I’ve been keen on what constitutes “an excessive amount of of factor” with endurance train for a while. I first mentioned it in my put up “How A lot Train Is Too A lot?” and gave an replace on it right here. I not too long ago got here throughout an article within the peer-reviewed journal Vitamins that gave an attention-grabbing perception into the connection between endurance train and weight-reduction plan [1], particularly with regard to cardiovascular well being. They reviewed disturbing proof that those that do a number of endurance train could also be at elevated danger for coronary artery illness, and commented “surprisingly, endurance athletes might have extra superior atherosclerosis and extra myocardial harm, in contrast with sedentary people, notably as they age”.
The authors then identified that endurance athletes are likely to eat greater than their sedentary counterparts, to gasoline their exercise. However this additional gasoline just isn’t essentially wholesome, particularly if they’re consuming a typical trendy weight-reduction plan just like the Normal American Food regimen. Since many specialists imagine such a weight-reduction plan comprises extreme quantities of animal protein and saturated fats, consuming larger quantities of it might make issues worse. They then go on to argue that these exercisers can be higher off consuming a wholesome plant-based weight-reduction plan which might reduce the load of animal meals which will contribute to arterial plaque formation. It will additionally cut back one other contributor to coronary artery illness, irritation.
I found this text in a video on Dr. Michael Greger’s web site entitled “Why All Athletes Ought to Eat Plant-based Diets“. He reviewed the proof that has been beforehand offered on the advantages of plant-based diets for athletes, most famously within the documentary “The Gamechangers“. However he additionally emphasised the brand new perception offered in ref [1].
Whether or not a plant-based weight-reduction plan is critical to cut back the danger of coronary artery illness amongst getting old athletes could also be controversial. First, I at all times wince after I see “plant-based” as a substitute of “whole-food plant-based”. I notice the latter is awkwardly lengthy and it might be tempting to only say “plant-based” as an alternate, however it is a slippery slope. There are lots of unhealthy overprocessed meals which are nonetheless plant-based, similar to sweet and potato chips. Second, extra animal protein and saturated fats are usually not the one issues improper with typical trendy diets, in addition they comprise extreme quantities of sugar and different “dangerous carbs”. However I believe it’s clear that getting old athletes ought to keep away from the temptation of considering they will eat no matter they need and they’re protected by their train. Even for many who are usually not satisfied it’s essential to observe a whole-foods plant-based weight-reduction plan, it will nonetheless be a good suggestion to observe wholesome consuming suggestions, similar to Harvard’s Wholesome Consuming Plate.
Within the well-known novel As soon as A Runner, the lead character, a aggressive collegiate runner, describes his consuming by saying “if the furnace is scorching sufficient it doesn’t matter what you place in it”. I believe many athletes have this perspective, I actually leaned in that path after I was youthful. I used to be pleased I might get away with consuming just about no matter I needed so long as I exercised sufficient. However I imagine this turns into extra harmful as we age.
