colorful eating

Variety is the spice of life, and it’s time your plate matched this proverb. It’s likely your meals could use a makeover by practicing colorful eating.

Surveys show that a troubling majority of adults still don’t eat enough fruits and vegetables. In fact, as of 2013, 76 percent and 87 percent of adults did not consume the recommended daily intake of fruits and vegetables, respectively. That means most adults are missing out on the benefits of a plant-rich diet.

Diversifying your diet with colorful eating is worth it—for your palate and your health. Fruits and vegetables add more than splashes of vibrant color to your diet.

Each color represents different phytonutrients, or plant-derived micronutrients, that can support many systems in your body. So, colorful eating means helping to maintain your cardiovascular and immune system, your eyes, your brain, and healthy cellular communication.

The first step in reversing this deficit is to visually assess the colors on your plate. Ask if your meal looks monochromatic—all one color, like whites or browns. If it is, liven things up by adding in vibrant sides of in-season fruits and vegetables.

Adding color to your diet doesn’t need to be overwhelming. Since each color represents different types of beneficial compounds, any color will do. Below, your options are broken down by the colors of the rainbow. The sections will tell you more about what each color can offer. Lastly, you’ll have shopping suggestions to diversify the produce in your grocery cart and make colorful eating easier.

Red is for More than Roses

Red fruits and vegetables often contain beneficial compounds like carotenoids and flavonoids. These naturally-occurring compounds offer a range of health benefits when consumed regularly.

Carotenoids are a group of pigments synthesized by plants. Commonly found carotenoids include beta-carotene, luteinzeaxanthin, and lycopene. Many of these act as antioxidants in the body, helping to neutralize free radicals. This activity can help protect your cells and support your health.

Additionally, these carotenoids play an important role in good vision. Beta-carotene, for example, is also known as provitamin A. This means that the body converts dietary beta-carotene into vitamin A, or retinol. In the retinol form, it’s a necessary component of a chemical reaction—occurring in the retina—that ultimately helps with low-light and color vision.

Lycopene also deserves a closer look. When regularly eaten, lycopene has been associated with increased levels of antioxidant enzymes and reduction of oxidative stress. Furthermore, observational studies have shown promising data about a link between dietary lycopene and the maintenance of overall health.

To boost levels of lycopene in your diet, reach for tomatoes—fresh or canned. Get creative with how you incorporate colorful eating into your meals. This will keep you from getting bored. Some ideas include: caprese salad, tomato soup, and pasta with marinara sauce.

But there’s more to the color red than just lycopene. Red-hued foods contain vitamin C and phytonutrients, like flavonoids—which also act as antioxidants.

These phytonutrients aren’t restricted to food alone—they can also be found in beverages. So, if you enjoy the occasional glass of red wine, do so guilt-free! Red wine packs a punch when it comes to flavonoids and similar compounds—especially resveratrol.

What to buy: Consider spicing up your shopping list with a variety of red foods.

  • Vegetables: beets, red cabbage, radishes
  • Fruits: tomatoes, red grapes, strawberries, pomegranates, red bell peppers
  • Beverages: red wine, tea

Orange & Yellow—The Bright Side of Fruits & Veggies

Fruits and vegetables that are orange or yellow also provide carotenoids. The most common one found in orange and yellow plants is beta-carotene.

As mentioned above, one possible fate of beta-carotene is its conversion to vitamin A upon ingestion. However, when beta-carotene is not converted, the body uses it as an antioxidant.

Orange and yellow plants also offer essential vitamins and minerals—vitamin C, folic acid, and potassium. For example, citrus provides large amounts of vitamin C, an antioxidant and essential nutrient.

What to buy: Add the following to your grocery list to brighten each meal.

  • Vegetables: golden beets, sweet potatoes, corn, turmeric
  • Fruits: lemon, orange, tangerine, grapefruit, pineapple, cantaloupe, papaya

Going Green

Since you were a kid, you’ve probably heard something along the lines of “Eat your greens.” It doesn’t sound very exciting. But when you look at what these greens are packing, you might find them more enticing.

Green plants provide a wealth of carotenoids and essential nutrients in the form of vitamins A and K, and potassium. Leafy greens also offer a healthy dose of calcium. If that list doesn’t impress you, consider the fact that many green veggies are sources of glucosinolate. This compound is a precursor to isothiocyanates.

These are the compounds that give some vegetables a slightly sour, bitter, or “skunky” taste. But you should learn to love the flavor because of all their health benefits. They play a role in cell signaling, support your detoxification pathways, aid in the production of glutathione and have antioxidant activity.

You can get your fill by consuming cruciferous plants, or vegetables within the Brassica family. Broccoli, cabbage, cauliflower, and kale are some of your options. If you want the most bang for your buck, one group of researchers has shown that mustard greens and cabbage are particularly high in these beneficial compounds.

Also consider chowing down on spinach, kale, turnip greens, or collards if you want your plate to go green.

What to buy: Pick up a variety of these greens the next time you’re at the market.

  • Veggies: broccoli, bok choy, arugula, kale, Brussels sprouts, zucchini, asparagus, herbs
  • Fruit: apples, pears, green grapes, kiwi, honeydew melon, limes

These Blues (and Purples) Won’t Get You Down

Plants that are purple and blue in hue are rich in anthocyanin pigments. Anthocyanins are yet another group of flavonoids. These micronutrients act as antioxidants, primarily helping to protect cells and tissues from oxidative damage.

A group of researchers analyzed 15 fruits and seven vegetables to determine the content of these beneficial pigments in each. Of the blue and purple foods, the following had the highest concentration of anthocyanins: wild blueberry, elderberry, black raspberry, and eggplant.

What to buy: Next time you’re in the grocery store, add some of the following to your shopping basket.

  • Veggies: purple potatoes, purple cabbage, purple cauliflower
  • Fruits: prunes, figs, plums, grapes, eggplant, purple- or blue-colored berries

Color Outside the Lines with Colorful Eating

Understandably, it can be difficult to incorporate these items into meals for picky eaters or those pressed for time. However, you can employ some tricks to increase the amount of colorful eating you’re doing. And here’s a secret: they’ll taste good too!

  • Add mild-tasting greens, like spinach, into smoothies. If you’re averse to vegetables in a smoothie, offset the flavor with something sweet, like strawberries. Try milk and banana for creaminess, your greens, and frozen strawberries to keep it cool and thick. Blend and you’ll be well on your way to the recommended daily five cups of fruits and vegetables in one on-the-go meal.
  • Try a slightly healthier version of mashed potatoes by substituting one-third of them for steamed root vegetables, like carrots and turnips. Even cauliflower can serve as a substitute. Mash the mixture together with salt and a small amount of butter or a healthier alternative—like olive or avocado oil. This alternative will still be the creamy, starchy dish you know and love, but with more phytonutrients in the mix and a dash of fiber to boot. And limiting potato intake has been shown to be a good move for your weight.
  • Opt for a health-conscious dessert by subbing chilled coconut milk and your favorite berries for ice cream. Your sweet tooth will be satisfied and you’ll get a big dose antioxidants and flavonoids, too.

healthy breakfast

healthy breakfast

After a good night’s rest, you’re recharged and ready to take on a new day. It’s important to fuel your body with the energy it needs to get work done. Eating a healthy breakfast is your best bet and sets you up for your entire day ahead.

Even if you aren’t hungry in the morning, it’s a good idea to eat a healthy breakfast. And it can come in many shapes and sizes. But there are a few things you can do to maximize your morning meal.

Amp up the Protein

Protein is an important component of a healthy diet. Many scientific studies have shown that consuming a high-protein breakfast reduces the urge to snack on high-fat and high-sugar treats. Eggs, yogurt, and lean meats provide the fuel your body needs to make it through the day. These foods are rich in protein and provide long-lasting energy.

Your muscles also need protein to stay in shape. Your recommended amount of protein per day depends on your weight. It’s 0.8 grams per kilogram of weight (or 0.36 grams per pound). To find your number, multiply your weight in kilograms by 0.8 or your weight in pounds by 0.36. For example, if you’re 70 kilograms (155 pounds), you need to get at least 56 grams of protein each day to supply energy and maintain muscle mass. Divide your daily protein requirement by your number of meals to find how much protein you need for breakfast.

Plugging protein into your healthy breakfast can help throughout the day. You can fight your snack cravings and maintain your muscles by starting each day with a protein-packed breakfast.

Choose Low-Glycemic Options

The glycemic index is a measure of how quickly your body absorbs sugar. Sugar, or carbohydrates, are an important and essential part of a healthy diet. But you have to be deliberate in the carbohydrates you chose.

When you opt for high-glycemic options, your blood sugar quickly spikes. This isn’t healthy and your body knows it. As a response, it dumps a lot of hormones into our blood stream (the major one of course is insulin) to coax your cells to absorb it—quickly.

As a result, even more quickly than your blood sugar rises, it comes crashing down. This can result in low blood sugar (also an unhealthy circumstance). When this happens, you can feel tired and lose focus. The response is your brain telling you to eat something—and anything—quickly. As a result, you reach for the closest thing (snack), which tends to be an unhealthy option.

To break this high-glycemic rollercoaster ride, choose carbohydrates that are absorbed more slowly to keep your blood-sugar levels low. This will also help you keep feeling full for longer and will provide a longer-term source of energy for your body (and brain) to use. And because your blood sugar won’t come crashing down, you get hungry slowly and this gives you time to make healthy food choices for your upcoming meals.

It has also been shown that people who eat breakfast—and especially low-glycemic breakfasts—tend to eat fewer calories through the day.

Choose Whole Grains for a Healthy Breakfast

Now that you have the protein taken care of, let’s help you chose the healthy carbohydrates in your breakfast. Here you want to focus on fiber. That’s because it aids in digestion and keeps you feeling full after a meal.

Whole grains have higher fiber content than their refined counterparts and are better for you. By choosing whole grains, your body can help maintain steady blood sugar and avoid sudden spikes or drops. Whole grain foods help maintain healthy cholesterol already in the normal range and support heart health.

Phytonutrients (nutrients derived from plants) are also abundant in whole grains. They’re important because your body can’t make these essential compounds. Eating whole-wheat toast, or whole-grain cereals can increase the fiber and phytonutrients in your diet and will help you stay full throughout the day.

Skip the Juice, Go with Fruit

Fruit juice is a tempting choice when preparing breakfast. Unfortunately, these drinks are high in sugar, low in fiber, and associated with negative health effects.

So, juices aren’t the best choice for a healthy breakfast. Going with whole fruit is more nutritious. Whole fruit can satisfy a craving for sweets and has the added benefit of fiber, which helps support healthy digestion.

Some of the best fruits to eat at breakfast are berries, grapefruit, and bananas. Berries are loaded with antioxidants and help maintain cellular vitality. Grapefruit is full of fiber and can fill you up faster than pastries and sweet drinks. Bananas are packed with potassium, vitamin C, and other vitamins and minerals. These micronutrients help maintain a healthy body and sustain you throughout the day. And bananas are easy to grab and take with you when you’re in a hurry.

Be Smart About Your Fat Selection

Fat isn’t a bad word. It’s one of the essential macronutrients and provides a great source of sustained energy. Fat can even help you feel full longer. But you have to be selective about the type of fat you choose and be careful about the extra calories they add.

That’s because not all fats are created equal. Trans fats—like margarine—should be avoided altogether. For other fats, you should first consider the source.

An avocado and a pork sausage patty both contain fat. But it’s pretty easy to guess which one is better for your body. As a general rule, fats that come from plants are usually healthier and fats that come from animals are usually less healthy.

So, don’t skip the fat. Just be smart about your selection.

What You Drink Matters

When you find yourself in need of a morning beverage, look to water, coffee, and tea instead of caffeinated soda, juice, or energy drinks—even so-called “diet” options. These sugary beverages can spike blood sugar, dehydrate your body over the course of the day, and in the case of diet beverages, even trigger you to snack more.

Water provides lasting hydration and helps your body function optimally. Tea and coffee are natural sources of energy boosting caffeine and have been shown to activate the areas of the brain that keep you alert and focused. Green, white, black, and herbal teas are also valuable sources of phytonutrients and antioxidants. These compounds are important for supporting healthy cell and immune function.

Pair Your Favorite Healthy Breakfast with Nutritional Supplements

Even when you try to eat right, your nutrient supply can fall short of your daily needs. Multivitamins are quick, easy ways to ensure your body has all the vitamins and minerals it needs to keep your engine running smoothly.

Nutritional supplementation, as recommended by your healthcare provider, helps close the gap between what your body needs and what your diet provides. Supplements can optimize the efficiency of your cellular communication, help support your immune system, and help you turn the macronutrients you just ate (protein, carbohydrates, and fats) into the energy your body needs for the day.

Start your day with a healthy breakfast and a multivitamin to put your body in the best position for success.

Easy Ways to Make Better Breakfast Choices

Eating a healthy breakfast doesn’t have to be difficult. Small changes and substitutions to your current breakfast routine could be enough to improve your morning nutrition.

Here are some simple ways to have a better breakfast today:

  • Substitute white bread with a whole-grain alternative.
  • Try to avoid most cold cereals. Even what looks to be the healthiest choice tends to be high glycemic.
  • Drink tea or other healthy beverages instead of juice. If you need to sweeten, use natural sweeteners like stevia or agave nectar.
  • In a hurry? Make sure your on-the-go breakfast includes a fruit/vegetable, protein, a smart fat, and whole grains. A piece of fruit, hard-boiled egg, and whole-wheat bagel will fill you up, fuel your busy day, and help you make smart eating choices later on. Or alternatively, a low-glycemic meal replacement shake can be quick, healthy, on-the-go option.
  • Take a multivitamin at breakfast each day. After you make it a habit, taking your vitamins will be easy to remember.

fruits vs vegetables
nutrition facts labels

nutrition facts labels

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.

deficiencies

deficiencies

You’ve heard it before: you can get all the nutrients you need from the food you eat. Well, maybe you can. It’s certainly possible. But it’s unlikely.

We all know that vitamin supplements are no substitute for a healthy diet. But nobody is a perfectly healthy eater. It’s hard to get everything you need if you’re ill, a picky eater, dieting, or have food allergies. For those on restricted diets it can be particularly challenging.

Research has shown that deficiencies also vary by age, gender, or ethnicity. And deficiency may soar to nearly one third of certain population groups. In addition, many people are too busy to take the time to eat well or cook at home.

Luckily, there’s something you can do to help prevent deficiency. New research shows daily multivitamin/mineral supplements may be a nutritional insurance plan.

A new study in the journal Nutrients analyzes data from 10,698 adults age 19 years and older. The data comes from the 2009-2012 National Health and Nutrition Surveys (NHANES). This provided reliable 24-hour dietary interviews—including the use of dietary supplements. An in-person health examination also collected blood samples to analyze markers of nutritional status.

They found the daily use of multivitamin/mineral supplements helped prevent shortfalls in important nutrients necessary to support overall health. There were a few exceptions: calcium, magnesium, and vitamin D. But those are still important nutrients everyone needs to get enough of.

“Regrettably, there appears to be a great tenacity to old ways of thinking, e.g., you can get all the nutrition you need if you just eat a healthy, balanced diet—and then ignoring how most people actually eat and what they actually require,” lead author Jeffrey Blumberg, PhD said. “… Also, as our understanding about higher nutrient requirements of optimal health and wellness grows, particularly among older adults, it is clear that it can be quite difficult to achieve these intakes of selected nutrients from commonly available food choices.”

Now when someone says, “you can get everything you need from your diet,” you can point them to this study.

Health Benefits of Nutritional Supplements

Blumberg JB, Frei BB, Fulgoni VL, Weaver CM, Zeisel SH. Impact of Frequency of Multi-Vitamin/Multi-Mineral Supplement Intake on Nutritional Adequacy and Nutrient Deficiencies in U.S. Adults. Nutrients. 2017;9(8)

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.

Patients with mental disorders are often deficient in omega–3 fatty acids, B vitamins, minerals, and amino acids that are precursors to neurotransmitters.

About 10-20% of the population experience mental health conditions each year, including depression, anxiety, bipolar disorder, schizophrenia, and post-traumatic stress. Research shows that nutrition can influence mental health.

According to a published review of nutrition and mental health, the most common nutritional deficiencies seen in patients with mental disorders are of omega–3 fatty acids, B vitamins, minerals, and amino acids that are precursors to neurotransmitters.

Although the connection between nutritional deficiencies and physical illness is better understood, fewer people are aware of the connection between nutrition and mental health. Many dietary patterns that precede depression are the same as those that occur during depression. These may include poor appetite, skipping meals, and a dominant desire for sweet foods. Nutritional neuroscience is an emerging discipline shedding light on the fact that nutritional factors are intertwined with human cognition, behavior, and emotions.

This is not meant to imply that a particular nutrient or nutrients can cure or prevent all mental illness, simply that there is a connection between mental health and many nutrients, including carbohydrates, protein, omega-3 fats, B-complex, vitamin B12, folate, calcium, chromium, iron, selenium, iodine, zinc, and mental health. Good nutrition plays a significant role in overall brain health. And poor nutritional status may negatively influence brain health, mood, depression, etc.

Note: Discontinuing appropriate medications or therapies is not recommended without specific advice by a health professional, but making sure that you get all the nutrients you need to support mental health is always recommended.
