Top Ten Trends in the Global Food Industry

by Janet on July 22, 2012

Innova Market Insights identified ten top trends in the global food industry at IFT’s annual meeting and food expo, which was summarized in Food Product Design. Here’s a look at the trends, especially from a product R&D point of view:

1. Pure is the new natural.

dannon pureThe term “natural” has come under attack, particularly because consumers and the industry have different definitions of what “natural” really means. As a result, the term “natural” on package labels may be falling out of favor.Now it appears that “purity” is more popular.  Claims of  “pure” on the label have doubled from 2008 to 2009, a third more were added in 2010 and “considerably more” in 2011. Innova suggests that use of stevia helps contribute to a food’s “pure” image.

2. Green is a given.

Showing how you care of the environment has become mandatory, but the way “green” is communicated varies. Corporate social responsibility is playing an increasingly important role. Innova cites more “waste” or byproduct materials developed into nutritious and functional ingredients. Another tier of this trend is the use of “ethical” claims, such as eco-friendly, biodegradable, compostable, recyclable, carbon footprint, fair trade, animal friendly, free-range, and general sustainable claims.

3. Location, location, location

Increasingly, people want to know where their food comes from.   Manufacturers are touting authenticity, attempting to build intrigue with a sense of place and showing transparency regarding ingredient origin. The trend includes an increased interest in traditional and regional foods from around the world, and the dialing down of ethnic cuisine to regional specifics, such as Copper River salmon and California almonds.

4. Premium stands out

Even with today’s tough global economy, premium foods remain attractive—they’re affordable indulgences. Innova says consumers often shop at the extremes of the market, seeking-out big discounts at one end and ultra-premium products at the other.

5. Seniors get some attention

With our aging global population, expect to see an increase in products that help seniors age gracefully. Innova says some keywords and concepts used in products for this market include easy to open, easy to digest, reduced acid, for strong bones, specifically formulated, nutritionally balanced, improved health, easy to read labels, and lightweight packaging.  The “easy to swallow” attribute is popular because  22% of 50+ year olds suffer from dysphagia. Foods need to be “easy to eat,” with the right consistency. High protein content (fortified with whey protein) is also important to help prevent sarcopenia, or age-related loss of muscle mass. Flexibility of product use is also important, such as a food that can be eaten either as a snack or dessert.

6. Forty is the new twenty5168930691_013879a94b_b

Boomers are helping define the art of aging gracefully, yet research indicates that consumers need to get into that nutritional mindset before senior status kicks in to truly age well. This expands the scope of products that have some type of “anti-aging” positioning. Maintaining vision is a key priority, and products with eye-health benefits are on the rise, up from 71 in 2008 to 138 in 2011 say Innova. Other key nutrients for this group, per Innova, include resveratrol, omega-3s, CoQ10, gingko biloba, L-carnitine and those found in green tea.

7. Grounded in science

When the increase in products making some type of nutrition claim, expect to see  greater use of “scientifically proven” claims on packaging, such as the connection between vitamin C and immune health. Yet the claims that are not officially approved by FDA will require judicious wording to avoid regulatory scrutiny. Therefore, label and marketing support for functional ingredients that are not approved for specific claims will  rely on explanations of their key nutritional properties, such as ingredients that are “rich in antioxidants,” says Innova (although the antioxidant claim has been heavily scrutinized recently).

8. Regulators force a rethink

Any time there are  changes in food policy or regulatory activities, there are shifts in the food industry. For instance, when labeling of trans fats in the Nutrition Facts became mandatory, the industry was a flurry of reformulation and new products were designed to avoid trans fats. And this wasn’t just a U.S. issue, it affected R&D around the world. The industry saw 566 new global product launches with “No trans fats” on the label in 2005; by 2011, that number was 5,021.  So what’s next?  Some municipalities have proposed “fat taxes” that would include foods high in saturated fat, as well as products like soft drinks.  Innova says manufacturers are trying to stay ahead of the curve, keeping product nutritional profiles front and center when beginning product R&D, or when reformulating. They cite examples like oven-roasted chips, products touting use of less salt, and highlighting use of specific oils, like sunflower oil, often with specific claims outlining the fatty-acid makeup (such as unsaturated fats vs. saturated).

9. Unmeasureable niches

Innova suggests that smaller manufacturers have an improved ability to compete in today’s market as it strives to meet more specific dietary needs of consumers, opening niches that bigger players might be hesitant to approach. Some consumer segments have also developed pronounced tastes and desires for specific, niche products. Social media can play a role here in reaching targeted groups of consumers.

10. Boom for protein

2760450189_194a6ff305_bProtein continues to be top of mind for consumers, and Innova says specific types of protein are seeing strong demand, sometimes tied to the relative sustainability of the source. For instance, global product launches for foods with potato protein have grown from 8 in 2008 to 41 in 2011. Many of the protein-enhanced products are touted for weight management, while others promote the benefits of plant protein.

What’s Hot in Produce for 2012

by Janet on July 18, 2012

I’ve already written about lots of food trends for 2012, here’s a recap of some of those posts in case you’ve missed:

2012 Hot Restaurant Trends 
2012 Food Trends:  What’s Hot, What’s Not 
Chefs Predict Top Menu Trends in 2012 
Top 10 Restaurant Trends for 2012

Now let’s look at produce — the trends in fruits and vegetables that were identified by the National Restaurant Association’s survey of American Culinary Federation members.  Here are the hot 27 produce trends identified by the 1,800 chefs:

1. Locally grown produce
2. Organic produce

I’m not surprised that local produce is ahead of organic; several consumer studies reveal that locally grown is a more important attribute than buying organic.  In fact, locally sourced meats and seafood, locally grown produce and hyper-local sourcing (restaurant gardens), were among the top overall trends in the What’s Hot in 2012 survey.

3. Superfruits (acai, goji berry, mangosteen)
4. Exotic fruits (rambutan, dragon fruit, paw paw, guava)

I’m wondering if the superfruits trend will be over in 2013.  Let’s think of all fruits as super, and begin to enjoy a variety of  fruits more often.  I do like the idea of more exotic fruits, as long as you’re getting the real deal, and not just a juice drink or a tiny amount of extract inside of a “nutrition bar,”  smoothie or other product.  

5. Heirloom apples
6. Heirloom beans

Heirloom is a broad trend, that transcends fruits and vegetables, as well as animal breeds.  Heirloom tomatoes (trend 11) may have been the first to break through, but now the heirloom description is more widely used (yet, is there some “heirloom washing” going on?).  Nonetheless, I’m especially enjoying heirloom beans.

7. Specialty potatoes (purple, fingerling, Baby Dutch Yellow)
8. Micro-vegetables, micro-greens
9. Hybrid fruits/vegetables (plumcot, grapple, broccoflower)

Grapple is one example of the hybrid trend.  It’s a cross between an apple and a grape.  Have you tried it?  I actually haven’t yet, but curious.

10. Fresh herbs
11. Heirloom tomatoes
12. Dark/bitter greens (collards, kale, beet tops)

There’s been lots of love for bitter greens, especially kale, which has become the big breakout star on Pinterest.  It’s great in salads, but also an ingredient in pasta, soups, stews, and casseroles. 

13. Root vegetables (parsnip, turnip, rutabaga)
14. Fresh beans, peas (fava, sweet, snow)
15. Asian mushrooms (shiitake, straw, enokitake, cloud ear fungus)
16. Hot peppers (habanero, chipotle, jalapeno)
17. Pomegranates
18. Fennel

19. Passion fruit
20. Edamame/soy beans
21. Avocados
22. Beets

Beets are no longer just featured in salads (especially the classic combination with goat cheese).  Now raw beets seem to be all the rage, including raw beet ravioli.

23. Tomatillos
24. Radish/daikon

27. Cauliflower

What vegetable or fruit would you add to the list?

green coffee beans on vine There’s been a lot of buzz about green coffee bean extract. But it’s disheartening for me to see yet another diet pill get so much press — including the recent love fest on the Dr. Oz show. Green Coffee Beans have emerged as the new Raspberry Ketones — similarly described by Dr. Oz as a “miracle pill that can burn fat”  and a “magic cure for weight loss.”   Once again, an endorsement by Dr. Oz seems to set off a fire-storm with companies scurrying to bottle this miracle and set up  websites to sell it– often using photos and quotes from Dr. Oz  himself.  There’s even a OzGreenCoffee page on Facebook.

green coffee beans

So how did this new frenzy get started?  Like many of today’s popular dietary supplements, there’s a small study (often paid for by the pill manufacturer) that gets the ball rolling.  That’s exactly what happened with Green Coffee Beans.  All of the recent claims are based on a single study of 16 people conducted in India.  The lead author is Joe Vinson, a chemist at the University of Scranton, Pennsylvania, who has conducted other studies examining polyphenols and other natural compounds in foods.  Funded by the supplement manufacturer Applied Food Sciences in Texas, the study was published in the online journal Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy; you can read the full paper here.

Science-Based Medicine does an excellent job of analyzing the study in the post:  Dr. Oz and Green Coffee Beans – More Weight Loss Pseudoscience.  Author Scott Gavura concludes that the study has some serious methodological problems including the small sample size, lack of proper blinding, doses, unreliable diet recalls, and repeated measurements. The study was also not registered at clinicaltrials.gov, according to Scott Gavura, which he believes is a red flag.

Many medical journals will now refuse to publish a trial if it was not initially entered into a public registry. Not only does a registry ensure that negative results don’t disappear, it gives valuable information about the study, including its design, entry criteria, and who gave formal ethics approval for the study….I find it hard to believe that any investigator would undertake a clinical trial of an unproven supplement without obtaining prior ethics approval — but that seems to be the case.

Like many of today’s popular dietary supplements, including weight loss pills, there’s typically a small nugget of truth buried beneath all the hype.  Often preliminary studies do indicate a “suggestion” or the possibility a natural compound could have potentially beneficial effects in the body.  That appears to be the case with green coffee beans, which are rich in a type of polyphenol called chlorogenic acid (the purported active ingredient in the supplements). Historically, there’s been some research to suggest that regular coffee intake is linked to a healthier body weight, possibly due to the caffeine or the polyphenol content in the drink. That lead to this 2011 review paper on green coffee extract or GCE by Igho Onakpoya and colleagues (funded by GlaxoSmithKline) that explored the efficacy of GCE as a weight loss supplement.  The authors identified five clinical trials, although only three studies (published in 2006, 2007 and 2009) met the quality criteria for the review. However, all of the studies, the authors indicated, were associated with a high risk of bias. They concluded:

The evidence from RCTs (randomized clinical trials) seems to indicate that the intake of GCE can promote weight loss.  However, several caveats exist.  The size of the effect is small, and the clinical relevance of this effect is uncertain.  More rigorous trials with longer duration are needed to assess the efficacy and safety of GCE as a weight loss supplement.

Other experts have expressed their concern about popping green coffee bean extract, including these two physicians who were interviewed about the Vinson study by the LA Times:

Dr. Gerald Weissmann, a physician and biochemist at New York University:

This is certainly a provocative study, but nutrition experts would want assurances that green coffee beans do not cause malabsorption within the human gut — a condition that would lead to weight loss as well as malnutrition, heart arrhythmias and other problems because vitamins and minerals are not passing through the intestines.

Dr. Arthur Grollman, a pharmacologist at the State University of New York at Stony Brook

Coffee beans contain about 250 different chemicals — some with positive and others with negative effects on human health. Though Vinson identified polyphenols and chlorogenic acid as the agents that appear to promote weight loss, that claim needs further study.  In the meantime, consuming an extract that contains both good and bad chemicals in dense concentration seems an unwise thing to do.

Chlorogenic acid is found naturally in raw or green coffee beans, yet the supplement marketers claim that roasting destroys this beneficial compound. That’s why you need to buy it in pill form. Yet, Scott Gavura of Science-Based Medicine says that’s not true. He cites this study that shows chlorogenic acid is also present in roasted coffee and black tea

So is it a bad thing to buy green coffee bean extract? What’s the harm? I wouldn’t recommend for several reasons: First, all the promoters make a big deal about how participants in the study lost 17 pounds without making any changes in their eating or activity. All they did was take the pill. For sustainable weight management, it does come down to your daily habits, not relying on a pill to help you meet your goal. You can’t just take a supplement and then ignore what you eat and don’t make an effort to be more active. And if you don’t get the miraculous results — like the woman on Dr. Oz’s show who lost a 1 pound a day for 5 days — then you feel like a failure and you’re then seeking the next big miracle pill. It’s a never-ending cycle. And it’s money in your pocket that you could be spending on real food.

Yes, maybe there’s a biological effect due to chlorogenic acid. Lots of natural compounds in food go to work in different ways once we eat them. But the effect on our weight is likely very small. There are so many other things that we could be doing that would make such a bigger impact — such as eating more fruits and vegetables each day, keeping sight of portions, increasing our activity, and even enjoying coffee (in a cup instead of a pill).

Overcoming Your Fear of Fat

by Janet on July 5, 2012

olive oil pouring - Selfish VeganLong demonized, dietary fats have made a break from the past, and I couldn’t be happier about it. Even so, the concept of good fats is an oxymoron for some folks.  It’s just stuck in their heads that all fat is bad.  But we’re a long way away from the old food pyramid that dumped all fat and oils into the tip with a warning to “use sparingly.”  Now liquid oils and other good fats like nuts have earned a coveted spot on USDA’s MyPlate.  For most adults, we should aim for 5-7 teaspoons of oils each day (which includes nuts, olives and avocados).

The topic of good fats was the focus of my latest blog for WebMD’s Real Life Nutrition.  In the post, I talked about a new Purdue study that should make you think twice about buying a fat-free salad dressing.  Researchers at Purdue found that a fat-free or low-fat salad dressing reduced the absorption of fat-soluble carotenoids – beneficial compounds in the salad such as lutein, lycopene, beta-carotene and zeaxanthin. So by buying some type of bottled fat-free dressing instead of mixing up your own vinaigrette with a luscious-tasting extra-virgin olive oil, you’re not only missing out on the benefits of the oil, you’re getting less out of the salad you just tossed.  Plus, just think how much better it’s all going to taste with your own dressing.

The study’s lead author Mario Ferruzzi advised:  

If you want to utilize more from your fruits and vegetables, you have to pair them correctly with fat-based dressings.  If you have a salad with a fat-free dressing, there is a reduction in calories, but you lose some of the benefits of the vegetables.

This is just another reason why it’s best not to assume that fat-free or low-fat is always better.  Sometimes you’re not even saving calories, as this comparison chart illustrates, and the “low-fat” health halo could coax you into eating twice as much, as three recent studies from Cornell University have shown. You also need to look at the ingredients that were used in a product to replace the fat (maybe extra sugar or refined carbs, perhaps more additives).  Even messages about eating a low-fat diet can backfire, as this overview from Harvard  asserts:

One problem with a generic lower fat diet is that it prompts people to stop eating fats that are good for the heart along with those that are bad for it.

So that’s the big  issue.  We need to get over our fear of fat so we won’t miss out on the multiple benefits of “good fats.”  And we need to get past the idea that low-fat is always better.  Here are some suggestions from Cornell University’s Food and Brand Lab on how to avoid the low-fat trap:

  • Pay attention to the calorie count of foods, particularly low–fat foods. When researchers went to a grocery store and looked at the fat and calorie content of various packaged foods, they found that although the low–fat versions of these foods have 59% less fat than the regular versions, the drop in calorie content is only 15%, which is not large enough to justify our increased consumption.
  • Understand what claims like “low–fat” and  ”reduced fat”  really mean, and be sure you’re looking at serving sizes on the label.
  • Consider buying regular or full–fat versions of snack foods instead of the low–fat ones if you think you’ll still be tempted to overeat. This is especially important for overweight people who showed a strong tendency to overeat low–fat foods, regardless of serving size labels. Also, some research shows that the ingredients companies use to replace the fat can actually make you hungrier, causing you to overeat.
