I still have a couple of packets of pesto in the freezer from last year’s harvest. Obviously, I can’t start making this year’s pesto until last year’s is consumed!

Yet, in the midst of a several-day stretch of hot, humid weather, I just couldn’t see putting a pot of pasta on to boil. Instead, I thawed out some pesto and tossed it with some asparagus I picked up from the farmer’s market this week and threw it on the grill for 15 minutes. The results were too good not to share.

I use this Epicurious recipe for basic pesto as a template, but often substitute other greens (such as arugula) or nuts (such as walnuts).

Why you should look for peanut butter made with unblanched peanuts

peanut butterDan wonders how you can tell whether peanut butter was made with the peanut skins–that papery reddish stuff that surrounds each nut. As Dan points out, these skins are quite rich in phenolic compounds (fancy antioxidants) and peanut butter made with the skins is a lot more nutritious.

Eggs are back on the menu for diabetics

Eggs for breakfast helps you eat lessThe government finally relaxed its stance on cholesterol in this year’s Dietary Guidelines for Americans, but, as you know, I have been defending eggs as delicious, nutritious, and unfairly maligned for years.

I’ve reassured people that it’s fine to eat eggs everyday–assuming you are otherwise healthy. But with nutrition, one size never fits all.  Thus my “assuming you are otherwise healthy” caveat. Continue reading “Eggs are back on the menu for diabetics” >
