Diet And Nutrition Advanced - Qp3

When we diet by cutting calories or skipping meals, our body goes into a state of deprivation, causing a decrease in blood sugar levels. This drop in blood sugar triggers hunger signals in the brain, leading to cravings for food. Therefore, it is true that when we diet in this manner, we often experience cravings for food.

Antioxidants are compounds that help protect cells from damage caused by free radicals. Free radicals are unstable molecules that can cause oxidative stress and damage to cells and tissues in the body. Antioxidants work by neutralizing these free radicals, reducing their harmful effects and promoting overall health and well-being. Therefore, the statement that antioxidants block or mop up free radicals and reduce damage to cells and tissues in the body is true.

The correct answer is bloating and flatulence, abdominal cramps, and mild diarrhea. These symptoms are commonly associated with both protozoa and worm infections. Bloating and flatulence occur due to the release of gas in the digestive system caused by the presence of parasites. Abdominal cramps are a result of the parasites irritating the intestinal lining. Mild diarrhea can occur as a result of inflammation and disruption of the normal digestive process caused by the parasites. Weight gain is not typically associated with these infections, so it is not included in the correct answer.

The statement suggests that fortifying modern food with vitamins, minerals, and phytochemicals is seen as a positive trend. This implies that adding these nutrients to food is beneficial and can contribute to a healthier diet.

The correct answer is 95-98. This range indicates that a significant majority of people who lose weight by reducing calories end up regaining the weight lost and even putting on additional weight.

The statement suggests that while refined sugar may have a high glycemic index, it is not the primary cause of obesity and chronic disease in society. This implies that there are other factors contributing to these health issues.

The statement is false because human intestinal parasites can be either two-celled parasites known as protozoa or intestinal worms. The statement incorrectly suggests that all human intestinal parasites are either protozoa or worms that inhabit the small or large intestine, when in fact there are other types of parasites as well.

The statement in the question is not accurate. While photochemicals are compounds found in plants that can have various health benefits, it is incorrect to state that they prevent cancer, protect against aging and heart disease, and boost the immune system. While some photochemicals may have antioxidant properties and contribute to overall health, their effects on specific diseases and conditions vary and are still being studied. Therefore, the given answer, False, is correct.
