Preliminary research suggests eating vegetables and fruits may be our best dietary fountain of youth. As we age, we experience a gradual muscle wasting called sarcopenia. If you look at body fat percentages for a 20 yr old versus a 65 year old, you see vastly more muscle in the younger and more body fat in the older person.
A 2008 Tufts University study suggests this muscle wasting could be a result of our high-protein, wheat, corn and rice diets. These foods create an acidic residual in our bodies. To maintain a neutral pH, our bodies may sacrifice muscle. To prevent this, we should eat more potassium-rich foods. Try these potassium powerhouses to keep your muscle tone. Contrary to common sense, acidic foods such as tomatoes still create a non-acidic/alkaline residual:
Tomoto sauce
Beet greens
Dates
Grapefruit
Lima beans
Plantains
Spinach
Plums
Peas
Prunes
All fruits and vegetables are a good bet!
