High Fructose Corn Syrup, Leptin and Weight: Avoiding the Slippery Slope

Recent media ads informing you HFCS (high fructose corn syrup) is safe might lead you to believe consuming a soft drink made with HFCS poses no health risks. When you look at the current research, nothing could be further from the truth.

To understand the truth, we need to look a little at the chemistry of different sugars and hormone interactions. HFCS was developed in the 70’s from cornstarch that is made from genetically modified corn. This process results in a product that is less expensive than sugar, and is used by the major food companies to sweeten their products – anything from sodas to jams, ketchup, juices, and processed packaged foods.

Table sugar is composed of 2 sugars – glucose and fructose. All the cells of our body can readily metabolize glucose, but fructose is only metabolized via the liver. Large amounts of fructose going to the liver causes fatty liver leading to high cholesterol and triglycerides.

Since HFCS contains more fructose than sugar, the fructose is more readily available since it is not bound up with glucose, as is the case with natural sugar. Therefore it has a straight shot to the liver.

Now enter the hormone leptin. Leptin is one of the main hormones regulating appetite. I like to state that leptin lowers your appetite. Several recent studies revealed a diet high in HFCS increased the level of triglycerides, which blocked the brain’s response to leptin.

Therefore, if your body becomes insensitive to leptin, and in fact, develops a leptin resistance, the brain will continue to signal your body it needs more food and continue to store fat.

Judith Altarejos, Ph.D. a researcher at Scripps states “obesity results when the brain becomes ‘deaf’ to the leptin signals.” If your brain is continuing to tell you to eat, you will have a hard time losing weight.

Turning this situation around is not as hard as you might think. Consuming protein at each meal and snack, along with healthy sources of carbohydrate like fruits, vegetables, nuts and seeds and healthy fats will do wonders for turning on the leptin switch. Keeping refined processed sources of carbohydrate out of your diet is essential and necessary to keeping or restoring balance to the body.

So look for HFCS on labels and stay clear of the slippery slope. Your body and arteries will thank you.

What About those Snacks?

In this morning's LA Times Family Circus cartoon Billy asked his Mom "how much of a snack do I get to eat before it becomes a meal?" This question comes up frequently with clients. Is snacking okay? How many calories constitutes a snack before it becomes a meal? Is it okay to snack, or am I supposed to wait till the next meal?

Snacking is an important part of eating. If you go more than 5 to 6 hours between meals it is essential to have a snack to prevent a drop in your blood sugar or overeating at the next meal. The size of snacks depends on your activity level, weight, and age. In general, snacks fall in the 200-350 calorie range while meals are over 500 calories.

Examples of healthy snacks are:

1. 1 ounce of raw or unsalted dry roasted nuts (about 15-20) with a medium piece of fruit


2. 1-2 slices of cheese with and medium piece of fruit


3. 1-2 tablespoons of natural peanut butter with fruit or celery


4. 1/4 cup of guacamole with cut up vegetables


5. 1/2 cup of plain yogurt or cottage cheese with nuts or nut mix (below)

My upcoming nutrition book with recipes has a healthy delicious nut mix that is a flavorable topper for plain yogurt or cottage cheese, and works well by itself for a snack.

Healthy Nut Mix

Serves: 10 ¼ cup servings

¼ cup raw steel cut oats
½ cup of raw pumpkin seeds
¼ cup of raw sunflower seeds
¼ cup of unsweetened dried coconut
½ cup of coarsely chopped raw cashews
¼ cup of sliced raw almonds
1 teaspoon of ground cinnamon
1.5 tablespoons of extra virgin coconut oil
1 teaspoon of honey

Instructions:

Mix all ingredients together and spread on cookie sheet. Bake at 350 degrees till golden brown, about 20 minutes, stirring once through the cooking process. Remove from oven and let cool on the cookie sheet. Store in airtight container for up to 5 days or in the freezer for a month.

So thank you Billy for posing the question for our blog today and no need to feel guilty about snacking. It is important to health, vitality throughout the day, and reasonable eating!

Ode to Peanut Butter!

Peanut butter is my all time favorite food so I thought it appropriate to start my first blog with peanut butter talk. Many think of peanut butter as the usual kind in the grocery store, but many natural peanut butters or other nut butters now exist which taste amazing and have a much better flavor and consistency than in times past.

Peanut butter is a great snack to have on apples, bananas, or celery in the afternoon or evening. I think it gives you feeling you have had something decadent and healthy at the same time. Natural nut butters are packed with monounsaturated fat, which is the healthy fat that decreases incidence of heart disease by increasing your HDL or happy cholesterol. HDL is the cholesterol level you want to be high since it gets rids the body of bad cholesterol!

Two of my current favorite peanut butters are "Cream-Nut" which is a natural peanut butter by Koeze Company, a family run business in Grand Rapids, Michigan. Several of the Whole Foods in West Los Angeles sell this brand but you can also find it online.

My other current favorite peanut butter is a new one available at Trader Joe's called "Valencia Peanut Butter with Roasted Flaxseeds." The flaxseeds make it like you are eating a great peanut butter with toffee bits in it. Trader Joe's also sells a natural cashew nut butter and a cashew macadamian nut butter. One of my clients calls the cashew nut butter "dessert on a stick."

So the new blog is now launched. Stay tuned for postings on my favorite new foods products and the most recent studies on food and health. Feel free to ask questions on topics that are of interest to you.

Bon Appetit!
