Death in middle life is usually due to the giving out of various vital
parts of the body when subjected to strain. Nervous collapse, high blood
pressure, hardening of the arteries, apoplexy, heart failure and kidney disease
are some of the types of functional diseases that are likely to set in at this
time.
To meet this period successfully, certain precautions need to be
observed.
1) Cut down on the amount of food eaten sufficiently to combat the
tendency to put on weight.
2) Be very moderate in the use of meats, salts and condiments; take
plenty of water.
3) Get plenty of fresh air and exercise, but avoid strenuous exertions
which overfatigue and place undue strain on the heart.
4) Take more recreation and rest.
5) Cultivate mental hygiene; avoid nervous strain.
Although the same nutritive essentials—fuel, protein, mineral salts and
vitamins—are required to nourish the body from the cradle to the grave, it
should be emphasized that the amounts needed are less in the latter part of
life, especially after seventy, than in the more active adult years.
There is no further need of tissue-building materials for growth, and
the amount of these substances for tissue maintenance or repair is at a
minimum. For this reason, the protein requirement in old age is reduced, while
at the same time an excess of protein is more difficult for the body to handle
than ever before.
The calorie requirement is also materially reduced for two reasons:
1) Less energy is used in muscular activity
2) Basal metabolism is lowered
It is far easier and wiser to cut down moderately on one’s fuel intake
and take more exercise when the tendency to put on weight first manifests
itself, than to try to take off excess weight by radical dieting or excessive
exercising later on. This advice should not be taken to support excessive
reduction in the amount of fuel foods with the desire of attaining underweight,
which is fully as undesirable as overweight.
Beyond a slight reduction in the amount of fuel foods and some care to
keep down the consumption of meats and other protein-rich foods, no special
modification of the diet is needed during this period.
What has been recommended as the best diet for maintaining the body in
health and vigor during younger years continues to be “optimum diet” in later
years—namely, a diet the basis of which is milk, cereal products, fruits and
vegetables, with moderate amounts of protein foods, fats and sugar. The
importance of milk, whole grains, eggs and green vegetables as protective foods
still holds good.
