A common question among people who are trying to lose weight is, "Is corn a vegetable?"
Is Corn a Vegetables are from the leaves, stems, and other parts of a plant. Grains, on the other hand, are from the seed or flower part of a plant.
This makes it confusing when a person wants to count their fruit and veggie intake, and see whether they’re splurging too much on a few kernels of corn.
What is a vegetable?
Vegetables are the edible portions of plants, including leaves (spinach and lettuce), stems (asparagus), roots (carrots), bulbs (onions), flowers (cauliflower and broccoli) and seeds (peas and beans).
Vegetable classification is often based on how a food is eaten. Typically, vegetables are consumed during the main portion of a meal to complement starchy foods.
In the United States, the USDA defines a vegetable as “a usually herbaceous plant grown for an edible part that is usually eaten as part of a meal. It is an important part of a healthy diet.”
What is a grain?
A grain is a seed that's grown for its edible parts (germ, bran, endosperm). Grains are efficient at turning sunlight, water and fertilizer into plant food.
Whole grains are a source of protein, vitamins and minerals like thiamin, riboflavin, vitamin B6, folate, iron, selenium and copper. They're also low-glycemic foods that won't cause sharp spikes in blood sugar levels.
Refined grains have been milled, a process that removes the bran and germ to make them more shelf-stable. But they also strip away dietary fiber, iron and many B vitamins.
What is a fruit?
In biology, a fruit is a plant structure that contains seeds. These fruits are the means by which flowering plants disseminate their seeds, and also serve as food for animals that eat them.
In general, a fruit develops from a plant’s flower, which consists of reproductive structures called ovaries. Some flowers contain just one ovary, while others have multiple.
Berries, such as blueberries and bananas, are formed from a single ovary with multiple seeds embedded in the flesh. Other true berries include cucumbers, tomatoes, grapes and avocados.
What is a starchy vegetable?
A starchy vegetable is a type of vegetable that contains carbohydrates (starches). These are foods your body breaks down into glucose, which is the main energy source for your cells.
If you have diabetes or are following a low-carb weight loss plan, it’s important to limit your intake of starchy vegetables. This is because they raise your blood sugar more than non-starchy vegetables.
Ideally, your starchy vegetables should be cooked in healthy ways, such as baked, boiled, steamed or microwaved, to reduce their carb content. They’re also better sources of fiber, an indigestible complex carb that regulates bowel function, keeps your blood sugar in check and promotes heart health.
What is a starchy grain?
A starchy grain is any food that contains carbohydrates (sugars, fiber or starch). Carbohydrates are a source of energy for the body and are essential for brain function.
When digested, starchy grains break down into glucose molecules and enter the bloodstream. The glucose is then used by the body to power organs, muscles and the brain.
Depending on the botanical source and environmental conditions, starch granules can be very different in shape and size. For example, rice starch granules are very angular (polyhedral), while potato starch granules are oval or circular.
As starchy grains can be identified by their unique morphology, they are often useful for identifying specific species in archaeological remains. Features that allow identification include: hilum, layering, birefringence and extinction cross, and testing for presence of starch using iodine.
