Importance of well balance diet
All food contains all of the nutrients we need to be healthy, it is necessary to eat various foods in sufficient amounts. A good diet will include many different foods, and sufficient in quantity and quality to meet an individual’s need for food energy and other micro nutrients.
TURNIPS
Typical serving size:
½ cup, cooked (2
75 oz or 78 g)
HOW THEY HARM
Bloating and flatulence
Thyroid function
WHAT THEY HEAL
Cancer
High cholesterol
Vision
Bones
Reproduction
Immune system
Turnips (including the yellow rutabagas) are economical, healthful, and easy to prepare and
cultivate (even in soil of poor quality), and full of vitamin C and some essential amino acids
One cup
of boiled turnips yields only 35 calories while providing 18 mg of vitamin C, 35 mg of calcium, and
210 mg of potassium
They also contain lysine, an amino acid that may help to prevent and manage
cold sores
QUICK TIP:
Go beyond boiling
Most people serve boiled turnips, but they can also be baked, braised, or steamed
The roots and
green tops make a tasty addition to salads, stews, and soups
The turnip tops, or greens, which many cooks discard, are even more nutritious than the roots
themselves
One cup of boiled greens provides 40 mg of vitamin C, about 200 mg of calcium, and
nearly 300 mg of potassium
In addition, unlike the roots, the greens are an excellent source of beta-
carotene, an important antioxidant nutrient that the body converts to vitamin A
The same cup of
boiled greens yields nearly 7,500 IU of vitamin A and 5 g of fiber
Health Benefits
Protects against some cancers
As a member of the cruciferous family, which includes cabbage,
broccoli, and radishes, turnips contain sulfurous compounds that may protect against certain forms of
cancer
Lowers cholesterol
Both the tops and roots of turnips are a useful source of fiber, including
soluble dietary fibers that help soak up LDL (“bad”) cholesterol
Promotes total body health
One cup of cooked turnip greens contains generous amounts of beta-
carotene which the body converts to vitamin A
This antioxidant plays a role in healthy vision, bone
growth, reproduction, cell functions, and a healthy immune system
Health Risks
May cause flatulence
Like other cruciferous vegetables, turnips can cause bloating and gas
Thyroid function
Turnips contain two goitrogenic substances, progoitrin and gluconasturtin,
which can interfere with the thyroid gland’s ability to make its hormones
These compounds do not
pose a risk for healthy people who eat moderate amounts of turnips, but anyone with hypothyroidism
should cook this vegetable since cooking appears to deactivate goitrogens
Allergies
Puree cooked turnip roots and serve with steamed turnip greens
Roast chunks with sweet potatoes and onions
Add baby white turnips to a crudité platter
Small turnips of about 2 in in diameter may only need to be well scrubbed, not peeled, before cooking
Buying Tip
s
Turnips should be firm and feel heavy for their size, with smooth skin that has no mushy or sunken
brown spots
Turnips with the tops attached should be brightly colored and fresh, with no signs of wilting or yellowing
Don’t buy turnips larger than 3 in (7
6 cm) in diameter
They’ll likely have a more woody taste
Storing Tip
Refrigerate turnips in a plastic bag in the crisper for up to 2 weeks
