That depends on their ingredients! They can certainly be healthy; if you are baking them yourself, don't add too much sugar and try using brown sugar or honey instead.
This depends how much tuna/sweetcorn you put in the sandwich and what bread you use (and how much bread there is).
Yes if you eat too many, like poppy seed muffins. It is an opiate.
Because the muffins have been eaten by the silly orangatangs. Then the rangas got sick from too many muffins and spewed on the huge elephants. Go muffins. The rangas are the best.
Food that has too much roughage (like Bran) that is hard to digest and pass out in bowel movements
Stale corn muffins will be dry and hard, and unpleasant to eat. OTOH, if stored with too much moisture, muffins may spoil, growing mold. These would have a sticky, slimy feel on the outside, and smell nasty.
Yes, chickens can eat bran flakes in moderation as an occasional treat. However, it is important to ensure that the bulk of their diet comes from a balanced feed designed for poultry to meet their nutritional requirements. Too many bran flakes can lead to nutritional imbalances.
Bran mashes were fed long ago in the belief that they worked on horses as a laxative in the same way they work on people. However modern science has proven the amount of fiber in a bran mash is not high enough to work as a laxative for a horse. It was also proven that bran has an inverted Phosphorus to calcium ratio and if fed daily or in high amounts can cause the body to become calcium deficient as it cannot absorb calcium when too much phosphorous is present. Instead of bran mashes you can instead feed warm mashes of hay pellets or another more nutritious feed, or even a small amount of cooked oatmeal. There are many recipes online for non-bran mashes.
Cereals that are low in sugar and sodium. Cheerios, Special K, corn flakes, bran flakes, Grapenuts, and raisin bran are a few commericial cereals that are relatively healthy. Granola (if you can find one low in fat) is healthy, too. Oatmeal, cream of wheat, cream of rice, and grits can be healthy if you don't add too much cream, butter, or sugar.
The most common cause of muffins rising then collapsing is removing them from the oven before they are thoroughly baked. Another possibility is that the oven might not hold a steady heat, allowing the temperature to drop during the baking time. Finally, there might be an error in the proportion of ingredients with not enough or too much soda or baking powder.
Yes vegtable oil or any other cooking oil helps too.
well how much is to many? the answer is it can never be to much of many
