World War II began on September 1, 1939, when Germany invaded Poland. This aggressive act prompted Britain and France to declare war on Germany on September 3, marking the official start of the conflict. The war would go on to involve many nations across the globe and last until 1945, resulting in significant loss of life and widespread destruction. The causes of World War II were complex, rooted in the aftermath of World War I, economic instability, and the rise of totalitarian regimes. The conflict ultimately reshaped international relations and led to the establishment of the United Nations in an effort to prevent future wars.

People with celiac disease must strictly avoid gluten, a protein found in wheat, barley, and rye. This means they should steer clear of foods made from these grains, including:

1. Bread and baked goods: Most traditional breads, pastries, cakes, and cookies contain wheat flour.
2. Pasta: Regular pasta is typically made from wheat; gluten-free alternatives are available.
3. Cereals: Many breakfast cereals contain wheat or barley; look for gluten-free options.
4. Beer and malt beverages: These are usually made from barley and should be avoided.
5. Processed foods: Many packaged foods, sauces, and dressings may contain hidden gluten as thickeners or flavorings.
6. Certain grains: Avoid bulgur, couscous, and semolina, which are derived from wheat.

Always check labels for gluten-free certifications and be cautious of cross-contamination in shared kitchens. Whole foods like fruits, vegetables, meat, and gluten-free grains (like rice, quinoa, and corn) are safe choices.
