Obesity and Liver Disease in the Hispanic Community

Posted: 09/14/2012 6:20 pm

A combination of heredity and diet is driving a potential health crisis of liver disease in the Hispanic community.

Obesity is a growing problem among Hispanics, especially children and adolescents. In Los Angeles County, obesity levels among Hispanics are among the highest (25.5 percent), especially hitting those with low incomes. In some communities, some 35 percent of children are obese.

Obesity is closely associated with non-alcoholic fatty liver diseases, which can range from simple accumulation of fat in the liver to irreversible scarring, a condition known as cirrhosis. Excess fat in the liver can lead to the development of Type 2 diabetes, a chronic disease, and over time to liver failure, cancer and death. In Los Angeles County, liver disease is the fourth leading cause of death among Hispanics men.

Particularly worrisome is that levels of liver fat are increasing among obese Hispanic children and adolescents. Fatty liver disease, an ailment traditionally associated with middle age, has become more evident in Hispanic youth. A study done by the USC Childhood Obesity Research Center found that 38 percent of obese Hispanic children and adolescents in Los Angeles have liver fat levels indicating the presence of nonalcoholic fatty liver diseases.

Mounting evidence suggests that Hispanics are genetically predisposed to fatty liver disease, compounding the health risks. An estimated 49 percent of the Hispanic population, compared to 23 percent of whites and 17 percent of blacks, carry a gene associated with higher liver fat content up to twice normal levels. Imaging studies show that the effect of this gene can be observed in Hispanics as young as 8 years old.

Combine this genetic predisposition with Hispanics' increased consumption of sugar -- especially of fructose -- and you have the makings of a health crisis.

Fructose, also known as "fruit sugar," naturally occurs in most fruits. In this form, the sugar is safe for humans because the fiber-rich flesh of most fruits slows down absorption of fructose as the sugar breaks down.

There are no such protections in a relatively new source of the sugar: high fructose corn syrup, which is made from highly processed cornstarch. High fructose corn syrup is now the preferred sweetener in the food industry because it is much cheaper to produce and much sweeter than ordinary table sugar. It is also increasingly added to many processed foods and is found in bread, cookies, breakfast cereals, chips, yogurt and sports drinks.

Here's the problem: Fructose is quickly converted into fat in the liver, setting the stage for fatty liver disease when consumed in abundance. Complicating matters is that we really don't know how much fructose is present in foods and drinks because high fructose corn syrup can have varying levels of the sugar. In a recent study, we found that in some soft drinks, especially popular drinks like Coca-Cola, Sprite and Pepsi, levels of fructose were 20 percent higher than expected and 30 percent higher than if they were made with ordinary sugar.

What should be done?

National industry standards should be toughened to require disclosure of more information on food labels. Currently, manufacturers are only required to disclose high fructose corn syrup as an ingredient; they do not have to reveal the exact amount of fructose in their products. That's problematic because of the known risks of consuming too much fructose.

In the absence of specific label information, Hispanic parents should limit their children's overall sugar consumption. Even table sugar, or sucrose, is 50 percent fructose. And they should avoid any drink, cereal, bread, infant formula, baked good and so on whose label says it contains high fructose corn syrup, especially if their children are obese or overweight. The fructose content in high fructose corn syrup can be as high as 65 percent.

Adults, of course, should be equally vigilant about what they consume.

Public health officials also have a role to play. They should culturally tailor educational programs for the Hispanic community about the dangers of overconsumption of sugar and high fructose corn syrup in particular. In addition, health officials should launch a genetic-screening program to identify Hispanics, especially the young, predisposed to develop fatty liver diseases.

This is another problem we will have with the illegals,,,,,paying for all their health care and the twenty kids they all have

I think that many of these problems are related to Native American ancestry in some Hispanic groups. The incidence of obesity, liver disease, diabetes, and alcoholism in these populations in the United States is well documented and probably reflects a genetic propensity. Combine this with poverty and a poor diet and it is a recipe for disaster. I look "white" but have noted many of the same issues in my mixed-ancestry family.

For many many parents, food and love are put together as one. Children are rewarded with food, usually fatty types, if they are "good". Staying inside, and watching T.V., movies, games, etc plus eating snacks add to fat on the body. It is a way of eating and being inactive that adds the pounds.
Some people think "heavy" kids are cute and do not look to the consequences that may happen down the road. This isn't just for one culture, it is for all peoples.

I think the problem is that many immigrants don't know how dangerous processed food is. That food should not be eaten at all, not even in moderation. Combine that with poverty, and you have a recipe for disaster.

Food IS love when you're the one to prepare it for your family. That's how it's always been in my family. But then, we had a mediterranean inherited diet.

So, obesity and liver disease is higher among those that speak Spanish. Hispanic is not a race. The Article refers to Mexicans which have nothing in common to Cubans, Puerto Ricans or the rest of Central and South American people other than the language. Also, their diets are totally different. Food consumed by Latin Americans in the USA varies according to the country where they are from.

The article did not say anything about Mexican. It said Hispanics. I don't buy the genetic argument. If you control for poverty, you will see the same problems in poor whites.

Poor people eat too much processed food because it's cheap, and that's why they gain more weight and get disease.

Very good point! Genes do not come with language and what Americans call Hispanic is a diverse group
06:54 PM on 09/15/2012
It's not just about latinos, its about the american diet overall, heavily dependant on processed foods, GMO grains/HFCSs and other additives/chemicals. All foods should be labled properly, and prominently, in plain english - not "red #5" but ground beetles, bug spit, wood fiber, or whatever it actually is. Go ahead, real lables, then come home to your computer, and look up those ingredients, see what it is you are actually eating, is it "food"?

Correct absolutely on the money.

I am always astounded at the huge quantities of soda purchased by Latinos. Literally, shopping carts with nothing but 12 packs of soda.

Parents who love their children should start reading labels and reduce or eliminate HFCS as soon as possible!
