secondary plant substances

What are phytochemicals?

Secondary plant substances are chemical compounds that are formed by plants to protect themselves from pests, diseases or environmental stress. They usually have an intense color, a strong smell or a bitter taste. There are over 100,000 different phytochemicals, which can be divided into different groups, such as

• Carotenoids: these are yellow, orange or red pigments found in carrots, tomatoes or pumpkin, for example. They have antioxidant properties and can strengthen the immune system.
• Flavonoids: These are usually blue or purple pigments found in berries, grapes or red cabbage, for example. They have anti-inflammatory, anti-allergic and vasoprotective effects.
• Glucosinolates: These are sulphur-containing compounds found in cabbage, broccoli and radishes, for example. They have antibacterial, antiviral and anti-cancer effects.
• Phytosterols: These are plant sterols found in nuts, seeds or avocado, for example. They have cholesterol-lowering and immunomodulating effects.
• Saponins: These are foam-forming compounds found in legumes, oats and quinoa, for example. They have cholesterol-binding and blood sugar-lowering effects.

How do phytochemicals affect dogs?

Secondary plant substances can also have health-promoting effects for dogs if they are consumed in moderate amounts. For example, they can support the immune system, inhibit inflammation, neutralize free radicals or reduce the risk of certain diseases.

However, phytochemicals can also have undesirable side effects if they are administered in excessive doses or over a longer period of time. For example, they can disrupt digestion, trigger allergies or impair the absorption of other nutrients.

How can you offer your dog phytochemicals?

If you want to offer your dog phytochemicals, you should bear a few points in mind:

• Only choose plant-based foods that are suitable and tolerated by dogs. For example, avoid onions, garlic, grapes or chocolate, which can be toxic to dogs.
• Only give your dog small amounts of plant-based foods and gradually introduce them into his diet. Observe his reaction and adjust the amount if necessary.
• Prepare the plant-based foods so that they are easier for your dog to digest. For example, you can boil, steam or puree them.
• Combine the plant-based foods with other high-quality protein sources and fats. For example, you can offer your dog some cooked vegetables with chicken or salmon.
