A zinc deficient diet can lead to a range of health consequences because zinc is an essential trace element that plays a crucial role in many bodily functions. Here are some of the potential consequences of zinc deficiency: 1. **Impaired Immune Function**: Zinc is vital for the proper functioning of the immune system. A deficiency can weaken the immune response, making an individual more susceptible to infections and illnesses. 2. **Delayed Wound Healing**: Zinc plays a role in maintaining skin integrity and structure. Without adequate zinc, wound healing can be slower, and the risk of infection can increase. 3. **Growth Retardation**: In children, zinc deficiency can result in stunted growth and delayed sexual maturation because zinc is essential for growth and development. 4. **Hair Loss**: Zinc is important for cell growth, and a deficiency can cause hair loss or lead to conditions like alopecia. 5. **Skin Lesions**: Skin problems such as rashes, acne, and eczema can be exacerbated by a lack of zinc. 6. **Loss of Appetite**: Zinc deficiency can lead to a decrease in appetite, which can further exacerbate nutritional deficiencies. 7. **Taste and Smell Dysfunction**: Zinc is important for the proper functioning of taste and smell receptors. Deficiency can lead to a diminished sense of taste and smell. 8. **Diarrhea**: Chronic zinc deficiency can contribute to persistent diarrhea, especially in children, which can also lead to malnutrition. 9. **Cognitive Dysfunction**: Zinc is important for brain health and cognitive function. Deficiency can impair cognitive development in children and contribute to cognitive decline in adults. 10. **Reproductive Issues**: Zinc plays a role in fertility and reproductive health. In men, zinc deficiency can lead to hypogonadism and reduced testosterone levels, while in women, it can affect menstrual health and pregnancy outcomes. 11. **Eye Health**: Zinc is present in high concentrations in the eye, and deficiency can lead to vision problems, including night blindness. 12. **Behavioral Issues**: In children, zinc deficiency has been linked to attention deficit disorders, hyperactivity, and irritability. It's important to note that the severity of these consequences can vary depending on the level of deficiency and the duration of inadequate zinc intake. To prevent zinc deficiency, it is important to consume a balanced diet that includes zinc-rich foods such as meat, shellfish, legumes, seeds, nuts, dairy products, and whole grains. In some cases, supplementation may be necessary under the guidance of a healthcare professional.

A) Some antioxidant supplements can actually enhance oxidation.
B) The optimum dose of each antioxidant is unknown.
