Guarana: The Low Down on a Hyped-Up Herb

guarDoes the herb guarana pack the same caffeine punch as coffee? Guarana, pronounced gwa-rah-na, is an herb from South America and is very popular as a stimulant in energy drinks with names such as Pit bull, Pimp juice, Rip It, Venom and Cocaine Energy Drink whose website says it tastes like a fireball, a carbonated atomic fireball!’.

When I say caffeine, what’s the first thing you think about? Coffee? Maybe tea or chocolate? Like tea, coffee, and chocolate, guarana contains compounds in the caffeine family including theobromine and theophylline.

Caffeine is known to:

  1. help treat migraine headaches

  2. fight fatigue

  3. help improve mental function

Most of the proposed uses of guarana fall into line with these effects of caffeine although some scientists suggest there are other compounds in guarana that may have similar effects but the research currently doesn’t exist.

If you take a look at the majority of energy drinks and other products with caffeine, you may find guarana added along with stimulants like ginseng. When a caffeine containing product is enhanced with the herbal guarana you have a potential caffeine double whammy…that may or may not be fine for your body.

For someone who is caffeine sensitive or not use to caffeine, the effects of guarana by itself or added to the caffeine in coffee, energy drinks or other products may not be pleasant and could be dangerous:

  1. The heart rate and blood pressure jump up

  2. Feelings of panic and anxiety can set in at any age

  3. It’s hard to sleep

  4. Heartburn, gastritis

  5. Disturbances in heart rhythm

A typical dose of guarana supplies 50 mg of caffeine about half the amount in a cup of coffee. However, take a look at the label of most products containing guarana and the amount will not be listed. If you want to find out, check the website of the company who makes the product and look for the ingredient disclosure.

Young children, pregnant or nursing women, or people with heart disease or taking the medications we just discussed should not use guarana. So Moms, be aware of what your children drink, especially if they play sports of any type. Energy drinks are handed out like water but the effects are nowhere near the same.

What’s Your Salt IQ? Part 2: Cut the Salt but not the Flavor

salt-part2Shaking salt from your diet is constantly in the news. But, I don’t want to lose the flavor of my food, do you? Did you know that approximately seventy five percent of the sodium in the American diet comes from the various sodium products added during processing? Incredible isn’t it? So get your label sleuth glasses on… it’s time to read the fine print! Reading labels is key to finding all the hidden sodium. There are a lot of us checking out food labels according to a 2009 survey by Mintel. Over 25% of people responding are always watching salt in their diet.

Check out the sodium level in some of these notorious sodium offenders as the level really does vary company to company:

  • Sauces and salad dressings: consider making your own from a flavored balsamic vinegar and good olive oil
  • Frozen and canned veggies
  • Frozen entrees
  • Fast foods
  • Deli meats plus ham, hot dogs, sausage and bacon
  • Soup
  • Bouillon cubes

Because salt adds flavor to food, you might be wondering whether you’re going to miss all that added sodium. You’ll like this answer. Your taste buds will adapt after about 6-8 weeks of gradually cutting back on the amount of sodium that you consume.

More tips to shake the sodium but not the flavor in your diet:

  • It’s all about fresh…start with fresh ingredients when at all possible. Bonus! When you eat more fruit and veggies, the additional potassium has a positive or lowering effect on blood pressure.
  • Rethink your seasonings…pepper is great but try a wide variety of fresh and dried herbs/spices and delightful seasoning blends without added sodium. Use more lemon, lime and other citrus for flavor along with a variety of vinegars. Grow fresh herbs in pots to use in your dishes too.
  • Rinse tuna, canned beans and canned veggies to lower the sodium content. Add your fresh herbs and spices to kick up the flavor.

What’s your favorite trick to shake the salt? Email me and I’ll share some of your tips in my podcast.

Sweetener Update: Agave and Stevia

agave-picOne of the big trends in food is the move away from processed foods with chemical additives to more natural foods. Since there is no legal food definition for the word natural, let say it’s a movement back to foods closer to the way they exist in nature. This trend is true for sweeteners as well. There are many new sweeteners on the market as you notice every time you go to the grocery store. Let’s take a quick look at two ….agave nectar and stevia. Google and you’ll find loads of information but many times the hype is full of misinformation versus evidence-based science. Here’s the lowdown on these two sweeteners so you can separate fact from fiction.

Agave nectar also called agave syrup is a sweetener from the Mexican cactus. You will find it in all types of food products ranging from nutrition bars to drinks and desserts. It’s one of 2009’s trendy flavors and a trendy sugar alternative frequently used in cocktails. Agave has been touted for its delicate taste and is popular with chefs for use in desserts as well as to sweeten teas and health drinks. It’s one more choice to be included among honey, maple syrup, sugar and high fructose corn syrup.

Is agave better for you than any other sweetener such as sugar, maple syrup or honey? Agave is promoted as a low glycemic alterative for diabetics. Is it? If you’re diabetic or have friends or family members who are, you don’t want to miss this. Here’s why. Agave and sugar have approximately the same number of calories….about 16 per teaspoon. Agave is sweeter than sugar so you could save a few calories by the amount you use. Sugar is technically called sucrose which is composed of 50% fructose and 50% glucose when it is broken down in the body. Agave varies in its fructose content with a range from 55% up to 90%. It all depends on the processing method used which can affect the fructose content. Agave nectar with 55% fructose is about the same as high fructose corn syrup so there would be no benefit in agave at 55% fructose over sugar, high fructose corn syrup or honey from the standpoint of composition, only taste and personal preference.

The reason you hear …theoretically… agave nectar touted as safer for diabetics is that a higher fructose composition typically doesn’t cause dangerous spikes in blood glucose. Currently, we don’t have clinical studies as to agave’s safety in diabetes. Unless there is a label stating the exact percentage of fructose in the agave nectar, it can range as we just talked about from 55% up. So if you are diabetic, your blood glucose may or may not be spiked…all depending on how much fructose is in the particular agave product consumed and your particular case of diabetes. Plus fructose sweeteners may increase blood triglycerides if you have diabetes so be sure and discuss this with your health care provider.

Stevia falls into the noncaloric sweetener category. Stevia extract comes from the Stevia rebaudiana plant, an herb native to Central and South America. Stevia is 200-300 times sweeter than sugar with a slightly bitter aftertaste depending on the plant components used. This bitter aftertaste is the reason you may find stevia blended with other ingredients.

For example, some stevia products are often blended or ‘cut’ with a sugar alcohol called erythritol found naturally in vegetables and fruit so the product is less sweet than pure stevia. Erythritol is not metabolized or absorbed so it doesn’t spike blood glucose levels or cause the gas or bloating of some sugar alcohols like sorbitol or mannitol. Most of the products work well for people with diabetes but it’s smart to read the label and see what stevia is blended with and if the product has calories. Expect to see stevia used as a sweetener in many products and sold as a tabletop sweetener under various names.

Stevia and agave are just two of the many new sweeteners on the market. If you have diabetes, be sure and check the labels closely before you make a decision on which ones to try.
