Food is the substance we eat to provide ourselves with the nutrients we need to stay healthy. It can come from a variety of sources, including plants, animals, and even fungal matter. It contains important vitamins and nutrients that help the body to perform at its best. Many foods have anticancer properties as well. It is important to learn about the differences in the different types of food so you can make the best choices for your health.
Science of food
Food science is the study of food and its processes. Its scope overlaps agricultural and nutritional science and leads to the development of food technology.
Influence of culture on eating habits
Food habits vary widely across cultures, with differences in the way food is cooked, consumed, and disposed of. For instance, French cuisine is different from that of Americans. And, of course, different cultures have different traditions about what food is considered acceptable. Still, people from various cultures practice their traditional food habits, and others have adopted the habits of other cultures.
Nutritional value of foods
Nutritional value is an important aspect of food quality. It measures how well-balanced a particular food is in terms of essential nutrients, such as carbohydrates, fat, protein, vitamins, and minerals. It compares the nutrient content of a food to the nutrient needs of the consumer.
Anticarcinogenic properties of some foods
Several food compounds are known to be anticarcinogenic. These compounds are found in large quantities in plants and animals and are a source of cancer-fighting agents. The anti-cancer properties of foods are determined by the additive or antagonistic actions of individual compounds on intracellular oncogenic pathways. For example, tea contains high levels of catechins and terpenoids, both of which have anti-cancer effects. These compounds inhibit cancer cell growth by inducing apoptosis, suppress inflammation and arrest the cancer cell cycle.
Sources of nutrients in foods
Foods rich in nutrients such as vitamins and minerals can support a healthy diet. There are many sources of these nutrients, including whole grains, legumes, and vegetables. These foods are the foundation for a healthy diet. They can also contain hidden nutrient surprises.
