Harvard Health Ad Watch: Are nutritional drinks actually good for you?


I first heard of dietary drinks within the Nineteen Eighties, early in my medical coaching. They have been really useful for individuals struggling to take care of a wholesome weight, typically on account of lack of urge for food, most cancers, or swallowing issues.

Since then, dietary complement drinks like Enhance and Guarantee have gone mainstream. Their widespread, primetime promoting geared toward a much wider viewers has confirmed extremely efficient. The marketplace for dietary drinks is now value many billions of {dollars}. In 2019, Guarantee gross sales alone totaled practically $400 million.

If you watch adverts for dietary drinks, do you surprise if you happen to ought to begin consuming them? Will it enhance your well being or fend off future well being issues, because the adverts recommend? Are there any downsides? Learn on.

What the adverts say

Proper now, two adverts in heavy rotation are for Enhance and Guarantee.

One 30-second advert for Enhance reveals a well-appearing older girl holding a digicam (an actual, two-handed, skilled photographer’s digicam, not a cellphone). As she takes images of a younger, hipster musical group, she tells the viewer, “I don’t maintain observe of regrets. And I don’t add up the years. However what I do rely on is staying glad and wholesome. So I add protein, nutritional vitamins, and minerals to my weight loss program — with Enhance.”

As she fortunately sips her chocolate drink, a voiceover tells you extra. “Enhance high-protein dietary drink has 20 grams of protein, together with 26 important nutritional vitamins and minerals your physique wants.” A graphic of a human physique with an inventory of eight of those nutritional vitamins and minerals is displayed: calcium, vitamin D, magnesium, vitamin C, B nutritional vitamins, iron, zinc, and potassium.

Then comes the large end and trademarked tagline: “All with assured nice style. And now attempt peaches & cream pure taste. With 27 nutritional vitamins and minerals and 10 grams of protein. Enhance — be up for all times.”

Guarantee’s 15-second advert takes a really completely different tack. Right here we’ve animated meals characters — an egg, a pear, a carrot, and a few broccoli — hanging out collectively within the fridge. So lovely! An egg appears off digicam and exclaims, “Wow!” A bottle of Guarantee Unique explains what the egg is admiring: “That’s Guarantee Max Protein with excessive protein and 1 gram of sugar.” Shift to a towering bottle of Guarantee Max, full with bulging biceps, sounding like a drill sergeant shouting orders on the banana: “It’s a sit-up, banana, bend on the waist.”

“I’m attempting!” says the banana, because it rocks backwards and forwards on its again. “Stick with it, you’ll get there,” Guarantee Max barks. Two bottles of Guarantee high-five one another. In the meantime, the banana falls backwards, failing to finish even a single sit-up.

A voiceover breaks in: “30 grams of protein, and 1 gram of sugar. Guarantee Max Protein.”

What the adverts recommend

The suggestion is evident: to be wholesome, you’ll want to be consuming these dietary supplements. A nutritious diet gained’t suffice.

Product names ship their very own message. You’ll be able to “increase” your well being and “guarantee” you’re getting all of the vitamin you want by consuming these drinks. The Enhance business appears to focus on older individuals, implying that downing bottles of Enhance often might help you retain up with the younger people and preserve an energetic, wholesome, and dealing life nicely into superior age. The Guarantee business, in the meantime, means that whereas train could be a chore, a minimum of your vitamin will likely be lined by this high-protein complement drink.

What the adverts don’t say

The knowledge supplied in these adverts and on their web sites is mostly correct. Individuals who don’t get sufficient energy, protein, or sure minerals or nutritional vitamins might make up for what’s lacking by consuming these drinks. As well as, there are completely different variations of those merchandise for individuals with diabetes or different well being issues.

However these adverts are lacking necessary info. For instance:

  • Who advantages? Some persons are much more probably than others to learn from Guarantee, Enhance, or related merchandise. The overwhelming majority of individuals can get all of the vitamin they want from their weight loss program. There’s completely no proof that these dietary supplements enhance well being or stop illness in individuals who haven’t any particular dietary issues, as my colleague Suzanne Salamon, MD, notes. Nonetheless, if you happen to’re shedding weight involuntarily and don’t carry extra weight within the first place, or if you happen to can’t soak up sufficient vitamin, you may profit from dietary dietary supplements.
  • Ought to dietary supplements exchange meals or be added to them? The adverts don’t say. In reality, the recommendation would fluctuate relying on the individual’s total heath and weight loss program.
  • Vital energy. Common Enhance has 240 energy; Guarantee Max Protein has 150 energy; authentic Guarantee has 220 energy.
  • Sugar and synthetic sweetener. Common Enhance has 20 grams of added sugar. Whereas Guarantee Max Protein has just one gram of sugar (together with a man-made sweetener, sucralose), authentic Guarantee has 14 grams of added sugar.
  • Value provides up. I discovered these merchandise on the market on-line for round $2 per bottle. Relying on what number of you drink every day, the price could be important, particularly over the long run. You will get related quantities of protein, nutritional vitamins, and minerals at far decrease value from high-protein meals (equivalent to milk or yogurt) and a multivitamin. And, chances are you’ll not want that multivitamin.
  • Excessive protein isn’t for everybody. Some individuals ought to keep away from high-protein diets, and subsequently ought to not devour high-protein dietary dietary supplements. Individuals with important kidney illness are a great instance.

The underside line

The worth of Enhance, Guarantee, or their rivals to the overall inhabitants is questionable. One of the simplest ways to determine if you happen to ought to devour these merchandise is to debate your well being, medical issues, and weight loss program together with your physician. She or he could suggest that you simply seek the advice of with a nutritionist.

I’ll go away you with some questions I discover perplexing. Why would a dietary complement yell at a banana to do a sit-up? How can the banana bend on the waist when it has no waist? And why is the banana the one meals being requested to work out? In the event you ask me, the pear and egg look a bit large across the center. Maybe the failure of the banana to do a sit-up is a metaphor for our personal lack of ability to do the work of train ourselves — and so we want assist from a dietary drink. I’m most likely overthinking this; it’s probably simply an attention grabbing approach of selling a product. However if you happen to perceive this business higher than I do, please let me know.

Within the meantime, my recommendation is to decide on a nutritious diet (just like the Mediterranean weight loss program), get common train, and don’t rely on dietary drinks — or the bodily health of your fruit — to maintain you wholesome.
