Titanium dioxide is indeed a key ingredient in many sunscreens as it's effective in blocking UVB and short-wave UVA rays. However, it may not be enough for comprehensive sun protection on its own. It should be combined with other ingredients like zinc oxide which can block the entire spectrum of UVA and UVB rays for broader coverage. Additionally, sun protection should also include protective clothing, hats, sunglasses, and seeking shade during peak sun exposure times. Always remember, no sunscreen can block 100% of the sun's harmful rays, so frequently reapplication and other protective measures are necessary.

Excessive fiber intake, often surpassing 70 grams per day, can lead to various discomforts and health issues. Common symptoms include bloating, gas, and abdominal pain due to the body's difficulty in digesting large amounts of fiber. Additionally, it can cause constipation or diarrhea, depending on how the fiber affects bowel movements and water absorption in the colon. In severe cases, it may lead to intestinal blockage, especially if fluid intake is not increased to match the high fiber intake. Over time, excessive fiber can also interfere with the absorption of essential nutrients such as iron, zinc, magnesium, and calcium, possibly leading to nutritional deficiencies. Moderating fiber intake and ensuring a balanced diet, while staying hydrated, can help mitigate these symptoms.
