Nutritional Fallacies - as we age

An article from my Bicycling mag on nutrition indicates we should be changing the way we eat as
as we get older.
fallacy 1: you can eat  the same at age 40 as age 20
As we age, we lose muscle and gain fat. Cycling and strength training help stem the loss. Because of age-related  kidney change, our blood becomes more acidic and we excrete nitrogen faster than we take it in. Nitrogen is an essential component of muscle protein.
Preserve muscle mass by increasing the alkalinity of your blood to neutralize the acidity ... take Acid Zapper supplement and/or enhance alkaline by eating more fruits and veggies. All other foods have an acid increasing effect. If you don't get most of your carbs from fruits and veggies, you are losing muscle mass and calcium from your bones. 
  
fallacy 2: all fat makes you fat
For years the american gov't preached low-fat carb-heavy diets ... and americans got heavier. It appears healthy unsaturated fats are essential for firing up fat-burning metabolism. In fact, starchy foods turn into stored fat more quickly. Fat is slower to digest than carbs which helps you stay hunger-free longer.
As our bodies become more conditioned (cycling, golfing, jogging, etc), fat will help you go longer and burn more calories. However, it is important to choose healthy fats such as almonds, avocado, olive oil and olives.
