You don’t have to memorize the nutrient content of all your foods. You can thank nutrition facts labels for that. It isn’t necessary to recall the sodium content of your breakfast cereal off the top of your head every time you shop. But getting the most information from reading nutrition facts labels can be tough, too.

Here’s six tips for pulling out the facts that matter most to you:

Start with the Serving Size

Every number on that nutrition facts label means nothing without some context. The serving size provides the context you need.

All the amounts that follow are based on that servings size. Sometimes the whole package of food is a serving, but that’s not always the case. That’s why you have to be careful.

Relying on the label’s serving size is a good idea because you can’t trust your judgment. It’s not an insult to you—in general, people are terrible at gauging serving sizes. Research indicates the average person’s estimations are off somewhere between 40-150 percent. So, you could be eating double the number of calories you think you are.

Please fight the urge to skip right to calories or fat content. Don’t start down the label without checking the serving size to put everything else in context.

Figure Out the Type of Fat

Reading nutrition facts is often a dive into the macronutrient content of the food. That’s a helpful way to break things down and give you the information you need. But the raw numbers might not be enough to make good decisions.

This is especially true with fats.

Paying attention to the type of fat and where that fat comes from can be more important than the total number. You want to avoid trans fats, but saturated fat can be more nuanced. That’s why you need to look at the ingredient deck to figure out if the source of fat is vegetable-based (usually healthier) or animal-based (usually unhealthier). Going the extra step will help you make the healthy determination.

Check the Sugar and Find the Fiber

Fats aren’t the only macronutrient that requires extra investigation. When you’re reading nutrition facts labels, look at carbohydrates, but also note the sugar and fiber amount.

Sugar is a simple carbohydrate. It has well-established ties to weight gain and can hide in foods that seem healthy. Just think about all the sugar that’s hidden in fruit juice. Checking the sugar content—especially added sugar—is important.

While you might avoid sugar, your diet can benefit from more fiber. These complex carbohydrates aid in healthy digestion and keep you feeling full for a longer time. And you only absorb about half of fiber’s calorie content. All these combined effects help fiber support your weight-maintenance efforts. Make sure to find the fiber when reading nutrition facts labels.

Pay Attention to Protein

Just because it’s the final macronutrient mentioned doesn’t mean protein you should ignore it when reading nutrition facts. Far from it. If you’re managing your weight or exercising, protein is key.

A lot of studies have shown dietary protein’s ability to support weight-management programs. An analysis of 51 studies found that a sufficient increase in protein—over 58 percent per day, on average—showed favorable weigh-management results.

A similar analysis showed that dietary protein increases showed favorable effects for muscle and strength during resistance training.

So, protein is a big plus for those focusing on diet and exercise. But it’s also important for general health. Dietary protein provides the essential amino acids your body needs to carry out its daily functions.

Don’t Miss the Micronutrients

The essential vitamins and minerals are listed on the label. This will help you see how much nourishment you’re actually getting from what you’re eating.

On most labels, you’ll also see a percentage of daily value. That number is based on recommended daily allowances, which are about avoiding deficiencies. It doesn’t consider optimal amounts needed to live your best life.

Sodium is one micronutrient you won’t find with the other vitamins and minerals. It’s typically listed with the macronutrients. And if you’re watching your sodium intake, check this important number.

Keep Your Health Goals in Mind

Every person is different. Everybody has different health goals. That makes each label look different to each individual.

You have to look at labels through the lens of your own health goals. When you do that, each number starts to take on new meaning. Here’s one example: if you’re managing your weight, a low-calorie count might be intriguing. But if you’re a body builder, high calories might be more important.

And don’t lose sight of the big picture. Put what you’re about to consume in the context of what you will or have eaten over the course of an entire day. Think of nutrition as a daily bank account. What have you put into your nutritional savings account and what will you be withdrawing?

Reading is Fundamental

Get in the habit of reading labels and learning about the nutritional composition of your food. Over time this becomes easier and eventually will become second nature. You’ll never have to memorize every detail. But at some point, you intuitively begin to know the nutrient content of the food choices in front of you. Educating yourself will help you reach for healthier alternatives to fuel your life.

This is all part of getting serious about your food. In coordination, you should write down your health goals. Then ask how you want food to fuel your life, and what ratios of macronutrients (carbs, proteins, and fats) make you feel the best and help you achieve the health you desire? After you have your health goals, utilize a nutrition facts panel to help you achieve them.

But, remember, there is still no substitute for eating as many fruits and vegetables as possible, exercising, choosing healthy sources of protein, and ensuring you get optimal amounts of all essential micro- and macro-nutrients your body needs for optimal health.

That’s an old adage. But what does it really mean?

Basically, everything that makes up your physical body came in through your mouth. You are literally made-up of the things you consume—the good, the bad, and the ugly. So the sum of your diet, the water you drink, and your nutritional supplements make up you.

But that is only part of the story.

In a new study done at USANA Health Sciences and published in the journal “Nutrients”, scientists have shown that what you eat (or drink) can have a significant impact. It can actually affect how your genes are regulated—whether they are turned on or turned off.

Advantages of whole fruits and juices

Observational and epidemiological evidence shows consistently that consumption of fruit promotes good health. Eating whole fruits has generally been recommended by health experts as preferable to juice, although juicing and juice products are often seen as a part of a healthy diet plan.

Whole fruit has an advantage in weight control and glucose regulation due to its fiber content, and greater bulk and satiety. Juicing has some advantages as far as convenience, availability year round, rapid rehydration, and variety (people often get more variety in their fruit intake through juicing than they would otherwise get through whole fruits). Even with these differences, it has always been assumed that whole fruits and unprocessed juices are nutritionally equivalent.

New research shows whole fruit and juice affect health in different ways

New research by scientists at USANA Health Sciences, Inc. has uncovered another interesting difference between whole fruits and fruit juices. It turns out they may actually confer different health benefits by influencing health and the immune system in different ways. This study found that subjects who consumed whole fruit versus fruit juice had significantly different chemical signatures (known as methylation or the epigenome) on specific regions of their DNA.

Epigenetics is the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. Epigenetic change is a regular and natural occurrence. But it can also be influenced by several factors including: age, the environment/lifestyle, and disease state.

One way to illustrate the meaning of epigenetics is with identical twins. Both twins possess identical DNA, or genetic code. But, they are not exactly the same, and differences become even more obvious with age. This is due to individual variations in diet, lifestyle, environment, disease state, and other factors that influence the way their cells read the genes.

In this study, the epigenetic signatures (the chemical code that allows genes to be turned off and on) of whole-fruit consumers were enriched in genes near specific pathways. These pathways were those associated with improved immune function, chromosome integrity, and telomere maintenance. But the same signatures of fruit-juice consumers were enriched around genes associated with pro-inflammatory pathways.

The authors point to the fact that whole fruit is rich in natural fiber as a reason for this difference. Fiber is removed during the juicing process.

“The epigenetic differences observed in our study may be attributable to variation in fruit fiber content between fruit and juice,” the study states. “Fiber, a largely indigestible molecule, alters the digestion rate of co-consumed nutrients and thus influences the intestinal location and mechanism by which fruit derived nutrients are absorbed and ultimately processed. Much of this variation in intestinal absorption is likely due to variation in breakdown of nutrients by intestinal microbiota”.

Conclusion

The paper goes on to conclude that, for the first time, juice and fruit consumption are correlated with different influences on gene expression. Additionally, the analysis shines new light on the molecular mechanisms that drive the interactions between our diet, target cell signaling molecules, and epigenetic pathways.

In a follow-up interview, senior author Dr. Robert Sinnott emphatically stated that “clearly eating whole fruit versus consuming fruit juice confers different health benefits. Giving children sippy cups of juice rather than cubed whole fruit are not nutritionally the same.”

Co-author Jessie Johnson, Ph.D. had this to say about the larger implications of the study: “Understanding how nutritional intakes from whole foods, to beverages, to nutritional supplements activate cell signaling pathways, modulate cellular physiology, and ultimately improve human health will be a major breakthrough in further personalizing individual nutritional needs.”

Traditionally, dietary nutrients have been looked at in a few different ways. They’ve been seen as building blocks for a protein, co-factors for enzymes, structural components of the body such as bones, or as individual antioxidants that help quench free radicals. But it is much more complicated than that. Dietary nutrients and compounds also influence the way our cells communicate, and how our genetic code is expressed.
