This is a quote from Napolean Bonaparte. It has deep implications. In the literal sense, an army of soldiers requires a lot of food to keep it going. That is why in old days, young soldiers would shack up with farmers in the countryside and eat them out of house and home.
But it means something else too. Nutrition is the first thing in health. Even a strong, energetic athlete would be weak and depleted without the proper amount of food. An Army Marches On It’s Stomach. Deep.
The most important nutrient in physical strength is Protein. The word was coined by the scientist who founded the nutrient, and it means, ‘of primary importance.’ We are made up of proteins, amino acids to be more precise, and eating a high protein diet makes you strong and muscular. This goes for both plant and animal foods.
You also need a lot of B vitamins for strength, since those are what act as catalysts in the chemical reactions in your body to produce energy. Strength isn’t just muscularity, it is energy and speed too. I think a great source of B vitamins are the leafy greens.
So you see, we are what we eat, and if we eat right, we will have the strength to do whatever we desire in our heart, whether it be fighting or healing or loving or just plain philosophizing.
