In this fourth and final post of the Sweet Tooth Truths series, Iâm going to give you the scoop on natural sweeteners. From agave to yacon syrup, we’re going to take a look at some of the most common natural sweeteners and what we know about how they impact our bodies.
One of the common questions that stood out during the Sweet Confessions talk was, âHow much sugar should/can we eat?â
The reality is that even the experts can’t seem to agree on a magic number. The World Health Organization (WHO) suggests no more than about 12 teaspoons per day, while the American Heart Association (AHA) says 6 teaspoons for women and 9 teaspoons for men.
Regardless of whom you ask, the main thing to keep in mind is that we don’t want to eat a lot of sweeteners, even if they are from natural sources. Theyâre meant to be used in moderation but arenât an essential part of our diet.
They just happen to taste really good and make food more enjoyable đ
Dr. D’Adamo rounded out his presentation making this point about sweeteners in general:
So keep that in mind as you read through this list of sweeteners and whatâs recommended for each.
If you want to get even more detailed information about each of these sweeteners and others not covered in this post, check out this website. Itâs an excellent resource!
Agave
The Basics: Indigenous to Mexico & South America, agave is the slow boil of sap of the agave plant. There are many species, but itâs usually derived from “Blue Agave.” Tequila is fermented agave. Agave is marketed as a âlow glycemicâ sweetener because its glycemic index (GI, which measures the impact of a carbohydrate on our blood sugar) is 15, but itâs primarily made up of fructose, which can be tough on our liver and favors fat storage.
Where to Find It: Syrups, cereals, nutrition bars
The Controversy: Most modern agave is highly refined, full of pesticides, genetically-modified and has minimal antioxidant content. “Raw” & organic agave is less refined and likely more nutritious but we want to limit consumption even if it is raw and organic for a number of reasons:
- Very high in fructose (up to 90% fructose compared to HIGH fructose corn syrup which is 55% fructose!), which is primarily metabolized in the liver
- Increases triglycerides (fat in our blood) and VLDL (dangerous cholesterol)
- Increases appetite
Stevia
The Basics: Obtained from South American shrub yerba dulce, stevia is an herb that has been used for thousands of years for sweetening. Itâs nearly calorie-free and is 100 times sweeter than sugar but can have a slightly bitter aftertaste.
Where to Find It: Truvia, PureVia, SweetLeaf, stevia extracts, flavored water, diet soda, yogurts
The Controversy: In the 1990s, it was rejected by the FDA, Canada and Europe for use as a sweetener because of concerns over reproductive problems in rats and hamsters, but it has been used in South America and Japan for many years. In 2008, the FDA classified stevia as GRAS (“Generally Regarded as Safe”), and the food industry started including it in beverages and marketed it heavily as a natural alternative to artificial sweeteners.
The other compound in stevia has not been linked to tumors or reproductive problems in rats over several generations. However, those studies were funded by the food industry and can be found here and here.
There have been few independently-funded human studies on stevia, but those that have been done have found it does not increase blood sugar more than placebo and lowers blood pressure.
Recommendation
Choose your stevia wisely. As always, read labels, choose organic if possible, avoid additional ingredients (for instance, Truvia contains erythritol and natural flavors and Stevia in the Raw contains dextrose and maltodextrin), and use stevia in moderation until more is known.
Honey
The Basics: Honey is made when bees collect flower nectar, combine it with salivary enzymes, and store it in their hives. Honey has been used as food & medicine in Ayurveda, traditional Chinese Medicine, and by the Greeks for over 5,000 years.
There are many varieties of honey, including clover, buckwheat, manuka, thyme, lavender, etc. The color varies by the nectar of different plant sources. There are also several forms of honey, including liquid, creamed and honeycomb.
Where to Find It: Cereal, granola, yogurt, nut butters, nutrition bars
What Science Says
Honey has multiple health benefits, including the following:
- Strong antioxidant & antimicrobial effects
- Effective in wound healing
- Reduce coughs in children better than dextromethorphan
- Contains nutrients that protect against cancer
- Contains probiotic bacteria & prebiotics that promote digestive (and therefore overall) health
- Provides relief from seasonal allergies (many prefer local honey for these purposes)
Reasons for Concern
- Avoid honey in infants under one year because it may cause botulism
- Often contaminated by environmental factors, including pesticides, heavy metals, genetically modified plants, etc. For that reason, itâs important to know where your honey is sourced
Recommendations
- Use in moderation because itâs high in sugar (GI = 50, but relatively high in fructose)
- Best choice: organic (less exposure to pesticides), local (likely to benefit seasonal allergies), raw honey (more enzymes, nutrients)
- Darker honey has more nutrients (include buckwheat, honeydew, manuka)
- Traditional or creamed is not likely to have any health difference but is traditionally easier for teas, and creamed honey is easier for spreading
Other Natural Sweeteners
Blackstrap Molasses
âUnsulphuredâ blackstrap molasses has the most antioxidants and potassium of any natural sweetener and come from cane sugar manufacturing. Itâs also very high in iron, so itâs sometimes used as a supplement for people who have anemiaâPhillips (2009) J Am Diet Assoc. 109(1):64-71. Be aware that, despite its health benefits, it has a GI of 55 and is 30% fructose, so itâs not suitable for diabetics and should be used in moderation, as with all other sweeteners.
Maple Syrup
This natural sweetener comes from the sap of maple trees. Rich in antioxidants and high polyphenol (protective nutrients in plants) content. Dark maple syrup is high in magnesium, potassium, etc. (Theriault (2006) Food Chem 98:490â501). Its GI is 54, and it is about 35% fructose, so use it in moderation.
Make sure you are buying PURE maple syrup (not Log Cabin or Aunt Jemima, which are usually full of high fructose corn syrup). We prefer Grade B maple syrup, as it’s darker and richer than Grade A.
Coconut Palm Sugar
With a look similar to brown sugar, coconut palm sugar comes from the flower blossoms growing on palm trees, which produce a liquid nectar. It has a low GI (35) and low fructose content (<30%), so its use is encouraging but does not yet have much supporting science. Also, even though it contains more vitamins and minerals than white sugar, it doesnât contain any fiber and is essentially pure sugar, so enjoy it in moderation.
I use coconut sugar in my Snickerdoodle bites and this fruit crumble.
Luo Han Guo (Monk Fruit)
The plant is native to southwestern China, where it has been known for hundreds of years and used for medicinal purposes. Itâs used as a natural, zero-calorie sweetener with a glycemic index of 0, so itâs suitable for diabetics. Itâs about 300 times sweeter than sugar.
Here is a site with more info about Monk Fruit.
Yacon SyrupÂ
A natural sweetener made from the root of the Yacon plant in South America. It contains fructooligosaccharides, which promote the creation of beneficial bacteria in our digestive system, and helps to âbulk upâ our stool to remove waste from the body.
Several studies have shown Yacon syrup to be effective as a weight loss tool, but itâs very expensive (about 30 times as much as sugar!), so itâs not widely used.
Dates
Usually dried or in the form of date sugar or date paste. Theyâre a better option than other sweeteners because they are a whole food and are high in tannin antioxidants. Like most dried fruit, they are high in fructose, so moderate your consumption. I prefer Medjool dates to Deglet dates because they have more of a caramel texture and work better in recipes.
Berries
The best âsweetenerâ for many health benefits, including fiber, antioxidants, vitamins, minerals, and phytochemicals. Enjoy a variety because different berries have different nutrients.
So, there you have it! Those are some of the top natural sweeteners to include in your diet. It’s ideal to eat them in moderation, but food is meant to be enjoyed, and they make food more enjoyable for sure đ Didn’t see a sweetener you’re curious about on the list?
