Choice A rationale:

Consuming a diet high in red meat and low in fruits and vegetables is not an advisable preventive measure for uterine fibroids.

In fact, a diet rich in fruits, vegetables, and other sources of dietary fiber has been associated with a reduced risk of developing uterine fibroids.

Reducing red meat intake and increasing the consumption of plant-based foods can have a protective effect against fibroids.

Choice B rationale:

Avoiding pregnancy is not a recommended preventive measure for uterine fibroids.

In fact, some studies have suggested that the risk of developing fibroids may be slightly reduced in women who have had multiple pregnancies.

However, it's important to note that this effect is not strong enough to use pregnancy avoidance as a preventive strategy.

Choice C rationale:

Maintaining a healthy weight through regular exercise and a balanced diet is a prudent preventive measure for uterine fibroids.

Obesity and excess body weight have been associated with an increased risk of fibroids.

Regular physical activity and a balanced diet can help regulate hormone levels, including estrogen, and reduce the risk of hormonal imbalances that contribute to fibroid development.

Choice D rationale:

Increasing estrogen and progesterone levels through hormone therapy is not a recommended preventive measure for uterine fibroids.

As mentioned earlier, an excess of these hormones can actually promote the growth of fibroids.

Therefore, hormone therapy with estrogen and progesterone is generally contraindicated in women with fibroids.
