Perhaps in response to my rant about marketers and bloggers, I received an email yesterday inviting me to join #WelchsGrape Twitter Party! The purpose of this “party” is to spread the idea “Moms can help their families live a heart healthy lifestyle with Welch’s 100% Grape juice made with Concord Grapes.”
One easy and delicious way to add more purple to your family’s diet is to drink 4-oz. of grape juice, which offers a full serving (1/2 cup) of fruit and no added sugar.
This is pretty disingenuous. Grape juice is loaded with natural sugar. I can’t even imagine how you’d drink it if they added sugar. A 64 oz bottle of Welch’s Grape Juice contains 8 8 fl oz. servings. Each 8 fl oz serving (1 cup) contains 40 grams of sugar. One can of Pepsi (335 ml or ~1 1/2 US cups) contains 40 grams of sugar.

Think about that: 1 cup of grape juice is basically 1 can of Pepsi. Official US Guidelines advise a maximum of 40 grams refined sugar for every 2000 calories consumed per day. So give your kid even 1/2 cup of grape juice and you’ve given them more than half the sugar maximum an adult should consume as day. This isn’t right because the guideline is for added sugar, like when you see “sugar” in the ingredients list for tomato sauce. Grape juice has no added sugar, but it’s concentrated to make it sweeter. There is no guideline for how much naturally-occurring sugar you should ingest.
It’s hart to believe any possible heart benefits associated with grape juice outweigh the risks of ingesting so much sugar (with none of the fiber or slower digestive process to access it that you get from eating whole fruit rather than mainlining juice!) If you haven’t yet read Is Sugar Toxic?, get thee to the New York Times post haste:
The fructose component of sugar and H.F.C.S. is metabolized primarily by the liver, while the glucose from sugar and starches is metabolized by every cell in the body. Consuming sugar (fructose and glucose) means more work for the liver than if you consumed the same number of calories of starch (glucose). And if you take that sugar in liquid form — soda or fruit juices — the fructose and glucose will hit the liver more quickly than if you consume them, say, in an apple (or several apples, to get what researchers would call the equivalent dose of sugar). The speed with which the liver has to do its work will also affect how it metabolizes the fructose and glucose.
In animals, or at least in laboratory rats and mice, it’s clear that if the fructose hits the liver in sufficient quantity and with sufficient speed, the liver will convert much of it to fat. This apparently induces a condition known as insulin resistance, which is now considered the fundamental problem in obesity, and the underlying defect in heart disease and in the type of diabetes, type 2, that is common to obese and overweight individuals. It might also be the underlying defect in many cancers.
The whole article is worth a read. Then you can decide for yourself if filling your kids with juice is “heart-healthy” and if you want to join the Twitter party to spread the word. Or you can crash the party with me (if naps coordinate with party time) and point people to some sane information about kids and sugar.
And I don’t even want to get started on the idea that drinking juice counts as a serving of fruit! That’s about as specious as ketchup being a vegetable.
