I like to republish this one every so often, because little about our needs has changed since it was first written. If you have anything to add, please let me know by leaving a comment.
Please note that since I originally posted this, it has been augmented and edited a few times. Naturally, I was deeply saddened to hear about Steve Larsen's passing and would have to change the link I'd originally had for him down below, which went to his then commercial real estate venture. Now it is a remembrance page. Steve paid close attention to his performance, including nutrition, which goes to show that there really are no guarantees in life. Life is a risk and there are no more opportunities for risk after it.
Nutrition has always been a hot topic for endurance athletes. (Note my high-tech usage of the orange font to emphasize the word hot.) Over years of "refinement", I've found that it's the basics that work, and they work on a wide range (free range?) of athletes...I shall edit this and re-post it over time but the fundamentals hold steady. Namely, think before you eat.
Other key points:
1) Eat a big variety of REAL foods only, ala Caveman style. "Real" foods are foods that have recently been ALIVE (or are indeed alive) and were unaltered/unprocessed after death. Human evolution has not kept pace with advances in agriculture and food processing, resulting in a virtual plague of health problems for modern man; you needn't search far to see evidence of this. The best foods have no "nutrition" label or ingredient list; they weren't "created" and they aren't labeled as "health foods". Again---and this bears repeating---they are ALIVE or were just recently. Food = energy, if it's the kind that grows. It is your ONLY source of life-sustaining energy and your body's ONLY building block. Eating food that is (or was recently) alive will a-live-n you! Anything with a long shelf-life is suspect at best and not all calories are created (or affect you) equally. Limit packaged (or canned or bottled or container-ed) crap and foods with more than one or two ingredients. All you anorexics please note that it's best to eat foods with at least one ingredient, however. "Real" foods are foods that haven't been processed or require processing before hitting your stomach: veggies, nuts, seeds, eggs, meats, seafood, fruits (minimally), nut butters, good oils, etc. Primeval shit. Even the wise, old Jack Lalanne (one of my neighbors here in California, oddly enough) once said, "If man made it, don't eat it." (Keep in mind some processed foods are alright: V8 and veggie juices, extra virgin olive oil, apple cider vinegar, extra virgin coconut oil, etc.)
2) As an athlete you should know the glycemic response of various foods and when the best time to eat them is---in a nutshell: fat and protein before longer, easier (predominantly aerobic) workouts, some carbs during workouts, and carbs and small amounts of protein afterward. Generally, if it's a fat-burning, aerobic workout consider ingesting more fat. If it's a sugar-burning, anaerobic workout consider taking in a higher percentage of carbohydrates. The timing of what you eat is important! (By the way, I hate the truncated word "carb", just as I do "cardio"...my apologies for its use but time is of the essence.)
The sad but avoidable truth in the western world is that excessive consumption of high-glycemic carbs is the primary culprit in nutritionally caused health problems. High-glycemic carbohydrates are those that raise blood sugar too rapidly. They include rice, bread, candy, potatoes, sweets, sodas, and most processed carbohydrates. Processing can include bleaching, baking, grinding, and refining, and this processing greatly increases a carbohydrate's glycemic index, the measure of their tendency to elevate blood sugar.
3) Avoid "bad" stuff...caffeine and other stimulants (end that chemical romance and get your energy from nutrients, not stimulants!), drugs/medications, high-dose sugars, refined sugars, grains (there's no such thing as an unprocessed grain, even "whole" ones), alcohol (some red wine is good, actually, and can aid in digestion and sleep), bad fats (trans, hydrogenated and partially hydrogenated, fractionated, and unnaturally saturated. By the way, what is partially hydrogenated? It's either hydrogenated or it's not! She was partially pregnant!) and foods with long ingredient lists; your body has to filter through all that crap and it takes work. And be wary of dairy. Know your body's allergens, as well. It's surprising to me how so few professional athletes know theirs; they go on to waste half a career wondering why their body's don't comply with their wishes. The bottom line: know your body and know what affects it and how it affects it.
To me, the biggest killers in the American diet are those quasi-edible "foods": high-fructose corn syrup, partially-hydrogenated oils, and bleached, enriched flours...and an obvious overabundance of them all. We're the most overfed undernourished country in the world! My guess is that diabetes will be our number one killer within twenty years or so, tied with heart disease, cancer and all those other avertable ailments. Of course, diabetes is closely related to obesity, which is in no short supply here. They say we're in an obesity epidemic, as though it were polio. ("How'd ya git through the obesity epidemic granddad?" "Oh, it was rough Johnny...there was pork chops and potato chips everywhere!" Give me a frickin' break!)
4) Know that a good diet can help you reach your goals, contrary to what others may lead you to believe. Nutrition matters! But just as it is (or should be) with your training, you need to think of it as a long-term approach. Nutritional choices affect us immediately and again over the long-term. It's the time between the two that leaves us wondering. And here's my take on it: if it affects us both immediately (i.e., good food = good recovery, etc) and then again down the road (i.e., long-term health benefits), then it must help our cause in the time between. There are few athletic studies showing the long-term importance of good nutrition...another reason not to fully rely on "science," but on common sense (whether it's common enough or not).
5) Graze! Eat smaller amounts more often and stop eating before reaching satiety. This helps stabilize your blood sugar levels and is easier on your digestive system and, to be sure, humans waste a lot of energy in digesting a big meal. Compared to the caveman, we're quite inefficient at digestion and temperature regulation, two things we can easily control. If you're hungry all the time you're probably not eating enough. But it's important to realize the difference between hunger and appetite...they are not the same thing. Hunger is a need and appetite is a want. You don't need more sugar---you want it. You don't need more caffeine---you want it. You need to eat. You don't need to want to eat. In a land that gives you such opportunity, you make your own choices.
5.5) Chew your food! Proper digestion begins in that big, ugly mouth of yours, thanks not just because of enzymes, but also due to CHEWING. Slow down, breathe, chew, repeat as necessary, then swallow. Downing your food whole is a good way to not only cause your body energy but ensure that you get less of it from what you're ingesting. I'm often quite lazy in this sense so I use a blender, pinch my nose, and down whatever I'm "drinking"...though I still let my toothy orifice do its job before swallowing.
6) Learn a routine you like and one that will benefit you. A nutritional routine is fine if said routine includes a huge variety of healthy foods. (Remember: there is no optimal diet, only yours. Our ancestors and our upbringing all made us differently and thus different.) I suggest eating the bulk of your daily calories by 1pm and limiting late night calories, particularly if you have a propensity to keep weight on. That said, consider taking in a small amount of protein before bedtime, as this is when your body goes into a muscle-repairing anabolic state (this assumes you trained and did some damage to them beforehand, as smart training requires). The protein will be put to good use!
7) Increase fiber intake but from salubrious sources, not just government-pushed grains, which contain far less nutrient content than unprocessed leafy foods do. Veggies are the key here. Avoid eating too much fiber with nutrient dense foods as fiber limits absorption. Also, be wary of taking in too much fiber during race week: the last thing you want on race morning is your pre-race meal knocking on the door to the outside world a few minutes before the starting gun fires. Those porta-potties are busy enough, and they stink something fierce.
8) Aim for close to 50-30-20 percentage (CHO-Fat-Pro) on most training days, but experiment with this. Eating too little fat has a tendency to increase hunger (and therefore eating) and affects glycemic response detrimentally. (Regarding the glycemic response of food, see Number Two from above.) My personal fat intake has always been closer to 65-75% of my overall caloric input, I kid not. Fat, no doubt, is my favorite food group! I've repeatedly been "assured" that this is unhealthy by the so-called "experts" and yet I've eaten this way throughout my 20-plus-year athletic career and still have super low LDL (the "bad" cholesterol) levels and a healthy blood profile, and I rarely succumb to illness (mental illness notwithstanding). Granted, all the fat I eat comes from salubrious sources: fish/fish oils, nuts, seeds, avocados, olives, coconut oil (what I consider an absolute magic food for the athlete, with it's medium-chain triglycerides), etc. These fats are only evil if you (decide to) store them (in you).
9) Drink lots of water, preferably distilled with an added pinch of Celtic sea salt, between meals. If not distilled, go for bottled spring water. If not bottled spring water, go for the filtered municipal stuff. Chlorine is a killer and it's precisely why it is used: to kill micro-organisms. In the grand scheme of things, you too are a micro-organism. It's nice to know we swim in and ingest such stuff. You should need to heed the call of nature (#1) at least 5-6 times daily. Clear, not yellow! From an environmental standpoint the best thing you can do is shun plastic (which probably isn't all that good for your health anyhow) and put a filter on your tap at home. All those plastic bottles are burying our landscape and filling our oceans.
10) A food-derived multi-vitamin, some calcium and some fish-oil capsules each day may be wise insurance. Again, get your supplements from whole food sources and reliable companies (ala Standard Process). If your daily protein intake is limited (i.e., you're a vegetarian), you might consider some supplementary BCAAs as well: branched chain amino acids. Keep in mind that supplementation is not an excuse for a shitty diet or poor nutritional practices. Throwing vitamins and minerals into a body that is over-acidic, out of balance, and in dire need of antioxidants and raw enzymes (because of a poor diet) can never address the cause of the symptoms, nor does it ensure that you'll be able to process and absorb the supplements in the first place. Finally, beware that there is very little evidence as for the proposed performance and/or health benefits of the vast majority of supplements and ergogenics. The only thing proven to enhance performance is consistent hard training (loading the bar), so quit reading and get going.
11) A quick story: Years ago, when I used to reside at the Olympic Training Center in Colorado Springs, my roommate, Steve Larsen, and I started a game called Help or Hurt. Whatever we did, whatever we ate, we were to first ask ourselves: would this help our cause or would it hurt it? Ask yourself the same when you ingest something; it can't hurt.
The basis of an optimal dietary routine for the endurance athlete…
**Grazing
**Timing (knowing the glycemic response of food) (eating the bulk of your calories EARLY in the day)
**Veggies (all). A "salad a day" is a golden rule of mine.
**pH balancing (aim to eat more alkalizing foods and fewer acidic ones: veggies, basically)
**Fruits (during training or with nut butters to slow absorption - glycemic response)
**Nuts/seeds/nut butters (raw nuts and seeds are best) (I mix roasted, salted ones with raw ones, to make them more tolerable). Chia seeds, sunflower seeds, almonds, cashews, macadamia nuts, etc, etc, etc.
**Avocados (a magic food as far as I'm concerned!)
**Olive Oil (green-ish, extra virgin, cold-pressed)
**Food with fiber: veggies, apples, blender-ed food!
**Meat: lean cuts, variety (free range turkey; chicken; ocean fish; some red meat, though NOT the ground crap) (Avoid bigger fish and bottom feeders; they contain more toxins and pollutants)
**Eggs (spend the extra money and get the good ones)
**Legumes, if your gut can handle them. I no longer eat them, as most need processing to be deemed edible before reaching your mouth.
**Alcohol: red wine, small amount with red meat and vitamin C (kiwi fruit and or a small salad) is a great evening meal for the endurance athlete once or twice a week
**High anti-oxidant foods (garlic, blueberries, grapefruit, goji berries, kale, etc)
**Lots and lots of distilled water (but ideally only between meals as to not dilute digestive enzymes), with a pinch of sea salt.
Good snacks include…
Cucumbers with hummus or pesto
Bananas smothered with nut butters
Apples with or without a nut butter
Applesauce (the unsweetened stuff)
Guacamole! (homemade)
Canned pumpkin sprinkled with Stevia
Low glycemic fruits
Nuts, seeds
Jerky (without a long list of ingredients) (take some water in with any dried food)
A note about sodium: According to my buddy PZ Pearce, past Medical Director at Ironman Hawaii and tons of other Ironmans worldwide, as well as being the keynote speaker at our Solvang Triathlon Camps here in sunny Solvang, a surprising number of endurance athletes run low on sodium. Perhaps this is because of over-hydration or all the bad press it receives in the mainstream media, we know not. Add some sea salt to your meals or drink the occasional V8 or tomato juice to help increase your sodium intake if you think you might need to. See your doctor to know for sure.
Some of my favorite nutrition links are Modern Forager, Balancing Alkaline/Acidic Foods and Mark's Daily Apple by an old friend (and I mean OLD) named Mark Sisson, ex director of the US Triathlon Federation. Also, search Gordo's website for tons of good nutrition (and training and finance and life and shirtless posing) information. He's another friend, though not so old.
Finally, and though this has nothing to do with nutrition, I advise anyone and everyone who is serious about their triathloning to check out Alan Couzen's excellent write-up on The Ultimate Success Formula for Triathletes. He absolutely hits the nail on the head and drives it home HERE. Alan's is, by and large, one of the best triathlon-related blogs in existence.
