Health Foods are Healthy Because of the Nutrients They Provide Your Body

Advice about health foods is absurdly confusing.

Healthy diet information is a labyrinth of conflicting opinions and unsubstantiated “facts.” 

Almost every blog, article, and academic paper is chocked-full of the same buzz-words and witticisms, even though the advice given about what to eat – and what not to eat – varies wildly.

Discerning the facts of healthy foods from the fictions can feel impossible. 

And worse of all, there’s too much talk about food!

Focus on Nutrients, Not Foods

Food experts tell us what health foods we should eat, but rarely why. 

Likely, you already know why to eat some foods and why others have little to no dietary value: nutrients.

While you may already know nutrients give food its value, you probably don’t know a great deal about them. What you do know about nutrients probably consists of nebulous, overused catch-words like:

  • Calories.
  • Building blocks.
  • Antioxidants.
  • Chemical processes.

Likely, you know that bananas and tomatoes contain potassium, aloe vera contains vitamin E, that oranges and bell peppers have large amounts of Vitamin C, dairy products contain calcium, and that carrots have Vitamin A.

Also, you probably know that Vitamin A helps your eyes.  Vitamin E helps your skin. Vitamin C is an antioxidant. And potassium is “one of the most important minerals in your body,” even if you don’t know what it does.

In other words, you probably know the basics about nutrition.

Most people know a little about essential nutrients like vitamins, minerals, amino acids, carbohydrates, and fats. But the majority don’t know very much about the specifics of nutrients and nutrition.

The reason, there simply isn’t much information on the specifics of nutrients.

Health foods Don’t Make You Healthy, the Nutrients in Foods Do.

More important than knowing what foods to eat is knowing what nutrients foods provide.

It is essential to know which nutrients do what for our bodies. 

Then, you can decide which foods that have those nutrients you want to eat.

The essential and non-essential nutrients – and the amounts of those nutrients we consume – play a significant role in whether or not we are healthy.

If we know what nutrients we need, we can decide what foods we eat.

The following article will outlines:

  • The essential nutrients you need.
  • Non-essential nutrients aren’t necessary but are healthy.
  • Essential nutrients can be harmful if you consume too much often.
  • Non-essential nutrients will set back your weight loss objectives and health.

If you know what essential and non-essential nutrients are in foods, you can decide for yourself what foods are healthy! 

Essential Nutrients: Vitamins, Minerals, Proteins (Amino Acids), Fats, Carbohydrates, Oils, & Water

Healthy Foods six Essential Nutrients

The vitamins, minerals, proteins, fat, amino acids, carbohydrates, and water in foods determine a food’s value to your health. That is to say, the essential nutrients in food — and the lack of unhealthy, nonessential nutrients — is synonymous with that food’s healthiness.

All non-processed foods are a combination of essential nutrients and non-essential nutrients. For that reason, unprocessed foods are typically the healthiest.

Essential Vitamins You Require Daily

On their own, vitamins can not accomplish a great deal. For that matter, nor can minerals. 

But together, vitamins and minerals manage everything from bone density to the strength at which your heart beats. 

Vitamins and minerals stave-off disease and inoculate diseases already affecting your body. Together, vitamins and minerals maintain the efficiency of your digestive system and help you pass waste with ease.

Vitamins and minerals can boost your energy levels as well as give you greater endurance.

And, vitamins and minerals help your brain function. They can minimize depression and make you happier.

Also, vitamins and minerals can increase your libido!

The following are the 14 essential vitamins and what they do and what foods you can find them in!

Healthy Foods Amino Acids

Amino acids are the building blocks of proteins. 

Like every other essential nutrient, getting the right amount of each essential amino acid is critical for your physical and mental health. 

Not all amino acids are the same. Different amino acids accomplish different functions and serve as building blocks for different parts of your body. 

The following are the nine (9) most common — and essential — amino acids to consume daily. Your body requires 20 different amino acids. But, it produces 11 of them on its own when supplemented with the proper nutrients.

****While taking particular amino acids may be required to combat certain diseases or promote health, only take single-amino-acid supplements after consulting your doctor.****

Isoleucine (Branched Chain Amino Acid)

What Isoleucine Does for Your Body: Though it’s an amino acid, isoleucine boosts energy and endurance. The reason being, isoleucine plays a role in hemoglobin development. Keeping blood/sugar levels steady also requires isoleucine, and it is also essential to the development of lean muscle mass and muscle development as a whole.

What Lysine Does for Your Body: According to Medical News Today, lysine is not only a building block for the proteins that constitute your muscles and tissue. Lysine also helps your body absorb essential minerals like calcium and zinc. Additionally, it creates enzymes that are active components in your immune system. 

And, lysine helps your body generate collagen.   

How Much Lysine You Need: Per kilo of weight, your female body requires 38 mg of lysine per day. Children require substantially higher amounts.

Foods with the Most Lysine: Penn State’s Milton S. Hershey Medical Center says red meat, pork, and poultry have the most lysine. But cheese, especially parmesan cheese, has substantial amounts as well. Cod, sardines, eggs, and soy also contain lysine.

  • Dopamine.
  • Thyroid hormones.
  • Norepinephrine.
  • Epinephrine.
  • L-dopa
  • Tyrosine. 

And doctors prescribe phenylalanine to treat depression. The reason being, our bodies convert phenylalanine into norepinephrine. That, according to Penn State’s Milton S. Hershey Medical Center.

How Much Phenylalanine You Need: Daily, the female body requires 33 mg per kilo of weight and up to 45 when pregnant or lactating.

Foods with the Most Phenylalanine: Tuna, red meat, dark & white meat chicken, grouper, salmon, snapper, and cod all contain at least 200% of the necessary quantity of phenylalanine required per day. Pinto, white, navy, kidney, and black beans all have 100% or more of the daily amount needed of phenylalanine per cup. 

Dairy, in amounts of 16 ounces or more, all contain at least 50% of the required amount. Almonds, pistachios, peanuts, sunflower seeds, hemp seeds, and chia seeds all have at least 30% of the RDA per 1 ounce.


What Threonine Does for Your Body: Like several other essential amino acids, threonine is required by your body to create other amino acids. Namely, threonine is the primary ingredient needed for your body to develop serine and glycine, two amino acids essential for the building of muscle. 

Also known as L-threonine, this amino acid is also necessary for your nervous system, liver function, and digestion.

How Much Threonine You Need: For each kilo of body weight, a woman requires 20 mg of threonine per day. 

Foods with the Most Threonine: Almost any unground red meat, most store-bought fish, lamb, turkey, deer & elk, buffalo, soy, pork, cheese, and clams are all contain more than 100% of the required daily amount of threonine per 100 grams. Almost any type of bean will have at least 50% as well.


What Tryptophan Does for Your Body: Tryptophan plays a significant role in the creation of serotonin, a critical neurotransmitter associated with quality of sleep and a pleasant mood. Also, the body uses tryptophan to produce niacin and melatonin. 

How Much Tryptophan You Need: You require 5 mg of tryptophan per kilo of weight — as a woman — per day. 

Foods with the Most Tryptophan: Oily fish high in Omega-3, like salmon, are typically high in tryptophan. Chicken, spinach, and eggs are also high in tryptophan. So too are nuts and soy.

Types of Fatty Acids

Healthy Foods Oils

Monounsaturated Fats 

Olive oil is the most well-known example of monounsaturated fat. However, avocados, hazelnuts, and almonds are other examples of monounsaturated fats. At room temperature, monounsaturated fats are liquid. Monounsaturated fats should be consumed fresh or cooked at low heat to prevent them from going rancid.

Polyunsaturated Fats

Healthy Foods Healthy Fats

There are four types of polyunsaturated fats. Most people in the U.S. get sufficient amounts of omega-6 fatty acids. However, it is not uncommon for people in the U.S. to have an insufficient quantity of omega-3 in their diets. The four types of polyunsaturated fats are: 

  1. Alpha-Linolenic Acid (an omega-3 fatty acid).
  2. Linoleic Acid (an omega-6 fatty acid).
  3. Docosahexaenoic Acid (an omega-3 fatty acid)
  4. Gamma-linolenic Acid (an omega-6 fatty acid)

Saturated Fats

A large number of metabolic functions require saturated fat. However, large quantities can be unhealthy and lead to cardiac issues. Saturated fats are different than unsaturated fats because at room temperature, saturated fats exist in a solid-state. The name “saturated” comes from the fact that each carbon atom in a saturated fat molecule connects to two hydrogen atoms. 

Types of Carbohydrates

Healthy Foods carbs

All carbohydrates are one form or another of saccharide. The simplest saccharides are monosaccharides. Simple sugars are monosaccharides. The most complex carbohydrates are polysaccharides, like starch. Disaccharides are generally thought of as the healthiest carbohydrates because they are neither simple nor heavy. 


Fructose – One of the highest calorie saccharides, fructose is in soda, milk chocolate, candy, bbq sauce & salad dressing. Table sugar is fructose. 

Glucose – Though glucose occurs naturally in foods like bread, rice, pasta, and potatoes, the human body converts all other carbohydrates into glucose. Medical News Today explains, ‘”Blood sugar” means “glucose in the blood.”’

Galactose – Meats, fish, shellfish, eggs, dairy products, beans, and legumes all contain galactose. 


Sucrose – Fruits and vegetables are the foods that have the highest quantities of sucrose. Additionally, sugar from cane and beets also contain sucrose. Sucrose is not a simple sugar like fructose. But sucrose and fructose often accompany one another. 

Maltose – Grains like wheat, barley, cereals, and contain maltose. Because of the growing concern about high-fructose corn syrups, many companies are beginning to use maltose to sweeten food products.

Lactose – Found in milk and dairy products, lactose is also in some sweetened breads, instant soups, and dressings. 

Trehalose – Mushrooms, lobster, shrimp, and seaweed all contain trehalose. A complex carbohydrate, most flying insects use trehalose to power their flight. 


Raffinose – Beans, cabbage, broccoli, and asparagus as well as brussel sprouts and grains, according to the International Foundation for Gastrointestinal Disorders, all contain this highly-complex carbohydrate.

Stachyose – Red, white, black, and green beans and mother’s milk contain stachyose. 

Verbascose – Peas, black-eyed peas, and cocoa beans contain substantial amounts of verbascose. 

Inulin – Bananas, wheat, a variety of roots, asparagus, and broccoli all contain large quantities of inulin. 


Starch – Corn, peas, potatoes, bread, and lima beans are the starchiest of foods, starch being the more energy-dense of all carbohydrates. 

Non-starch polysaccharides – Brans, cereals, and green and root vegetables all contain this healthy carbohydrate.

Healthiest Foods, USDA 5 Food Groups, Plus Oils

healthiest foods

The healthiest foods, obviously, are foods that aren’t unhealthy.

So, for a list of the healthiest foods, it’s necessary to eliminate foods that are unhealthy.

The following is a short list of the unhealthiest foods.

  • C.R.A.P. Foods: Carbonated drinks, refined sugar, artificial flavorings and alcohol, processed foods, – with very few exceptions, aren’t healthy.
  • Enriched flour products: White bread, “enriched” pasta, cake, doughnuts, pie crust, cake snacks, brownies, pretzels, crackers, cookies, etc. – rarely provide nutritional value.
  • Foods with excessive levels of saturated fat: Your body requires saturated fat. But too much can cause cholesterol problems if you don’t have a well-balanced diet or you live a sedentary lifestyle.

Remove C.R.A.P. Foods, enriched flour products, and foods that are excessively high in saturated fat and you can then begin constructing a diet of the healthiest foods.


Healthy Foods Fruits

Maintain a healthy weight by eating lots of fruit, lots and lots of fruit!

Nutrition and physical activity are the keys to both losing weight and maintaining the weight, figure, and look you want. Professional medical advice – from a doctor – should be taken whenever possible when attempting to lose weight. 

However, almost all health professionals and doctors agree that fruits can lower blood pressure, blood sugar levels, minimize the risk of coronary heart disease, and remove the blood plaques that can lead to cardiovascular disease. 

What makes fruits so critical to your diet are the vitamins minerals. Fruit acids may reduce your risk of dozens of diseases. And, while many fruits also contain a lot of sugar, almost none leads to high blood pressure or weight gain.

Below is a list of some of the healthiest fruits!

  • mango 
  • avocado 
  • pineapple

Healthy Foods Vegetables

The healthiest vegetables are low-carb vegetables that are high-fiber vegetables. They can prevent everything from heart disease and high blood cholesterol to poor eyesight and bad teeth. 

But, even any of the high-carb vegetables can keep your blood sugar levels down and may reduce chronic disease. In other words, many of the high-carb/high starch vegetables – like potatoes and sweet potatoes – can keep you in good health. 

Your daily requirement of a given vegetable depends on the recommended daily amount of the nutrients within that vegetable. Nutrition delivered right has tremendous health benefits. Vegetables are one of the delivery systems of human nutrition.

There are three primary types of vegetables: green vegetables, cruciferous vegetables (flower vegetables), and root vegetables. 

Green Vegetables

Leafy green vegetables, a.k.a., “dark green leafy vegetables,” or “dark leafy greens,” are widely thought of as the healthiest vegetables because they are high in vitamins and minerals and low in starchy carbohydrates.  

Green vegetables contain high quantities of vitamins A, C, E, K, and B-vitamins. 

The leafy greens include:

  1. microgreens
  2. spinach 
  3. kale

Cruciferous Vegetables (Flower Vegetables) 

Cruciferous vegetable intake, according to the National Cancer Institute, is something scientists are studying as a preventative measure for a wide variety of cancers

According to the same, “Cruciferous vegetables are rich in nutrients, including several carotenoids (beta-carotene, lutein, zeaxanthin); vitamins C, E, and K; folate; and minerals. They also are a good fiber source.”

Cruciferous vegetables may also lower your weight, increase your energy, help your cognition and mood, and improve the condition of your hair, skin, and eyes.

Meats (Beef, Eggs, Poultry, Fish/Seafood, Pork, Turkey, Mutton/Lamb, Venison, etc.)

Healthy Foods Meats

Meats contain more significant sums of amino acids (proteins) per gram than any other food source. And it’s not close.

However, there are some concerns about eating meat. For example, there are claims that pork can raise your cholesterol. Fatty beef might as well, and so too might some seafood. Large fish may contain mercury. You should consult your doctor about some of the risks associated with eating large quantities of meat.

However, the benefits associated with eating meat are undeniable. Meats are dense with amino acids, minerals, and vitamins. A non-meat diet requires eating large sums of fruits, vegetables, and grains – and a strict diet of supplements – to meet the recommended daily amount of many vitamins, minerals, and amino acids that only meats provide in quantity.

The following is a list of meats:

  1. Beef 
  2. Turkey
  3. Fish
