Dietary Supplements vs Food - Do We Have a Winner?

What are dietary supplements?

Any food that supplements the diet and contains 'dietary ingredients', for example:

• Vitamins
• Minerals
• Amino acids
• Herbs
• Enzymes

Dietary supplements are intended to be food substitutes, they cannot match the benefits that whole foods provide.

Whole food benefits

Complex foods – contain a variety of macro- and micro-nutrients which work together to provide benefits.

Essential fibre – fibre naturally occurs in foods providing numerous benefits including digestive health, diabetes prevention and satiation (which helps with weight management).

Dietary supplements in athletes

Vitamins and minerals:

Immuno-suppression affects athletes undergoing strenuous physical activity; this compromises the immune system causing increased susceptibility to illness and infection.  Therefore, the recommended daily intake of vitamins and minerals is higher for athletes than the general population.  However, consuming a balanced diet with sufficient energy intake should account for this increased requirement and therefore healthy athletes should not need to take additional vitamins or minerals in supplement form.

Additional supplementation may be required by certain athletes:

• Athletes who are 'making weight' – those on a calorie deficit diet and therefore not consuming the quantity of food necessary to provide the required vitamins and minerals may need additional supplementation.
• Athletes with food intolerance/allergy – medical conditions may affect how the body absorbs or uses nutrients consumed and therefore supplements are required to maintain a balanced diet.

Protein:

Protein occurs naturally in foods such as meat, nuts and dairy products (milk, eggs) but it is often used as a supplement among athletes in the form of powder.  Protein is vital for preventing muscle breakdown and aiding muscle recovery and therefore intake both pre- and post-exercise is important for athletes to maintain a high performance level.

It is recommended that an individual wanting to build muscle should consume 0.7g of protein per pound of body weight per day.  For a 170lb individual this could amount to 119g of protein – the equivalent of 2 chicken breasts, 3 eggs and a 6oz steak – this not only contains a lot of other ingredients including cholesterol, fat and saturated fat, (adversely affecting body composition), but is also very expensive.  Protein is essential to aid recovery, but all athletes require a different amount of protein depending on their level of activity, intensity and goals.  Protein supplements offer a convenient, quick alternative with few added ingredients.

Furthermore, whey – the most popular protein supplement – is rapidly digested and absorbed by the body, whereas protein obtained from natural food is absorbed much more slowly.  Muscles need protein in the first 30 minutes post-workout for recovery and to prevent break down and thus whey is vital for muscle building.  As whey protein is rapidly absorbed, it will be used by the muscles quickly and therefore additional protein intake is required.  A high protein meal consisting of whole foods, 1-2 hours after exercise will provide the slow-release protein needed to fuel the muscles for hours and thus maintain lean body mass.

Future trends

Although protein is the most popular supplement in the sports industry, anti-oxidant (AOX) based supplements are predicted to grow in popularity in the coming years.  AOX are vital to protect the body from free radicals – chemicals which accumulate throughout the body.  Free radicals are produced naturally by the body through metabolism and immunity, but they are also produced via contact with cigarette smoke, radiation, pollution and endurance exercise.  An accumulation of free radicals can cause illness and infection in an individual.

Regardless of how much protein an athlete consumes, if they are constantly ill they will not be able to perform to their maximum potential and therefore they will not be able to build muscle.  AOX supplements aimed at athletes are likely to become hugely popular in the future.

10 Things I Know About Protein That You Don't

1. There's No Such Thing as Undenatured Whey Protein

Here's a fact: all whey protein sold in the United States needs to first be pasteurized. Even at the lowest temperature, that means subjecting the whey protein to a level of heat that will cause changes in some of the fractions. This doesn't mean that the protein is useless or won't give you all of the benefits you see touted in advertisements and studies. It just means that undenatured is a meaningless concept when we're talking about whey protein sold legally in the United States. So unless you're clued into the whey protein black market or some whey protein-selling crime syndicate, you're not getting undenatured anything.

  

1.5. If Your Favorite Brand Sells Bioactive Peptides, Find a New Brand

Bioactive whey peptides are protein fractions that cause a measurable biological response in the body. Maybe it's enhancing the immune system or increasing pumps (for teh gainz). Those peptides come from protein. They come from the protein you buy from that same company.

See, every pound of protein might sell for $5 at the manufacturer level, but it also might contain $10 worth of peptides in 1/10th of the weight. So they strip all of those awesome peptides out, thereby losing .50c from the protein itself, but in the process they earn double the money from the sale of the peptides they removed. You get the completely denatured protein (stripped of every biologically active peptide they could mine), and they sell you back the peptides in another product (or in the same product, claiming that they have “added peptides”).

2. Cold Filtered Whey Is Still Heated

“But my whey can't be denatured from heat, it's cold filtered,” I hear someone saying. That's nice. But cold filtered is the actual filtering process that concentrates the whey into the final percentage of protein (typically +80%). The filtering has nothing to do with the fact that most manufacturers who “cold filter” their whey are still flash pasteurizing it at the highest possible temperature beforehand. Why? Because it only takes fifteen seconds to flash pasteurize whey and it takes fifteen minutes to pasteurize it at the lowest heat levels. So you can produce more whey if you only take 1/60th of the time at this stage of processing.

3. GMO/Grass-Fed Laws Are Stricter Overseas

Oh, so your whey comes from New Zealand, and you're bragging about it being non-GMO and free range and all that good stuff? Guess what? All whey from New Zealand is going to be non-GMO and free range. Their laws are far stricter than the ones in the good ol' United States, so it's a bit redundant to talk about how great your New Zealand whey is when every gram of dairy the country produces is just as good. I lived in Auckland, New Zealand, and I've been to the dairy farms, and you're from Maine, so you're probably going to have to take my word on this one.

4. No Studies Ever Compared Grass-Fed Whey to Grain-Fed Dairy

Don't get me wrong, I believe that grass-fed dairy (and beef for that matter) is superior to grain-fed. But there are no direct studies comparing them in athletes or in an exercising population. There is tons of evidence showing grass-fed animals (and their meat products) are healthier, but none on dairy in athletes. It makes a much bigger difference with meat, where the fat content can be radically altered by diet, or even with whole fat milk. But with a good whey protein, we're talking about a gram of fat per serving. So while I still prefer grass-fed (everything), this is based more on inductive reasoning than hard and fast studies that examine these parameters in athletes.

5. A 100% Hydrolyzed Whey Protein Doesn’t Exist

I've seen studies that use thirty to forty percent hydrolyzed whey and spoken to the authors. It's inedible. The reason for this is the fact that breaking down (hydrolyzing) protein is exactly what happens during the digestive process. Protein that has been 100% broken down will not stay together in any form (think about it, what would a slab of steak look like after your stomach has digested 100% of it - now imagine it as a powder). Those “100% Whey Protein Hydrolysate” jugs you see at the local nutrition chain are actually a lot lower. The “100%” claim comes from the fact that the entire jug contains hydrolyzed whey protein (no other types of protein or whey), and that protein itself has been hydrolyzed 2% (or 5% or whatever). So it's all (100%) hydrolyzed - but only by a few percent.

6. Your Amino Acids Probably Come From Dead Kittens

Ok, I'm exaggerating - but not by much. The most popular form of amino acid production is through the chemical synthesis of keratin, which requires far fewer steps (and is therefore less costly) than other methods. Keratin is abundantly supplied in hair, nails, claws, and fur. Short of staking out every hair and nail salon in China (where most aminos are sourced), producers instead make them from animals whose pelts are not good enough to use for clothing. So maybe the pelt was damaged in the slaughter process or some other horrific industrial accident. That pelt is worthless as clothing, but can still be used to synthesize leucine (or whatever). I'd estimate 95% of manufacturers are using this process or a similar one, and I'm really good at estimating horrific, awful, stuff like this.

7. Twenty Grams of High-Quality Protein Is Usually Enough

Selling more protein makes the manufacturer more money, and having a huge protein-grams-per-serving count on the label helps them win fans in the bodybuilding community. But nearly every study that looks at a decent protein source, like egg or whey, usually concludes that the additional stimulation of myotropic (muscle building) or recovery factors isn't greatly enhanced after twenty grams.

8. Worthless Aminos Are Often Substituted for Expensive Proteins

Within the industry this is known as protein spiking. Cheap aminos like glycine are used to pad the protein content of otherwise expensive whey. So if a pound of whey comes in at $6, and a pound of glycine is a $2, maybe two to three grams of the latter are put in the former. Since it's an amino and not a whole protein, it's providing those grams at a much lower cost, and doesn't appear on the label as another protein form, thereby allowing the manufacturer to still (legally) claim “100% whey” or “100% casein.” I know of one brand that uses creatine (technically an amino) to spike their protein, which as a bonus is super-easy to flavor. Their protein is delicious. Now you know why.

  

9. Twenty Grams of Protein Usually Isn’t

Protein bars are notorious for under-dosing protein and overstating the amount on the label. This is a bit of an open secret in the industry, and although powders are better, they're still under-dosed in a lot of cases. Naturally, the yummy carbs are the exact opposite - you'll find far more in the bar than you see on the label.

9.1 Twenty Grams of Protein Usually Isn’t (Part Two)

Hydrolyzed collagen is technically protein. But it doesn't build much muscle, and it has a biological value of virtually nil. I'm talking about the stuff we've been seeing in gels and goops for the past decade (allegedly, there are some recent forms that aren't useless, however it's unlikely that your favorite brand is using them). Gels are obviously the worst offender here, but those little protein shots are pretty bad also.

10. Most Protein Comes From the Same Place(s)

If you were to walk the aisles of your local supplement retailer, you'd see dozens of different brands of protein. But if you were to see the actual manufacturers of the protein itself (the people all of those brands are buying it from), you'd see far fewer companies. There are probably ten major players in the field of powdered protein, and that's being generous. They're not just huge; they own other companies that we think are huge.

Glanbia, for example, produces a lion's share of the dairy products in Ireland. They're a billion-dollar company, they own BSN as well as Optimum Nutrition, and they do contract manufacturing for tons of other companies, both big and small (well, medium). So, when you see Brand X Casein and the store house brand and BSN and ON, all sitting next to each other, there's actually a good chance that the protein in the jugs is identical. And Glanbia is the manufacturer behind the most popular protein brand(s) in the CrossFit world, if we're keeping score at home.

Top 10 Foods to Gain Muscle Mass

What if I told you that you could gain more muscle mass with less training? Or retain more muscle mass with less training? And even gain/retain more strength with less training? The secret is nutrition.

As a personal trainer, most of my clients exhibit this behavior: they train hard, but they don’t give a heck about nutrition. So the time and effort they spend on training is wasted. Why? Because they think nutrition is complicated and they avoid the topic. I understand perfectly, because I used to be like that as well.

But we need to train smart. This means knowing how nutrition works and how to utilize it for your own fitness and strength gains. This works for anyone and everyone, be it for general fitness maintenance or muscle mass gain.

To get you started, here is my list of the top ten foods to help you gain more muscle mass and strength:

1. Lean Beef

This should be a STAPLE of your diet if you want to gain muscle mass. Why? Because it is loaded with all sorts of things conducive to muscle growth. On average, a three-ounce serving of lean beef is only 154 calories, yet it provides ten essential nutrients, including iron, zinc and B-vitamins. More importantly, it provides your body with high quality protein (not all proteins are equal), and a high level of amino acid that works with insulin to promote muscle growth. For those who are trying to lose weight, this should come as great news – a 3 ounce serving of lean beef provides roughly the same amount of protein as 1.5 cups of beans, but at half the calories.

2. Skinless Chicken

Like beef, it is an excellent source of high quality protein, which is important for muscle maintenance and repair, bone health, and weight maintenance. And of course, there are so many ways you can cook and prepare chicken. Go down to the store and you can easily find chicken meat cut into single serving sizes that can be seasoned and quickly cooked.

3. Cottage Cheese

Not many people know this, but cottage cheese constitutes relatively pure casein protein. For those who don’t know, casein protein is a slow-digesting protein, which means it is perfect for muscle maintenance. This is useful especially for guys who have no choice but to go long periods without eating. Not forgetting, cottage cheese is also an excellent source of vitamin B12, calcium, and other important nutrients. My advice: buy the nonfat/low-fat versions.

4. Eggs

Eggs contain high quality protein, nine essential amino acids, choline, the right kind of fat, and vitamin D. To sum it up, they are the most value for money. And please note, eggs are not harmful for your health, as numerous studies have already shown.

5. Whey Protein

There is a reason why whey protein supplements are the most popular supplement in the bodybuilding world: because they provide a fast and convenient source of protein at an affordable price. Bodybuilders normally use them when they wake up, right after their workout, and mixed with some of their meals. However, for those of us non-bodybuilders, simply using it right after our workouts can be very effective for muscle mass gains. Do not rely on it completely though. It’s more important to get high quality protein from whole foods, and use whey protein as a boost. There’s so much more about whey protein, if you want to find out more, click hereto read a comprehensive article I have written on how to best benefit from it.

6. Tuna and Other Fish

High in protein, low in fat, and rich in omega-3 fatty acids. The key here is omega-3 fatty acids. They are essential, not only for health reasons, but also because they improve fat loss and ensure the proper function of your body processes, such as your metabolism.

7. Oatmeal

Oatmeal is an ideal source of carbs due to both its low glycemic index (GI) value and the fact it is minimally processed. The benefits of a low GI diet are as follows:

• Better micronutrient profile and more fiber
• Increased satiety
• Decreased hunger
• Lower subsequent energy intake (second meal effect)
• Fat loss

In short, enhanced fat loss for those looking to lose weight, and a constant source of carbs for muscle preservation.

8. Whole Grains

Whole grains digest more efficiently and provide more nutrients than refined grains, and as such promote sustained energy levels and overall health. For instance, brown rice can help boost your growth hormone levels, which are critical for encouraging lean muscle growth, fat loss, and strength gains.

9. Fruits and Vegetables

Firstly, fruits and vegetables are a rich source of antioxidants, which are essential for the healthy functioning of your immune system. Secondly, they provide tons of other nutrients, such as vitamin C, vitamin E, and beta-carotene. Finally, your body requires the fiber these fruits and vegetables provide, which helps to flush out the substances your body does not need.

10. Healthy Fats

I know some of you shudder at the thought of consuming fats, but good fats are essential for muscle growth. In fact, they play an essential role in hormone production (testosterone and growth hormones) that is responsible for muscle growth and strength gains. Your metabolic rate is elevated as well, which helps you shed more fats. In addition, fats are needed for many important maintenance functions. Polyunsaturated and monounsaturated fats are the good fats. You can find them in salmon, other fishes, nuts, leafy veggies, oils such as flaxseed, avocados, and seeds. They are also all rich in omega-3 and omega-6 fatty acids.

Why All Humans Need to Eat Meat for Health

With veganism trending, many people are convincing themselves that plant-based foods can suffice when it comes to daily nutritional needs, removing all traces of meat from their diets. Unfortunately, these people may be experiencing vitamin deficiencies and suffering decreased brain volume, fatigue, and confusion.

The Myths About Eating Meat

One of the greatest and most harmful nutrition myths is that meat doesn’t belong in a healthy diet. Meat consumption is blamed for high cholesterol, high blood pressure, heart disease, and obesity. But if you want to point fingers at the culprit behind these health issues, point at sugar. Blame the overconsumption of carbohydrates like grains and potatoes that break down into sugar in the body.¹



For more than two million years we were primarily meat eaters. Only in the last 10,000 years did the human diet shift, with the cultivation of grains and legumes. But are we more suited to this diet lower in meat? In the last 10,000 years we’ve gotten smaller in stature and brain size. With a heavily grain- and sugar-based diet, we are suffering increased rates of obesity, cancer, diabetes, and osteoporosis. We’re also experiencing alarming incidence of skin problems, heart disease, and inflammation of all kinds.²

I have to politely disagree with the anti-meat argument. Our genes were developed before the agricultural revolution, when we were not only meat eaters, but enthusiastic ones at that. On top of that, the human genome has changed less than 0.02% in the last 40,000 years. Our bodies were genetically programed for optimal functioning on a diet including meat, and that programming has not changed.

There’s plenty of information circulating about why we shouldn’t eat meat. Here are some reasons why we should:

We Were Created That Way

By nature, humans are meat eaters, and our bodies are designed for it. We have incisors for tearing meat, and molars for grinding it. If we were meant to subsist on vegetables alone, our digestive system would be similar to that of the cow, with four stomachs and the ability to ferment cellulose in order to break down plant material.

The degenerative health conditions that are prevalent now weren’t around when the cavemen were living off meat, vegetables, fish, nuts, seeds, and fruits. In hunter/gatherer societies, 45-65% of energy requirements were derived from animal sources, and heart disease, obesity and type 2 diabetes - the diseases that plague society today - were not a problem.³ With the introduction of grains and processed foods, these diseases reared their ugly heads at alarming rates.⁴

Stable Blood Sugar

Meat helps keep blood sugar levels stable due to its fat and high protein content. Steady blood sugar is critical in preventing type 2 diabetes, as well as other chronic diseases. It also helps keep energy levels steady and creates a feeling of satiety between meals, reducing cravings for unhealthy foods.⁵ With stable blood sugar, you’re less likely to drool for fattening snacks and sweets between meals. Battle sugar cravings by eating more meat.⁶



  

Muscle Growth  

You can work yourself to the bone trying to gain muscle or bulk up, but if you don’t nourish your body appropriately, you might as well toss your training schedule and start long distance running. You have to fuel your body with the right nutrients to achieve sufficient muscle repair and recovery to make gains.

You can take protein supplements, but the best source of protein is meat. Meat also contains vitamins and minerals that aid in muscle growth like zinc, which assists in muscle repair, and iron, which boosts energy levels and combats fatigue. Meat also contains creatine, a nitrogen-containing compound that improves protein synthesis and provides muscles with energy, encouraging muscle gain.

If meat’s positive - strike that, crucial - role in muscle growth isn’t enough, meat also helps burn fat. Meat has a high thermogenic effect because of its protein content, so that approximately thirty percent of its calories are burned off during digestion alone. Digesting carbohydrates produces only a six to eight percent increase in energy expenditure, while digesting the protein in meat typically produces a whopping 25 to 40 percent increase.⁷

Neurotransmitter Health

People who don’t eat meat are especially vulnerable to neurotransmitter imbalances because of the absence of meat protein, which provides all of the essential amino acids human bodies need. Neurotransmitters are chemical messengers that regulate many of our functions, including physical, cognitive, and mental performance, as well as our sleep cycle, weight, and emotional states. Meat protein provides all of the essential amino acids human bodies need. People who don’t eat meat are especially vulnerable to neurotransmitter imbalances, which can result in problems like depression, anxiety, and hyperactivity.

According to research conducted at the University of Graz, vegetarians are two to three times more likely than meat eaters to suffer from depression, anxiety, eating disorders, and somatoform disorders and syndromes.⁸ We rely on prescribed medication to cure some of these conditions, when the answer may be as simple as eating a juicy hamburger or tender chicken breast.

Long-Lasting Energy

Everyone has experienced that post-meal slump when caffeine is the only thing that can keep one’s head off a pillow. Simple carbs are broken down into sugar that our body burns through quickly, causing us to crash. Conversely, our bodies utilize the protein in meats for sustained, long-lasting energy. 

  

Another critical component of feeling energized is the stimulation of orexin cells in the brain. The stimulation of orexin cells is directly linked to energy expenditure and wakefulness. Scientists at the University of Cambridge discovered that amino acids stimulate orexin cells more than any other nutrients do. Thus, consuming meat protein leads to burning more calories and more energy. Reduced activity in orexin cells has been linked to both weight gain and narcolepsy.⁹

In addition, meat is one of the best sources of iron. Iron deficits put you at risk for anemia and low energy, which is why anemia is a chronic problem for vegetarians. Pair meat with vegetables boasting a low glycemic index, and you’ll be feeling like the energizer bunny all day long.

Essential Nutrients

There are many nutrients in meat that are critical to overall health. While there are many sources of protein, meat is a great source of complete protein, containing all the amino acids our bodies needs, including the ones our bodies can’t produce.

All B vitamins are found in greater concentration in meats than in plant sources, and vitamin B-12 can only be found in animal sources. The B vitamins are critical to health, especially mental health. Deficits in these vitamins can cause confusion, impaired senses, aggression, insomnia, weakness, dementia, and peripheral neuropathy.

The Bottom Line

The last reason to eat meat? It tastes pretty damn good. Steak off the grill, roasted chicken, tender pot roasts, need I say more? For most of us, a meal is not a meal without a delicious cut of meat at the center of it. We love meat, and meat loves us back with a host of critical health benefits. So be true to your human nature and to your taste buds. Don’t cut meat out of your life. It has way too much to offer.
