Health benefits and concerns
Asthma
Vitamin C, present in fruits and
vegetables, is a powerful antioxidant and
anti-inflammatory. This anti-inflammatory activity may influence the development of asthma
symptoms. A large preliminary study has shown that young children with asthma experience
significantly less wheezing if they eat a diet high in fruits rich in vitamin C.
Bruising
Many Americans eat insufficient amounts of foods containing vitamin C; the disease caused
by vitamin C deficiency, scurvy, causes easy bruising. While very few people actually have
scurvy, even minor deficiencies of vitamin C can increase the incidence of bruising. People
who experience easy bruising may want to try eating more fruits and vegetables—common
dietary sources of vitamin C.
Capillary
fragility
Eating plenty of flavonoid- and vitamin C-rich fruits
and vegetables helps to support the structure of capillaries.
Cataracts
Some, but not all, studies have reported that eating more foods rich in beta-carotene or vitamin A
was associated with a lower risk of cataracts. Synthetic beta-carotene supplementation has not
been found to reduce the risk of cataract formation. It remains unclear whether natural
beta-carotene from food or supplements would protect the eye or whether beta-carotene in food
is merely a marker for other protective factors in fruits and vegetables high in
beta-carotene.
High
homocysteine
A controlled trial showed that eating a diet high in fruits and vegetables containing folic acid, beta-carotene, and vitamin C effectively lowered
homocysteine levels. Healthy people were assigned to either a diet containing a pound of
fruits and vegetables per day, or to a diet containing 3 1/2 ounces (99g) of fruits and vegetables
per day. After four weeks, those eating the higher amount of fruits and vegetables had an 11
percent lower homocysteine level compared to those eating the lower amount of fruits and
vegetables.
Multiple sclerosis
(MS)
In one survey, researchers gathered information from nearly 400 individuals (half with MS)
over three years. They found that consumption of vegetable protein, fruit juice, and foods rich in vitamin C, thiamine, riboflavin, calcium, and potassium
correlated with a decreased MS risk.
Pregnancy
Pregnant women should consume 1,500mg of calcium per day. Food sources of calcium include
milk products, dark green leafy vegetables, tofu,
sardines (canned with edible bones), salmon (canned
with edible bones), peas, and beans.
Stroke
Diets high in fruit and/or vegetables are associated with a reduced risk of stroke,
according to most studies. In a large preliminary study, cruciferous and green leafy
vegetables, conferred the highest degree of protection. Because it is not clear which
components of fruits and vegetables are most responsible for the protective effect against
stroke, people wishing to reduce their risk of stroke should rely primarily on eating more
fruits and vegetables themselves rather than taking supplements.
